Item 4.01.                                        Changes in Registrant’s Certifying Accountant.

(a) Dismissal of Independent Registered Public Accountant

Willdan Group, Inc. (“Willdan”) has dismissed Ernst & Young LLP (“Ernst & Young”), an independent registered public accounting firm, as its principal accountant. The decision to dismiss Ernst & Young was effective on April 14, 2015, after being recommended by Willdan’s audit committee and approved by Willdan’s board of directors (the “Board”).

The reports of Ernst & Young on Willdan’s consolidated financial statements for the fiscal years ended January 2, 2015 and December 27, 2013 did not contain an adverse opinion or disclaimer of opinion, and such reports were not qualified or modified as to uncertainty, audit scope, or accounting principle.

During Willdan’s fiscal years ended January 2, 2015 and December 27, 2013, and the interim period from January 3, 2015, through and including April 14, 2015, the date of Ernst & Young’s dismissal, (i) there were no disagreements (as that term is defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) between Willdan and Ernst & Young on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which, if not resolved to the satisfaction of Ernst & Young, would have caused Ernst & Young to make reference to the subject matter of the disagreement in connection with its reports on Willdan’s consolidated financial statements for such years or any subsequent interim period through the date of dismissal, and (ii) there were no “reportable events” (as defined in Item 304(a)(1)(v) of Regulation S-K).

Willdan provided Ernst & Young with a copy of this Form 8-K and requested that, as promptly as possible, Ernst & Young provide Willdan with a letter addressed to the Securities and Exchange Commission (the “SEC”) stating whether it agrees with the above statements and, if not, stating the respects in which it does not agree. Willdan will file Ernst & Young’s letter with the SEC as an exhibit to an amendment to this Current Report on Form 8-K within two business days of receipt thereof.

(b) Newly Appointed Independent Registered Public Accountant

On April 14, 2015, following the recommendation of Willdan’s audit committee, the Board approved the engagement of KPMG LLP (“KPMG”), an independent registered public accounting firm, as its principal accountant to perform independent audit services beginning with the fiscal year ending January 1, 2016. During Willdan’s fiscal years ended January 2, 2015 and December 27, 2013, and the interim period from January 3, 2015, through and including the April 14, 2015, the date of KPMG’s engagement, neither Willdan, nor anyone acting on its behalf, consulted KPMG regarding either (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered with respect to the consolidated financial statements of Willdan, in any case where a written report or oral advice was provided to Willdan by KPMG that KPMG concluded was an important factor considered by Willdan in reaching a decision as to any accounting, auditing or financial reporting issue; or (ii) any matter that was the subject of a disagreement (as that term is defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions to Item 304 of Regulation S-K) or a “reportable event” (as that term is described in Item 304(a)(1)(v) of Regulation S-K).

Willdan’s stockholders entitled to vote at Willdan’s Annual Meeting of Stockholders to be held in June of this year will be asked to ratify the selection of KPMG as Willdan’s principal accountant for the fiscal year ended January 1, 2016.
