                               PART III - NARRATIVE

State below in reasonable detail the reasons why Forms 10-K, 20-F, 11-K, 10-Q,
10-D, N-SAR, N-CSR, or the transition report or portion thereof, could not be
filed within the prescribed time period.

Aehr Test Systems (the "Registrant") is unable to file its annual report on
Form 10-K for the period ended May 31, 2009 within the prescribed time period
because the Registrant was unable, without unreasonable effort or expense, to
obtain and analyze the business information necessary to complete the
preparation of the Registrant's financial statements and the review of such
financial statements by the Registrant's auditors in time for filing.

                              PART IV - OTHER INFORMATION

(1) Name and telephone number of person to contact in regard to this

Gary L. Larson, Chief Financial Officer     (510)               623-9400
---------------------------------------   ---------        ------------------
              (Name)                     (Area Code)       (Telephone Number)

(2) Have all other periodic reports required under Section 13 or 15(d) of
    the Securities Exchange Act of 1934 or Section 30 of the Investment
    Company Act of 1940 during the preceding 12 months or for such shorter
    period that the registrant was required to file such report(s) been filed?
    If the answer is no, identify report(s).  [X] Yes [ ] No

(3) Is it anticipated that any significant change in results of operations
    from the corresponding period for the last fiscal year will be reflected
    by the earnings statements to be included in the subject report or portion
    thereof?   [X] Yes [ ] No

If so, attach an explanation of the anticipated change, both narratively and
quantitatively, and, if appropriate, state the reasons why a reasonable
estimate of the results cannot be made.

The Registrant anticipates that in its Form 10-K for the period ended May 31,
2009, it will report significant changes to its net income compared to the
period ended May 31, 2008.  The Registrant anticipates that it will report a
decrease of approximately 45% in revenue and a net loss of approximately $30.0
million for the period ended May 31, 2009 compared to a net income for the
period ended May 31, 2008 of approximately $10.6 million. We believe that the
decrease in net profit for the period ended May 31, 2009 is the result of the
bankruptcy filing of our largest customer and the decline in global demand for
semiconductor equipment, and consists of the following: (1) a reduction in net
sales of $17.6 million; (2)  a provision for bad debt of $13.7 million; (3) a
provision for excess and obsolete inventory of $7.2 million; (4) the
reinstatement of the deferred tax asset valuation allowance of $4.9 million;
(5) cancellation charges of $0.3 million; (6) an impairment of goodwill of $0.3
million; and (6) severance costs of $0.4 million.

                             Aehr Test Systems
                 (Name of Registrant as Specified in Charter)

has caused this notification to be signed on its behalf by the undersigned
thereunto duly authorized.
