By the end of the 1970s, the majority of physician assistants in practice were ex-military medical corps, and in the public's mind, a physician assistant was associated with a corpsman. 2,3 In the last 50 years since the introduction of the first physician assistant program, education and board certification requirements have become increasingly standardized, with now more than 230 physician assistant schools across the country.

Their intent was to train graduate pediatric nurses to provide comprehensive child wellness care and manage common childhood health problems, especially in the rural areas of Colorado. Initially, the introduction of this new role to advance nursing
