1 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. The format of the OSCE varies by institution and program, but is generally comprised of numerous stations at which students perform various tasks such as history taking, physical exams, laboratory investigation and interpretation. It is a 225 multiple-choice question examination, modeled from the PANCE blueprint. The PACKRAT was developed by a group of PA educators and clinicians in 1996. These methods include exams such as the PACKRAT and the OSCE. PA programs use several methods to evaluate students and prepare students to take the PANCE. As part of preparing students for clinical practice, PA programs strive to prepare students for the PANCE, as passing rates are increasingly being used to measure the quality of a PA program. In order to become a licensed PA one must graduate from an accredited program and pass the PANCE. PAs exercise autonomy in medical decision making, providing a broad range of diagnostic and therapeutic services in a variety of practice settings. BACKGROUND AND PURPOSE BACKGROUND AND PURPOSE Physician Assistants are health professionals licensed to practice medicine with physician supervision. The OSCE scores accounted for 19% of variance in PANCE scores. Linear regression revealed a significant relationship between the PACKRAT and PANCE, with 59% of variance in PANCE scores being accounted for by the variance in PACKRAT scores. OSCE and PANCE scores also correlated, but to a lesser degree. PACKRAT and PANCE scores were shown to be highly correlated. Students in this study had an overall first time pass rate on the PANCE of 95% (class of 2003) and 90% (class of 2004). There was no significant difference in mean scores between the two classes as determined by independent samples t-test.

The PACKRAT was more predictive of the PANCE than the OSCE. Conclusion: Both the PACKRAT and OSCE scores were predictive of PANCE scores. ![]() Linear regression revealed a relationship between the PACKRAT and PANCE as well as the OSCE and the PANCE. OSCE and PANCE scores were correlated, but to a lesser degree. Results: PACKRAT and PANCE scores were shown to be highly correlated. Correlation analysis was conducted comparing PACKRAT I, PACKRAT II, OSCE I, and OSCE II to PANCE using linear models to determine how the scores relate. ![]() The identified set of explanatory variables used included PACKRAT I and II, OSCE I and II, and PANCE scores. Methods: The data were collected on 84 WSU PA Program graduates of 20 who had taken the PANCE. Due to the fact that the PACKRAT and the OSCE are being used to evaluate and prepare students to take the PANCE, it is imperative to know the predictive value of these exams on the PANCE. To become a licensed physician assistant (PA) one must graduate from an accredited program and pass the PANCE. THE OSCE COMPARED TO THE PACKRAT AS A PREDICTOR OF THE OSCE COMPARED TO THE PACKRAT AS A PREDICTOR OF PERFORMANCE ON THE PANCE PERFORMANCE ON THE PANCE Barbara Oberle, PA-S and Richard Muma, PhD, MPH, PA-C Department of Physician Assistant, College of Health Professions ABSTRACT ABSTRACT Background: 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).
