By the early 1980s,
nurse practitioner education moved into graduate programs and by 1981, most
states required graduate degrees for nurse practitioner practice. In response to the scientific knowledge
explosion, programs kept adding new courses, expanding their length and their
credit loads. By the turn of the 21st century, most nurse
practitioner programs credit hours far exceeded those in other graduate
programs. At the same time there was a growing movement towards practice doctorates
in other professions and this led educators to think about new types of nurse
practitioner programs. By 2005, the Doctorate of Nursing Practice (DNP) became
the newest level of practitioner training, giving credit for the breadth of
content in the nurse practitioner programs.
