The Senior Executive Service (SES) is a position classification in the civil service of the United States federal government equivalent to general officer or flag officer rank in the U.S. Armed Forces. It was created in 1979 when the Civil Service Reform Act of 1978 went into effect under President Jimmy Carter. Characteristics According to the Office of Personnel Management, the SES was designed to be a corps of executives selected for their leadership qualifications, serving in key positions just below the top presidential appointees as a link between them and the rest of the federal (civil service) workforce. SES positions are considered to be above the GS-15 level of the General Schedule, and below Level III of the Executive Schedule. Career members of the SES ranks are eligible for the Presidential Rank Awards program. Up to 10% of SES positions can be filled as political appointments rather than by career employees. About half of the SES is designated "Career Reserved", which can only be filled by career employees. The other half is designated "General", which can be filled by either career employees or political appointments as desired by the administration. Due to the 10% limitation, most General positions are still filled by career appointees. Senior level employees of several agencies are exempt from the SES but have their own senior executive positions; these include the Federal Bureau of Investigation, Central Intelligence Agency, Defense Intelligence Agency, National Security Agency, Transportation Security Administration, Federal Aviation Administration, Government Accountability Office, Members of the Foreign Service, and government corporations. Adverse actions SES career appointees have civil service protections; they may only be fired or suspended for more than 14 days for misconduct, neglect of duty, malfeasance, or failure to accept a directed reassignment or to accompany a position in a transfer of function. These adverse actions may be appealed to the Merit Systems Protection Board. An SES career appointee can also be reassigned within the SES, or from the SES into a competitive service position, based on performance ratings. A single unsatisfactory performance rating makes them eligible for reassignment, though it is not mandatory. However, they must be removed from the SES if they receive two unsatisfactory ratings in a period of five consecutive years, or two less than fully successful ratings within three consecutive years. Reassignments may not be appealed to the Merit Systems Protection Board. SES career appointees in the United
