- The C-11 trade exam itself costs $66; the separate Statutes and Rules Exam is $61 through the ROC.
- The trade exam covers 110 scored questions across 15 domains in 240 minutes, requiring 70% to pass.
- A failed attempt means a 30-day wait, extending to 90 days after a third failure - each retake adds cost.
- Bond, insurance, and application costs beyond the exam fees are separate line items tied to the license, not the test.
What You're Actually Paying For
When people search for AZ-EC certification cost, they usually expect one number. In reality, the path to holding a C-11 (CR-11) Electrical (Commercial) contractor license through the Arizona Registrar of Contractors involves several distinct fees, and the trade exam is only one of them. Understanding each piece - the trade exam fee, the statutes exam fee, and the licensing costs that sit outside the testing process entirely - helps you budget accurately instead of being surprised partway through.
This breakdown focuses specifically on the fees tied to the AZ-EC trade exam administered by PSI Services LLC on behalf of the Arizona Registrar of Contractors. If you're still deciding whether this is the right credential path, start with What Is AZ-EC? or AZ-EC Requirements 2026: Eligibility, Prerequisites & How to Qualify before diving into pricing.
The C-11 Trade Exam Fee
The C-11 (CR-11) Electrical (Commercial) trade examination costs $66. This is the exam that tests your working knowledge of commercial electrical practice specifically - not the R-11 residential outline, and not a NASCLA-style multistate exam. If you're being quoted pricing or outline details for a different track, you're looking at the wrong exam. For that $66, you get:
- 110 scored questions delivered in a computer-based, multiple-choice format
- 240 minutes to complete the exam
- A requirement to score 70% or higher to pass
- The option to test at a physical test center or via remote proctoring
PSI may also insert 5 to 10 unscored experimental questions into your exam without extending your time. These questions are indistinguishable from scored items, which is one more reason to treat every question on the screen as if it counts. For a full breakdown of how the 15 content domains are weighted within those 110 questions, see AZ-EC Exam Domains 2026: Complete Guide to All 15 Content Areas.
Where the Scored Items Concentrate
PSI's published item allocation shows three domains tied for the largest share of the exam, at 13 items apiece: Service Feeders and Branch Circuits, Grounding and Bonding, and Special Occupancies and Equipment. Together these three domains account for 39 of the 110 scored questions - over a third of your exam.
- Service Feeders and Branch Circuits - 13 items
- Grounding and Bonding - 13 items
- Special Occupancies and Equipment - 13 items
- General Electrical Knowledge - 5 items
- Conductors and Cables - 12 items
Because your $66 buys you one attempt at a fixed set of content, spending prep time proportional to these weights is the most cost-efficient way to avoid paying twice. If you want a domain-by-domain study plan tied to these weights, AZ-EC Study Guide 2026: How to Pass on Your First Attempt walks through it in detail.
Statutes and Rules Exam Cost
Separate from the trade exam, applicants also complete a Statutes and Rules Exam through the ROC's online process. This exam costs $61 and is administered directly through the Registrar of Contractors rather than through PSI's trade exam bulletin. It's a distinct fee and a distinct test - don't assume the $66 trade exam fee covers it, and don't assume passing one satisfies the other.
Together, the trade exam and statutes exam represent the core testing costs a qualifying party will pay before moving into the licensing application itself.
Key Takeaway
Budget for two separate exam fees - $66 for the C-11 trade exam and $61 for the Statutes and Rules Exam - not one combined fee.
Application, Bond, Insurance and Background Costs
Passing both exams is a prerequisite, not the finish line. To actually hold a C-11 (CR-11) Electrical (Commercial) license, the Arizona Registrar of Contractors also requires:
- A completed contractor license application for the business entity
- A background check on the qualifying party and/or principals
- A contractor's bond, which must be maintained for the license to remain active
- Proof of insurance meeting ROC standards
- Documentation of the qualifying party's experience - typically four years of practical or management trade experience, with at least two years falling within the preceding ten years, though qualifying education or manufacturer training can offset up to two years of that requirement
These items each carry their own costs (bond premiums, insurance premiums, application processing) set by the ROC and third-party providers rather than by the exam itself. Because exact bond and insurance pricing depends on your business structure, coverage amount, and provider, treat the $66 and $61 exam fees as the testing baseline and add these licensing costs on top when building your total budget. For a full walkthrough of the experience and documentation requirements, see AZ-EC Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Retake Fees and Waiting Periods
If you don't pass on your first attempt, you'll need to pay the $66 trade exam fee again to retest - there's no discounted retake rate. Beyond the repeated cost, Arizona enforces mandatory waiting periods between attempts:
- 30 days after a failed attempt before you can retest
- 90 days after your third and any subsequent failed attempt
Each failed attempt therefore costs money twice: once in the $66 re-registration fee, and once in lost time waiting to retest.

Study Materials and Prep Costs
The AZ-EC trade exam is open-book, but "open-book" doesn't mean cost-free preparation. Your approved references are:
- The 2017 National Electrical Code
- NFPA 72 National Fire Alarm Code, 2016 edition
- The specified 29 CFR 1926 OSHA reference
You'll want your own copies well before test day so you can pre-highlight, underline, annotate, and permanently tab them - all of which are allowed. What's not allowed is bringing in loose added papers or writing in the books during the exam itself, so any prep work has to be built into the books' physical structure ahead of time, not improvised at the test center. You'll also need a basic non-scientific, non-programmable calculator that meets PSI's rules; scratch paper isn't available if you choose remote proctoring, and breaks aren't permitted in that format either.
None of these material costs are set by the ROC or PSI - they're the cost of acquiring and preparing your code books, tabs, and calculator. Because the books themselves are your primary open-book resource during the 240-minute exam, treating tabbing and annotation as part of your study budget (not an afterthought the week before) pays off directly in exam-day speed.
Acquire and Tab References
- Buy the 2017 NEC, NFPA 72 (2016), and the specified 29 CFR 1926 reference
- Begin tabbing by article/section relevant to Service Feeders and Branch Circuits, Grounding and Bonding, and Special Occupancies and Equipment first, since these carry the most weight
Work Through Remaining Domains
- Extend tabbing and review to Conductors and Cables, Overcurrent Protection, and Photovoltaics
- Practice locating code references quickly under time pressure, since 240 minutes for 110 questions leaves limited time per lookup
Simulate Exam Conditions
- Run timed practice sessions using only your tabbed books and approved calculator
- Confirm test center or remote proctoring requirements, including the no-scratch-paper, no-break rule for remote sessions
For a structured week-by-week plan built around all 15 domains rather than just the top three, see AZ-EC Study Guide 2026: How to Pass on Your First Attempt. You can also run full-length timed practice questions on our practice test platform to get a feel for the pacing before spending money on an actual attempt.

Renewal Costs After Licensure
Passing the exam and getting licensed isn't the end of the cost conversation. Arizona contractor licenses, including C-11 (CR-11), operate on a two-year renewal cycle. Renewal requires filing the required paperwork, paying the renewal fee, and maintaining an active bond throughout the license period. Letting the bond lapse or missing the renewal filing can jeopardize your license status even if you never have to retake the trade exam again.
If you're evaluating whether the full cost - exams, bond, insurance, and ongoing renewal - pays off relative to the work this license opens up, Is the AZ-EC Certification Worth It? Complete ROI Analysis 2026 and AZ-EC Salary Guide 2026: Complete Earnings Analysis look at that question from the earning side.
Hidden Costs Candidates Forget
A few cost factors get overlooked because they aren't listed as line-item fees:
- Multiple attempts stack up fast. Two failed attempts at $66 each plus the mandatory waiting periods can meaningfully delay both your budget and your project timeline.
- Book editions matter. The exam references the 2017 NEC and the 2016 edition of NFPA 72 specifically. Buying a newer edition by mistake means re-purchasing the correct one before test day.
- Remote proctoring limitations. No scratch paper and no breaks during remote sessions can push some candidates toward test-center scheduling instead, which may involve its own logistics or travel cost.
- The two-year use-it-or-lose-it window. If you pass the trade exam but delay your license application past two years, you'll need to pay the $66 fee again to requalify.
Key Takeaway
Budget for at least one possible retake ($66) when planning your total cost - treating a single pass as guaranteed can leave you short if a retest becomes necessary.
Putting the Numbers in Context
At minimum, the direct testing cost to attempt licensure is $66 for the trade exam plus $61 for the Statutes and Rules Exam - $127 in combined exam fees before any bond, insurance, or application costs are added. From there, your total spend depends heavily on how many attempts you need and how quickly you move through the ROC's application requirements once you pass. Reviewing the exact scoring threshold in AZ-EC Passing Score 2026: Exactly What You Need to Pass and checking current testing availability in AZ-EC Exam Dates 2026: Testing Windows, Deadlines & Scheduling can help you avoid scheduling mistakes that add cost through delays or missed windows.
Running practice questions before you commit to a test date is one of the most direct ways to protect your $66 investment.
