process; information on the number of times an applicant repeats a course is valuable
information when determining the true grade point average.
2. Findings in the study related to the correlation between entry-level skills
and exit-skills were disappointing. It was expected that a statistically significant
correlation would be demonstrated between entry-level skills and exit-level skills.
The unexpected finding can be contributed to the fact that skills learned during
training served as a source of knowledge which was not taken into consideration
during the investigation.
3. The sample size for this investigation was also a limitation for this study.
Chi-square test frequently had expected cell size of less than five which indicated
that the probabilities estimated were not sufficiently precise. Differences in sample
sizes in the t-Test analyses affect the significance of the data analysis.
Future Research
Future research is definitely warranted to further investigate the reliability
and predictive validity of predictor measurers in identifying individual with the
ability to succeed in the physician assistant program. This investigation will serve as
a prelude for a more in depth study that will hopefully demonstrate a more reliable
and valid outcome.

average and the cumulative grade point average future research should incorporate
and establish a more accurate calculation for the cumulative grade point average to
include all course work completed, a science grade point average to include the

| 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. |
