DEREGISTRATION OF UNSOLD SECURITIES

This Post-Effective Amendment No. 2 relates to the following Registration Statement on Form S-3 (the “Registration Statement”) of National Technical Systems, Inc. (the “Registrant”):

File No. 333-152615 pertaining to the registration for resale by the holders thereof of 358,713 shares of Common Stock, no par value per share, of the Registrant, which was originally filed with the Securities and Exchange Commission (the “Commission”) on July 29, 2008, as amended by Post-Effective Amendment No. 1 filed on August 21, 2008.

On August 15, 2013, the Registrant entered into an Agreement and Plan of Merger with Nest Parent, Inc., a Delaware corporation (“Parent”), and Nest Merger Sub, Inc., a California corporation and wholly owned subsidiary of Parent (“Merger Sub”), which was approved by the shareholders of the Registrant at a duly convened special meeting on November 19, 2013. The Registrant and Merger Sub subsequently filed an Agreement of Merger with the California Secretary of State on November 22, 2013, as a result of which Merger Sub merged with and into the Registrant, with the Registrant continuing as the surviving company after the merger as a wholly owned subsidiary of Parent. As a result of the merger, any offering pursuant to the Registration Statement has been terminated. In accordance with the undertaking made by the Registrant in the Registration Statement to remove from registration, by means of a post-effective amendment, any of the securities registered under the Registration Statement which remain unsold at the termination of the offering, the Registrant hereby files this Post-Effective Amendment No. 2 to remove from registration all shares registered under the Registration Statement that remained unsold as of the date of this Post-Effective Amendment No. 2.
