Abstract
The purpose of this study was to compare the Physician Assistant
Clinical Knowledge Rating and Assessment Tool (PACKRAT) and the Objective Structured
Clinical Examination (OSCE) as predictors of performance on the Physician Assistant National
Certifying Examination (PANCE). In order to become a licensed physician assistant one must
graduate from an accredited program and pass the PANCE. Physician assistant programs use
several methods to evaluate students and prepare students to take the PANCE. These methods
include exams such as the PACKRAT and the OSCE. Due to the fact that the PACKRAT and the
OSCE are being used for this purpose, it is imperative to know the predictive value of these exams
on the PANCE. Methods: The study data used in this investigation were collected on 84 WSU PA Program graduates of 2003 and 2004 who have taken the PANCE. The identified set of
explanatory variables include PACKRAT I, PACKRAT II, OSCE I, OSCE II, and PANCE scores.
Correlation analysis was conducted comparing PACKRAT I and PANCE, PACKRAT II and
PANCE, OSCE I and PANCE, and OSCE II and PANCE using linear models to determine how
the scores relate. Logistic regression was used to assess the capability of PACKRAT I,
PACKRAT II, OSCE I, and OSCE II to predict the PANCE score. Results: PACKRAT and
PANCE scores were shown to be highly correlated. OSCE and PANCE scores were also
correlated, but to a lesser degree. Linear regression revealed a significant relationship between the
PACKRAT and PANCE, with 58% of variance in PANCE scores being accounted for by the
variance in PACKRAT scores. The OSCE scores accounted for 19% of variance in PANCE
scores. Conclusion: Both the PACKRAT and OSCE scores were predictive of PANCE scores.
The PACKRAT was more predictive of the PANCE than the OSCE.
