Human Resources and Security Specialists should use this tool to determine the correct investigation level for any covered position within the U.S. Federal Government.
1. Special base rates for law enforcement officers (LEOS) at grades GS-3 through GS-10 are authorized under section 403 of the Federal Employees Pay Comparability Act of 1990. LEO special base rates are used in the same manner as General Schedule rates except that special rates under 5 U.S.C. 5305 are computed using General Schedule rates unless expressly stated otherwise.
2. A locality rate is used to compute post differentials for foreign areas under 5 U.S.C. 5925(a) and danger pay allowances under 5 U.S.C. 5928 for an employee temporarily working in a foreign area (i.e., the employee is on detail, including a work assignment that places the employee in temporary duty travel status), when the employee’s official worksite is located in a locality pay area. (See 5 CFR 531.610.)
3. A special rate may be used as an employee's highest previous rate only in certain reassignments within the agency and as provided in 5 CFR 531.221(c) and 531.222(c). A locality rate may be used as an employee's highest previous rate only to the extent described in 5 CFR 531.221 and 531.222.
4. Premium pay under 5 U.S.C. 5545(c)(2) for administratively uncontrollable overtime (AUO) work is included in the computations for retirement and life insurance deductions and benefits only if the employee meets the definition of "law enforcement officer" for CSRS or FERS purposes.
5. Use the maximum rate of basic pay for employee's position instead of retained rate. (See 5 CFR 536.307(b).)
6. See promotion rules in 5 CFR 531.214.
7. See promotion rules in 5 CFR 531.214(d)(5).
8. Within-grade increases are computed using "rates of basic pay," as defined in 5 CFR 531.403 to include a GS rate or a LEO special base rate, excluding additional pay of any kind such as locality payments and special rate supplements.
9. If an employee's worksite changes at the same time as possible entitlement to pay retention, the agency must first process a geographic conversion. (See 5 CFR part 536, subpart C.)
10. Answers apply only to the expression of a supervisory differential as a percentage of the GS supervisor's basic pay. To determine eligibility for and the maximum amount of any supervisory differential, the GS supervisor's continuing pay must be compared to the non-GS subordinate's continuing pay. See 5 CFR 575.405(c) and (d) for definitions of "continuing pay."
