Re:		Administaff, Inc. Form 10-K for the period ended December 31, 2007 File No. 1-13998

Dear Mr. Spirgel:

We are responding to comments received from the staff of the Division of Corporation Finance (“Staff”) of the Securities and Exchange Commission (the “SEC”) by letter dated August 7, 2008 regarding the referenced Report on Form 10-K (“Report”) filed by Administaff, Inc. (“Administaff,” or the “Company”). As noted below, Administaff will undertake to incorporate the Staff’s comments in its future filings under the Securities and Exchange Act of 1934 (the “1934 Act”). For your convenience, our responses are prefaced by the Staff’s corresponding comment in italicized text.

We note your use of an executive compensation study which included an analysis of a peer group of companies. We also note your use of tally sheets in your compensation determinations. In future filings, discuss in more specific detail how this information was used in determining your total compensation package for your named executive officers. For example, if you targeted your total compensation for your named executive officers at the median for the total compensation paid at the peer group of companies, indicate so.

     Administaff Response:

Pursuant to the Staff’s comment, Administaff will discuss, in more specific detail, how peer group information and tally sheets are used in determining the total compensation package for the named executive officers.

Pursuant to the Staff’s request, the Company acknowledges that:

	•		the Company is responsible for the adequacy and accuracy of the disclosure in the filings;
	•		Staff comments or changes to disclosure in response to Staff comments do not foreclose the Commission from taking any action with respect to the filings; and
	•		the Company may not assert Staff comments as a defense in any proceeding initiated by the Commission or any person under the federal securities laws of the United States.

For your convenience, in addition to filing via EDGAR, we are faxing a courtesy copy of this letter of response. If you have any questions regarding our responses or require further information, please contact Dan Herink, Senior Vice President of Legal, General Counsel and Secretary, at 281-312-3364, or me at 281-348-3270.
