Requirements verified from program websites as of May 2026. Requirements change annually — always confirm directly with each program before applying. Days remaining calculated from the earliest listed deadline where available. LEAP-flagged programs participate in Case Western Reserve's Leadership Excel and Achievement Program, a one-year certificate pathway for previously rejected applicants that leads to guaranteed admission at a partner program; entries marked LEAP* are newer additions that should be verified against Case Western's current affiliate list. PICU-flagged programs explicitly accept Pediatric Intensive Care Unit experience in lieu of adult ICU; entries marked PICU* do not explicitly state PICU acceptance on their admissions pages and should be verified directly with the program before applying. PACU-flagged programs accept Post-Anesthesia Care Unit experience, but in every case this is conditional on the applicant demonstrating routine management of ventilators, vasoactive infusions, and invasive monitoring — most PACU roles do not meet this standard. Entries marked PACU* are conditional or come from a secondary source and should be verified directly with the program before applying. ED-flagged programs define critical care experience by clinical skills rather than by unit and do not exclude emergency department experience, so high-acuity ED experience may be considered if it demonstrates routine management of unstable patients, ventilators, invasive monitoring, and vasoactive infusions; this is not a guarantee of acceptance and should be verified directly with each program.
