Some racial and ethnic groups are underrepresented in the medical field because they face unique barriers to admission to medical school. One admission requirement that can present a barrier for applicants is the physician letter of recommendation (PLOR). Undergraduate students report confusion with the application process and lack of mentorship to be two of their biggest challenges to becoming a doctor. It is especially challenging to those who already have limited access to practicing physicians. Therefore, we hypothesized that in the presence of a PLOR requirement, the diversity of students who apply and matriculate into medical school will be decreased.
