Basic sciences (~2 years)
The first 4–5 semesters cover foundational sciences: anatomy, physiology, biochemistry, pharmacology, pathology, microbiology, behavioral sciences, and clinical skills. Most schools embed dedicated USMLE Step 1 preparation from semester one and require a comprehensive NBME assessment before advancing to clinicals. This phase is typically delivered on a single main campus and follows a structured, semester-based system similar to the pre-clinical years at US medical schools, often supplemented with small-group problem-based learning and early clinical skills sessions using standardized patients. Because Step 1 has shifted to pass/fail reporting, many schools now emphasize building a strong foundation for Step 2 CK performance earlier in the curriculum, integrating clinical correlations into basic science coursework rather than treating them as separate tracks. Attrition is concentrated in this phase at many institutions, since the volume and pace of material mirror the demands of US basic science curricula without the same institutional support systems some students are used to. Students who struggle with the NBME comprehensive benchmark exam required for advancement may face remediation, a delayed start to clinicals, or dismissal, depending on the school's policies. Prospective students should ask schools directly what percentage of a given entering cohort successfully advances to clinical rotations within the standard timeline, since this figure is a much better proxy for curriculum difficulty than admissions statistics alone.
Clinical rotations (~2 years)
Clinical rotations include roughly 48–56 weeks of core rotations (medicine, surgery, pediatrics, OB/GYN, psychiatry, family medicine) followed by 20–30 weeks of electives. USMLE Step 2 CK is usually taken during or shortly after core rotations. Core rotations are typically completed in a fixed sequence at affiliated teaching hospitals, and scheduling is largely determined by the school rather than the student, since hospital capacity and rotation slot availability drive placement. Electives, by contrast, give students meaningful control over their trajectory: a student targeting anesthesiology or radiology can use elective time to rotate in that specialty at institutions where they hope to eventually match, building relationships with faculty who may later serve as away-rotation references. Because clinical rotations happen across multiple US cities and hospital systems, students should budget for the logistical reality of moving every few weeks to a few months — short-term housing, licensing paperwork for certain states, and travel between rotation sites all add time and cost that isn't always obvious from published program lengths. Some schools offer more geographically consolidated rotation networks, which reduces the disruption of moving repeatedly, while others operate a wider, more dispersed hospital network that offers variety but demands more logistical flexibility from students during an already demanding stretch of training.
Residency (3–7 years)
Family medicine and internal medicine residencies are 3 years. General surgery is 5. Neurosurgery and cardiothoracic surgery extend further with fellowships. Fellowship training adds another 1–3 years for subspecialties like cardiology, gastroenterology, hematology-oncology, or interventional radiology. For IMG applicants, primary care specialties such as family medicine, internal medicine, and pediatrics have historically offered the most consistent match outcomes, which is part of why they remain the most common landing spots for Caribbean graduates. That said, an increasing number of graduates from top-tier schools are matching into psychiatry, emergency medicine, and even some surgical subspecialties, reflecting both stronger clinical preparation and growing program director familiarity with well-established Caribbean pipelines. The total time from matriculation to independent practice therefore varies considerably depending on the specialty pursued: a student going into family medicine could be practicing roughly seven years after starting medical school, while a student pursuing a surgical subspecialty with fellowship training could be looking at eleven years or more. Because residency length is fixed by specialty regardless of where a student attended medical school, the more relevant question for prospective Caribbean students isn't how long training takes, but which specialties a given school's graduates have realistically been able to match into in recent cycles.
