references, the motivation of referee and data protection legislation raise concerns
about the reliability of the referee writing the letter. Motivation of the referee is
uncertain; loyalty to the student and fear of being compromised by recent data
protection legislature are contributors. To improve reliability of reference letters a
medical school in New Zealand adopted a reference system by writing to head
teachers with specific questions and requesting a rating of the candidate’s qualities.
Although no long-term predictive validity study has been done to assess the outcome
of this change, the school believes that it provides valid information and correlates
with other non-cognitive information.
Despite the efforts to improve this assessment tool in the selection process,
the literature suggests that this form of assessment needs further standardization to
be more effective and reliable in predicting student performance. This study will
expand on the existing study by utilizing methods described in the study to improve
the reliability and validity of the letter of reference as a predictor measurement to be
correlated with student performance.

| 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. |
