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

How CO-JP Testing Actually Works in 2026

If you're searching for fixed "CO-JP exam dates," it's worth resetting expectations early: the Colorado Journeyman Plumber License Exam is not administered on a quarterly or annual calendar like some licensing programs. The Colorado State Plumbing Board, under the Division of Professions and Occupations (DORA), contracts with PSI Services LLC to deliver the exam as a computer-based test available on a rolling, appointment-driven basis at PSI test centers. There isn't a registration deadline tied to a specific "spring window" or "fall window" - the real deadlines are the ones you create for yourself: when you finish your experience documentation, when DORA approves your eligibility, and when you feel ready across all 11 domains.

This matters for scheduling strategy. Instead of studying toward a distant fixed date months away, most CO-JP candidates work backward from their own readiness and book a PSI appointment once they've cleared eligibility and completed a structured review cycle. That flexibility is an advantage if you use it well and a trap if you let it drift - an open-ended schedule with no deadline tends to produce open-ended studying.

Eligibility Timeline Before You Can Schedule

Before PSI will let you book an appointment, DORA has to confirm you're eligible to sit for the exam. Colorado's licensure structure requires four years and 6,800 hours of qualifying practical experience, supported by documentation submitted through the DORA application process. This is the step that determines your real "exam date" - not a testing calendar, but the point at which your hours, sponsor verification, and paperwork are complete and accepted.

Practical scheduling advice: don't wait until your hours are finalized to start reviewing content. Begin working through the domain material - Water Supply, Vents, Fixtures and Equipment, and the rest - while your application is still in processing. That way, the moment your eligibility notice arrives, you're scheduling a PSI appointment for review and reinforcement, not a first exposure to the material. For a full breakdown of the experience and documentation requirements, see CO-JP Requirements 2026: Eligibility, Prerequisites & How to Qualify.

Fees, Rescheduling, and Retest Windows

Budgeting for the exam is straightforward compared to the scheduling logistics. The initial examination fee is $78. If you don't clear the passing threshold on your first attempt, a retest costs $73. Neither fee includes the cost of your independent study time, so it pays to schedule your first attempt only after a genuine review pass through every domain rather than treating the first sitting as a diagnostic run.

Because there's no fixed application cycle, rescheduling is handled directly through PSI's candidate portal rather than through a once-a-year sign-up period. If life gets in the way of your planned date, you're not waiting for the "next window" - you're simply picking a new open slot. That said, treat your first scheduled date as firm in your own mind. Repeated rescheduling tends to correlate with under-preparation, not logistics.

What the 240-Minute Test Day Looks Like

Knowing the exact format helps you schedule your day realistically - this isn't a quick in-and-out appointment. The CO-JP exam consists of 100 scored questions administered over 240 minutes, plus up to 10 additional unscored questions covered by a separate 30-minute allowance. Plan your travel and arrival time assuming a testing session that can run close to four and a half hours once you account for check-in and the unscored segment.

The exam is computer-based and open-book, but "open-book" here has strict conditions: PSI supplies the reference books at the test center. You are not permitted to bring your own copies, and you may not write, highlight, underline, or index the books PSI provides. An on-screen calculator is available, but plumbing formulas are neither supplied nor permitted - you need to know them, not just look them up. Passing requires 70 correct scored answers out of 100 (70%). If you want the exact scoring mechanics spelled out further, read CO-JP Passing Score 2026: Exactly What You Need to Pass.

Because Sanitary Drainage Systems carries the most weight, it's a reasonable rule of thumb to schedule your exam date only after you've run through at least two full review passes on that domain specifically, in addition to the other ten. A domain-by-domain breakdown of all 11 areas - Water Supply, Vents, Fixtures and Equipment, General Regulations, Traps/Interceptors/Separators, Storm Drainage Systems, Sanitary Drainage Systems, Indirect and Special Waste Piping, Isometric Analysis, Residential Fire Sprinklers, and Water Heaters - is covered in CO-JP Exam Domains 2026: Complete Guide to All 11 Content Areas.

The June 2026 Reference Bulletin Update

Test-date planning for CO-JP has one detail that trips up otherwise well-prepared candidates: the reference materials tied to your exam appointment are specified in PSI bulletin 11658, and that bulletin was revised June 18, 2026. It designates the 2021 International Plumbing Code (IPC) and 2021 International Residential Code (IRC) as the exam-specific references - and notably, Colorado amendments are not tested. Only the base IPC/IRC language matters on exam day.

Since PSI supplies the actual books at the test center - and prohibits any markup, tabbing, or personal copies - your own study materials serve one purpose: building familiarity with the code's organization and language before test day, not creating a tabbed reference you'll bring with you. A structured prep plan that mirrors this reality is laid out in CO-JP Study Guide 2026: How to Pass on Your First Attempt.

Picking a Test Date Around Your Weakest Domains

Since you control your own scheduling timeline, use that flexibility deliberately. Rather than picking a date arbitrarily and cramming toward it, work backward from a realistic review sequence across the 11 domains, front-loading the sections that carry the most exam weight or that you find conceptually hardest - commonly Sanitary Drainage Systems, Isometric Analysis, and Traps/Interceptors/Separators.

This sequencing isn't a generic four-week template - it's built around the fact that drainage, venting, and waste piping concepts overlap heavily, so tackling them in adjacent weeks reinforces retention instead of fragmenting it. If you're unsure how difficult any single domain will feel relative to the others, How Hard Is the CO-JP Exam? Complete Difficulty Guide 2026 walks through what makes certain sections harder to internalize than others. You can also run full practice sessions through our CO-JP practice test platform to gauge whether you're ready to lock in a PSI date.

After You Pass: Filing Deadlines and the Renewal Cycle Shift

One scheduling detail candidates often miss: passing the CO-JP exam does not by itself confer a license. You still need to file the license application with DORA after your passing result is recorded. Treat your exam date as one step in a two-part process, not the finish line - plan your post-exam paperwork timeline the same way you planned your study schedule.

There's also a structural change worth building into your long-term calendar. Currently, Colorado plumbing licenses renew on a two-year cycle. Under changes reflected in state legislation, licenses issued or renewed on or after March 1, 2027 shift to a three-year renewal cycle. If your license timing falls near that date, it's worth understanding how it affects your continuing education planning and renewal fees down the line - a detail explored further in Is the CO-JP Certification Worth It? Complete ROI Analysis 2026.

Continuing Education Deadlines Once Licensed

Passing your exam date isn't the end of deadlines - it's the start of a recurring one. Colorado requires eight hours of continuing education annually, including at least four code hours, with no more than two safety hours counted in each 24-month period. Mark these requirements on the same calendar where you track your renewal date so CE hours don't pile up right before a filing deadline.
