AZ-B2 Pass Rate 2026: What the Data Shows

What the Published Data Actually Shows

Anyone searching for an "AZ-B2 pass rate" quickly runs into a wall: neither the Arizona Registrar of Contractors (ROC) nor PSI, the vendor that administers the Arizona trade examination, publishes a public pass-rate percentage for the B-2 General Small Commercial Contractor trade exam. This is worth stating plainly because a lot of exam-prep content online recycles numbers that don't belong to this credential at all. If you want the real picture, the honest answer is that the official bulletin and outline give you structural data - question counts, domain weights, timing, and retake rules - rather than a pass/fail statistic.

That structural data is actually more useful than a single percentage would be. It tells you exactly how the 100 scored questions are distributed, how much time you have, and what happens if you don't clear the bar on your first try. This article walks through that data point by point, using only what's in the current outline (effective May 9, 2024) and the general Arizona PSI bulletin (dated February 18, 2026).

The 70% Passing Standard, By the Numbers

The scored outline contains 100 questions delivered over 240 minutes, with a 70% passing standard. In plain terms, that means 70 correct answers out of the 100 scored items clears the exam. That's the entire mathematical story behind "passing" - no curve, no domain-by-domain minimum, just a single overall threshold applied across all 10 content areas.

Because there's no sub-score requirement, a candidate who is strong in Carpentry and Safety but weaker in, say, Doors and Windows can still pass by making up the difference elsewhere. That flexibility matters when you're deciding where to spend your limited study hours. For a full breakdown of exactly how the scoring threshold works and what it means for borderline scores, see AZ-B2 Passing Score 2026: Exactly What You Need to Pass.

Domain Weighting: Where the Points Live

The single most useful piece of "pass rate" data available isn't a percentage - it's the official item allocation across the 10 domains. Every one of the 100 scored questions falls into one of these categories, and the counts are fixed by the outline:

Concrete is the largest domain, followed by Metals - together they account for 27 of the 100 scored items, more than a quarter of the entire exam. Doors and Windows, by contrast, is the smallest at just 5 items. If you're deciding where a wrong guess costs you the most opportunity, it's in the mid-size and large domains, not the small ones.

For a domain-by-domain breakdown of what each of the 10 content areas actually tests - not just the item counts, but the topics and question styles inside each one - see AZ-B2 Exam Domains 2026: Complete Guide to All 10 Content Areas.

Retake Rules and What They Reveal

The retake structure is another piece of hard data that tells you something about how the state expects candidates to approach this exam. If you fail, you must wait 30 days before retesting. If you reach a fourth attempt or beyond, the wait extends to 90 days. That step-up is a strong signal: Arizona expects candidates who fail multiple times to actually change their preparation, not just retake the same test on the same material a week later.

There's no public data on how many candidates need a second or third attempt for the B-2 trade exam specifically, but the tiered wait-time structure by itself is useful planning information - especially if you're trying to hit a licensing deadline. Combine that with the fact that you must apply within two years of passing, and it becomes clear why timing your first attempt carefully matters more than trying to "get a feel for it" on attempt one.

Scored vs. Unscored Questions

One detail that quietly affects how the exam "feels" is that PSI may add 5-10 unscored experimental questions within the same 240-minute session. These items are mixed in with the 100 scored questions but don't count toward your result - and you won't know which ones they are while testing.

This matters for pass-rate discussions because it means the exam screen you sit for isn't a fixed, guaranteed count. The scored base is always 100 questions at the 70% standard, but the total number of items you actually answer during your session can run higher. Don't assume you're behind pace if the question count feels larger than 100 - that's expected behavior under this outline, not a sign something went wrong.

Cost and Timeline Data

Beyond scoring mechanics, the other numbers worth tracking are the cost and timing figures tied to actually sitting for this exam:

• One PSI trade-examination attempt costs $66.
• The separate online ROC Statutes and Rules Exam/course (SRE) costs $61 and must be completed before you submit your license application.
• Testing runs 240 minutes and is available at PSI test centers or through remote proctoring.
• The qualifying party typically needs four years of relevant practical or management experience, with at least two of those years falling within the preceding ten; approved technical training can offset up to two years of that requirement.

Who Actually Sits for the AZ-B2 Exam

The B-2 classification is built for contractors and qualifying parties working on new commercial structures or additions where total labor and materials fall at or below $2,000,000. That scope shapes who ends up testing: superintendents, project managers, and owner-qualifiers moving from residential or subcontractor roles into general commercial work under a capped project size.

Because electrical, plumbing, fire protection, air conditioning, boiler, swimming pool, spa, and water-well work must all be subcontracted to appropriately licensed specialty contractors, the exam itself stays focused on structural and building-envelope trades - sitework, concrete, masonry, metals, carpentry, thermal/moisture protection, doors/windows, finishes, safety, and general building code. That's a meaningfully different scope than a residential-only license, and it's part of why generic contractor exam content doesn't map cleanly onto this outline.

Turning the Data Into a Study Plan

Once you accept that there's no public pass-rate percentage to chase, the smarter move is to let the domain-weighting data drive your schedule directly. A short block-based approach - focused sessions on one domain at a time, with heavier domains getting more repetitions - works well against this specific outline because the item counts are fixed and known in advance.

Remember that the exam is restricted-reference open-book: the 2018 International Building Code, 2018 International Residential Code, and OSHA 29 CFR Part 1926 are permitted in the testing room, and pre-existing highlighting, underlining, annotations, and permanent tabs are allowed. Loose papers and in-test writing are not. Building familiarity with your own tabbed references during study is part of preparing for this specific exam, not a generic tip. For a deeper walkthrough of study sequencing built around these domains, see AZ-B2 Study Guide 2026: How to Pass on Your First Attempt, and if you're still gauging overall difficulty before committing to a timeline, read How Hard Is the AZ-B2 Exam? Complete Difficulty Guide 2026. You can also run full-length timed sets on the practice test platform to get a feel for the 100-question, 240-minute pacing before exam day.

Practicing against realistic question sets on azb2exam.com's practice tests is one of the few ways to simulate the pacing data above without waiting for exam day itself. Working through timed sets by domain - rather than random mixed quizzes - mirrors how the real outline is structured and helps you notice, in advance, which of the 10 domains needs another pass.
