What Does CO-ME Mean?

What CO-ME Actually Means

CO-ME is shorthand for the Colorado Master Electrician License Exam - the computer-based test that electricians in Colorado must pass on the path to becoming a licensed master electrician. It is not a generic industry certification and it is not affiliated with any national credentialing body that happens to share a similar acronym. It is a state-specific licensing exam tied directly to Colorado's electrical licensing statutes and rules.

If you're searching "what does CO-ME mean" because you've seen it referenced in a study guide, job posting, or contractor forum specific to Colorado, this is the exam being discussed: a regulatory checkpoint administered on behalf of the state, not a voluntary skills badge. For a broader orientation to the credential itself, see What Is CO-ME? and CO-ME Meaning.

Who Issues and Administers the Exam

The Colorado State Electrical Board, operating under DORA, sets the licensing framework and eligibility rules for master electricians in Colorado. The actual exam delivery - scheduling, testing centers, scoring - is handled by PSI Services LLC, a third-party testing vendor. This is a common structure in state licensing: the regulatory board defines who is eligible and what the license means, while the testing vendor handles the logistics of administering a secure, standardized exam.

Understanding this split matters practically. Questions about eligibility, license applications, and renewal rules go through DORA's electrical licensing channels. Questions about exam scheduling, fees, and the candidate bulletin go through PSI. Candidates sometimes assume the exam vendor sets licensing requirements, but PSI's role is limited to administering the test according to the content outline the board approves.

Exam Format and Question Mechanics

The CO-ME is a computer-based, multiple-choice examination. Understanding its exact structure changes how you should pace your study and your test-day strategy:

• 90 scored questions administered in 240 minutes.
• Up to 10 additional unscored (pretest) questions, with 30 extra minutes allotted for them. You won't know which questions are unscored, so every question should be treated as if it counts.
• Passing score: 70%, or 63 of 90 scored questions correct. There is no requirement to pass each domain separately - a weak showing in one domain can be offset by strength in another, as long as your overall score clears the threshold.
• The testing center provides the NEC code book and a formula/reference page. You may not bring your own reference materials, and the supplied book cannot be written in, highlighted, underlined, or indexed. Navigating an unmarked code book quickly is itself a skill you need to practice.
• An onscreen calculator is available for load calculations and other math-heavy questions.

Because the passing threshold is applied across the whole exam rather than domain-by-domain, your prep strategy should prioritize the highest-weighted domains first, since they have outsized influence on your total score. For the exact math behind the 70% threshold, see CO-ME Passing Score 2026: Exactly What You Need to Pass.

The 13 Domains Behind the Acronym

The content outline behind CO-ME spans 13 domains. Below is the official scored-item allocation, which tells you exactly how much of your study time each area deserves relative to the others.

Domains 8, 9, and 13 (Special Occupancies, Special Equipment, and Electrical Calculations) each carry 9 questions, making them a meaningful secondary tier. A full walk-through of every domain's subtopics and how they interconnect is available in CO-ME Exam Domains 2026: Complete Guide to All 13 Content Areas.

Eligibility: Why Passing Isn't the Finish Line

One of the most misunderstood aspects of the CO-ME is the relationship between the exam and the license itself. Passing the exam is required before you can submit your DORA license application - but passing does not waive the underlying experience and education requirements. The exam and the license application are two separate hurdles that both need to be cleared.

Colorado offers two primary routes to master electrician eligibility:

• Experience-based route: 10,000 hours of qualifying work over at least five years, including planning, layout, and supervision experience beyond what's required at the journeyman level.
• Education-based route: Available to qualifying electrical-engineering graduates and graduates of approved trade schools or community-college programs.

Whichever route applies, candidates must submit employer or master-level experience verification along with any applicable education transcripts as part of the license application process. It's also worth noting that electrical contractor registration is a separate credential from the individual master electrician license - holding one does not automatically confer the other.

Fees, Scheduling, and the NEC Cycle

Budgeting for the CO-ME is straightforward but worth planning around:

• Initial exam fee: $78
• Retest fee: $73

Because the exam is delivered on a rolling, computer-based schedule through PSI test centers rather than fixed annual sitting dates, availability depends on center capacity in your area. A detailed look at how scheduling works and how to plan around it is in CO-ME Exam Dates 2026: Testing Windows, Deadlines & Scheduling.

After You Pass: License and Renewal

Once you've passed and your DORA application (with experience/education documentation) is approved, your license enters a renewal cycle. Active master electrician licenses in Colorado renew every three years and require 24 continuing-education hours, structured as follows:

• At least 4 hours must cover NEC changes.
• No more than 4 hours may count as safety training.
• The first renewal after a license is issued by examination is exempt from the CE requirement.
• CE records must be retained for seven years.

This renewal structure is worth knowing before you even sit for the exam, because it shapes how you'll continue engaging with code updates long after your initial license is issued.

A CO-ME-Specific Prep Approach

Generic study advice - spaced repetition, timed drills, flashcards - only helps if it's applied to the right material in the right order. Given the domain weighting, a sensible allocation looks like this:

This kind of weighted schedule is the backbone of CO-ME Study Guide 2026: How to Pass on Your First Attempt. If you want a fast-reference companion for last-minute review, CO-ME Cheat Sheet 2026: One-Page Review of Must-Know Facts condenses the highest-yield facts into one page. And if you're still calibrating how much runway you need before test day, How Hard Is the CO-ME Exam? Complete Difficulty Guide 2026 breaks down what makes this exam challenging beyond raw content volume.

Practicing under realistic conditions matters as much as content review. Working through timed, scored practice sessions on our CO-ME practice test platform helps you get comfortable with the pacing - roughly 2.6 minutes per scored question - before you're facing the real 240-minute clock. You can also use the main practice site to build familiarity with the multiple-choice question style used across all 13 domains.
