The Short Answer: What an OB-1T Actually Is
If you searched "What is a OB-1T?", here is the direct answer: it is the site shorthand we use for the Point-of-Care Ultrasound (POCUS) Obstetrics/First Trimester Certification, an individual clinical certification for healthcare professionals who perform bedside ultrasound in early pregnancy. It verifies that you can acquire, measure, and interpret first-trimester images in real clinical scenarios, and that peers who have watched you scan can vouch for your technique.
One clarification matters up front. "OB-1T" is a retained identifier on this site. It is not an issuer-assigned exam code and it is not a post-nominal you add after your name. The credential you earn is named by the issuer as the POCUS Obstetrics/First Trimester certificate. The same acronym is used elsewhere for unrelated credentials, so make sure any source you read is describing this bedside ultrasound certification. For other angles on the same question, see our pages on what OB-1T is, what OB-1T stands for, and the OB-1T meaning.
Who Issues It and How It Is Delivered
The certification is administered by the Point-of-Care Ultrasound Certification Academy, which is part of Inteleos. Testing is delivered online through the Academy's myPOCUS portal and its learning management system, not through a walk-in testing center. Because delivery is Academy-administered and online, you can stop and resume the assessment rather than sitting through one fixed block, and you agree to a confidentiality and nondisclosure agreement before you begin.
The governing document is the POCUS Certification Academy Handbook (the issuer-hosted PDF is labeled v3 and carries no printed issue date), with the relevant material around pages 7 to 13. The scope itself comes from the issuer's one-page OB/First Trimester Content Outline, which likewise shows no printed revision date or exam version. Treat the issuer's pages as the final authority and re-check them before you purchase, since fees and policies can change.
The Two Components You Must Pass
The credential is not a single test. You need to pass both of the following:
- Clinical Case Assessment. According to the Inteleos-issued badge, this consists of 7 simulated clinical cases. That is a case count, not a question count. Within the cases you will encounter multiple-choice questions and interactive image-hotspot questions, where you click the relevant structure or finding on an ultrasound image.
- Peer Evaluation. A separate assessment of your practical scanning abilities, completed by healthcare-provider peers who know your work. The first 2 completed peer questionnaires determine the peer result.
Why the hotspot format changes how you study
Image-hotspot items reward pattern recognition over recall. It is not enough to know that a yolk sac sits inside a gestational sac; you must be able to find it on a still image, distinguish it from a fluid collection, and tell a normal early finding from a pathologic one. Practice with real or realistic images, not just flashcards of definitions. Our difficulty guide covers how candidates tend to experience this format.
Who Can Sit for It
The issuer sets several gates before you can take the assessments:
- Professional status: You must be a healthcare professional in good standing and actively practicing in the relevant clinical area.
- Case attestation: You attest to performing and participating in the interpretation of at least 25 obstetrics/first-trimester POCUS cases within the preceding 2 years.
- Scanning mix: Per the handbook and issuer FAQ, those 25 cases must include a combination of transvaginal and transabdominal scanning. This does not mean 25 cases of each approach.
- Peer evaluators: You must provide at least 2 healthcare-provider peer evaluators with an ultrasound clinical background who know your relevant scanning abilities.
- POCUS Fundamentals: Required unless waived, either by an SPI examination passed within 5 years or by a current qualifying ARDMS or APCA credential.
The practical implication: start lining up your peer evaluators early. Choose colleagues who have actually observed you scan, ideally ones with an ultrasound background, because the peer questionnaires drive half of the credential. Full details are in our OB-1T requirements guide.
What the Case Assessment Measures: Five Weighted Domains
The issuer's content outline lists five weighted objectives for the Clinical Case Assessment. These weights total 100% for that assessment only, not for the entire two-component credential, and they are the issuer's assessment objectives rather than preparation-curriculum headings.
| Domain | Weight | What It Emphasizes |
|---|---|---|
| Standard POCUS Views | 7% | Obtaining the expected views for an early pregnancy exam |
| Anatomical Features | 23% | Identifying first-trimester anatomy on images |
| Sonographic Findings | 30% | Describing what the image shows |
| Diagnostic Findings | 36% | Turning findings into a clinical conclusion |
| OB/First Trimester Pathologies | 4% | Recognizing named pathologic conditions |
Diagnostic Findings (36%) and Sonographic Findings (30%)
Together these two domains account for 66% of the Clinical Case Assessment, so they deserve the largest share of your preparation. The difference between them is the difference between observing and concluding.
- Sonographic Findings: what is visible, such as a sac, a pole, a cardiac signal, or free fluid.
- Diagnostic Findings: what those observations mean for the patient, such as early pregnancy, possible pregnancy failure, or ectopic concern.
Anatomical Features (23%)
Know the structures a clinician must recognize in the first trimester and where they appear on both transabdominal and transvaginal images.
- Uterine and adnexal landmarks
- Early gestational structures and their relationships
- How anatomy looks different across approaches
Standard POCUS Views (7%) and Pathologies (4%)
These carry the smallest weights, but they are not throwaway domains. Views underpin the practical Peer Evaluation, and pathology recognition feeds directly into Diagnostic Findings in the scenarios.
For a domain-by-domain breakdown, read our complete guide to all 5 OB-1T content areas.
The Peer Evaluation Criteria
The Peer Evaluation uses 7 evenly weighted criteria. These are separate from the five case-assessment domains and do not change the domain count:
- Diagnostic Quality
- Gain
- Depth
- Views
- Measurement
- Pathology
- M-Mode
Notice how hands-on these are. Gain and depth are knob-level skills; measurement and M-mode are the technical acts behind documenting an early pregnancy. A colleague who has watched you optimize an image and record a heart rate with M-mode can speak to these directly. If any of these feel rusty, deliberately practice them on your next several cases before your peers complete their questionnaires.
Key Takeaway
The Peer Evaluation rewards documented, observable technique. Ask your evaluators early, tell them what the 7 criteria are, and make sure at least 2 colleagues with an ultrasound background have seen your scanning firsthand.
Pathology Examples You Should Recognize
The issuer publishes a non-exhaustive list of pathology examples. Expect scenarios that touch on:
- Early pregnancy and possible pregnancy
- Single and multiple intrauterine gestation
- Ectopic pregnancy and heterotopic pregnancy
- Molar pregnancy
- Ovarian torsion
- Possible pregnancy failure and definitive pregnancy failure
- Complete abortion and incomplete abortion
Consider an original teaching scenario: a patient at an early gestational age has an intrauterine sac with no obvious embryo on the transabdominal view. The high-value reasoning is not "is it abnormal?" but "does this meet a definitive threshold, or is it a possible finding that warrants follow-up?" Practicing that distinction, and knowing when a transvaginal view would add information, is far more useful than memorizing a list of conditions. This scenario is an original teaching example, not a live exam item.
Fees, Windows, and Retakes
| Item | Detail |
|---|---|
| Standard clinical certification fee | USD 150 (reductions offered for eligible countries) |
| POCUS Fundamentals (when required) | USD 125, separate fee |
| Combined initial fees | USD 275, only when both must be purchased, excluding optional courses |
| Completion window | Both components within 90 days of purchase |
| Retake policy | 2 total attempts before a 1-year wait; 30-day wait after an unsuccessful attempt |
Two details are easy to misread. First, the 90-day period is an access and completion window, not a timed examination sitting, a practical-assessment duration, or a course-hour requirement. Second, if you need to retake, you must apply within 90 days of failure and pay a retake fee (the fee amount was not verified in the sources we reviewed). Any component you initially passed is retained for the first retake application. See our full OB-1T certification cost breakdown and the scheduling and deadlines page for planning.
A note on Fundamentals timing
POCUS Fundamentals itself does not expire. However, the Academy's policies require you to earn your first content-specific certificate within 3 years of Fundamentals, or reapply for Fundamentals. That is a progression restriction, not a 3-year expiry of the Fundamentals credential, and it stops applying once a content-specific certificate has been earned and appropriately maintained.
Validity and Renewal
The certification is valid for 5 years. Clinical renewal at the 5-year mark requires:
- An attestation of active practice and good standing
- The relevant knowledge check
- A USD 50 renewal fee
Specialty-only professional-development points do not apply to this individual clinical certification, so you do not need to chase a points total for renewal. Confirm current requirements on the issuer's maintenance page before your renewal date.
Who Benefits From It
Because eligibility requires active clinical practice and a documented case volume, the people drawn to this credential are clinicians who already scan early pregnancies at the bedside. Typical roles include:
- Emergency physicians and advanced practice providers evaluating early pregnancy complaints
- Obstetrician-gynecologists and clinicians who use point-of-care scanning in clinic
- Urgent care and family medicine clinicians who see early pregnancy concerns
- Other healthcare professionals whose practice includes first-trimester bedside ultrasound
On compensation, we stay role-based. A clinician's pay is driven by their role, setting, and employer, and we do not promise a credential-specific raise. For a grounded discussion, see our salary guide, the ROI analysis, and our overview of OB-1T-related jobs.
What This Credential Is Not
To avoid confusion with neighboring credentials, keep the scope clear. This is the standalone first-trimester clinical certification. It is not:
- OB Essentials, which uses a separate seven-question template
- A second- or third-trimester obstetrics credential
- The Maternal Fetal Health specialty bundle or a related specialty certification
- An RDMS OB/GYN registry credential
Also, the clinical video submissions shown on the shared content outline apply only when you are enrolled in a specialty certification, not to this standalone clinical certification.
A Domain-Weighted Preparation Order
Rather than a generic schedule, sequence your preparation by what the assessment weights most and what your peers will see. This is an illustrative plan, not an issuer requirement:
Views and Anatomy (7% + 23%)
- Rebuild your standard views and landmark recognition on both transabdominal and transvaginal images
- Brief your peer evaluators on the 7 criteria
Sonographic Findings (30%)
- Practice describing images precisely, including hotspot-style identification
- Drill gain, depth, measurement, and M-mode habits
Diagnostic Findings (36%) and Pathologies (4%)
- Work scenarios that force a conclusion: early pregnancy, possible versus definitive failure, ectopic, heterotopic, molar, torsion
- Take a first trimester ultrasound practice test and review every miss
Because the case assessment is image-driven, finish with timed-feeling practice in the same style. Our OB-1T study guide expands on this approach, and the one-page cheat sheet is useful for last-minute review. You can also explore training options and return to the main practice test site for question-style drills.
Frequently Asked Questions
It is this site's shorthand for the POCUS Obstetrics/First Trimester Certification from the Point-of-Care Ultrasound Certification Academy, part of Inteleos. It certifies bedside first-trimester ultrasound skills through a case assessment and a peer evaluation.
No. OB-1T is a retained site identifier, not an issuer-assigned examination code and not an awarded post-nominal. The credential you earn is the issuer's POCUS Obstetrics/First Trimester certificate.
The Clinical Case Assessment uses 7 simulated clinical cases, which is a case count rather than a question count. A fixed total number of questions was not verified in the public sources we reviewed, so we do not state one.
No. You attest to at least 25 first-trimester cases in the preceding 2 years, and those cases must include a combination of transvaginal and transabdominal scanning, not 25 of each.
It is valid for 5 years. Clinical renewal requires an active-practice and good-standing attestation, the relevant knowledge check, and a USD 50 fee. See the OB-1T certification overview for related background.
