Introduction This study's aim was to examine prerequisite course requirements and compare them to previous studies with a secondary aim to examine potential differences relative to program characteristics.Methods Data were extracted from the websites of 265 entry-level physician assistant (PA) programs from October 2020 until December 2020. Course prerequisites as well as number of courses and semester hours required were described and examined according to program location, phase, Carnegie Classification, association with a medical school, and the public/private status of the sponsoring institution.Results Of 264 PA programs, more than 50% of programs required 6 common prerequisites: anatomy, physiology, microbiology, statistics, general chemistry, and psychology. The total number of unique prerequisite courses was 28 for all programs with a reduction in humanities and social sciences semester hours compared to previous studies and a slight increase in credit hours required for the common 6 courses. Total prerequisite hours and courses required were higher for master's programs; private, not-for-profit programs; newly established programs; and those not associated with a medical school. Newer programs are generally located in private, not-for-profit educational institutions that are not associated with a medical school. Programs in the Mountain Division required a lower number of prerequisites, and the South Region required the greatest number of prerequisite courses and semester hours.Discussion The present study demonstrates a difference in prerequisite requirements across the country. This could translate to increased cost and a potential barrier to those considering a career as a PA.

Introduction The purpose of this study was to explore the relationship between program characteristics and attrition rates. Methods Program graduation rates, attrition rates, and Physician Assistant National Certifying Examination (PANCE) pass rates were extracted from program websites from February-March 2021 and summarized for 2018, 2019, and 2020. Means were compared across categories of independent variables. Attrition rates and PANCE pass rates were correlated. Prerequisites and attrition rate were evaluated with multiple regression. Results Mean attrition rates varied little across years. Significant differences in mean attrition were limited to a few US Census Bureau regions or divisions. No significant correlation between the total number of prerequisite courses or total prerequisite credits and attrition existed. In 2020, mean attrition rate was statistically significantly greater when biochemistry was required (M = 6.89, SD = 7.04) than when not required (M = 4.91, SD = 4.75) and was statistically significantly lower when an additional chemistry course was required (M = 3.65, SD = 4.00) than when not required (M = 5.93, SD = 5.82). No significant predictors of attrition were found with regression. Discussion The mean attrition rates have been relatively stable from 2018–2020, suggesting that the presence of prerequisite coursework has no significant impact on attrition rates. This suggests that specific prerequisites may not predict success in a program, supporting the idea of decreasing or eliminating prerequisites. Additional studies are needed to understand the factors, including specific combinations of prerequisites, that predict completion of a physician assistant program.
