How often do I have to renew my Colorado journeyman electrician license?

PSI provides a 2026 NEC at the test center; you cannot bring your own. Unlike most other states, you also cannot write in it, highlight it, or use your own tabs, so practice navigating an unmarked book before test day.

Grounding and bonding is the single heaviest topic with 14 questions, more than any other area on the exam. Electrical calculations come in second at 9 questions and unlike code lookups, those you can't find by flipping through the NEC.

Colorado has reciprocity agreements with 14 states through NERA: Alaska, Arkansas, Idaho, Iowa, Minnesota, Montana, Nebraska, New Hampshire, New Mexico, North Dakota, Oklahoma, South Dakota, Utah, and Wyoming. Your license must have been earned by passing a state exam; grandfathered licenses don't qualify.

There's no waiting period. You can't rebook the same day you test, but you can call the next morning and be back in a seat as soon as the following day. The retake fee is $73.

Colorado electrician licenses must be renewed every three years, and the renewal process includes completing 24 hours of required continuing education.
