What This Credential Actually Is
Before sorting through requirements, it helps to be precise about which credential we mean. The OB-1T credential covered on this site is the POCUS - Obstetrics - First Trimester certification, issued through the Point-of-Care Ultrasound Certification Academy, which is part of Inteleos. It is delivered online through the Academy's myPOCUS platform and learning management system, not at a proctored testing center.
Two scoping notes matter for anyone planning their path. First, "OB-1T" is the identifier this site uses; it is not a post-nominal you append to your name. Second, this is a standalone clinical certification. It is not OB Essentials, it is not a second- or third-trimester credential, and it is not the Maternal Fetal Health specialty bundle or an RDMS OB/GYN credential. Requirements for those programs differ, so do not assume a rule you read about one applies here. If you are still orienting yourself, the explainer What Is OB-1T Certification? covers the basics.
The Four Eligibility Requirements
Qualifying comes down to four things you must have in place, plus one conditional prerequisite. Think of them as a checklist you can complete in parallel rather than strictly in sequence.
- Professional standing. You must be a healthcare professional in good standing and actively practicing in the relevant clinical area. This is a clinical credential for working practitioners, not a student or pre-clinical certificate.
- A documented case experience. You attest to performing and participating in the interpretation of at least 25 obstetrics/first-trimester POCUS cases within the preceding 2 years.
- POCUS Fundamentals. Required unless you qualify for a waiver (details below).
- Peer evaluators. You must provide at least 2 healthcare-provider peer evaluators with an ultrasound clinical background who know your relevant scanning abilities.
The 25-Case Rule: Getting the Details Right
The most commonly misread requirement is the case count. The handbook and issuer FAQ require a combination of transvaginal and transabdominal scanning within your 25 cases. That is not 25 cases of each approach; it is 25 total, and the mix must include both routes. Candidates who read "25 transvaginal and 25 transabdominal" are overestimating the burden by double.
What counts toward the 25
The wording is "performing and participating in the interpretation" of cases. That means you were hands-on with the probe and engaged in reading the findings, not simply observing a colleague scan. First-trimester cases in a typical clinical setting include confirming an early intrauterine pregnancy, evaluating a patient with bleeding or pain, and looking for ectopic pregnancy. The issuer's published pathology examples range across the same territory: early pregnancy, single and multiple intrauterine gestation, ectopic and heterotopic pregnancy, molar pregnancy, ovarian torsion, and several categories of pregnancy loss.
The 2-year lookback
Cases must fall within the preceding 2 years. Old scanning experience from earlier in your career does not carry over. If you do OB POCUS only occasionally, start logging now so the window works in your favor when you are ready to purchase.
Who tends to reach 25 quickly
Clinicians in settings with a steady stream of early-pregnancy complaints usually accumulate cases fastest. Emergency, urgent care, and women's health practice settings are natural fits. If your volume is low, plan deliberately: seek supervised scanning opportunities, and make sure you are building transvaginal experience, since that is the approach many practitioners get least exposure to.
POCUS Fundamentals: Required or Waived?
POCUS Fundamentals is a separate credential from the same issuer, and it is required for this certification unless you are exempt. The waiver conditions are specific:
| Your situation | Fundamentals required? |
|---|---|
| You passed an SPI examination within the past 5 years | Waived |
| You hold a current qualifying ARDMS or APCA credential | Waived |
| Neither of the above applies | Required (USD 125) |
Note the 5-year clock on the SPI route. An SPI pass older than 5 years does not waive the requirement. If you are unsure whether your existing credential counts as "qualifying," confirm with the issuer before you purchase, since the waiver affects your total cost. The full pricing picture is covered in OB-1T Certification Cost 2026: Complete Pricing Breakdown.
Choosing Your Peer Evaluators
The peer evaluation is unusual among certifications and is where many candidates stumble on logistics. You must supply at least 2 healthcare-provider evaluators who have an ultrasound clinical background and who know your relevant scanning abilities. A friendly colleague who has never watched you scan does not meet the spirit of the requirement.
What evaluators actually rate
The peer evaluation is a separate assessment of practical ability with 7 evenly weighted criteria:
- Diagnostic Quality
- Gain
- Depth
- Views
- Measurement
- Pathology
- M-Mode
Read that list as a preview of what a good first-trimester scan looks like in practice: optimized image settings, appropriate depth and gain, the right views, accurate measurements, recognition of pathology, and competent use of M-mode (relevant for documenting embryonic cardiac activity). Your evaluators are judging whether you do these things reliably, so choose people who have seen you do them.
The first 2 completed peer questionnaires determine the peer result. That means you want to line up evaluators who will respond promptly. A third evaluator as backup is a sensible hedge, but only the first 2 completed questionnaires count toward the outcome, so make sure your most reliable and best-informed evaluators are the ones who respond first.
Fees, the 90-Day Window, and Confidentiality
| Item | Amount / Rule |
|---|---|
| Standard clinical certification fee | USD 150 (reductions offered for eligible countries) |
| POCUS Fundamentals, when required | USD 125 |
| Combined initial issuer fees (both purchased) | USD 275, excluding optional courses |
| Completion window after purchase | 90 days for both components |
The USD 275 figure applies only when you must buy both Fundamentals and the clinical certification. If you qualify for a Fundamentals waiver, your initial issuer fee is the USD 150 clinical fee, subject to any eligible-country reduction.
Understand what the 90 days means
The 90-day period is an access and completion window, not a timed exam sitting and not a required number of course hours. Both the clinical case assessment and the peer evaluation must be completed within 90 days of purchase. The FAQ permits you to stop and resume online assessments, so you are not forced to finish in one sitting. Because peer questionnaires depend on other people's schedules, start the evaluator conversations before you buy, not after the clock starts. For scheduling specifics, see OB-1T Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
Confidentiality agreement
You will be required to agree to a confidentiality and nondisclosure agreement. Do not plan on sharing case content afterward, and treat any study resources claiming to reproduce live items with skepticism.
What You Will Face Once You Qualify
Meeting the requirements gets you to the door. It helps to know what is behind it so your preparation matches the actual assessment.
Format
The clinical component consists of 7 simulated clinical cases. That is a case count, not a question count. Each scenario contains multiple-choice questions and interactive image-hotspot questions, where you identify structures or findings directly on an image. A fixed total question count, a numeric passing mark, and a credential-specific pass rate were not verified in the public sources reviewed, so be wary of anyone quoting precise figures. Both the clinical case assessment and the peer evaluation must be passed. You can read more on this in OB-1T Passing Score 2026: Exactly What You Need to Pass and OB-1T Pass Rate 2026: What the Data Shows.
The five weighted domains
The clinical case assessment is organized around five official weighted objectives, which total 100% for that assessment only (not the whole two-component credential):
Domain 4: Diagnostic Findings (36%)
The largest slice. You are asked to reach clinically meaningful conclusions from what the images show.
- Distinguish possible pregnancy failure from definitive pregnancy failure; the issuer treats these as separate categories
- Separate complete from incomplete abortion presentations
- Recognize when findings point to ectopic or heterotopic pregnancy
Domain 3: Sonographic Findings (30%)
Describing what is actually visible before interpreting it.
- Gestational sac, yolk sac, and embryonic features
- Adnexal and free-fluid findings
- Appearance of single versus multiple intrauterine gestations
Domain 2: Anatomical Features (23%)
Recognizing normal first-trimester anatomy as a baseline for spotting abnormality.
- Uterine and adnexal landmarks
- Early gestational structures
Domain 1: Standard POCUS Views (7%)
Knowing which views to obtain and how transabdominal and transvaginal windows differ.
Domain 5: OB/First Trimester Pathologies (4%)
Small by weight, but pathology recognition also surfaces in the diagnostic and sonographic domains and in the peer evaluation's Pathology criterion.
Diagnostic Findings and Sonographic Findings together make up 66% of the clinical case assessment. If your scanning experience is broad but your interpretive reasoning is thin, those two domains are where to invest. For a deeper walk-through, see OB-1T Exam Domains 2026: Complete Guide to All 5 Content Areas.
The published pathology examples (complete abortion, definitive pregnancy failure, early pregnancy, ectopic pregnancy, heterotopic pregnancy, incomplete abortion, single and multiple intrauterine gestation, molar pregnancy, ovarian torsion, and possible pregnancy failure) are non-exhaustive, so do not treat that list as the entire syllabus.
Retakes, Validity, and Renewal
If you do not pass
The retake rules are structured, so know them before your first attempt. You get 2 total content-specific assessment attempts before a 1-year waiting period applies. After an unsuccessful attempt, a 30-day wait follows. A retake requires an application and a fee; the fee amount was not verified, so confirm it with the issuer. You must apply for the retake within 90 days of failure, and any component you already passed is retained for the first retake application. In other words, if you passed the peer evaluation but missed the case assessment, you are not forced to redo the part you already cleared. See How Hard Is the OB-1T Exam? Complete Difficulty Guide 2026 for realistic expectations.
Validity and renewal
The certification is valid for 5 years. Clinical renewal every 5 years requires an active-practice and good-standing attestation, the relevant knowledge check, and a USD 50 fee. Specialty-only professional-development points do not apply to this individual clinical certification, so ignore point-total discussions aimed at specialty programs.

A Qualification Plan Built Around the Domains
Rather than a generic schedule, sequence your preparation around the requirements and domain weights. This is the one structured plan in this article, so treat it as a template and adjust to your own case volume.
Paperwork and logistics first
- Confirm whether Fundamentals is required or waived
- Start your case log; verify you are accumulating both transvaginal and transabdominal cases
- Identify at least 2 qualified peer evaluators, plus a backup
Anatomy and views (Domains 1 and 2)
- Lock in normal first-trimester anatomy and standard views before tackling abnormality
- Practice optimizing gain and depth, since evaluators rate both
Findings and diagnosis (Domains 3 and 4)
- Spend the most time here; these two domains carry 66% of the case assessment
- Drill the possible versus definitive pregnancy failure distinction
- Work through ectopic and heterotopic reasoning
Purchase, then complete within 90 days
- Buy only when your case log and evaluators are ready
- Alert evaluators the day you purchase so questionnaires arrive early
For a fuller preparation approach, the OB-1T Study Guide 2026: How to Pass on Your First Attempt and the quick-reference OB-1T Cheat Sheet 2026: One-Page Review of Must-Know Facts pair well with scenario-based drilling. When you want to test your interpretive reasoning against case-style questions, the OB-1T practice test site is built for that, and you can start with the first trimester ultrasound practice questions to find your weak domains early.
Frequently Asked Questions
No. You need at least 25 total first-trimester cases within the preceding 2 years, and those cases must include a combination of transvaginal and transabdominal scanning. The handbook and FAQ do not require 25 of each approach.
Only if you qualify for a waiver: an SPI examination passed within the past 5 years, or a current qualifying ARDMS or APCA credential. Otherwise Fundamentals is required and costs USD 125.
At least 2 healthcare-provider peer evaluators with an ultrasound clinical background who know your relevant scanning abilities. The first 2 completed peer questionnaires determine your peer result.
You must complete both the clinical case assessment and the peer evaluation within 90 days of purchase. This is a completion window, not a timed sitting, and you may stop and resume the online assessments.
The clinical certification fee is USD 150, with reductions for eligible countries, plus USD 125 for Fundamentals when required (USD 275 combined). Clinical renewal every 5 years costs USD 50 and requires an attestation and knowledge check.
