General Schedule or GS means the classification and pay system established under 5 U.S.C. chapter 51 and subchapter III of chapter 53. It also refers to the pay schedule of GS rates established under 5 U.S.C. 5332, as adjusted under 5 U.S.C. 5303 or other law (including GS rates payable to GM employees). Law enforcement officers (LEOs) receiving LEO special base rates are covered by the GS classification and pay system but receive higher base rates of pay in lieu of GS rates at grades GS-3 through GS-10.
