- DOPL's April 2025-April 2026 summary reports 70% on Plumbing Theory and 54% on the shared Plumber Practical.
- These are separate cohort results, not a combined or first-attempt-only journeyman pass rate.
- The written exam needs 70% on 100 questions in four hours, open book, computer-delivered.
- The practical has two 37-point projects; failing either one means retaking the entire practical.
The Real Numbers Behind "Pass Rate"
If you've been searching for a single "UT-JP pass rate" figure, the honest answer is that Utah's licensing data doesn't hand you one clean percentage. The official score summary covering April 29, 2025 through April 29, 2026 reports two separate figures: 70% for Plumbing Theory and 54% for the shared Plumber Practical. Those numbers come from the Utah Division of Professional Licensing (DOPL) and Prov, the testing provider that administers both the written and practical exams for journeyman plumber licensure in Utah.
Notice the wording carefully. This is not a "first-attempt pass rate" and it is not a combined journeyman licensure rate. It's a cohort-level summary of outcomes on each exam component over that reporting window. That distinction matters because candidates often assume these percentages describe their personal odds of passing on the first try - they don't, at least not directly.
What the Official Summary Doesn't Say
Before you build a study plan around these two figures, understand their limits:
- They don't separate first-time test-takers from repeat candidates.
- They don't break results down by domain, so you can't tell from the summary alone whether candidates missed more questions on Fuel Gas versus Water Heaters.
- They don't tell you whether practical failures came from the Plastic Assembly project, the Copper Assembly project, or both.
- They reflect a specific 12-month window and can shift as new cohorts test.
In other words, the summary is a snapshot, not a roadmap. For an actual roadmap of what to study and in what order, the UT-JP Exam Domains 2026: Complete Guide to All 13 Content Areas breaks the blueprint down domain by domain, and the UT-JP Study Guide 2026: How to Pass on Your First Attempt translates that into a preparation sequence.
Key Takeaway
Treat the 70%/54% figures as a directional signal that the practical assembly work deserves more rehearsal time than passive review of code text - not as a prediction of your specific result.
Written Exam Mechanics That Drive Outcomes
The Utah Plumber Written Exam is 100 questions, computer-delivered, multiple choice, and open book, with a four-hour time limit. Passing requires a 70% score. Each attempt costs $85, and you can sit for it at an approved Prov testing center or remotely through ExamRoom proctoring.
"Open book" is often misread as "easy." It isn't. With 100 questions and four hours, you have roughly two to three minutes per question if you're flipping through a code book for every answer - that pace collapses quickly if you don't already know where to look. The current Prov reference list uses the 2024 International Plumbing Code (ISBN 978-1959851738). An older bulletin referencing the 2021 IPC is outdated and should not guide your preparation; always confirm you're studying from the current edition matched to Prov's active reference list.
For a granular breakdown of exactly what 70% means in terms of raw question count and how the scoring threshold is applied, see UT-JP Passing Score 2026: Exactly What You Need to Pass.
Practical Exam Mechanics and the 54% Question
The practical exam is a separate $78 attempt fee and is administered in person only - no remote option. Candidates get two hours and thirty minutes to complete two graded projects:
- Plastic Assembly - worth 37 points
- Copper Assembly - worth 37 points
You are responsible for supplying the specified tools, materials, and safety glasses. Preparation should include practicing rolling offsets, since that skill shows up repeatedly in practical prep guidance and is a common place where time gets lost under pressure. Critically, if you fail either project, you must retake the entire practical - there's no partial credit carryover between attempts.
Given that the shared Plumber Practical result sits at 54% in the current summary window, this component deserves real bench time, not just conceptual review. Timed, full run-throughs of both assemblies - with the actual tool list you'll use on exam day - matter more here than they do for the written portion.
Practical Assembly Discipline
Two hours and thirty minutes for two 37-point projects leaves little room for redoing work. Candidates who rehearse the full sequence under time pressure, rather than practicing joints in isolation, tend to manage the clock better.
- Time each assembly separately during practice, not just the combined total
- Rehearse rolling offset layout and measurement before assembling
- Confirm your tool and material list matches Prov's specification exactly
Domains That Decide Who Passes
The written exam's 100 questions are distributed across 13 official domains. Two of them are weighted slightly heavier than the rest, with nine questions each:
- Plumbing Math (9 questions)
- Plumbing Safety (9 questions)
The remaining 11 domains round out the blueprint:
The 13 Written Exam Domains
- Basic Valves
- Drain, Waste, and Vent (DWV)
- Fuel Gas
- Hydronics
- Indirect & Special Waste
- Pipe and Fittings
- Plumbing Drawing
- Plumbing Fixtures
- Plumbing Math
- Plumbing Safety
- Structural Penetration, Insulation
- Water Heaters
- Water Supply
Because Plumbing Math and Plumbing Safety carry the highest per-domain question counts, weak spots there have an outsized effect on your overall score compared to lighter domains. If you're unsure how difficult the exam feels relative to the code knowledge you already have on the job, How Hard Is the UT-JP Exam? Complete Difficulty Guide 2026 walks through that comparison in more depth. For a full domain-by-domain study breakdown, the domains guide linked above is the more detailed companion resource.
The Eligibility Gate Before You Ever Test
Pass rate discussions only matter once you're eligible to sit for the exam. Standard full-license eligibility in Utah requires completion of an approved apprenticeship program - including 576 classroom hours - plus 8,000 hours of supervised, licensed plumbing experience. A separate 16,000-hour supervised experience route exists for candidates without the classroom component. There's also an earlier, distinct pathway allowing exam eligibility after seven semesters (or competency-exam equivalence) combined with 6,000 licensed apprentice hours - but that's an earlier eligibility track, not the same as full-license eligibility.
One procedural change to note for 2026: effective January 19, 2026, first-time candidates registering with Prov must electronically submit a Verification of Plumber Experience as part of registration. Build this into your timeline early, since it's a registration prerequisite, not a same-day formality. The UT-JP Requirements 2026: Eligibility, Prerequisites & How to Qualify article covers each pathway and the documentation involved in more detail, and UT-JP Exam Dates 2026: Testing Windows, Deadlines & Scheduling covers how registration timing interacts with test scheduling.
A Domain-Based Study Timeline
Generic study techniques only help if they're mapped to the actual UT-JP blueprint. Since Plumbing Math and Plumbing Safety each account for nine of the 100 written questions, and the practical carries the lower reported result at 54%, a sensible allocation front-loads those areas rather than spreading time evenly across all 13 domains.
Plumbing Math and Plumbing Safety
- Drill calculation problems until formulas are automatic, not looked-up
- Review safety scenarios likely to appear as applied questions rather than definitions
Code-Heavy Domains
- DWV, Fuel Gas, Water Supply, and Water Heaters using the current 2024 IPC reference
- Practice locating sections quickly to simulate open-book time pressure
Remaining Written Domains
- Basic Valves, Hydronics, Indirect & Special Waste, Pipe and Fittings, Plumbing Drawing, Plumbing Fixtures, Structural Penetration/Insulation
- Full timed practice exams under the four-hour limit
Practical Bench Time
- Full run-throughs of Plastic Assembly and Copper Assembly within the 2.5-hour window
- Rolling offset repetition and tool-kit verification against Prov's specification
This sequencing pairs naturally with the domain guide and the broader UT-JP Study Guide 2026: How to Pass on Your First Attempt, and you can pressure-test your readiness along the way using timed practice questions on the main UT-JP practice test platform.
Written vs. Practical: Side-by-Side
| Component | Written Exam | Practical Exam |
|---|---|---|
| Fee per attempt | $85 | $78 |
| Format | 100 questions, multiple choice, open book | Two graded assembly projects |
| Time limit | 4 hours | 2 hours 30 minutes |
| Passing standard | 70% score | Pass both projects (37 pts each) |
| Delivery | Approved center or ExamRoom remote | In person only |
| Retake rule | Retake written attempt | Retake entire practical if either project fails |
| Reported result (Apr 2025-Apr 2026) | 70% (Plumbing Theory) | 54% (Plumber Practical) |
The cost and structure differences are one reason candidates budget carefully for retake scenarios; the full fee breakdown, including renewal costs, is covered in UT-JP Certification Cost 2026: Complete Pricing Breakdown.
Who's Watching These Results
Licensed journeyman plumbers in Utah work for mechanical contractors, plumbing service companies, and property management operations that need DOPL-licensed staff on payroll for code-compliant installation and repair work. Employers evaluating candidates often care less about which attempt you passed on and more about whether you hold the license and can demonstrate competence across domains like Water Supply, DWV, and Fuel Gas on the job. If you're weighing whether the licensure investment pays off relative to unlicensed work, Is the UT-JP Certification Worth It? Complete ROI Analysis 2026 and UT-JP Salary Guide 2026: Complete Earnings Analysis address that question directly, and a quick review with practice questions modeled on the real blueprint can help you gauge readiness before you commit to a test date.
Frequently Asked Questions
No. These are separate cohort results for the April 29, 2025-April 29, 2026 reporting window - 70% for Plumbing Theory and 54% for the shared Plumber Practical. They are not combined into a single journeyman pass rate, and they aren't limited to first-attempt candidates only.
The data doesn't state a specific cause, but the practical requires completing two 37-point assembly projects - Plastic Assembly and Copper Assembly - within 2 hours 30 minutes, with no partial credit for retaking just one project if you fail either. That structure leaves less room for error than the open-book written format.
Plumbing Math and Plumbing Safety each carry nine of the 100 questions, the highest count among the 13 domains, so weaknesses there affect your score more than gaps in lighter-weighted domains.
Not necessarily. With 100 questions in four hours, relying heavily on searching the 2024 IPC for every answer can burn through your time budget. Strong code-book familiarity going in matters more than the open-book allowance itself.
Effective January 19, 2026, first-time candidates registering with Prov must electronically submit a Verification of Plumber Experience as part of the registration process, ahead of scheduling either exam.
