- FAQ
- ICC does not publish a public numeric pass rate for exam ID 21; treat any specific percentage you see elsewhere as unverified.
- Passing requires a scaled score of 75, not 75% of questions correct - the two are not the same thing.
- The exam has 80 four-option multiple-choice questions in a 150-minute window.
- ICC's January 12, 2026 availability list still lists both the 2021 and 2024 versions - align your study materials with the version you actually schedule.
What ICC Actually Publishes About Pass Rates
If you searched for "AIPE pass rate 2026" hoping for a clean percentage, here's the honest answer: the International Code Council does not release a public pass-rate figure for the Accessibility Inspector/Plans Examiner exam (official exam ID 21). ICC's publicly available documentation - the exam content outline, the admin rules, and the renewal bulletin - focuses on eligibility, scoring mechanics, and exam logistics rather than pass/fail statistics broken out by credential.
That absence of a number is actually useful information in itself. It means you shouldn't plan your preparation around a rumored percentage from a forum post or a different certification that happens to share the "AIPE" acronym. Several other credentials use that same abbreviation, and pass-rate figures floating around online sometimes belong to those unrelated programs. For the ICC accessibility credential specifically, the smarter approach is to study the scoring mechanics ICC does disclose and treat the exam as a scaled-score threshold challenge, not a percentile guessing game.
How the Scaled Score of 75 Works
The single most misunderstood fact about this exam is the passing standard. ICC requires a scaled score of 75 to pass - this is not the same as answering 75% of the 80 questions correctly. Scaled scoring converts your raw number of correct answers into a standardized score using a psychometric formula that accounts for question difficulty. That means two candidates who each miss the same raw number of questions could theoretically land on different sides of the passing line depending on which specific questions they missed.
Practically, this has one big implication for your prep: you cannot reliably back into "how many questions I can afford to miss." Instead, aim to build broad, even competence across all ten content domains rather than acing a few favorite topics while guessing on others. For a full breakdown of exactly what the scaled score means and how ICC frames it, see our dedicated AIPE Passing Score 2026 guide.
Key Takeaway
Don't chase a target raw-score percentage. Study for even, cross-domain competence, since the scaled-score conversion rewards consistency over lopsided strength in one or two domains.
Exam Format: 80 Questions, 150 Minutes
The exam itself is 80 four-option multiple-choice questions administered in a 150-minute window - that works out to roughly 1 minute 52 seconds per question if you spread time evenly, though most candidates move faster on straightforward code-lookup items and slower on scenario-based ones. ICC's PRONTO delivery system supports both live remote proctoring and in-person proctoring at participating Meazure Learning test centers, so you can choose whichever format fits your schedule and comfort level.
Because this is an open-book style exam under ICC's approved-reference rules, pacing is partly a function of how efficiently you can navigate your references. ICC allows bound print references with permanent tabs and permitted annotations, plus a basic nonprogrammable, nonprinting calculator. Candidates who tab their 2024 International Building Code, 2024 International Existing Building Code, and ICC A117.1-2017 by topic - rather than relying purely on memory - tend to move through the 80 questions with far less time pressure.
Which Domains Drive the Most Missed Questions
ICC's exam content outline for this credential is organized into ten domains that mirror the official 2024 study-guide objectives. While there's no published per-domain miss-rate data, the domains that tend to demand the most careful reading - because they involve dimensional criteria, multiple overlapping code references, or room-specific exceptions - are worth extra attention:
Domain 3: Accessibility Routes
Covers accessible route continuity, slope and cross-slope thresholds, changes in level, and clear width requirements. This domain frequently overlaps with site and building element questions, so candidates must track which code section governs a given transition.
- Distinguish accessible route requirements from general circulation path requirements
- Know when exceptions apply to existing buildings under the IEBC
Domain 5: Plumbing Elements and Facilities
Tests knowledge of clearances, grab bar placement, lavatory and water closet dimensions, and fixture counts as they relate to accessibility rather than general plumbing code.
- Memorize clear floor space dimensions for common fixtures
- Cross-reference A117.1-2017 figures rather than relying on text alone
Domain 9: Dwellings and Sleeping Units
Focuses on Type A and Type B dwelling unit requirements, accessible and adaptable features, and how scoping differs between multifamily housing and transient lodging.
- Know the scoping tables tying unit counts to required accessible units
- Understand adaptability provisions versus full accessibility requirements
For the complete list of all ten domains with detailed learning objectives, the AIPE Exam Domains 2026 complete guide breaks down every content area, including General Administrative and Scoping Provisions, Building Blocks, General Site and Building Elements, Communication Elements, Special Rooms and Spaces, Built-in Furnishings and Equipment, and Recreational Facilities.
The 2024 Code Cycle Factor
One variable that has a real, documented effect on exam difficulty and preparation accuracy is code cycle alignment. This exam is currently offered referencing the 2024 International Building Code, the 2024 International Existing Building Code, and ICC A117.1-2017. If you study from outdated code editions or generic accessibility guides that don't map to this specific cycle, you risk learning provisions that have since been renumbered, revised, or replaced.
This is precisely why generic "accessibility exam prep" content is risky. A resource that doesn't specify code edition alignment could be teaching you 2018 or 2021 cycle language when your actual exam draws from 2024-cycle documents. Always confirm which edition a study resource references before trusting it.
2021 vs. 2024 Exam Version: Why It Matters
ICC's January 12, 2026 availability list includes both the 2021 and 2024 exam versions for this credential. That dual availability is a detail candidates frequently overlook - and it directly affects how you should prepare.
| Factor | 2021 Version | 2024 Version |
|---|---|---|
| Primary code references | Earlier IBC/IEBC editions and applicable A117.1 edition | 2024 IBC, 2024 IEBC, ICC A117.1-2017 |
| Study guide alignment | Older study guide editions may not match | Matches ICC's current official online study guide |
| Availability as of Jan 12, 2026 | Listed as available | Listed as available |
| Recommended for new candidates | Only if scheduling requires it | Generally preferred for current code alignment |
Before you buy any practice material or the official study guide, confirm which version you're registering for. Mixing 2021-cycle notes with a 2024-version exam attempt (or vice versa) is a preventable way to lose points on code-specific questions.
A Domain-Weighted Prep Plan
Generic study techniques like spaced repetition or timed practice blocks only help if they're applied to the right material at the right time. Here's a compact four-week structure built around this exam's ten domains rather than a one-size-fits-all template.
Foundations and Scoping
- Domain 1 (General Administrative and Scoping Provisions) and Domain 2 (Building Blocks)
- Tab your 2024 IBC and A117.1-2017 by chapter for quick lookup
Routes, Site, and Plumbing
- Domain 3 (Accessibility Routes), Domain 4 (General Site and Building Elements), Domain 5 (Plumbing Elements and Facilities)
- Practice open-book lookups under timed conditions to build speed with permitted references
Communication, Rooms, and Furnishings
- Domain 6 (Communication Elements), Domain 7 (Special Rooms and Spaces), Domain 8 (Built-in Furnishings and Equipment)
- Review IEBC-specific exceptions for existing building scenarios
Dwellings, Recreation, and Full Review
- Domain 9 (Dwellings and Sleeping Units), Domain 10 (Recreational Facilities)
- Run full-length, 80-question timed practice sessions to simulate the 150-minute limit
