REI Passing Score 2026: Exactly What You Need to Pass

What "Passing" Means for REI Certification

Candidates searching for a "passing score" usually want one number: the percentage correct, scaled score, or cut line that separates pass from fail. For Reproductive Endocrinology & Infertility, that framing needs adjustment. Subspecialty certification through the American Board of Obstetrics and Gynecology (ABOG) is not a single sitting with a single published threshold. It is a sequence: a computer-based written Qualifying Examination (QE) delivered through Pearson VUE, followed by an oral Certifying Examination (CE). Each stage has its own standard-setting logic, and "passing" means clearing both.

This article separates what is documented from what is not. Where the issuer has published a fact, we state it. Where the issuer has not published a numeric score, we say so plainly rather than invent one. If you are still orienting yourself to the credential itself, start with What Is REI Certification? and REI Requirements 2026: Eligibility, Prerequisites & How to Qualify.

Two Stages, Two Different Passing Questions

The most common planning mistake is treating REI certification as one exam. It is two distinct assessments with different formats and different skills being measured.

The common REI blueprint is a single document. It does not divide its content into separate QE and CE allocations, and it does not assign weights to either stage. That means any claim that "Domain 4 is worth X% of the written exam" is not supported by the issuer's published blueprint. Treat such claims, including practice-question allocations on any prep site, as editorial study aids rather than official weighting.

What the Common Blueprint Does and Does Not Tell You

The current ABOG REI blueprint, linked from the ABOG exam blueprints page, is a four-page document. Its URL contains 2026, but no formal revision or effective date is printed on it. What it supplies:

• Six primary categories (the domains listed below)
• 27 subcategories, from REI1.1 Hormone Structure and Function through REI6.2 Application of Genetic Screening and Testing to Patient Care
• No percentage weights
• No separate QE and CE coverage
• No cut score, scaled-score range, or number-of-questions figure

So the honest answer to "what score do I need?" is that the common blueprint does not state one, and this article will not manufacture one. Stage-specific numeric logistics, such as exam length, scoring scale, or result-reporting format, are governed by the applicable current QE or CE bulletin. Candidates should read that bulletin directly. For related mechanics, see REI Exam Dates 2026: Testing Windows, Deadlines & Scheduling and REI Certification Cost 2026: Complete Pricing Breakdown.

Pass-Rate Context From ABOG's 2026 Update

ABOG presented an update at the 2026 SMFM Program Directors Meeting that includes REI outcomes. The reported 2025 figures:

• First-time QE pass rate: 100% (N=55)
• CE pass rate: 94.7% (N=57)

Two cautions keep these numbers honest. First, the same presentation's QE repeat-taker and overall cohort counts are internally inconsistent, so no reconciled overall pass rate is asserted here. Second, small cohorts mean a single failure moves the percentage noticeably. A 100% first-time QE rate in a cohort of 55 tells you the group was well prepared, not that the written exam is trivial. REI fellows have completed a four-year obstetrics and gynecology residency and a three-year REI fellowship, per the ASRM 2025 scope-of-practice statement, so the test-taking population is highly selected.

Where Points Come From: The Six Domains

Because no weights are published, the practical strategy is breadth with depth. Every domain is fair game, and the 27 subcategories give you a concrete checklist. Here is how the domains break down, using the issuer's own subcategory labels.

Note the subcategory counts: Domain 2 and Domain 5 carry the most subcategories (five and seven respectively), which hints at breadth but is not a statement of exam weight. For a deeper walkthrough, see REI Exam Domains 2026: Complete Guide to All 6 Content Areas.

Written QE vs. Oral CE: Preparing for Each

Written Qualifying Examination

The QE rewards precise recall and interpretation. Expect to move between mechanism-level questions (receptor pharmacology, assay behavior) and applied questions (selecting a stimulation strategy, interpreting a hormone panel). Because the blueprint spans 27 subcategories without weights, the safest approach is to avoid leaving any subcategory untouched. Weak spots in "smaller-feeling" areas such as REI1.3 Laboratory Assays or REI6.1 Understanding of Genetic Testing and Screening can cost points precisely because candidates under-review them.

Oral Certifying Examination

The CE tests a different muscle: structured clinical reasoning spoken aloud. You are not selecting from options. You are presenting a differential, justifying a workup, committing to a management plan, and responding when an examiner adds a complication. Case-based topics from Domain 4 (ART techniques, treatment special considerations, fertility preservation) and Domain 5 (anatomic disorders requiring surgical judgment) lend themselves to this format, but the common blueprint does not assign domains to a stage, so avoid assuming certain topics are "written only" or "oral only."

The 2026 Eligibility Shift for Fellowship Graduates

One genuinely new development affects timing. According to the ABOG update at the 2026 SMFM Program Directors Meeting, the thesis requirement moves from CE eligibility to QE eligibility for fellowship graduates from 2026 onward. Graduates from earlier years retain their prior requirements.

Practically, a recent graduate should treat thesis completion as something to resolve before sitting for the written QE, not something that can wait until the oral stage. If you graduated before 2026, confirm which rule applies to your cohort. Eligibility details live in the current bulletin, and our summary of the broader pathway is in REI Requirements 2026: Eligibility, Prerequisites & How to Qualify. The same presentation lists historical 2026 dates of July 20 for the subspecialty QE and April 13-17 for the CE, plus continuing-certification participation to remain certified. Treat those as past reference points, not as upcoming booking promises, and check ABOG for current windows.

Sequencing Your Review Around the Blueprint

Since there is no published weighting to optimize against, sequence by dependency. Foundational content first, because it makes later domains easier to reason about.

For a fuller plan, see the REI Study Guide 2026: How to Pass on Your First Attempt and the condensed REI Cheat Sheet 2026: One-Page Review of Must-Know Facts. When you want timed, domain-tagged questions to find weak subcategories, the REI practice test lets you drill by area, and you can return to the main practice site as your review narrows. Any question allocation across domains in our practice tools is an editorial design choice, not official coverage.

How to Verify Current Numbers Before You Plan

Because this page deliberately avoids inventing a cut score, here is how to get authoritative specifics:

1. Read the current QE bulletin for written-exam logistics, scoring description, and any numeric details.
2. Read the current CE bulletin for oral exam structure and reporting.
3. Check the ABOG exam blueprints page for the latest REI PDF, since the linked document carries no printed revision date.
4. Confirm your cohort's eligibility rules, especially the thesis timing change for 2026 and later graduates.
5. Review cost and timing alongside the bulletin; our pricing breakdown and ROI analysis provide context but never replace the issuer's fee schedule.

Frequently Asked Questions

The practical conclusion is simple: there is no magic number to chase. Master all six domains and 27 subcategories, prepare differently for the written and oral stages, and confirm numeric specifics in the current ABOG bulletins before you commit to a plan.
