On October 2004, the American Association of Colleges of Nursing called for doctoral preparation for all advance practice nurses by the year 2015. The decision for improved educational preparation is a response to address a complex health care system. Advanced practice nurses have the advantage of analyzing the educational transitions of other professions. This paper discusses the transitions of pharmacology, physical therapy, and audiology to practice doctorates. The focus is placed on the attitudes, obstacles, and methods of resolution. Findings will be evaluated for lessons that may be extrapolated and applicable to nursing as it transitions to the Doctorate of Nursing Practice.
