Section 430.401 - Purpose(a) This subpart implements 5 U.S.C. 5307(d) , as added by section 1322 of the Chief Human Capital Officers Act of 2002 ( Title XIII of Public Law 107-296 , the Homeland Security Act of 2002; November 25, 2002), which provides a higher aggregate limitation on pay for certain members of the Senior Executive Service (SES) under 5 U.S.C. 5382 and 5383 and employees in senior-level (SL) and scientific or professional (ST) positions paid under 5 U.S.C. 5376 . In addition, this subpart is necessary to administer rates of basic pay for members of the SES under 5 U.S.C. 5382 , as amended by section 1125 of the National Defense Authorization Act for Fiscal Year 2004. The regulations in this subpart strengthen the application of pay-for-performance principles to senior executives and senior professionals. Specifically, the statutory provisions authorize an agency to apply a higher maximum rate of basic pay for senior executives (consistent with 5 CFR part 534 , subpart D, when effective) and apply a higher aggregate limitation on pay (consistent with 5 CFR part 530 , subpart B) to its senior employees, but only after OPM, with OMB concurrence, has certified that the design and application of the agency's appraisal systems for these employees make meaningful distinctions based on relative performance. This subpart establishes the certification criteria and procedures that OPM will apply in considering agency requests for such certification.(b) Senior executives generally may receive an annual rate of basic pay up to the rate for level III of the Executive Schedule under 5 U.S.C. 5382 and 5 CFR part 534 , subpart D, when effective. Senior employees generally may receive total compensation in a calendar year up to the rate for level I of the Executive Schedule under 5 U.S.C. 5307(a) and 5 CFR 530.203(a) . Only employees covered by an appraisal system that OPM, with OMB concurrence, certifies under this subpart are eligible for a maximum annual rate of basic pay for senior executives up to the rate for level II of the Executive Schedule (consistent with 5 U.S.C. 5382 and 5 CFR part 534 , subpart D, when effective) and a higher aggregate pay limitation equivalent to the total annual compensation payable to the Vice President (consistent with 5 U.S.C. 5307(d) and 5 CFR 530.203(b) ) .
