5 U.S.C. § 3392

(a) Qualification standards shall be established by the head of each agency for each Senior Executive Service position in the agency— (1) in accordance with requirements established by the Office of Personnel Management, with respect to standards for career reserved positions, and (2) after consultation with the Office, with respect to standards for general positions. (b) Not more than 30 percent of the Senior Executive Service positions authorized under section 3133 of this title may at any time be filled by individuals who did not have 5 years of current continuous service in the civil service immediately preceding their initial appointment to the Senior Executive Service, unless the President certifies to the Congress that the limitation would hinder the efficiency of the Government. In applying the preceding sentence, any break in service of 3 days or less shall be disregarded. (c) (1) If a career appointee is appointed by the President, by and with the advice and consent of the Senate, to a civilian position in the executive branch which is not in the Senior Executive Service, and the rate of basic pay payable for which is equal to or greater than the rate payable for level V of the Executive Schedule, the career appointee may elect (at such time and in such manner as the Office may prescribe) to continue to have the provisions of this title relating to basic pay, performance awards, awarding of ranks, severance pay, leave, and retirement apply as if the career appointee remained in the Senior Executive Service position from which he was appointed. Such provisions shall apply in lieu of the provisions which would otherwise apply— (A) to the extent provided under regulations prescribed by the Office, and (B) so long as the appointee continues to serve under such Presidential appointment. (2) An election under paragraph (1) may also be made by any career appointee who is appointed to a civilian position in the executive branch— (A) which is not in the Senior Executive Service; and (B) which is covered by the Executive Schedule, or the rate of basic pay for which is fixed by statute at a rate equal to 1 of the levels of the Executive Schedule. An election under this paragraph shall remain effective so long as the appointee continues to serve in the same position. (d) Appointment or removal of a person to or from any Senior Executive Service position in an independent regulatory commission shall not be subject, directly or indirectly, to review or approval by any officer or entity within the Executive Office of the President.
