- OB-2/3T is the Point-of-Care Ultrasound Certification Academy's second/third-trimester obstetric POCUS certificate, delivered online through myPOCUS.
- The standard fee is $150 USD; POCUS Fundamentals is a separate $125 unless waived.
- Diagnostic Findings (36%) and Sonographic Findings (30%) together make up two-thirds of the weighted outline.
- Two components are required: a case-based knowledge assessment and a separate peer assessment with at least two evaluators.
What OB-2/3T Actually Is
OB-2/3T is shorthand for POCUS - Obstetrics Second/Third Trimester, a content-specific certificate that verifies a clinician can use point-of-care ultrasound competently in the second and third trimesters of pregnancy. It is a focused credential: rather than certifying general sonography skills, it tests whether a candidate can acquire, recognize, and interpret the bedside findings that matter in later pregnancy.
If you have seen the acronym attached to other credentials elsewhere, set those aside. This article covers only the Point-of-Care Ultrasound Certification Academy's obstetrics certificate. For naming questions specifically, see our short explainers on what OB-2/3T stands for and the OB-2/3T meaning.
Who Issues It and How It Is Delivered
The certificate is issued by the Point-of-Care Ultrasound Certification Academy, which operates as part of Inteleos. Assessment is online and issuer-operated through the myPOCUS platform, so there is no testing-center appointment to book. Candidates register, complete the required components within a defined window, and receive an Inteleos-issued digital credential through Credly when they pass.
Because the Academy sits inside Inteleos, scoring methodology is determined by Inteleos Psychometric Services together with the PCA Council. Confidentiality and nondisclosure rules apply to exam content, which is why reputable preparation focuses on concepts and image-recognition skills rather than recalled questions. For a broader orientation, our overview of OB-2/3T certification covers the credential at a higher level.
Case-Based Format: What Candidates Face
The official outline describes multiple-choice and hotspot questions that use ultrasound media, alongside a separate peer assessment. The issuer-linked Credly badge describes seven simulated clinical cases, and it is important to read that correctly: it refers to seven cases, not seven questions. Each case can contain multiple items built around the same clinical scenario.
That structure shapes how you should prepare:
- Hotspot questions ask you to click the relevant location on an ultrasound image, so you need to know where structures and abnormalities appear, not just their names.
- Multiple-choice items with media require interpreting a clip or still before choosing a diagnosis, next step, or finding.
- Case framing means clinical context matters. A finding is interpreted in light of the scenario, not in isolation.
Candidates must complete both components within 90 days of registration, and assessments can be stopped and resumed, which makes it practical to work through cases between clinical shifts.
The Five Weighted Domains
The Academy publishes a two-page content outline listing five weighted clinical-case assessment objectives. These describe what the assessment measures, not a preparation curriculum, and the weights total 100%. For a deeper walkthrough, see our complete guide to all five content areas.
| Domain | Weight | What It Emphasizes |
|---|---|---|
| Standard POCUS Views | 7% | Acquiring and recognizing the standard obstetric imaging planes |
| Anatomical Features | 23% | Identifying normal fetal, placental, and maternal structures |
| Sonographic Findings | 30% | Describing what the image shows |
| Diagnostic Findings | 36% | Translating findings into clinical conclusions |
| OB 2nd/3rd Trimester Pathologies | 4% | Abnormal conditions of later pregnancy |
Diagnostic Findings (36%) and Sonographic Findings (30%)
These two domains carry two-thirds of the weight. Sonographic Findings is about recognition and description; Diagnostic Findings is about what you conclude from it.
- Practice moving from a described image to a clinical interpretation in a single step.
- Expect abnormal presentations as well as normal ones within the case-based items.
- Pathology-based reasoning is not confined to the small pathology domain.
Anatomical Features (23%)
This domain rewards candidates who can name and locate normal structures on real images, which is also what the hotspot format tests.
- Rehearse normal anatomy until you can pick it out on a still frame quickly.
- Know what normal looks like well enough to notice deviations.
Standard POCUS Views (7%) and Pathologies (4%)
These are the smallest slices, but they are not skippable. Views underpin everything else, and the 4% pathology heading does not exclude pathology-based reasoning from the diagnostic domains, so abnormal findings can still appear throughout.
Eligibility, Peer Evaluators, and Fundamentals
The eligibility requirements are more involved than a typical knowledge test. In summary, you need:
- Active healthcare practice and good standing.
- POCUS Fundamentals, or a waiver, which can be satisfied by an SPI passed within five years or a current ARDMS/APCA credential.
- An attestation that you performed and participated in the interpretation of 25 second/third-trimester POCUS cases within the preceding two years.
- At least two peer evaluators with a clinical ultrasound background who know your content-specific imaging abilities. The first two anonymous responses are used.
The peer component is easy to underestimate. Choose evaluators who have actually watched you scan obstetric patients, brief them early, and give them time to respond so the peer assessment does not become the bottleneck inside your 90-day window.
Academy policy also requires a first content-specific certificate within three years of completing Fundamentals, except after a content-specific certificate has already been earned and maintained. If your Fundamentals date is aging, plan accordingly. Full details are in our requirements guide.
Fees and Registration Mechanics
| Item | Cost |
|---|---|
| OB-2/3T certification (standard fee) | $150 USD |
| POCUS Fundamentals (if not waived) | $125 |
| Renewal | $50 |
Reductions for eligible countries and group pricing are available, which can matter for departments certifying several clinicians together. Your total outlay depends on whether Fundamentals is waived through a qualifying credential. A full breakdown is in our certification cost guide, and the exam dates page explains scheduling given the registration-based 90-day window.
Retakes, Validity, and Renewal
Retake rules
The content-specific retake policy allows two total attempts. After a failure there is a 30-day wait, and the retake application must be submitted within 90 days of the failure. If attempts are exhausted, a one-year wait applies. Components you initially passed carry into the first retake, so a miss on one component does not erase progress on the other.
Validity and renewal
The certificate is valid for five years. Renewal requires an attestation of active practice and good standing, the relevant knowledge check, and a $50 fee, and you can begin six months before expiration. Specialty professional-development points do not apply to this renewal path.
Who Pursues It and Where It Fits
Candidates are working clinicians who already use ultrasound in obstetric settings and want documented, portable proof of competence. Because eligibility requires active healthcare practice and logged case experience, this is not an entry-level credential. Typical pursuers include physicians, advanced practice providers, midwives, and other clinicians whose practice involves later-pregnancy bedside imaging, along with emergency, labor-and-delivery, and rural or low-resource clinicians for whom a quick, reliable bedside exam changes decisions.
Employers and credentialing committees often look at certification as a way to standardize privileges for point-of-care scanning. Whether it changes pay or hiring odds depends heavily on your setting, so we avoid quoting figures here. For the practical angle, read our pages on OB-2/3T jobs, the salary guide, and whether the certification is worth it.
What OB-2/3T Is Not
Several adjacent credentials are easy to confuse with this one. OB-2/3T is not the ARDMS OB/GYN credential, not the Canadian CPoCUS 3OB, and not CP-MFH. Those carry different issuers, eligibility rules, and formats. When researching fees, dates, or requirements, confirm the source is the Point-of-Care Ultrasound Certification Academy.
Likewise, the outline's video-submission section applies only when you are enrolled in a specialty certification. It is not a third component of this standalone clinical certification. One quirk worth knowing: the outline's peer Pathology description refers to OB/First Trimester, an apparent template carryover that does not change the selected second/third-trimester scope.
Scheduling Your Preparation Around the Weights
Generic study routines matter less than aligning your time with the domain weights. A simple sequencing that follows the outline:
Views and Anatomy
- Review the standard views and normal structures, since every later domain builds on them.
- Practice locating structures on still images to mirror hotspot items.
Sonographic Findings
- Describe images systematically before naming a diagnosis.
- Work through both normal and abnormal clips.
Diagnostic Findings and Pathologies
- Spend the most time here at 36%, linking findings to clinical conclusions.
- Fold the small pathology domain into this block.
Full-Case Practice and Peer Setup
- Rehearse complete case scenarios with media.
- Confirm your peer evaluators have responded.
For a fuller plan, see the study guide, the cheat sheet, and our assessment of how hard the exam is. When you want realistic reps with media-style questions, our OB-2/3T practice tests are built for exactly that, and the training overview covers hands-on skill building.
Key Takeaway
Weight your effort toward Diagnostic Findings and Sonographic Findings, but never neglect views and anatomy. They are the foundation that makes the heavier domains answerable.
