Short answer: SGU (St. George's University), Ross University, AUC (American University of the Caribbean), and Saba University are grouped as the "Big 4" because they are the largest, oldest, and most USMLE-recognized Caribbean MD programs with established U.S. residency placement records and Title IV eligibility. Each has a different accreditor — they are not interchangeable.

Why "Big 4"?
The term is informal, but consistently used in medical school advising communities. It reflects:
- Scale — these four programs enroll substantially more students than most other Caribbean schools
- U.S. residency track record — longer history of graduates matching U.S. residency, with more published USMLE pass rate data
- Title IV eligibility — all four participate in U.S. federal financial aid programs
- WFME-recognized accreditation — each is accredited by at least one WFME-recognized body
- ECFMG pathway — all four have established ECFMG certification history
"Big 4" is a descriptor, not an accreditation category or official classification.

Each school at a glance
St. George's University (SGU) — Grenada
SGU is the largest Caribbean medical school by enrollment and has the longest U.S. residency placement history. Its primary accreditor is the GMDC (Grenada Medical and Dental Council), which is WFME-recognized. SGU voluntarily withdrew from CAAM-HP in January 2021 — it is no longer on the CAAM-HP assessed programs list, but retains GMDC accreditation.
Key facts: GMDC accredited through 2030; Title IV yes; multiple intakes per year (January, April, August).

Ross University — Barbados
Ross moved from Dominica to Barbados in 2018 after Hurricane Maria. Its primary accreditor is CAAM-HP: currently "Accredited with Conditions" as of our last verification. "With conditions" is still CAAM-HP accreditation — do not treat it as equivalent to unaccredited.
Key facts: CAAM-HP accredited with conditions; Title IV yes; Barbados campus.

AUC School of Medicine — Sint Maarten
AUC is accredited by ACCM (not CAAM-HP). AUC has held ACCM accreditation since 1995. The current term runs to December 31, 2027.
Key facts: ACCM accredited to Dec 31, 2027; Title IV yes; Sint Maarten campus.
See AUC school page | Compare AUC pairs
Saba University — Saba (Caribbean Netherlands)
Saba is accredited by NVAO (Dutch-Flemish Accreditation Organisation) — not CAAM-HP or ACCM. The 2018 NVAO besluit ran through October 2024; a cluster peer review visit took place in November 2025 with a positive panel report in January 2026. As of our last verification, the formal NVAO renewal besluit had not been published. We hold the status as "unknown" with a custom label — confirm the latest NVAO decision at nvao.net.
Key facts: NVAO process ongoing; Title IV yes; Saba campus.

What makes the Big 4 different from other Caribbean schools?
The Big 4 are not inherently "better" — they are different in scale, track record, and accreditation history. Key differences from smaller Caribbean programs:
- Longer USMLE data — more years of pass rate reporting and published residency match statistics
- More clinical training infrastructure — larger networks of affiliated U.S. and UK teaching hospitals
- Financial aid — Title IV access means U.S. federal loans are available
- Established alumni networks — larger cohorts mean more alumni mentoring and residency connections
However, larger programs also have larger cohorts competing for residency slots. Scale cuts both ways.
Why the Big 4 are not identical
A common mistake is treating all four as equivalent alternatives. They have different:
- Accreditors — GMDC, CAAM-HP, ACCM, NVAO are separate bodies with different standards and update cycles
- Accreditation statuses — SGU CAAM-HP withdrawn, Ross with conditions, AUC ACCM accredited, Saba NVAO status in process
- Costs — published tuition varies; see each school page and the cost calculator
- Campus locations — different countries, healthcare systems, and logistical considerations
- Clinical training networks — affiliated teaching hospitals differ
