- The PSI trade exam for AZ-B2 costs $66 per attempt; the separate ROC Statutes and Rules Exam (SRE) is $61.
- Failing the trade exam means a 30-day wait before retesting; a fourth attempt requires a 90-day wait, adding delay costs.
- Beyond exam fees, budget for a contractor bond, business-entity setup, background checks, and workers' compensation.
- Licenses renew on a biennial cycle requiring a renewal application, fee, and a valid bond - a recurring cost.
Total Cost Overview
When people search for the cost of the Arizona B-2 General Small Commercial Contractor Trade Exam, they usually mean one of two things: the price of sitting the PSI exam itself, or the full financial picture of becoming licensed to pull commercial permits under the $2,000,000 labor-and-materials cap. Both matter, and this breakdown covers both. Unlike open-ended certification bodies that publish vague "starting at" pricing, the Arizona Registrar of Contractors (ROC) and PSI structure works with fixed, published fees - which makes budgeting for AZ-B2 refreshingly predictable if you know where to look.
Before diving into numbers, it helps to understand exactly what you are paying for. AZ-B2 is not a certificate you print at home; it is the trade-competency exam required to qualify for a B-2 contractor license, which lets a qualifying party supervise new commercial structures or additions within the $2,000,000 threshold. If you're still unclear on what that designation actually covers, What Is AZ-B2? and AZ-B2 Meaning walk through the classification in plain language before you spend a dollar on testing.
PSI Trade Exam and SRE Fees
PSI administers the Arizona trade examination on behalf of the ROC. For the B-2 classification, one attempt at the PSI trade exam costs $66. This is a shared outline across B-1, B-2, KB-1, and KB-2 classifications, but the fee and scoring structure apply the same way regardless of which of those four you're sitting for - retain the correct commercial classification (B-2, not the residential B-1) when you register, since azb2exam.com is specifically built around the commercial small-contractor path.
Separately, applicants must pass the ROC Statutes and Rules Exam (SRE), an online course/exam that costs $61. This is not optional and not bundled with the trade exam fee - it's a distinct requirement covering Arizona licensing law rather than construction content. Together, the two mandatory exams cost $127 before any licensing fees are added.
| Exam Component | Fee | Format |
|---|---|---|
| PSI Trade Exam (B-2) | $66 per attempt | Computer-based, 100 scored questions, 240 minutes |
| ROC Statutes and Rules Exam (SRE) | $61 | Online course/exam |
| Combined mandatory testing cost | $127 | One-time (per successful pass) |
The trade exam itself is 100 scored questions across ten subject areas, with a 70% passing standard. PSI may quietly insert 5-10 unscored experimental items within the same 240-minute window, so the screen count you actually see on test day can run slightly higher than 100 - none of those extra items affect your score, but they do consume time you should plan for. For a full walkthrough of how the passing threshold is calculated, see AZ-B2 Passing Score 2026: Exactly What You Need to Pass.
Key Takeaway
Because the trade exam and the SRE are billed separately, plan to pay $127 in mandatory testing fees before you even factor in bonding or entity costs - and don't assume a "combo" discount exists.
Licensing Costs Beyond the Exams
Passing both exams doesn't hand you a license - it qualifies you to apply for one. The ROC requires a package of supporting items before the application is approved, and each carries its own cost that isn't set by PSI or the ROC's exam fee schedule:
- Contractor bond: an appropriate surety bond sized to the license classification, purchased through a bonding agent.
- Business-entity standing: costs associated with forming or maintaining the LLC, corporation, or sole proprietorship under which you'll hold the license.
- Background checks: required for the qualifying party and, depending on entity structure, other principals.
- Workers' compensation: legally required coverage that must be in place and verifiable before licensure is finalized.
None of these figures are set by PSI, so they aren't part of the "exam cost" conversation - but they're unavoidable parts of the total investment. If you're not yet sure whether you meet the experience prerequisites that let you sit for the exam in the first place, review AZ-B2 Requirements 2026: Eligibility, Prerequisites & How to Qualify before purchasing a bond you may not need yet. 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, and approved technical training can offset up to two of those four years.
Retake Costs and Waiting Periods
The single most avoidable cost in the entire AZ-B2 process is a failed attempt. Each attempt at the PSI trade exam costs $66, so a fail-and-retry cycle doubles (or triples) your testing spend fast - and the ROC imposes waiting periods that stack on top of the fee:
- A failed attempt requires a minimum 30-day wait before retesting.
- Reaching a fourth or later attempt bumps the mandatory wait to 90 days.
Those waiting periods aren't just inconvenient - they delay your ability to submit the license application, which delays bonding, which delays your ability to bid commercial work. A single retake can therefore cost far more in lost time than the $66 fee suggests. This is exactly why understanding exam difficulty and pass-rate data matters before you schedule your first sitting. How Hard Is the AZ-B2 Exam? Complete Difficulty Guide 2026 and AZ-B2 Pass Rate 2026: What the Data Shows both address this from different angles.
Where Retakes Usually Get Expensive: Concrete and Metals
Concrete carries 14 items and Metals carries 13 - the two largest domains on the 100-question outline. A candidate who under-prepares on either domain is statistically more likely to miss the 70% threshold and pay for a second $66 attempt.
- Concrete: formwork, reinforcement, curing, and placement details
- Metals: structural steel, fastening systems, and metal framing components
Hidden and Easy-to-Miss Costs
Several cost factors don't show up on a fee schedule but still affect your budget:
- Reference materials: restricted-reference open-book testing permits only the 2018 International Building Code, 2018 International Residential Code, and OSHA 29 CFR Part 1926 - other study-only titles referenced in prep materials are not allowed in the exam room, meaning you may need to purchase the permitted codebooks separately even if you already own study guides.
- Remote proctoring limitations: if you choose remote testing over an in-person test center, physical scratch paper and breaks are prohibited during the session - plan your testing environment accordingly rather than assuming a home setup will work seamlessly.
- Calculator requirements: only a basic silent, nonprinting, non-programmable, non-scientific calculator is permitted, so a phone calculator or a scientific model won't work - a small but real out-of-pocket item if you don't already own one.
- Time-off costs: the 240-minute exam window, plus travel to a test center if you don't use remote proctoring, represents real time away from paid work.
None of these are large dollar amounts individually, but stacked together they add up to more than the headline $127 in exam fees. A candidate who treats the process as "just $127" is often surprised by codebook purchases and lost billable hours.
Biennial Renewal Costs
Passing AZ-B2 and getting licensed isn't a one-time expense. Arizona contractor licenses follow a biennial renewal framework, which means every two years you'll need to submit a renewal application, pay the applicable renewal fee, and maintain a valid bond. Letting the bond lapse or missing the renewal window can jeopardize the license entirely, so this recurring cost should be treated as a standing line item in your business budget, not an afterthought.
Key Takeaway
Budget for licensure as a recurring biennial cost - renewal fee plus continuous bond coverage - not a one-time expense that ends once you pass the exam.
Cost vs. Value: Is It Worth Budgeting For
Whether $127 in exam fees plus bonding and business-entity costs is "worth it" depends entirely on what the B-2 license unlocks for your business. It's the classification that lets a qualifying party legally supervise new commercial construction or additions up to $2,000,000 in labor and materials, while specialty trades like electrical, plumbing, fire protection, air conditioning, boiler, swimming pool, spa, and water-well work still must be subcontracted to appropriately licensed contractors. That scope determines the kinds of jobs and employers open to a licensed B-2 holder. For a deeper look at how the numbers play out over a career, see Is the AZ-B2 Certification Worth It?

Budgeting Your Study Timeline
Because every failed attempt costs $66 plus a mandatory waiting period, the cheapest path through AZ-B2 is simply passing on the first try. Structuring your prep around the ten scored domains - rather than generic study advice - is the most cost-effective use of your time. The outline weights Concrete (14), Metals (13), Carpentry (12), Safety (12), Masonry (10), Thermal and Moisture Protection (10), Sitework (9), General Building Code (9), Finishes (6), and Doors and Windows (5), so your study hours should mirror those weights.
Heaviest Domains First
- Concrete (14 items) - formwork, reinforcement, curing
- Metals (13 items) - structural steel and framing
Mid-Weight Domains
- Carpentry (12 items) and Safety (12 items) - OSHA 29 CFR Part 1926 references
- Masonry (10) and Thermal/Moisture Protection (10)
Remaining Domains and Code References
- Sitework (9) and General Building Code (9) using 2018 IBC/IRC
- Finishes (6) and Doors and Windows (5)
Full Timed Practice
- Simulate the 240-minute, 100-question format
- Review restricted-reference rules and calculator restrictions before test day

You can also run full-length timed simulations on our practice test platform to see how your pacing holds up against the real 240-minute window before you pay for an actual attempt.
Keep a printable summary of the fee amounts, domain weights, and permitted references handy as you study - AZ-B2 Cheat Sheet 2026: One-Page Review of Must-Know Facts condenses exactly that. And if scheduling logistics (test centers vs. remote proctoring, blackout periods) factor into your budget planning, AZ-B2 Exam Dates 2026: Testing Windows, Deadlines & Scheduling covers the calendar side of the equation.
Once you understand every fee - $66 per trade exam attempt, $61 for the SRE, plus bonding, entity, background-check, and workers' comp costs on the licensing side, and a recurring biennial renewal fee after that - the true cost of AZ-B2 becomes a manageable, predictable business expense rather than a mystery. Running a few full-length practice exams on the practice test site before you register is one of the few ways to reduce that cost further, since it directly lowers your chance of paying for a retake.
Frequently Asked Questions
The PSI trade exam for the B-2 classification costs $66 per attempt. This fee is separate from the $61 ROC Statutes and Rules Exam (SRE), which is a distinct online requirement.
Yes. Each attempt requires its own $66 fee. A failed attempt also triggers a mandatory 30-day waiting period, and a fourth or later attempt requires a 90-day wait before you can retest.
No. The $66 PSI trade exam fee and the $61 online SRE fee are billed separately, for a combined mandatory testing cost of $127.
Licensing requires an appropriate contractor bond, business-entity standing, background checks, and legally required workers' compensation - none of which are set by PSI's exam fee schedule. Renewal every two years also requires a fee and a maintained bond.
Only the 2018 International Building Code, 2018 International Residential Code, and OSHA 29 CFR Part 1926 are permitted as restricted references in the exam room. Other study-only titles are not allowed, and additional loose papers cannot be brought in.
