ExploreAbout this exam
The Arizona Registrar of Contractors (AZ ROC) issues contractor licenses by classification, and the R-11 Electrical classification is the electrical trade credential within that system. AZ ROC - established in 1931 - licenses and regulates residential and commercial contractors, and licensing is tied to qualifying through examinations plus experience requirements. Candidates for an electrical classification generally face two written components: a trade examination covering electrical work, and a separate statutes-and-rules examination covering Arizona contractor law and ROC rules; AZ ROC publishes waiver request forms that reference exemptions from each of these requirements in limited circumstances. The trade exam is a multiple-choice test of electrical knowledge: system fundamentals, wiring methods and materials, overcurrent protection, grounding and bonding, equipment, motors and controls, plus applied areas such as estimating, jobsite safety, and project management, with Arizona statutes, rules, and National Electrical Code application woven throughout. Preparation works best as a staged effort - master code navigation and calculation first, then wiring and protection details, then business, safety, and Arizona-specific law - reinforced with timed practice questions and closed-book drills. Verify all current administrative details, including fees, scheduling, and scoring, directly with AZ ROC before you apply, since published figures change and were not confirmable from the retrieved source.
What you'll study
About AZ ROC R-11 Electrical preparation
Is the R-11 Electrical exam one test or two?
Plan for two written components: a trade examination on electrical work and a separate statutes-and-rules examination on Arizona contractor law and ROC rules. AZ ROC publishes distinct waiver request forms for the trade exam and for the statutes-and-rules exam, which confirms they are treated as separate requirements. Confirm your specific classification's requirements with AZ ROC before scheduling.
How many questions are on the exam and what score do I need to pass?
Those figures were not confirmable from the source material reviewed for this page, so we do not publish a number rather than risk giving you an outdated one. Item counts and passing scores are set by the exam provider and can be revised. Check the current candidate bulletin or contact AZ ROC licensing staff for the authoritative values.
How long is the test, and how much time should I allow per question?
The official time limit was not verifiable from our source, so treat any specific duration you hear secondhand with caution. A practical habit regardless of the clock: budget roughly a minute per item on calculation-light questions and bank the surplus for code-lookup and motor-calculation problems. Confirm the actual allotment with the test provider when you schedule.
What happens if I fail - can I retake it?
Retake rules, waiting periods, and any additional fees are set by AZ ROC and its testing vendor and were not confirmable here. In practice, candidates who fail usually receive a score report showing weak knowledge areas, which is the best study guide you can get. Ask AZ ROC about the current retake policy before you sit for the exam.
What is the best study order for the electrical trade exam?
Start with code navigation and Ohm's law calculations, because nearly every other topic depends on them. Then work through wiring methods and materials, overcurrent protection, and grounding and bonding - the highest-yield installation topics. Finish with equipment, motors and controls, then estimating, safety, and project management. Keep Arizona statutes and rules in a separate daily block so it is not crowded out.
How hard is the exam, and what trips people up most?
It is a working-electrician exam, not a trivia quiz, so difficulty comes from volume and precision rather than trick questions. The most common failure modes are slow code lookup, weak motor and conduit-fill calculations, and neglect of the statutes-and-rules portion because candidates assume trade knowledge alone carries them. Timed practice with the actual codebook in hand addresses all three.
Can the exam requirement be waived?
Possibly, in narrow circumstances. AZ ROC publishes an in-state waiver request form for the statutes-and-rules exam, an in-state waiver request form for the trade exam and experience requirement, and an out-of-state waiver request form for trade exam requirements. Eligibility is limited and decided by the agency, so read the forms and confirm with AZ ROC before relying on a waiver.
Where can I find the official exam details and application steps?
Go to roc.az.gov and use the Applicants and Contractors section, which links to license classifications, license classification requirements, licensing forms, licensing fees, and the rules and policies pages. AZ ROC also lists licensing and compliance email contacts and a customer service line. Always work from the agency's current pages rather than third-party summaries, including this one.
Is the exam offered online or in person?
AZ ROC has announced that contractor licensing exams moved online, and the agency maintains a news item on that transition. Testing arrangements, identity verification, and any in-person options are administered by the exam vendor. Confirm your scheduling options and technical requirements with the provider after AZ ROC approves your application.
