Background: In 1993, the Family and Medical Leave Act (FMLA) mandated 12 weeks of unpaid, job-protected leave. The current impact of taking 12 weeks of leave during residency has not been evaluated. Methods: We examined the 2018 Accreditation Council for Graduate Medical Education (n ¼ 24) specialty leave policies to determine the impact of 6-and 12-week leave on residency training, board eligibility, and fellowship training. We compared our findings with a 2006 study. Results: In 2018, five (21%) specialties had policy language regarding parental leave during residency, and four (16%) had language regarding medical leave. Median leave allowed was 4 weeks (IQR 4-6). Six specialties (25%) decreased the number of weeks allowed for leave from 2006 to 2018. In 2006, a 6-week leave would cause a 1-year delay in board eligibility in six specialties; in 2018, it would not cause delayed board eligibility in any specialty. In 2018, a 12-week (FMLA) leave would extend training by a median of 6 weeks (mean 4.1, range 0-8), would delay board eligibility by 6-12 months in three programs (mean 2.25, range 0-12), and would delay fellowship training by at least 1 year in 17 specialties (71%). The impact of a 12-week leave was similar between medical and surgical specialties. Conclusions: While leave policies have improved since 2006, most specialties allow for 6 weeks of leave, less than half of what is mandated by the FMLA. Moreover, a 12-week,
