Senior Executive Service (SES) The Senior Executive Service (SES) was created by the Civil Service Reform Act of 1978. Congress designed the SES to be an elite corps of managers charged with running the Federal Government. The SES was set up as a separate, gradeless personnel system - distinct from the competitive and excepted services - whose positions are classified above the GS-15 level of the General Schedule. An executive may enter the SES as a career appointee, noncareer appointee, or limited term appointee.
