- OB-2/3T is the POCUS Certification Academy's second/third-trimester obstetric certificate, administered online through myPOCUS under Inteleos.
- The standard fee is $150 USD; POCUS Fundamentals costs a separate $125 unless waived.
- Candidates attest to 25 second/third-trimester POCUS cases within two years and supply at least two peer evaluators.
- Diagnostic Findings (36%) and Sonographic Findings (30%) together make up two-thirds of the weighted content outline.
What the OB-2/3T Certificate Actually Is
OB-2/3T is shorthand for the Point-of-Care Ultrasound (POCUS) Obstetrics Second/Third Trimester certificate. It is a content-specific credential that verifies a clinician can acquire, recognize and interpret focused obstetric ultrasound findings in the second and third trimesters. It is not a general sonography registry, and it does not certify a full diagnostic obstetric ultrasound practice. It certifies point-of-care competence: the bedside, question-driven use of ultrasound by a clinician who is already practicing.
If you are comparing the many pages that define this term, you may also want our shorter explainers, including What Is OB-2/3T?, What Does OB-2/3T Stand For? and OB-2/3T Meaning. This article goes deeper into how the certification works end to end.
Who Issues It and How It Is Delivered
The certificate is offered by the Point-of-Care Ultrasound Certification Academy, which is part of Inteleos. Delivery is issuer-operated and online through the myPOCUS platform. You do not travel to a testing center; you complete the assessment through the issuer's own system.
Several delivery details matter for planning:
- Two components. The clinical assessment and a separate peer assessment. Both must be completed within 90 days of registration.
- Stop and resume. Assessments can be paused and picked up later, which makes the 90-day window easier to manage around clinical shifts.
- Confidentiality. Confidentiality and NDA rules apply, so item content cannot be shared or reproduced.
- Scoring. The scoring methodology is determined by Inteleos Psychometric Services and the PCA Council. To earn the certificate you must pass all required assessment components.
The issuer's public materials do not publish an assessment-wide question total, a fixed examination timer, a numerical passing mark or a credential-specific pass rate. Be skeptical of any site that quotes precise figures for these. We discuss what is and is not known in OB-2/3T Passing Score 2026 and OB-2/3T Pass Rate 2026.
Eligibility: Who Can Sit for It
OB-2/3T is gated by practice experience, not just a fee. To qualify you generally need to meet all of the following:
- Active healthcare practice and good standing.
- POCUS Fundamentals passed within the past five years, or a waiver for it. Qualifying waivers include an SPI passed within five years or a current ARDMS or APCA credential.
- 25 second/third-trimester POCUS cases. You attest that you performed, and participated in the interpretation of, 25 such cases within the preceding two years.
- At least two peer evaluators with a clinical ultrasound background who know your content-specific imaging abilities.
There is also an Academy policy requiring a first content-specific certificate within three years of completing Fundamentals, except where a content-specific certificate has already been earned and maintained. If you are planning around dates, confirm your own Fundamentals timeline early. For a fuller walk-through, see OB-2/3T Requirements 2026: Eligibility, Prerequisites & How to Qualify.
The Peer Assessment Component
Many certifications rely solely on a knowledge exam. OB-2/3T adds a separate peer assessment. You provide the contact details of at least two peer evaluators who understand your clinical ultrasound abilities in this content area. The first two anonymous responses received are the ones used.
Practical implications:
- Choose evaluators who have actually watched you scan or reviewed your obstetric images, not simply colleagues who like you.
- Brief them on timing so the responses arrive well inside your 90-day completion window.
- Because only the first two anonymous responses count, avoid naming evaluators you suspect will be slow to reply.
The content outline also contains a video-submission section, but that applies only when you are enrolled in a specialty certification. It is not a third component of this standalone clinical certificate.
Question Style and Case Format
The official outline specifies multiple-choice and hotspot questions that use ultrasound media. Hotspot items ask you to click the relevant region of an image or clip, which tests whether you can actually localize a structure or finding rather than merely name it.
The Inteleos-issued Credly badge describes seven simulated clinical cases. Note the wording: seven cases, not seven questions. Each case is a clinical scenario with associated imaging and a set of items attached to it. The issuer's FAQ offers planning guidance of roughly 20 to 30 minutes per case, but this is guidance for scheduling your effort, not a fixed examination timer.
Key Takeaway
Prepare for case-based reasoning, not isolated recall. A typical case asks you to recognize the view, identify the anatomy, describe what you see, and reach a clinical conclusion. Practice moving through that chain in one sitting. Our difficulty guide explains where candidates tend to feel pressure.
The Five Weighted Domains
The five domain lines come from the issuer-linked, undated two-page Obstetrics 2nd/3rd Trimester Certification Content Outline. They are the weighted assessment objectives for clinical cases, not a preparation curriculum, and the weights total 100%.
| Domain | Weight | What It Emphasizes |
|---|---|---|
| Standard POCUS Views | 7% | Obtaining and recognizing the standard obstetric views |
| Anatomical Features | 23% | Identifying normal second/third-trimester anatomy |
| Sonographic Findings | 30% | Describing what the image shows |
| Diagnostic Findings | 36% | Turning findings into clinical interpretation |
| OB 2nd/3rd Trimester Pathologies | 4% | Pathology heading within the outline |
Diagnostic Findings (36%)
The largest domain. It rewards candidates who can move from an image to a clinical conclusion, such as recognizing presentation, placental location, fluid status or a concerning abnormality and understanding what it implies at the bedside.
- Practice interpreting a finding, not just naming it
- Link each sonographic observation to a clinical decision
Sonographic Findings (30%)
The second-largest domain. Expect to describe what is visible, including echogenicity, structure appearance and relationships between structures, using correct sonographic vocabulary.
- Rehearse precise descriptive language
- Compare normal and abnormal appearances side by side
Anatomical Features (23%)
Recognition of normal anatomy across the second and third trimesters. This is the foundation that makes the two larger domains answerable.
Standard POCUS Views (7%) and OB 2nd/3rd Trimester Pathologies (4%)
The two smallest domains by weight. Do not neglect them, but do not over-invest either. One important caveat: the 4% pathology heading does not exclude pathology-based reasoning from the diagnostic domains, so abnormal findings will still appear elsewhere in cases.
Because the outline reuses some template language from another certificate (its peer Pathology description refers to OB/First Trimester), treat that line as a carryover that does not change the selected scope. For a deeper breakdown, see OB-2/3T Exam Domains 2026: Complete Guide to All 5 Content Areas.
Fees and Registration Mechanics
| Item | Amount | Notes |
|---|---|---|
| OB-2/3T standard fee | $150 USD | Eligible-country reductions and group pricing are available |
| POCUS Fundamentals | $125 USD | Separate fee unless waived |
| Renewal | $50 | Plus attestation and the relevant knowledge check |
The practical sequence is: confirm Fundamentals or a waiver, document your 25 cases, line up peer evaluators, register through myPOCUS, then complete both components inside the 90-day window. Fees and policies can change, so verify against the issuer's current pages before paying. Our OB-2/3T Certification Cost 2026 article itemizes the full budget, and OB-2/3T Exam Dates 2026 covers scheduling.
Retakes, Validity and Renewal
Retake Policy
The content-specific retake rules are structured and worth knowing before you register.
- Two total attempts are allowed.
- A 30-day wait applies before a retake.
- You must apply for the retake within 90 days of the failed attempt.
- If attempts are exhausted, a one-year wait applies.
- Components you initially passed carry into the first retake.
Validity and Renewal
The certificate is valid for five years. Renewal requires an active-practice and good-standing attestation, the relevant knowledge check and a $50 fee. Renewal can begin six months before expiration. Specialty professional-development points do not apply to this renewal.
Who Benefits From the Credential
Because it certifies bedside obstetric ultrasound, the certificate is most relevant to clinicians who already scan pregnant patients as part of their work. That commonly includes emergency physicians and advanced practice providers handling obstetric presentations, obstetricians and midwives who use ultrasound in clinic or labor settings, family medicine and rural clinicians with limited access to formal imaging, and hospitalists or critical care providers who encounter pregnant patients.
Employers value documented competence, but the credential does not set pay on its own, and we do not quote salary figures here because the issuer publishes none. For a measured look at the career side, read OB-2/3T Jobs, the OB-2/3T Salary Guide and Is the OB-2/3T Certification Worth It?
Sequencing Your Preparation by Domain
You do not need a generic study system; you need an order that follows the weights. One sensible arrangement:
Views and Anatomy
- Standard POCUS Views (7%) and Anatomical Features (23%) first, since later domains depend on them
- Build fluency recognizing normal second/third-trimester anatomy
Sonographic Findings
- Spend extra time here (30%) on describing images accurately
- Practice hotspot-style localization on clips
Diagnostic Findings and Pathology
- Devote the most hours to the 36% domain
- Work full case-style sets, including abnormal findings
Finish by running timed, multi-item cases using the 20 to 30 minutes per case planning figure as a pacing reference. Our OB-2/3T Study Guide 2026 expands this into a full plan, and the OB-2/3T Cheat Sheet condenses the must-know facts. For realistic case-style questions, use the OB-2/3T practice tests.
Avoiding Confusion With Similar Credentials
Search results for "OB-2/3T" can be messy because obstetric ultrasound has several credentialing routes. To stay on the right track:
- Confirm the issuer is the Point-of-Care Ultrasound Certification Academy (Inteleos) and the platform is myPOCUS.
- Ignore any figure that cannot be traced to the issuer's own pages, particularly pass rates and passing scores, which are not publicly verified for this credential.
- Do not apply requirements, fees or formats from the ARDMS OB/GYN pathway, Canadian CPoCUS 3OB or CP-MFH to this certificate.
