Bridging the Gap: Medical Schools' Transition to Residency Courses and their Graduates' Readiness for Residency.

Transition To Residency (TTR) courses prepare U.S. medical school graduates for residency. Program director assessments of post-graduate year-1 (PGY-1s) readiness for residency ("did not meet [DNM]" vs. "met/exceeded" expectations) were stratified by medical school TTR course presence. Of 9,214 PGY-1s graduating in 2023-2024 from medical schools that completed the TTR Educators survey and participated in the Association of American Medical College Resident Readiness Survey, 2.4% (221/9,214) DNM expectations. Adjusting for specialty, PGY-1s from schools with (vs. without) TTR courses had lower odds of "DNM" expectations (odds ratio 0.62; 95% confidence interval 0.40-0.97). TTR courses may support resident readiness across specialties.
