The Arizona Contractor License Exams
Updated 2026-09-28
Arizona splits its testing between two providers. The Registrar of Contractors runs the Statutes and Rules Exam (SRE) as an online course, and PSI Services delivers the trade exams, either at a test center or through remote proctoring. Which trade exam you take, if any, depends on the classification, and the ROC's form RC-L-206B spells that out.
This guide covers registration, fees, the rules at PSI, and what the published content outlines say about three common trade tests. It is based on PSI's Arizona candidate bulletin dated February 18, 2026 and the outlines linked from it.
The SRE: a course, not a proctored test
Unlike the business-law tests in most neighboring states, Arizona's SRE is a computer-based course that the ROC provides and maintains. You work through Arizona's contracting statutes and ROC rules and are tested on the material as you complete it. PSI's bulletin gives the price as $61 and says it is available only online.
The statute behind it, section 32-1122(E)(2), says the written exam should show general knowledge of Arizona's building, safety, health and lien laws, the administrative principles of running a contracting business, and the registrar's rules. That is the scope to study, even though the format is a course. Qualifying parties who held that role on an Arizona license within the last five years do not need to repeat it.
Registering for a PSI trade exam
Once you are eligible, PSI emails you a link to create an account and book. You choose a test center or remote proctoring. Arizona centers listed in the bulletin are in Flagstaff, Glendale, Phoenix, Tempe and Tucson, and the exam can also be taken at PSI centers in other states. Phone booking is at (855) 744-0310.
PSI's fee table is $66 for one examination, $116 for two, and $40 for the solar portion alone. The same fee applies to a first attempt or a retake, it is not refundable or transferable, and a paid fee stays valid for one year. Candidates with approved ADA accommodations must book by phone with a PSI registrar.
Retakes, cancellations and missed appointments
After a failed attempt you must wait 30 days to retest. You get three attempts at each exam; after the third failure there is a 90-day wait before the next try. You cannot book a new appointment the same day you test.
To cancel or reschedule without losing the fee, PSI must receive notice two days ahead, so a Monday exam must be cancelled by the previous Saturday. Voicemail and email do not count. You forfeit the fee by not showing, arriving after the start time, or lacking acceptable ID. For a remote exam, not launching within 15 minutes after the booked time forfeits the fee.
Open book, with strict rules about your books
Arizona's trade exams are open book for the references each outline marks as allowed, and you bring your own copies. You may highlight, underline, annotate and tab them before the exam, but only with permanent tabs that would tear the page if pulled; sticky notes must come out before you start. Writing or highlighting during the exam gets reported to the ROC. Printouts are allowed if bound, spiral or in a binder, and no loose papers may come in with them.
Code questions are based only on the code edition the outline lists, while answers on other references may follow later editions. PSI's bulletin also sets a tiebreak rule: a code, law or regulation overrides other references, and a state requirement overrides a national one. A silent, non-printing, non-programmable calculator is allowed. At a center you get scratch paper and a pencil; remote candidates get no scratch paper and no breaks.
What three trade outlines look like
Each outline gives the question count, time limit, passing score and items per subject. Three common ones:
- B General Residential (shared with B-3 and CR-61): 100 questions, 240 minutes, 70 percent to pass. Sitework, concrete and carpentry are 17 items each, thermal and moisture protection 12, masonry and finishes 9 each, doors and windows 7, metal framing and safety 6 each. The 2018 IRC and 29 CFR 1926 are allowed in the room.
- B-1 and B-2 commercial (shared with KB-1 and KB-2): 100 questions, 240 minutes, 70 percent. Concrete 14, metals 13, carpentry and safety 12 each, masonry and thermal and moisture protection 10 each, sitework and general building code 9 each, finishes 6, doors and windows 5. The 2018 IBC and IRC and 29 CFR 1926 are allowed. B-1 and B-2 applicants may take the NASCLA Accredited Examination for Commercial General Building Contractors instead.
- CR-37 Plumbing (Commercial): 100 questions, 240 minutes, 70 percent. Drainage, waste and vents lead at 15 items, followed by water supply at 12, fuel gas and septic and sewer at 11 each, and general knowledge at 8. Allowed references include the 2018 International Plumbing, Fuel Gas and Mechanical Codes and NFPA 13, 13D and 13R.
During and after the exam
A tutorial of up to 15 minutes runs before the timed exam and is not counted against it. Expect 5 to 10 unscored experimental questions beyond the outline count; they do use your time. You can go back and change answers while time remains, and you can leave comments on questions, which PSI reviews but does not answer.
Because the books are allowed, the real test is speed. With 100 scored questions and some experimental ones in 240 minutes, you have a little over two minutes per item, so practice finding code sections fast: tab the chapters the outline weights most, learn each code's index, and answer the questions you know before digging for the rest.
Your score appears on screen at the end and a report is emailed. A failing report includes a diagnostic of strengths and weaknesses by area, which is the best guide for a retake. For timed practice against these outlines, ContractorPrepHQ's Arizona trade prep costs $149 and includes its Arizona statutes and rules practice; the statutes and rules practice alone is $99.
Common questions
- Is the Arizona SRE given at PSI?
- No. PSI's bulletin describes the SRE as a computer-based course that the ROC provides and maintains, available only online for $61. PSI delivers the trade and solar exams.
- What ID do I need at a PSI center in Arizona?
- One valid, unexpired ID with your photo and signature that matches the name you booked under, such as a state driver's license or ID card, a passport, a U.S. military ID or an alien registration card.
- Can I take the Arizona trade exam from home?
- Yes. PSI offers remote proctoring. You must pass PSI's system check, stay in camera view, and plan for no breaks and no scratch paper.
- What is the passing score?
- The three outlines covered here, B, B-1/B-2 and CR-37, all require 70 percent. Check the outline for your own classification, since question counts and times vary.
