Input: Abstract: The study reported here provides information on National Board of Medical Examiners (NBME) examination policies from all U.S. medical schools (n = 67) that require students to pass the examination. Most of these schools have similar policies on use of a 380 total score as the passing level for the NBME Part I examination, allowing three attempts to pass the examination, interrupting a student's progress into the clinical curriculum upon failure of the examination, officially providing time for preparation for taking the test, and requiring students to pass the Part II examination.
