Item 7.01. Regulation FD Disclosure.

On May 9, 2005 Administaff, Inc.’s president, Richard G. Rawson, established a new structured, prearranged trading plan to sell a portion of his Administaff common shares over a designated period in accordance with Rule 10b5-1 of the Securities Exchange Act of 1934. Mr. Rawson’s original trading plan expired in March 2005.

Under the new trading plan, two of Mr. Rawson’s family limited partnerships may sell a maximum of 168,000 shares, approximately 13% of current stock holdings, over a two-year period subject to the achievement of predetermined stock prices. The plan has been initiated during the company’s open window for insider transactions.

Rule 10b5-1 permits the implementation of a written plan for selling stock at times when insiders are not in possession of material nonpublic information, and allows them to sell stock on a regular basis and in a non-discretionary manner, regardless of any subsequent material nonpublic information they receive.
