Congress determines how many PAS and NC-SES appointments the president can make. But the president decides how many PA and Schedule C positions will be in his or her administration. Positions in the PAS category include high-ranking cabinet roles and judiciary appointments. PA positions include the president's executive staff. NC-SES jobs are senior management positions -- typically with titles like deputy undersecretary or bureau director.
How Long Does Medical Residency Training Last? Medical residency is a minimum of three years for primary care physicians and some other specialties, up to five years for some surgical specialties. (Some medical specialties require additional years of fellowship training in addition to the three to five years of residency training.)
That residency, which typically involves grueling 80-hour workweeks, is required even if a doctor previously did a residency in a country with an advanced medical system, like Britain or Japan. The only exception is for doctors who did their residencies in Canada.
