| Organization, Consolidation and Presentation of Financial Statements [Abstract] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Description of Business and Basis of Presentation | Description of Business and Basis of Presentation Description of Business Mistras Group, Inc. and subsidiaries ("the Company") is a leading “one source” global provider of technology-enabled asset protection solutions used to evaluate the structural integrity and reliability of critical energy, industrial and public infrastructure. The Company combines industry-leading products and technologies, expertise in mechanical integrity (MI) and non-destructive testing (NDT) services and proprietary data analysis software to deliver a comprehensive portfolio of customized solutions, ranging from routine inspections to complex, plant-wide asset integrity assessments and management. These mission critical solutions enhance customers’ ability to extend the useful life of their assets, increase productivity, minimize repair costs, comply with governmental safety and environmental regulations, manage risk and avoid catastrophic disasters. The Company serves a global customer base of companies with asset-intensive infrastructure, including companies in the oil and gas, fossil and nuclear power, alternative and renewable energy, public infrastructure, chemicals, commercial aerospace and defense, transportation, primary metals and metalworking, pharmaceutical/biotechnology and food processing industries and research and engineering institutions. Basis of Presentation The condensed consolidated financial statements contained in this report are unaudited. In the opinion of management, the condensed consolidated financial statements include all adjustments, which are of a normal recurring nature, necessary for a fair presentation of the results for the interim periods of the fiscal years ending May 31, 2016 and 2015. Reference to a fiscal year means the fiscal year ended May 31. Certain items included in these statements are based on management’s estimates. Actual results may differ from those estimates. The results of operations for any interim period are not necessarily indicative of the results expected for the year. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the notes to the audited consolidated financial statements contained in the Company’s Annual Report on Form 10-K (“2015 Annual Report”) for fiscal 2015, as filed with the Securities and Exchange Commission on August 12, 2015. Principles of Consolidation The accompanying unaudited condensed consolidated financial statements include the accounts of Mistras Group, Inc. and its wholly and majority-owned subsidiaries. For subsidiaries in which the Company’s ownership interest is less than 100%, the noncontrolling interests are reported in stockholders’ equity in the accompanying condensed consolidated balance sheets. The noncontrolling interests in net income, net of tax, is classified separately in the accompanying condensed consolidated statements of income. All significant intercompany accounts and transactions have been eliminated in consolidation. Mistras Group, Inc.’s and its subsidiaries’ fiscal years end on May 31 except for the subsidiaries in the International segment, which end on April 30. Accordingly, the Company’s International segment subsidiaries are consolidated on a one month lag. Therefore, in the quarter and year of acquisition, results of acquired subsidiaries in the International segment are generally included in consolidated results for one less month than the actual number of months from the acquisition date to the end of the reporting period. Management does not believe that any events occurred during the one-month lag period that would have a material effect on the Company’s condensed consolidated financial statements. Reclassification Certain amounts in prior periods have been reclassified to conform to the current year presentation. Such reclassifications did not have a material effect on the Company's financial condition or results of operations as previously reported. Immaterial Correction Subsequent to the issuance of its interim condensed consolidated financial statements as of and for the three and nine months ended February 28, 2015, the Company identified errors related to the classification of amounts reported in the Condensed Consolidated Statement of Cash Flows for that period. In accordance with the SEC Staff Accounting Bulletin (SAB) No. 99, Materiality, and SAB No. 108, Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements, management evaluated the materiality of the errors from qualitative and quantitative perspectives, and concluded that the errors were immaterial. Accordingly, management has corrected the presentation of the affected line items of the accompanying Condensed Consolidated Statement of Cash Flows for the nine months ended February 28, 2015, as summarized below. These changes did not impact the Company’s net income, balance sheet, or stockholders’ equity for any periods previously reported.
Significant Accounting Policies The Company’s significant accounting policies are disclosed in Note 2 — Summary of Significant Accounting Policies in the Company's 2015 Annual Report. On an ongoing basis, the Company evaluates its estimates and assumptions, including, among other things those related to revenue recognition, valuations of accounts receivable, long-lived assets, goodwill, deferred tax assets and uncertain tax positions. Since the date of the 2015 Annual Report, there have been no material changes to the Company's significant accounting policies. Income Taxes The Company provides for income taxes in interim periods in an amount that aligns its year-to-date tax provision with the effective income tax rate expected for the full year, plus adjustments to certain discrete tax items. During the three months ended February 29, 2016 and February 28, 2015, the Company's effective income tax rate differed from the statutory rate principally due to adjustments to certain discrete tax items related to the resolution and adjustment of certain income tax contingencies, which decreased the effective tax rate by 11% and 8%, respectively. Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board ("FASB") issued ASU No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard is effective for fiscal years and interim periods within those fiscal years beginning December 15, 2017, as a result of a one year deferral in the standard issued by the FASB in August 2015 with ASU 2015-14, Revenue from Contracts with Customers - Deferral of the Effective Date. Early application is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is evaluating the effect that ASU 2014-09 will have on its condensed consolidated financial statements and related disclosures. In September 2015, the FASB issued ASU No. 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments. This amendment will simplify the accounting for adjustments made to provisional amounts recognized in a business combination and eliminates the requirement to retrospectively account for those adjustments in previous reporting periods. This update will require on the face of the income statement or in the notes to the financial statements the amount recorded in current-period earnings that would have previously been recorded if the adjustment to the provisional amounts had been recognized as of the acquisition date. ASU 2015-16 is effective for fiscal years, and interim periods within those fiscal years beginning after December 15, 2015. This update should be applied prospectively and earlier adoption is permitted for financial statements that have not been issued. The Company is evaluating the effect that ASU 2015-16 will have on its condensed consolidated financial statements and related disclosures. In November 2015, the FASB issued ASU No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes. This amendment will simplify the presentation of deferred tax assets and liabilities on the balance sheet and require all deferred tax assets and liabilities to be treated as non-current. ASU 2015-17 is effective for fiscal years, and interim periods within those fiscal years beginning after December 15, 2016, with early adoption permitted. The Company is evaluating the effect that ASU 2015-17 will have on its condensed consolidated financial statements and related disclosures. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). This amendment supersedes previous accounting guidance (Topic 840) and requires all leases, with exception of leases with a term of 12 months or less, to be recorded on the balance sheet as lease assets and lease liabilities. ASU 2016-02 is effective for fiscal years, and interim periods within those fiscal years beginning after December 15, 2018, with early adoption permitted. The standard requires lessees and lessors to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The Company is evaluating the effect that ASU 2016-02 will have on its condensed consolidated financial statements and related disclosures. |

Share-Based Compensation |
9 Months Ended |

| Disclosure of Compensation Related Costs, Share-based Payments [Abstract] | |
| Share-Based Compensation | Share-Based Compensation The Company has share-based incentive awards outstanding to its eligible employees and Directors under two equity incentive plans: (i) the 2007 Stock Option Plan (the 2007 Plan), and (ii) the 2009 Long-Term Incentive Plan (the 2009 Plan). No further awards may be granted under the 2007 Plan, although awards granted under the 2007 Plan remain outstanding in accordance with their terms. Awards granted under the 2009 Plan may be in the form of stock options, restricted stock units and other forms of share-based incentives, including performance restricted stock units, stock appreciation rights and deferred stock rights. Stock Options For the three and nine months ended February 29, 2016 and February 28, 2015, the Company recognized share-based compensation expense related to stock option awards of less than $0.1 million for each period, respectively. As of February 29, 2016, there was less than $0.1 million of unrecognized compensation costs, net of estimated forfeitures, related to stock option awards, which are expected to be recognized over a remaining weighted average period of less than 0.1 years. No stock options were granted during the nine months ended February 29, 2016 and February 28, 2015. Restricted Stock Unit Awards For the three months ended February 29, 2016 and February 28, 2015, the Company recognized share-based compensation expense related to restricted stock unit awards of $1.1 million and $1.2 million, respectively. For the nine months ended February 29, 2016 and February 28, 2015, the Company recognized share-based compensation expense related to restricted stock unit awards of $3.3 million and $3.5 million, respectively. As of February 29, 2016, there was $8.3 million of unrecognized compensation costs, net of estimated forfeitures, related to restricted stock unit awards, which are expected to be recognized over a remaining weighted average period of 2.3 years. During the first nine months of fiscal 2016 and 2015, the Company granted approximately 28,000 and 21,000 shares, respectively, of fully-vested common stock to its five non-employee directors, in connection with its non-employee director compensation plan. These shares had grant date fair values of $0.5 million and $0.4 million, respectively, which was recorded as share-based compensation expense during the nine months ended February 29, 2016 and February 28, 2015, respectively. During the first nine months of fiscal 2016 and 2015, approximately 220,000 and 231,000 restricted stock units, respectively, vested. The fair value of these units was $3.5 million and $5.2 million, respectively. Upon vesting, restricted stock units are generally net share-settled to cover the required minimum withholding tax and the remaining amount is converted into an equivalent number of shares of common stock. Performance Restricted Stock Units In the third quarter of fiscal 2014, the Company granted one-year, two-year and three-year performance restricted stock units to its executive officers and certain other senior officers. In the second quarter of fiscal 2015, the Company granted performance restricted stock units to its executive and certain other senior officers. In the first quarter of fiscal 2016, the Company modified its equity compensation program and granted 154,000 performance restricted stock units to its executive and certain other senior officers. As a condition for receiving any awards under the revised fiscal 2016 plan, the executive and senior officers surrendered and released all rights to receive any shares under the three-year 2014 awards and three-year 2015 awards with a performance or market condition. The Company has accounted for the fiscal 2016 awards as modifications in accordance with ASC 718, Compensation - Stock Compensation. These units have requisite service periods of five years and have no dividend rights. The actual payout of these units will vary based on the Company’s performance over a one-year period based on three metrics related to the Company’s fiscal 2016 performance: (1) Operating Income, (2) Adjusted EBITDAS, which is consistent with Adjusted EBITDA as disclosed in the financial statements, which is net income before interest, taxes, depreciation, amortization, non-cash stock-based compensation expense, acquisition related items, and other non-routine items as determined by the Committee and (3) Revenue. There is also a discretionary portion based on individual performance. During the three months ended November 30, 2015, the Company evaluated the expected performance metrics and increased the estimated performance shares expected to be granted by 80,000 units to a total of 234,000 units. No adjustment was required during the three months ended February 29, 2016. Compensation costs are initially measured assuming that the target performance conditions will be achieved. However, compensation costs related to the performance conditions are adjusted for subsequent changes in the expected outcomes of the performance conditions. The discretionary portion of these awards are liability-classified and adjusted to fair value each reporting period. Compensation costs for the discretionary portion of the awards are recognized over the same five year requisite service period as the awards based on the Company’s fiscal 2016 performance. For the three months ended February 29, 2016 and February 28, 2015, the Company recognized share-based compensation expense/(benefit) related to performance restricted stock units, inclusive of all awards noted above, of approximately $0.4 million and $(0.8) million, respectively. For the nine months ended February 29, 2016 and February 28, 2015, the Company recognized share-based compensation expense related to these units of approximately $1.2 million and $0.9 million, respectively. At February 29, 2016, there was $3.4 million of total unrecognized compensation costs related to the 234,000 non-vested performance restricted stock units, which are expected to be recognized over a remaining weighted average period of 3.8 years. |

| Earnings per Share | Earnings per Share Basic earnings per share is computed by dividing net income by the weighted-average number of shares outstanding during the period. Diluted earnings per share is computed by dividing net income by the sum of (1) the weighted-average number of shares of common stock outstanding during the period, and (2) the dilutive effect of assumed conversion of equity awards using the treasury stock method. With respect to the number of weighted-average shares outstanding (denominator), diluted shares reflects: (i) only the exercise of options to acquire common stock to the extent that the options’ exercise prices are less than the average market price of common shares during the period and (ii) the pro forma vesting of restricted stock units.

| Business Combinations [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Acquisitions | Acquisitions Acquisitions In the first nine months of fiscal 2016, the Company completed one acquisition. The Company purchased a company that provides unmanned aerial systems and NDT services, located in the U.S. In this acquisition, the Company acquired 100% of the common stock of the acquiree in exchange for consideration of $1.8 million in cash and contingent consideration estimated to be $0.9 million to be earned based upon the acquired business achieving specific performance metrics over the initial four years of operations from the acquisition date. The Company accounted for this transaction in accordance with the acquisition method of accounting for business combinations. The assets and liabilities of the business acquired in fiscal 2016 were included in the Company's condensed consolidated balance sheet based upon their estimated fair values on the date of acquisition as determined in a preliminary purchase price allocation, using available information and making assumptions management believes are reasonable. The Company is still in the process of completing its valuation of the assets, both tangible and intangible, and liabilities acquired. The results of operations for this acquisition is included in the Services segment's results from the date of acquisition. The Company's preliminary purchase price allocations are included in the table below, summarizing the estimated fair value of the assets acquired and liabilities assumed at the date of acquisition:
In the first nine months of fiscal 2015, the Company completed four acquisitions. The Company purchased a company, located in Louisiana, a provider of maintenance and inspection services primarily on offshore platforms. This acquisition expanded the service offerings within the Services segment, allowing the Company to provide services to the upstream operations of its customers. The Company also purchased a group of asset protection businesses located in Quebec, Canada and an asset inspection business in Florida to complement service offerings within the Company’s Services segment and continue its market expansion strategy. The Company’s International Segment completed an acquisition of an asset inspection business located in the United Kingdom. In these acquisitions, the Company acquired 100% of the common stock or certain assets of each acquiree in exchange for aggregate consideration of approximately $35.7 million in cash and $20.5 million in notes payable issued as part of the acquisitions. The Company accounted for these transactions in accordance with the acquisition method of accounting for business combinations. In addition, the acquisitions in Quebec and Florida provided for contingent consideration of up to $3.2 million to be earned based upon the acquired business achieving specific performance metrics over the initial two to three years of operation from the acquisition date. The amortization period of intangible assets acquired in fiscal 2015 ranges from 3 to 10 years. The Company recorded $45.2 million of goodwill in connection with these acquisitions, reflecting the strategic fit and revenue and earnings growth potential of these businesses. Acquisition-Related Expense During the three and nine month periods ended February 29, 2016, the Company incurred acquisition-related costs of $0.1 million and $0.2 million, respectively, in connection with due diligence, professional fees, and other expenses for its acquisition activities. Additionally, the Company adjusted the fair value of certain previously recorded acquisition-related contingent consideration liabilities. These adjustments resulted in a net decrease of acquisition-related contingent consideration liabilities and a corresponding increase in income from operations of $0.2 million and $1.3 million, for the three and nine month periods ended February 29, 2016, respectively. The Company’s aggregate acquisition-related contingent consideration liabilities were $3.8 million and $6.4 million as of February 29, 2016 and May 31, 2015, respectively. During the three and nine month periods ended February 28, 2015, the Company incurred acquisition-related costs of $0.2 million in connection with due diligence, professional fees, and other expenses for its acquisition activities. Additionally, the Company adjusted the fair value of certain previously recorded acquisition-related contingent consideration liabilities. For the three and nine month periods ended February 28, 2015, these adjustments resulted in a net decrease of acquisition-related contingent consideration liabilities and a corresponding increase in income from operations of $1.7 million and $3.3 million, respectively. The fair value adjustments to acquisition-related contingent consideration liabilities and the acquisition-related transaction costs have been classified as acquisition-related expense, net, in the condensed consolidated statements of income for the three and nine month periods ended February 29, 2016 and February 28, 2015. |

| Debt Disclosure [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Long-Term Debt | Long-Term Debt Long-term debt consisted of the following:
Senior Credit Facility On October 31, 2014, the Company entered into a Third Amendment and Modification Agreement, to its revolving line of credit, the Third Amended and Restated Credit Agreement (“Credit Agreement”) with Bank of America, N.A., as agent for the lenders and a lender, and JPMorgan Chase Bank, N.A., Keybank, National Association and TD Bank, N.A., as lenders. The Credit Agreement provides the Company with a $175.0 million revolving line of credit, which, under certain circumstances, the line of credit can be increased to $225.0 million. The Company may borrow up to $30.0 million in non-U.S. Dollar currencies and use up to $10.0 million of the credit limit for the issuance of letters of credit. The Credit Agreement has a maturity date of October 30, 2019. As of February 29, 2016, the Company had borrowings of $71.5 million and a total of $4.5 million of letters of credit outstanding under the Credit Agreement. Loans under the Credit Agreement bear interest at LIBOR plus an applicable LIBOR margin ranging from 1% to 1.75%, or a base rate less a margin of 1.25% to 0.375%, at the option of the Company, based upon the Company’s Funded Debt Leverage Ratio. Funded Debt Leverage Ratio is generally the ratio of (1) all outstanding indebtedness for borrowed money and other interest-bearing indebtedness as of the date of determination to (2) EBITDA (which is (a) net income, less (b) income (or plus loss) from discontinued operations and extraordinary items, plus (c) income tax expenses, plus (d) interest expense, plus (e) depreciation, depletion, and amortization (including non-cash loss on retirement of assets), plus (f) stock compensation expense, less (g) cash expense related to stock compensation, plus or minus certain other adjustments) for the period of four consecutive fiscal quarters immediately preceding the date of determination. The Company has the benefit of the lowest margin if its Funded Debt Leverage Ratio is equal to or less than 0.5 to 1, and the margin increases as the ratio increases, to the maximum margin if the ratio is greater than 2.0 to 1. The Company will also bear additional costs for market disruption, regulatory changes effecting the lenders’ funding costs, and default pricing of an additional 2% interest rate margin on any amounts not paid when due. Amounts borrowed under the Credit Agreement are secured by liens on substantially all of the assets of the Company. The Credit Agreement contains financial covenants requiring that the Company maintain a Funded Debt Leverage Ratio of no greater than 3.25 to 1 and an Interest Coverage Ratio of at least 3.0 to 1. Interest Coverage Ratio means the ratio, as of any date of determination, of (a) EBITDA for the 12 month period immediately preceding the date of determination, to (b) all interest, premium payments, debt discount, fees, charges and related expenses of the Company and its subsidiaries in connection with borrowed money (including capitalized interest) or in connection with the deferred purchase price of assets, in each case to the extent treated as interest in accordance with GAAP, paid during the 12 month period immediately preceding the date of determination. The Credit Agreement also limits the Company’s ability to, among other things, create liens, make investments, incur more indebtedness, merge or consolidate, make dispositions of property, pay dividends and make distributions to stockholders, enter into a new line of business, enter into transactions with affiliates and enter into burdensome agreements. The Credit Agreement does not limit the Company’s ability to acquire other businesses or companies except that the acquired business or company must be in the Company's line of business, the Company must be in compliance with the financial covenants on a pro forma basis after taking into account the acquisition, and, if the acquired business is a separate subsidiary, in certain circumstances the lenders will receive the benefit of a guaranty of the subsidiary and liens on its assets and a pledge of its stock. As of February 29, 2016, the Company was in compliance with the terms of the Credit Agreement, and will continuously monitor its compliance with the covenants contained in its credit agreement. Notes Payable and Other In connection with certain of its acquisitions through fiscal 2015, the Company issued subordinated notes payable to the sellers. The maturity of the notes that remain outstanding range from two to five years from the date of acquisition with stated interest rates ranging from 0% to 4%. The Company has discounted these obligations to reflect a 2% to 4% market interest. Unamortized discount on the notes was de minimis as of February 29, 2016 and May 31, 2015. Amortization is recorded as interest expense in the condensed consolidated statements of income. The Company has evaluated current market conditions and borrower credit quality and has determined that the carrying value of its long-term debt approximates fair value. The fair value of the Company’s notes payable and capital lease obligations approximates their carrying amounts based on anticipated interest rates which management believes would currently be available to the Company for similar issuances of debt. |

| Fair Value Disclosures [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Fair Value Measurements | Fair Value Measurements The Company performs fair value measurements in accordance with the guidance provided by ASC 820, Fair Value Measurements and Disclosures. ASC 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. It also establishes a three level hierarchy that prioritizes the inputs used to measure fair value. The three levels of the hierarchy are defined as follows: Level 1 — Inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date. Level 2 — Observable inputs other than quoted prices included in Level 1, including quoted prices for similar assets or liabilities in active markets, quoted prices for identical assets or liabilities in inactive markets, inputs other than quoted prices that are observable for the asset or liability and inputs derived principally from or corroborated by observable market data. Level 3 — Unobservable inputs reflecting the Company’s own assumptions about inputs that market participants would use in pricing the asset or liability based on the best information available. In accordance with the fair value hierarchy described above, the following table shows the fair value of the Company’s financial liabilities that are required to be remeasured at fair value on a recurring basis:
The fair value of contingent consideration liabilities that was classified as Level 3 in the table above was estimated using a discounted cash flow technique with significant inputs that are not observable in the market and thus represents a Level 3 fair value measurement as defined in ASC 820. The significant inputs in the Level 3 measurement not supported by market activity include the probability assessments of expected future cash flows related to the acquisitions, appropriately discounted considering the uncertainties associated with the obligation, and as calculated in accordance with the terms of the applicable acquisition agreements. |

| Commitments and Contingencies Disclosure [Abstract] | |
| Commitments and Contingencies | Commitments and Contingencies Litigation and Government Investigations The Company is subject to periodic lawsuits, investigations and claims that arise in the ordinary course of business. Although the Company cannot predict with certainty the ultimate resolution of lawsuits, investigations and claims asserted against it, the Company does not believe that any currently pending legal proceeding to which the Company is a party will have a material adverse effect on its business, results of operations, cash flows or financial condition, except for the proceedings described below for which the Company is currently unable to determine the likely outcome or reasonably estimate the amount or range of potential liability estimate. The costs of defense and amounts that may be recovered against the Company in such matters may be covered by insurance, except that the primary claims set forth in the purported class action case in California is excluded from insurance coverage. Litigation and Commercial Claims In April 2015, two separate lawsuits were filed in California as purported class action lawsuits on behalf of current and former Mistras employees. The cases are David Kruger v Mistras Group, Inc., filed in the U.S. District Court for the Eastern District of California and Edgar Viceral v Mistras Group, et al, pending in the U.S. District Court for the Northern District of California. Both cases were originally filed in California state court and were removed to the respective U.S. District Courts for the districts in which the state court cases were filed. These two cases have been consolidated, with Kruger dismissing his case and joining the Viceral case. As part of this consolidation, the claims in the Kruger case that were not part of the Viceral case were added to the Viceral case by the filing of an amended complaint. The consolidated case alleges violations of California statutes primarily, the California Labor Code, and seeks to proceed as a collective action under the U.S. Fair Labor Standards Act. The case is predicated on claims for allegedly missed rest and meal periods, inaccurate wage statements, and failure to pay all wages due, as well as related unfair business practices, and is requesting payment of all damages, including unpaid wages, and various fines and penalties available under California law. The parties met with a mediator on April 5, 2016 but no resolution of the case was reached, though the Company anticipates discussions regarding resolution may continue. The Company is currently unable to determine the likely outcome or reasonably estimate the amount or range of potential liability, if any, related to these matters, and accordingly, has not established any reserves for these matters. During fiscal 2012 and 2013, the Company performed radiography work on the construction of pipeline projects in the U.S. The Company has received notice that the owner of the pipeline projects contends that certain of the x-ray images the Company’s technicians prepared regarding the projects did not meet the code quality interpretation standards required by API (American Petroleum Institute) 1103. The projects' owner is claiming damages as a result of the alleged quality defects of the Company’s x-ray images. No lawsuit has been filed at this time. The Company is currently unable to determine the likely outcome or reasonably estimate the amount or range of potential liability related to this matter, and accordingly, has not established any reserves for this matter. Government Investigations In May 2015, the Company received a notice from the U.S. Environmental Protection Agency (“EPA”) that it performed a preliminary assessment at a leased facility the Company operates in Cudahy, California. Based upon the preliminary assessment, the EPA is conducting an investigation of the site, which includes taking groundwater and soil samples. The purpose of the investigation is to determine whether any hazardous materials were released from the facility. The Company has been informed that certain hazardous materials and pollutants have been found in the ground water in the general vicinity of the site and the EPA is attempting to ascertain the origination or source of these materials and pollutants. Given the historic industrial use of the site, the EPA determined that the site of the Cudahy facility should be examined, along with numerous other sites in the vicinity. At this time, the Company is unable to determine whether it has any liability in connection with this matter and if so, the amount or range of any such liability, and accordingly, has not established any reserves for this matter. In January 2012, the Company received notice of a governmental investigation concerning an environmental incident which occurred in February 2011 outside on the premises of the Cudahy facility. No human injury or property damage was reported or appears to have been caused as a result of this incident. While management cannot predict the ultimate outcome of this matter, based on its internal investigation to date, the Company does not believe the outcome will have a material effect on its financial condition or results of operations. To the Company’s knowledge, this matter has been dormant since fiscal 2012. Acquisition-related contingencies The Company is liable for contingent consideration in connection with certain of its acquisitions. As of February 29, 2016, total potential acquisition-related contingent consideration ranged from zero to approximately $17.8 million and would be payable upon the achievement of specific performance metrics by certain of the acquired companies over the next 3.3 years of operations. See Note 4 - Acquisitions to these condensed consolidated financial statements for further discussion of the Company’s acquisitions. |

| Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
| Basis of Presentation | Basis of Presentation The condensed consolidated financial statements contained in this report are unaudited. In the opinion of management, the condensed consolidated financial statements include all adjustments, which are of a normal recurring nature, necessary for a fair presentation of the results for the interim periods of the fiscal years ending May 31, 2016 and 2015. Reference to a fiscal year means the fiscal year ended May 31. Certain items included in these statements are based on management’s estimates. Actual results may differ from those estimates. The results of operations for any interim period are not necessarily indicative of the results expected for the year. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the notes to the audited consolidated financial statements contained in the Company’s Annual Report on Form 10-K (“2015 Annual Report”) for fiscal 2015, as filed with the Securities and Exchange Commission on August 12, 2015. |
| Principles of Consolidation | Principles of Consolidation The accompanying unaudited condensed consolidated financial statements include the accounts of Mistras Group, Inc. and its wholly and majority-owned subsidiaries. For subsidiaries in which the Company’s ownership interest is less than 100%, the noncontrolling interests are reported in stockholders’ equity in the accompanying condensed consolidated balance sheets. The noncontrolling interests in net income, net of tax, is classified separately in the accompanying condensed consolidated statements of income. All significant intercompany accounts and transactions have been eliminated in consolidation. Mistras Group, Inc.’s and its subsidiaries’ fiscal years end on May 31 except for the subsidiaries in the International segment, which end on April 30. Accordingly, the Company’s International segment subsidiaries are consolidated on a one month lag. Therefore, in the quarter and year of acquisition, results of acquired subsidiaries in the International segment are generally included in consolidated results for one less month than the actual number of months from the acquisition date to the end of the reporting period. Management does not believe that any events occurred during the one-month lag period that would have a material effect on the Company’s condensed consolidated financial statements. |
| Reclassification | Reclassification Certain amounts in prior periods have been reclassified to conform to the current year presentation. Such reclassifications did not have a material effect on the Company's financial condition or results of operations as previously reported. |
| Recent Accounting Pronouncements | Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board ("FASB") issued ASU No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard is effective for fiscal years and interim periods within those fiscal years beginning December 15, 2017, as a result of a one year deferral in the standard issued by the FASB in August 2015 with ASU 2015-14, Revenue from Contracts with Customers - Deferral of the Effective Date. Early application is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is evaluating the effect that ASU 2014-09 will have on its condensed consolidated financial statements and related disclosures. In September 2015, the FASB issued ASU No. 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments. This amendment will simplify the accounting for adjustments made to provisional amounts recognized in a business combination and eliminates the requirement to retrospectively account for those adjustments in previous reporting periods. This update will require on the face of the income statement or in the notes to the financial statements the amount recorded in current-period earnings that would have previously been recorded if the adjustment to the provisional amounts had been recognized as of the acquisition date. ASU 2015-16 is effective for fiscal years, and interim periods within those fiscal years beginning after December 15, 2015. This update should be applied prospectively and earlier adoption is permitted for financial statements that have not been issued. The Company is evaluating the effect that ASU 2015-16 will have on its condensed consolidated financial statements and related disclosures. In November 2015, the FASB issued ASU No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes. This amendment will simplify the presentation of deferred tax assets and liabilities on the balance sheet and require all deferred tax assets and liabilities to be treated as non-current. ASU 2015-17 is effective for fiscal years, and interim periods within those fiscal years beginning after December 15, 2016, with early adoption permitted. The Company is evaluating the effect that ASU 2015-17 will have on its condensed consolidated financial statements and related disclosures. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). This amendment supersedes previous accounting guidance (Topic 840) and requires all leases, with exception of leases with a term of 12 months or less, to be recorded on the balance sheet as lease assets and lease liabilities. ASU 2016-02 is effective for fiscal years, and interim periods within those fiscal years beginning after December 15, 2018, with early adoption permitted. The standard requires lessees and lessors to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The Company is evaluating the effect that ASU 2016-02 will have on its condensed consolidated financial statements and related disclosures. |
| Fair Value Measurements | Fair Value Measurements The Company performs fair value measurements in accordance with the guidance provided by ASC 820, Fair Value Measurements and Disclosures. ASC 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. It also establishes a three level hierarchy that prioritizes the inputs used to measure fair value. The three levels of the hierarchy are defined as follows: Level 1 — Inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date. Level 2 — Observable inputs other than quoted prices included in Level 1, including quoted prices for similar assets or liabilities in active markets, quoted prices for identical assets or liabilities in inactive markets, inputs other than quoted prices that are observable for the asset or liability and inputs derived principally from or corroborated by observable market data. Level 3 — Unobservable inputs reflecting the Company’s own assumptions about inputs that market participants would use in pricing the asset or liability based on the best information available. |
