With the initiation of increased federal spending on programs to prepare nurses in the expanding role, through program evaluators descriptive data has become available on many program graduates. In much of this research, the number of cases limits the generalizations that can be made from these data. In addition, generalizations are difficult when comparing programs because the data do not “match.” With this issue, we begin a four part series of the program evaluation of the graduates of The Pediatric Nurse Practitioner Program at Washington University. It is hoped that by publishing these and similar articles, models for evaluation can be developed to yield comparable data. Fifty graduates of one PNP program were surveyed to determine their practice settings and patient responsibilities. The PNP's were younger, more highly educated and more likely to work in ambulatory care settings than nurses in general. Seventy-eight percent were actively employed as PNP's. They saw a median of 13 off ice patients per day. The majority independently performed all 19 functions on a list of tasks common to pediatric practice which are within the PNP's scope of practice and independently managed 15 of 18 common pediatric problems. Although the PNP's functioned fairly autonomously, 85% had physicians available for consultation more than 75% of the time.
