On the 2017 NEC
Arizona’s ROC electrical trade exams are written on the 2017 NEC, even though Phoenix and other cities now enforce newer editions. PSI’s bulletin says code questions use only the listed edition, and most newer study material is written for 2020 or 2023, which renumbered several of these rules. Every question here cites the 2017 section.

Frequently asked questions
How is the Arizona C-11 exam structured?+
One PSI trade exam of 110 scored questions in 4 hours, open book on the 2017 NEC, and you need 70% (77 correct). Services, feeders and branch circuits, grounding and bonding, and special occupancies are the largest areas (13 each), then conductors and cables (12) and photovoltaics (10). The same exam serves the commercial C-11 and the dual CR-11 license.
What do I need before I can sit the exam?+
Arizona licenses the business, not the electrician: the license names a qualifying party, who needs four years of practical or management experience in the trade, at least two of them in the past ten years. Accredited technical training can count for up to two years. You can test before applying, but your passing score must reach ROC with the application within two years.
Which code edition is the exam on?+
The 2017 NEC, plus NFPA 72 (2016) for the five fire alarm questions and OSHA’s construction standards (29 CFR 1926) for safety. PSI’s outlines were last revised June 8, 2023 and still list the 2017 NEC; no move to a newer edition has been announced. Arizona does not adopt the NEC statewide, so your city may enforce a newer edition than the exam tests.
Is it open book? What can I bring?+
Yes. Bring your own bound copies of the 2017 NEC, NFPA 72 (2016) and 29 CFR 1926. Highlighting, underlining, notes made before the exam and permanent tabs are allowed; writing in a book during the exam is not. Ugly’s Electrical References and the photovoltaic textbooks on PSI’s list are for study only, not the exam room. A silent, non-printing, non-programmable, non-scientific calculator is allowed.
Do I also need the Statutes and Rules exam?+
Yes. Every qualifying party also passes ROC’s own Statutes and Rules Exam ($61), an open-book online course and exam on Arizona contractor law. It cannot be waived unless you were an Arizona qualifying party in the same class within the past five years. Our practice exams cover the electrical trade exam only.
What is the pass rate?+
Arizona does not publish pass rates for the ROC trade exams.
Can I take the exam online?+
Yes. PSI offers the trade exams at its Arizona test centers (Flagstaff, Glendale, Phoenix, Tempe and Tucson), at any PSI center in the country, or remotely with an online proctor. Remote exams allow no scratch paper and no breaks; whether reference books may be used remotely is not stated, so check with PSI before choosing remote.
What does it cost?+
PSI charges $66 for the trade exam ($116 for two exams), and ROC’s Statutes and Rules Exam is $61. The two-year license fee is $580 for a commercial (C-11), $720 for a residential (R-11, including the recovery fund) and $850 for a dual (CR-11) license.
What happens if I fail?+
You see your score on screen and get a report of your weak areas. Under A.A.C. R4-9-106(D) you wait 30 days after a first or second failure and 90 days after that. A passing score must be submitted with your license application within two years.
Does Arizona accept a license from another state?+
Arizona has no reciprocity agreements. The Registrar may waive the trade exam for a qualifying party who held a comparable, exam-based license in another state within the past five years (A.A.C. R4-9-106(E)); the Statutes and Rules Exam still applies.
