Using a mailed questionnaire, we surveyed the directors of 41 approved preprofessional practice programs (AP4) listed in the Directory of Dietetic Programs 1990 and nine programs approved by The American Dietetic Association's Council on Education in December 1989 to determine the relative importance of admission criteria used to select students for AP4s. We compared the results of this study with those of an earlier survey of dietetic internship directors. The AP4 and dietetic internship directors gave significantly different importance ratings to elective courses in professional sciences and courses in the biological/physical sciences. Unlike dietetic internship directors, AP4 directors rated Graduate Record Examination (GRE) score highest (1.4 +/- 1.7 on a 10-point scale). AP4 directors' rating of grade point average (1.8 +/- 1.3) and professional courses (1.9 +/- 1.2) was similar to the internship directors' rating of these criteria (1.7 +/- 0.9 and 1.7 +/- 1.0, respectively). Results indicate that AP4 and internship directors seek similar qualities in students, but that GRE score is more important to AP4 directors. The AP4 directors' emphasis on GRE score may be explained, in part, by the fact that 76% (38 of 50) of these programs are affiliated with a university program, and of those 38 programs, 29 (88%) require graduate credit as a component of the AP4. These data are important to Plan IV/V faculty advisers because students may have misconceptions about differences in AP4 and internship selection criteria.
