Abstract The Single Accreditation System (SAS) unified graduate medical education (GME) accreditation for allopathic (MD) and osteopathic (DO) programs under the Accreditation Council for Graduate Medical Education (ACGME). Implemented between 2015 and 2020, it aimed to expand access and standardize residency training across degree types. While the SAS succeeded in expanding opportunities for DO graduates in certain specialties, particularly family medicine and pathology, persistent disparities remain across competitive medical and surgical fields. Specialty-specific analyses reveal that DO applicants continue to face significant barriers in dermatology, ophthalmology, plastic surgery, neurosurgery, and orthopedic surgery, with disproportionately lower match rates and limited representation in top-tier residency programs. Structural challenges including the closure of many osteopathic-led programs, limited access to research mentorship, and degree-based bias among residency programs have exacerbated these disparities. Although Osteopathic Recognition and initiatives such as the Pathologist Pipeline have helped support osteopathic participation in select areas, broader reforms are needed to fulfill the original goals of the SAS. Enhancing academic partnerships, expanding research infrastructure, addressing implicit biases, and fostering DO leadership within academic medicine are critical steps toward ensuring equitable residency access for all graduates. Continued monitoring of match trends and specialty-specific outcomes will be essential to assessing the SAS’s long-term impact on healthcare workforce diversity and equity.

A 90-day district inquiry

1. Days 1–15 · Appraise. Read the source methods, recruitment, comparator, outcomes and limitations. Record how the study setting differs from your district and which claim the design can support.
2. Days 16–30 · Design. Choose one school improvement question with teachers. Protect a short shared planning cycle, agree an instructional change and use a common rubric for examining student work. Agree participation, privacy protections, baseline and stopping rules before starting.
3. Days 31–60 · Observe. Collect the pre-agreed measures, keep a log of implementation changes and invite confidential voluntary feedback. Preserve existing support for staff and learners.
4. Days 61–90 · Decide. Review implementation fidelity, teacher time and independently scored student work against a recorded baseline. Examine access differences and competing explanations before attributing changes to leadership. Make a dated decision to stop, revise or extend the inquiry.

Board decision brief

Present the local problem, source setting, evidence limits, intervention, responsible owner, total cost, measured changes and uncertainty. Separate staff perceptions, implementation measures and student learning outcomes.
