CO-MP Exam Dates 2026: Testing Windows, Deadlines & Scheduling

How CO-MP Scheduling Actually Works

The Colorado Master Plumber License Exam (CO-MP), administered by PSI Services LLC on behalf of the Colorado State Plumbing Board within DORA, is not a paper exam offered on a handful of dates each year. It's a computer-based test delivered at PSI test centers, which means candidates schedule an appointment rather than wait for a specific "testing window" the way you might for a paper-and-pencil licensing exam. Once your application is approved and your payment is processed, you select an available date and location that works for you.

That said, "scheduling flexibility" doesn't mean "no deadlines." There are hard boundaries around fee validity, retake timing, and how your exam result interacts with your license application. Understanding these mechanics matters just as much as knowing the content covered in the CO-MP Exam Domains 2026: Complete Guide to All 11 Content Areas.

Testing Windows in 2026

Rather than quarterly or semi-annual sittings, PSI test centers typically run appointments on a rolling basis throughout the year, subject to seat availability at your chosen location. For 2026, this means candidates should think in terms of "how soon can I get a seat" rather than "which quarter does the exam run in."

Practical implications for planning your 2026 attempt:

• Popular test centers in metro areas (Denver, Colorado Springs, Fort Collins) may fill up faster around peak licensing seasons, so book early once your eligibility is confirmed.
• Because payment is valid for one year, you have a full 12 months to actually sit for the exam after paying - but that also means the clock is running the moment you pay.
• If you fail and need a retake, that's a separate $73 payment with its own one-year validity, so don't let a retake payment sit unused for months without a plan.

If you're still deciding whether now is the right time to commit to a test date, reviewing How Hard Is the CO-MP Exam? Complete Difficulty Guide 2026 can help you gauge how much lead time you realistically need before booking.

Fees, Payment Validity, and Rescheduling

Money and timing are tightly linked in the CO-MP process. Here's what candidates need to keep straight:

Because your payment is only good for a year, waiting too long to schedule can force you to pay again even if you never sat for the test. This is one of the more overlooked scheduling risks - candidates sometimes pay, get busy with work, and lose the window entirely.

What to Confirm Before You Book

One detail that trips up even well-prepared candidates: the bulletin governing your exam content can change between when you start studying and when you actually sit for the test. The June 18, 2026 PSI bulletin specifies a 70% passing standard (84 out of 120 scored questions), based on overall performance rather than domain-by-domain minimums. But older bulletin language - including the introduction section - still references 2018 codes in places, even though the dedicated reference section specifies the PSI-supplied 2021 IPC and IRC as the actual testing references.

Before you lock in a date, confirm:

• Which code edition is currently listed as the official reference (2021 IPC/IRC per the dedicated reference section).
• The current passing score standard in effect for your scheduled window.
• That Colorado amendments are not part of the tested content - study time is better spent on the base code language.
• Whether any bulletin updates have been issued since you last checked, since PSI bulletins are the authoritative source over general assumptions.

Exam Day Format and Timing

Knowing the clock structure helps you schedule your day and pace your study sessions accordingly. The CO-MP exam consists of 120 scored multiple-choice questions administered in 270 minutes, plus up to 10 unscored (pretest) questions with an additional 30 minutes. Candidates won't know which items are scored versus unscored, so every question should be treated with equal seriousness.

Testing is available in both English and Spanish, and approved ESL accommodations include time-and-a-half and a qualifying translation dictionary. If you need either accommodation, factor in extra lead time when scheduling, since accommodation requests typically need to be arranged before your appointment is booked.

The 120 scored questions are distributed across all 11 domains, with heavier weighting toward the systems most central to plumbing work:

Sanitary Drainage Systems is the single largest domain at 22 questions, followed by Vents at 20 - together these two domains account for over a third of the entire scored exam. If your appointment is still weeks away, spend more of that runway on these two areas. For a complete walkthrough of every domain, see CO-MP Study Guide 2026: How to Pass on Your First Attempt.

Deadlines That Affect Your Schedule

Beyond the exam appointment itself, a few other timing rules shape when you should actually book:

• Take the exam before applying for licensure. The exam must be passed before you submit your license application - you can't apply first and test later.
• Passing doesn't establish experience eligibility. Master licensure separately requires 8,500 verified practical-experience hours, and you cannot verify your own experience. Passing the exam and accumulating verified hours are two independent tracks - schedule your test with this in mind rather than assuming a pass automatically clears you for licensure.
• Renewal cycle timing. The current renewal cycle runs March 1, 2025 through February 28, 2027, requiring eight CE hours each year (16 total for the cycle). First-time licensees by examination are exempt from CE until their first renewal. Three-year renewal terms begin March 1, 2027, so if you're licensed close to that transition, your first renewal timeline may look different than someone licensed earlier in the cycle.

These interlocking deadlines are exactly why it helps to review the full CO-MP Requirements 2026: Eligibility, Prerequisites & How to Qualify guide before you schedule your appointment - you want to make sure your experience-hour verification is on track at the same time as your exam date.

Building a Scheduling Timeline Around the Domains

Since CO-MP scheduling is candidate-driven rather than fixed to a calendar window, the smartest approach is to work backward from your target appointment date and allocate study weeks proportional to each domain's scored weight. A generic weekly study template doesn't reflect CO-MP's actual content distribution, so the schedule below ties each week to the domains that carry the most points.

Booking your PSI appointment for roughly the end of week 6 gives you a full pass through every domain weighted by its actual scored impact. For quick-reference review in the final days before your appointment, the CO-MP Cheat Sheet 2026: One-Page Review of Must-Know Facts is worth keeping on hand.

After You Pass: Licensure Timing

Passing your CO-MP appointment is a milestone, not the finish line. Since the exam must be completed before you apply for licensure, and since your 8,500 verified practical-experience hours are tracked and confirmed separately by someone other than yourself, it's worth lining up your hour verification paperwork in parallel with your study schedule - not after you've already passed.

Once licensed, keep the renewal clock in mind: the March 1, 2025-February 28, 2027 cycle requires 16 CE hours total, split evenly at eight per year, though first-time examination licensees are exempt until their first renewal.
