The ABFM exam, the American Board of Family Medicine’s Family Medicine Certification Examination, is a one-day, 300-question test you must pass for initial board certification. It runs every April and November at Prometric centers, in four 95-minute sections with 100 minutes of pooled break time. AAFP says it cost most residents $1,300 in 2024. After that, you keep certification on a five-year cycle, meeting the exam requirement with either a quarterly longitudinal assessment or the one-day exam.
