Question: opm how do step increases work?
Answer: Within-grade step increases are based on an acceptable level of performance and longevity (waiting periods of 1 year at steps 1-3, 2 years at steps 4-6, and 3 years at steps 7-9). It normally takes 18 years to advance from step 1 to step 10 within a single GS grade if an employee remains in that single grade.
