What is the difference between the GS and NAF pay systems?
The GS (General Schedule) pay system applies to Civil Service appropriated fund jobs. It is established by law and does not apply to Department of Defense Nonappropriated Fund jobs. The GS schedule consists of 15 grades, each grade having 10 steps/rates. Employees start at the step 1 salary and progress through 10 salary rates within the grade based on time in grade (not performance). The NAF pay schedules are developed by the Department of Defense for Non-appropriated fund jobs. The schedules consist of 6 broad bands. Pay is set within a range based on employee skills and private sector considerations, and subsequent pay increases based on performance (not time in grade).
