was a better predictor of student performance on the certification examination than
the cumulative GPA.
Academic merit alone should not be the sole bases for admission to health
professional programs. The use of non-cognitive data such as interviews, personal
statements, and letters of reference results in the selection of a better quality of
student (Confer, 1995; Turnbull et. al, 2003). The review of literature related to
admission practices for health professional programs acknowledged the utility of
work experience as a consideration in the selection process, but most studies relating
work experience to student performance was found in MBA admission criteria.
Studies correlating work experience with academic performance demonstrated
conflicting results. McClure, Wells, and Bowerman (1986) demonstrated a positive
correlation between work experience and academic performance in MBA studies. In
contrast Dreher and Ryan (2000, 2002, 2004; Grady et. al, 1996) concluded in their
study that work experience did not relate to GPA in MBA.
Research investigating the utility of reference letters in admission indicated
that predictive validity of personal references was zero (Hughes, 2002) and showed
that letters of references has had little meaning as predictors of student success. The
rationale for these finding is that because they are vague, written with the wrong
intent, and are usually positive because of fear of litigation. Although a letter of
reference is believed to be meaningless, it is still one of the most commonly
requested sources of information use by professional programs (Marvis, 2006).
Letters of reference was used in the admission selection process for the PA program.

| Abstract | The purpose of this investigation was to examine the reliability and predictive validity of the of admission data in predicting student success in completing a community college-based physician assistant program and their performance on the National Certification Examination (NCE). The files of 170 graduates were reviewed and the following data was complied: 1) science grade point average (GPAsci), 2) cumulative grade point average (GPAcum), 3) reference letter ratings, 4) personal statement ratings, and 5) work experience -- each identified as a predictor measure in this study. The criterion measures identified in the study were 1) program completion, 2) performance on the NCE, and 3) skills. Findings demonstrated variations in the degree of relationship among predictor measures and criterion measures. The GPAsci demonstrated the greatest degree of correlation with student outcome in comparison with other predictor measures, which is consistent with previous research. Overall, the research demonstrated that there was practical significance or potentially significance correlations between the majority of the predictor measures. |
