What Does CO-JE Mean?

What the Letters Actually Mean

On this site, CO-JE is shorthand for the Colorado Journeyman Electrician License Exam. "CO" is Colorado, "JE" is Journeyman Electrician, and the exam is the knowledge test you pass on the way to a Colorado journeyman electrician license.

That distinction matters because several unrelated credentials in other fields share the same two letters. Nothing in this article applies to them. Every fact below concerns the Colorado electrical licensing exam specifically. For other framings of the same question, see our pages on what CO-JE is and what CO-JE stands for.

Who Is Behind the Exam

Three parties are involved, and mixing them up causes real confusion for candidates:

• Colorado State Electrical Board - part of the Colorado Department of Regulatory Agencies (DORA), Division of Professions and Occupations. It sets the exam scope, reviews your experience and education, and issues the license.
• PSI Services LLC - the testing provider. PSI administers the computer-based exam at its test centers and publishes the Candidate Information Bulletin.
• This site - CO-JE Exam Prep is an independent study resource. We are not the issuer, and our domain is not a government website.

The Board's candidate bulletin (updated June 18, 2026) is the controlling source for exam content and rules. Treat it, not any third-party summary, as final.

How the Exam Is Built

Two points deserve attention. First, the 240-minute figure describes the scored component. If your form includes experimental items, your appointment can run up to 30 minutes longer. Second, the 70% standard is a passing threshold, not a pass rate. No current first-attempt or overall candidate pass rate has been publicly verified; our pass rate page explains what can and cannot be said. For the exact scoring math, see CO-JE passing score.

Open book does not mean easy

PSI supplies the NEC and a formula page. You may not bring personal references, and writing, highlighting, underlining, or indexing the supplied references is prohibited. That means advice from other states about tabbing your own code book does not apply here. Your speed comes from knowing how the NEC is organized and from practicing navigation in the same on-screen environment, not from pre-marked pages. The bulletin also recommends reviewing electrical theory and common formulas in addition to code navigation, since some questions will not be answerable by looking up a single section. For a candid look at the difficulty, read how hard the CO-JE exam is.

The 13 Content Headings

The Board's bulletin lists 13 content headings along with published item allocations. Official percentage weights are not published, so we report counts only. In heading order, the allocations are 11, 9, 14, 6, 8, 5, 5, 6, 5, 6, 4, 2, and 9, totaling the 90 scored items.

A smaller heading is not an ignorable one. Photovoltaics has only 2 items, but those are points you can pick up with a modest investment if you are comfortable with the relevant NEC articles. The full breakdown, with study angles for each heading, is in our complete guide to all 13 content areas. Note that any article subtopics we write (for example, load calculation drills) are editorial study treatments, not additional official domains.

The NEC Edition Question

This is the part of the exam situation most likely to trip up a candidate, so read it carefully. The sources conflict:

• The retrieved bulletin text states that, effective August 1, 2026, questions are consistent with NEC 2026 and PSI supplies the 2026 NEC.
• That same text says a 2023 book may be requested until December 1, 2026, after which it is no longer an option.
• Older introductory and rendered reference text in the same materials still specifies NEC 2023.

Because Colorado's exam situation is in transition, build your preparation around the NEC edition PSI confirms for your appointment date. Our exam dates and scheduling guide covers the timing side of this.

What Qualifies You to Apply

Colorado requires you to take and pass the exam before submitting the license application, and passing alone does not establish licensing eligibility. The Board reviews your documented experience and education separately. Under the current rules as enacted by SB25-165 (signed June 3, 2025):

• 8,000 qualifying hours of experience over at least four years.
• Within that, 2,000 hours over at least two years in commercial, industrial, or substantially similar work.
• At least 288 classroom-training hours during the last eight years of training, apprenticeship, or practical experience, documented separately from on-the-job hours.

SB25-165 also lets the Board credit older training when you show at least four additional hours on the current or immediately previous NEC or other adopted standards. That is a Board-reviewed exception, not automatic credit. These changes supersede older descriptions you may still find online, such as the 4,000-hour commercial/industrial figure and the earlier four-year classroom lookback. If you see those numbers, the source is out of date.

The training rules also reference 10 to 40 hours of OSHA-curriculum safety instruction within the 288-hour requirement (Rule 1.7(D)(1)(b)). That wording is corroborated in an older version of the Board's rules, and a newer rule version shows an effective date of July 15, 2026, so confirm the current rule text with the Board before relying on it. Full detail is in our CO-JE requirements guide.

Fees, Scores, and Retakes

The exam fee pays for the test only. The initial licensing charge and renewal charge are separate costs that we have not independently verified, so budget for them by checking the Board's current fee information. Study materials, classroom hours, and any prep course are additional. See the full pricing breakdown for how to think about total cost.

If you do not pass

After a failed attempt, the bulletin permits you to schedule from the following day for the next available test date, paying the retest fee. That is a rule about when you may schedule, not a promise that a seat will be open the next morning. Plan your retake window with real availability in mind.

After You Pass: Licensing and Renewal

Passing the exam is one step. You then submit your application with documentation of experience and classroom hours to the Board. Application forms are available through the State Electrical Board Applications and Forms page on the DORA site.

Renewal runs on a three-year cycle with 24 continuing education hours, including at least four hours on NEC changes and no more than four credited safety hours. Initial licenses obtained by examination between October 1, 2023 and September 30, 2026 are exempt from CE until after their first renewal. The current cycle expires September 30, 2026. A renewal window running past that date was noted in earlier review but could not be re-verified, so do not treat it as permission to practice on an expired license. Confirm your deadline with DORA.

If you are weighing whether the whole path is worth the effort, our pieces on whether the credential is worth it and earnings address that; note that salary claims require separately sourced wage data, and none are asserted in this article.

A Study Sequence Built Around the Item Counts

Rather than a generic schedule, tie your weeks to where the points are. This is an example sequence, not an official curriculum.
