ICC Electrician Exam: Format & How to Prepare (2026)

If your state or city licenses electricians through the International Code Council, your licensing exam is an ICC exam rather than a state-built test. The ICC runs a national testing program that many licensing agencies use, so the same exam program shows up across multiple states. This guide explains what the ICC electrician exam is, who uses it, how it is formatted, and how to prepare.

What is the ICC electrician exam?

The International Code Council (ICC) operates a National Contractor/Trades examination program. Licensing agencies contract with the ICC to deliver standardized trade exams, including electrician exams, so they do not have to develop and maintain their own. The ICC writes and scores the exam; the licensing agency decides who qualifies to sit for it and who is ultimately awarded a license. Passing the ICC exam does not by itself grant a license. It satisfies the testing requirement that your local board or department then combines with your experience and application.

The ICC offers separate electrical exams by license level, most commonly journeyman, master, and residential. The level you take depends on the license your jurisdiction is issuing.

Who uses the ICC exam?

ICC exams are used by a mix of state boards and local (city or county) jurisdictions. Kentucky, for example, moved its electrician licensing to ICC-administered testing, and a number of municipal licensing programs use ICC exams as well. Because adoption is decided jurisdiction by jurisdiction, two electricians in neighboring states can sit for completely different exam programs.

Before you register, confirm the testing vendor named in your jurisdiction's candidate information bulletin. If it lists the ICC (or "Code Council Contractor/Trades testing"), the guidance below applies. If it lists PSI, Pearson VUE, or Prometric instead, your exam is delivered by a different vendor, though the underlying NEC content is similar.

See your state's specifics on the state exam pages, or compare exam formats and vendors across all 50 states.

Format: open book and NEC-based

ICC electrician exams are open book and based on the National Electrical Code. Key points that hold for most ICC electrical exams:

• The exam is open book. You bring an approved, tabbed copy of the NEC edition your jurisdiction has adopted (NEC 2023 in most states).
• The journeyman exam typically runs around 80 questions with a time limit near four hours.
• The common passing score is 70 percent, though your jurisdiction sets the official cut score.
• Questions are multiple choice and reference specific NEC articles, tables, and calculations.

Always check your jurisdiction's bulletin for the exact question count, time limit, passing score, approved code edition, and reference materials, because the ICC lets each licensing agency configure those details.

What the ICC exam covers

Because the ICC exam is built on the NEC, it tests the same core articles as any other electrician licensing exam. The most heavily weighted topics for the journeyman level are:

• Branch circuits (Article 210)
• Load calculations (Article 220)
• Services (Article 230)
• Overcurrent protection (Article 240)
• Grounding and bonding (Article 250)
• Conductor sizing and Table 310.16
• Box fill (Article 314)
• Motors (Article 430)
• Conduit fill (Chapter 9)

Master-level ICC exams add broader and more advanced content, including transformers, air conditioning equipment, hazardous locations, and more complex commercial load calculations.

How to prepare for the ICC exam

The ICC exam rewards two things: knowing the code and finding it fast. Since the exam is open book, raw memorization matters less than being able to navigate a tabbed NEC quickly and apply it under time pressure.

A practical preparation plan:

1. Tab your NEC 2023 codebook for the articles listed above so you can reach them in seconds.
2. Drill timed practice questions that mirror the exam format, focusing on load calculations and grounding, where most candidates lose points.
3. Review every question you miss against the cited NEC article so you learn where the answer lives, not just what it is.
4. Take full-length timed sets in the final weeks to build pacing for the four-hour window.

GetLicenseReady's question bank is built on NEC 2023, the code most ICC jurisdictions test on, and every answer cites the exact article so you practice navigation as you study. Start with the journeyman exam prep guide, work through the free NEC study guide, and keep the NEC quick reference handy while you practice.
