Accounting Policies [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION The accompanying financial information has been prepared by Aehr Test Systems, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission, or SEC. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States (GAAP) have been condensed or omitted pursuant to such rules and regulations. In the opinion of management, the unaudited condensed consolidated financial statements for the interim periods presented have been prepared on a basis consistent with the May 31, 2015 audited consolidated financial statements and reflect all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation of the condensed consolidated financial position and results of operations as of and for such periods indicated. These unaudited condensed consolidated financial statements and notes thereto should be read in conjunction with the consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the fiscal year ended May 31, 2015. Results for the interim periods presented herein are not necessarily indicative of results which may be reported for any other interim period or for the entire fiscal year.
PRINCIPLES OF CONSOLIDATION	PRINCIPLES OF CONSOLIDATION. The condensed consolidated financial statements include the accounts of Aehr Test Systems and its subsidiaries (collectively, the "Company," "we," "us," and "our"). All significant intercompany balances have been eliminated in consolidation. For the majority owned subsidiary, we reflected the noncontrolling interest of the portion we do not own on our Consolidated Balance Sheets in Shareholders’ Equity and in the Consolidated Statements of Operations.
ACCOUNTING ESTIMATES	ACCOUNTING ESTIMATES. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Estimates are used to account for revenue adjustments, the allowance for doubtful accounts, inventory reserves, income taxes, stock-based compensation expenses, and product warranties, among others. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results could differ materially from those estimates.
