- The Clinical Case Assessment has five weighted domains; Diagnostic Findings (37%) and Sonographic Findings (30%) together make up 67%.
- The assessment uses 6 simulated clinical cases with multiple-choice and interactive image-hotspot questions.
- The outline expressly includes recognizing when POCUS cannot establish an initial diagnosis.
- The separate Peer Evaluation scores 8 evenly weighted criteria and is not part of the 100% domain total.
How the Assessment Is Built
The POCUS Musculoskeletal (MSK) Soft Tissue Certification, administered by the Point-of-Care Ultrasound Certification Academy (part of Inteleos), has two required components: a Clinical Case Assessment and a Peer Evaluation. You must pass both. This guide focuses on the first, because that is where the five content domains live.
The case assessment presents 6 simulated clinical cases. That figure is a case count, not a question count. Each scenario contains multiple-choice questions and interactive image-hotspot questions, where you click the region of an ultrasound image that answers the prompt. Delivery is online through myPOCUS and the Academy's learning management system, and the FAQ permits stopping and resuming, so there is no single timed sitting to plan around. You do have to finish both components within 90 days of purchase, and a confidentiality and nondisclosure agreement applies.
Because the five domain lines are official weighted objectives for the case assessment, they are best read as a map of what the cases are testing, not as a list of chapters. A single case may exercise views, anatomy, sonographic description and diagnosis all at once. If you are still weighing the credential itself, our overview of what MSK-ST certification is covers the basics, and the MSK-ST requirements guide explains eligibility, including the 20-case attestation and peer evaluator rules.
Domain Weights at a Glance
The weights below total 100% of the Clinical Case Assessment only. They do not describe the whole two-component credential, and the Peer Evaluation is scored separately.
| Domain | Name | Weight | What It Rewards |
|---|---|---|---|
| 1 | Standard POCUS Views | 7% | Probe placement, orientation, image acquisition |
| 2 | Anatomical Features | 22% | Identifying normal soft-tissue structures on image |
| 3 | Sonographic Findings | 30% | Describing what the image shows |
| 4 | Diagnostic Findings | 37% | Turning findings into a clinical conclusion |
| 5 | Musculoskeletal Soft Tissue Pathologies | 4% | Knowing the pathology categories in scope |
The two heaviest domains, Diagnostic Findings (37%) and Sonographic Findings (30%), account for 67% of the case assessment. That is the single most useful planning fact on the outline. If you are deciding where your hours go, begin with those two, then build the anatomy beneath them. For a sense of how this weighting translates into difficulty, see how hard the MSK-ST exam is.
Domain 4: Diagnostic Findings (37%)
This is the largest domain and the one that separates scanning from clinical reasoning. Questions here ask you to interpret what you see and arrive at a conclusion, or to recognize when you cannot.
Diagnostic Findings
Expect scenarios where an image set and brief history lead to a diagnostic decision, including the decision that POCUS is not enough.
- Distinguishing a drainable collection from diffuse soft-tissue swelling
- Separating a fluid-filled structure from a solid mass
- Recognizing when findings are indeterminate and further imaging or evaluation is needed
- Linking an image pattern to the clinical question that prompted the scan
The outline expressly includes recognizing when POCUS cannot establish an initial diagnosis. That is an unusual and important feature. Candidates trained to always commit to an answer can lose points here. A skilled soft-tissue sonographer knows the limits of the modality, and the assessment rewards that judgment.
Original teaching example
A patient presents with a tender, warm area over the forearm. The image shows thickened, hyperechoic subcutaneous tissue with a cobblestone appearance but no discrete anechoic or hypoechoic pocket. The teaching point: the finding supports cellulitis without a drainable collection, and the correct reasoning avoids calling an abscess just because the tissue looks abnormal. (This is an invented scenario for study purposes, not a live examination item.)
Domain 3: Sonographic Findings (30%)
Where Domain 4 asks "what is it," Domain 3 asks "what do you see." You are expected to describe the image in sonographic language before you diagnose it.
Sonographic Findings
Describe echogenicity, margins, internal content and behavior of tissue under the probe.
- Anechoic, hypoechoic, isoechoic and hyperechoic terminology used accurately
- Posterior acoustic enhancement versus shadowing and what each implies
- Compressibility and how tissue responds to probe pressure
- Color Doppler appearance, including whether flow is present within or around a structure
- Fluid with debris, septations or gas versus simple fluid
Note the Doppler distinction in the source material. Color Doppler is one of the eight Peer Evaluation criteria for this clinical certification, while power Doppler appears only in the specialty video-submission criteria, which do not apply to this standalone certification. Learn color Doppler well, and do not spend scarce time chasing power Doppler requirements that belong to a different pathway.
Domain 2: Anatomical Features (22%)
The third-largest domain tests whether you can identify normal anatomy on ultrasound. You cannot call something abnormal until you know what normal looks like in that location.
Anatomical Features
Recognize soft-tissue layers and adjacent structures on a still image or hotspot question.
- The layered appearance of skin, dermis, subcutaneous fat, fascia and muscle
- Muscle fiber pattern in long axis versus short axis
- Tendons and their characteristic fibrillar echotexture
- Bone cortex as a bright line with posterior shadowing
- Vessels and nerves as landmarks that orient you in the image
- Lymph nodes in their normal form, which matters for recognizing reactive nodes
Image-hotspot questions are especially relevant here. You may be asked to click on a specific structure, so passive recognition is not enough; you need to place a structure on an image yourself. Practice labeling blank images from memory rather than rereading labeled ones. Our MSK-ST study guide lays out how to build that kind of active recall into a full plan.
Domain 1: Standard POCUS Views (7%)
At 7%, this is a small slice, but it underpins everything else. Standard views are the foundation of reproducible scanning: how you hold the probe, which plane you are in, and how orientation maps to the screen.
Standard POCUS Views
Know the expected views for a soft-tissue evaluation and what a good one looks like.
- Long-axis and short-axis (transverse and longitudinal) imaging of a region of interest
- Screen orientation conventions and marker position
- Scanning a suspicious area plus a comparison view when helpful
- Recognizing a poor-quality image caused by wrong depth, gain or angle
Do not dismiss this domain because of its weight. The skills it covers (depth, gain, views) reappear as scored criteria in the Peer Evaluation, so time invested here serves both components.
Domain 5: Musculoskeletal Soft Tissue Pathologies (4%)
The smallest weighted domain names the conditions you should be able to recognize. The published pathology examples are explicitly non-exhaustive, and the scope extends well beyond the abscess and cellulitis cases most people expect.
| Category | Published Examples |
|---|---|
| Infectious / inflammatory | Abscess, cellulitis, necrotizing fasciitis, bursitis, bursopathy |
| Fluid collections | Cyst, ganglion cyst, hematoma, joint effusion |
| Masses and foreign material | Fibroma, intramuscular myxoma, foreign body |
| Muscle and nodal | Muscle tear, reactive lymph nodes |
Because Domain 5 is only 4%, it would be a mistake to memorize this list in isolation. These same conditions show up inside the Sonographic Findings and Diagnostic Findings cases, where they carry far more points. Treat the list as a set of patterns to recognize in context, not as vocabulary to recite. The MSK-ST cheat sheet condenses these pattern cues onto one page for last-minute review.
The Peer Evaluation Is Separate
The five domains describe the Clinical Case Assessment. The Peer Evaluation is a different component that assesses practical scanning ability, and it has its own eight evenly weighted criteria:
- Diagnostic Quality
- Gain
- Depth
- Views
- Measurement
- Compression
- Pathology
- Color Doppler
These eight criteria do not add to the five-domain count, and they are not percentages of the case assessment. The first two completed peer questionnaires determine the peer result, so choose evaluators who have an ultrasound clinical background and genuinely know your scanning. You need at least two. Both components must be passed, and any component you passed initially is retained for the first retake application if you fall short elsewhere.
Key Takeaway
Use the Peer Evaluation criteria as a self-audit while you practice. Compression, depth and gain are habits you can check on every scan long before your evaluators see you work. Our MSK-ST training overview discusses building those hands-on hours.
Scheduling Your Prep by Domain
Rather than a generic calendar, let the domain weights drive the order. Anatomy first, because everything depends on it; the two heavy domains next; the small ones woven in throughout.
Anatomical Features and Standard Views
- Label normal soft-tissue layers on blank images
- Practice orientation, depth and gain on live scans
Sonographic Findings
- Describe every image aloud using echogenicity and content terms
- Drill compressibility and color Doppler patterns
Diagnostic Findings and Pathologies
- Work case-style scenarios from image to conclusion
- Include cases where the correct answer is "POCUS cannot establish the diagnosis"
Mixed review
- Take a full MSK-ST practice test and review misses by domain
- Revisit the weakest of the two heavy domains
This sequence is a suggestion, not an issuer requirement; adjust it to your clinical exposure. A provider who scans abscesses weekly may compress Week 3, while someone newer to soft-tissue imaging may need longer on anatomy. Pair it with realistic expectations on pass-rate data and the passing score; neither a fixed question total, a numeric passing mark nor a credential-specific pass rate has been verified in the public sources reviewed, so be wary of any site that quotes one confidently.
Practical Notes Before You Register
Several mechanics affect how you approach the domains. The standard clinical certification fee is USD 150, with reductions for eligible countries, and POCUS Fundamentals (USD 125) is also required unless waived by a qualifying SPI examination passed within 5 years or a current qualifying ARDMS/APCA credential. When both must be purchased, the combined initial issuer fees come to USD 275, excluding optional courses. The MSK-ST certification cost breakdown walks through each line.
On retakes, there are two total content-specific attempts before a one-year waiting period, a 30-day wait follows an unsuccessful attempt, and you must apply for a retake within 90 days of failure. A retake fee applies, though its amount was not verified. Certification is valid for 5 years, and renewal involves an active-practice attestation, the relevant knowledge check and USD 50. For timing questions, see MSK-ST exam dates and scheduling, and if you are weighing the investment, whether the certification is worth it and the role-based salary guide discuss the question without promising a credential-specific pay increase.
Frequently Asked Questions
The Clinical Case Assessment has five weighted domains: Standard POCUS Views (7%), Anatomical Features (22%), Sonographic Findings (30%), Diagnostic Findings (37%) and Musculoskeletal Soft Tissue Pathologies (4%). The separate Peer Evaluation has eight criteria and does not add to that count.
Start with Anatomical Features, since normal anatomy underlies everything, then prioritize Sonographic Findings and Diagnostic Findings, which together carry 67% of the case assessment.
No. They total 100% for the Clinical Case Assessment only. The Peer Evaluation is scored separately, and both components must be passed.
No. Published pathology examples include bursitis, cyst, ganglion cyst, hematoma, foreign body, muscle tear, necrotizing fasciitis, reactive lymph nodes and more, and the list is non-exhaustive.
The content outline expressly includes recognizing when POCUS cannot establish an initial diagnosis, so identifying an inconclusive study can be the correct answer on a case.
