Graduate Physician Assistant Education programs are increasing in size and prevalence in the United States. PA Students are trained in the medical model, but not until only recently there have been standardized instruments to measure student progress versus national data before a student takes their certifying board examination. Many programs are now shifting focus to predicting student performance on national board examinations based upon student performance on national end of rotation examinations.
