Preceptor's grading scale preference for student pharmacy practice experience and assessment of the common grading scale among US schools of pharmacy

The majority of preceptors preferred the letter grading system over the pass/no pass system. Familiarity with this system was a contributing factor, as a significant number of preceptors preferred the grading scale they had as a pharmacy student - the letter grade system. This trend mimics current pharmacy school's grading system, as approximately 2/3 currently use a letter grading system to evaluate IPPE/APPEs.
