Colorado Electrician License and Exam Prep, in One Place

Colorado licenses residential wiremen, journeymen and masters by name, and registers the contracting business behind them. The exam is open book only in the sense that PSI puts a book on the desk, and you may not mark it. Every page here says which rule it read and links it.

30 practice questions, free

They work with no account and no network. The full bank is 500, and the other 470 carry what every question here carries: the arithmetic worked out, and a line on each wrong option naming the error that produces it.

$79 once for the other 470, if you want them. One payment, no subscription, no account, no password, and no email address on file with us. Access does not expire and there is nothing to renew: every question added to the bank later is yours at no extra cost.

Buying for a crew, a shop or a class? One payment covers everybody. Each person claims a seat with their own email, on any device, and there is nothing for you to hand out or keep track of. The seat licenses sit under the buy button on the practice test page.

What people come here for

Every page below is on this site, and every figure on it carries the board page, the rule or the bulletin it came from.

The path

The licenses

Rules and money

The exam

The code

Study

Your city

What a person in each of these eight cities does to get licensed, the training programs there, the nearest test center and the local wage.

Hands-on labs

In a lab you drag the conductor, turn the dial or drop conductors into a box, and the page answers with the number it just changed and the code section behind it. All four are free and none of them asks for an account.

How it works

  1. Sit thirty questions against the clock. The practice test is timed and scored by content area. Thirty questions are free, they run with no account and no network, and every miss comes back with the arithmetic worked out and the section named.
  2. Work the area you lost. The score report names the area you are weakest in. Practice questions by topic holds 54 topics with 25 questions each, free.
  3. Open the bank when the free set runs out. $79 once opens the other 470 questions and the seven remaining rungs of the calculation ladder. One payment, no subscription, no account, and no email address on file with us.
Put it to the test

Thirty free questions, timed, with the working shown

PSI provides the National Electrical Code and a formula page at the test center, bars writing, highlighting, underlining and indexing on them, and allows no other materials. The questions have followed the 2026 edition since 1 August 2026, and the 2023 book is provided on request until 1 November 2026.
