RMSK certification is an APCA credential for eligible physicians and advanced care providers working in musculoskeletal ultrasound. Earning it requires meeting the application prerequisites and passing the MSK examination. A preparation course can support your learning; completing one does not award the RMSK credential.

How to earn RMSK certification
Confirm that your professional license meets APCA’s current eligibility criteria.
Document the required clinical ultrasound experience and arrange the required attestation.
Apply through the official certification portal with the requested documents and fees.
Prepare using the current exam outline, then schedule and pass the examination.
RMSK eligibility and clinical experience
APCA’s prerequisite document lists qualifying medical and advanced-care licenses, including PT/DPT, DC, NP and PA. Do not assume that a job title or course certificate establishes eligibility; compare your exact license with the official requirements before enrolling for exam preparation.
The clinical requirement is at least 150 musculoskeletal ultrasound studies performed and/or diagnoses authorized during the 36 months before application. These must involve actual patients in a clinical diagnostic setting, not simulated practice. The prerequisite document limits therapeutic injection or aspiration cases to 5% (8 cases).
Maintain your patient log and arrange the required third-party attestation. A course practice log is not automatically an acceptable clinical case log.

What is on the RMSK exam?
The official examination outline, version 26.1, lists four domains:
General sonographic anatomy: 20%.
General sonographic pathology: 42%.
Ultrasound-guided interventional procedures: 17%.
Instrumentation and data integration: 21%.
Use this outline to plan your study time. Pair regional anatomy review with image interpretation, and practice explaining how the scan relates to the clinical question. Review instrument settings and artifacts alongside the images rather than treating them as an isolated topic.

Build a practical RMSK study plan
Start with a baseline: identify the regions and concepts you find hardest to explain without notes.
Work region by region: review anatomy, practice a repeatable scanning approach, and compare normal appearances with relevant cases.
Keep a learning log: record what made an image difficult and the question you want to discuss with a mentor.
Use quizzes to find gaps: review the explanation behind each missed answer before repeating the question.
Revisit the official outline before choosing an exam date so your preparation covers the full scope.

Questions before you apply
Do I need CME credits to apply? APCA says CME is not required for the application, although it recommends at least 30 MSK-related CME credits. Check whether any education you choose offers the type of credit you need.
Does a weekend course satisfy the clinical requirement? Do not treat course attendance or simulated scanning as a substitute for the required clinical studies. Check the official prerequisite document and your own case records.
Is RMSK the same as RMSKS? They are separate credentials. Choose your pathway using the certifying organization’s eligibility guidance rather than assuming that similar names mean interchangeable requirements.
Where do I find fees and application dates? Use the official certification page for current application information. Confirm those details before making an exam plan.
