- WI-JP is administered as two separate parts: 87 questions/3 hours, then 120 questions/3 hours (207 total, 6 hours).
- Passing standard is 70% on each open-book part, not a single combined score.
- Pearson VUE charges $90 per part ($180 total); LicensE handles application/credential fees separately.
- Only nine specific reference items are allowed, and printed notes must be three-hole-punched inside your binder.
The One-Page WI-JP Overview
If you only had five minutes before walking into a testing center, this is the page you'd want. The Wisconsin Journeyman Plumber License Exam (WI-JP), class code 7630, is issued by the Wisconsin Department of Safety and Professional Services (DSPS). Candidates who complete a recognized plumbing apprenticeship and gain eligibility approval through DSPS's LicensE system can sit for the exam either at a DSPS examination location or via Pearson VUE's computer-based testing network.
This cheat sheet condenses the mechanics you need cold: question counts, timing, references, fees, and testing locations. For deeper prep on any single piece, see the full WI-JP Study Guide 2026 or the breakdown of WI-JP requirements. If you want to drill against realistic questions before test day, our practice test platform mirrors the two-part format described below.
Exam Structure: Part 1 and Part 2
The DSPS credential checklist is explicit: this is not one continuous exam. It is two distinct parts, each with its own question count and time block.
| Component | Questions | Time Allowed | Passing Score |
|---|---|---|---|
| Part 1 | 87 | 3 hours | 70% |
| Part 2 | 120 | 3 hours | 70% |
| Combined Total | 207 | 6 hours | 70% on each part |
Both parts are open book, which changes how you should prepare - the goal isn't memorizing every code number, it's knowing exactly where to find it fast. For a full explanation of how the scoring standard applies to each part independently, read WI-JP Passing Score 2026. And if you're wondering how the two-part structure affects overall difficulty, How Hard Is the WI-JP Exam? walks through it in detail.
Key Takeaway
Treat Part 1 and Part 2 as two separate exam-day events. Plan your reference tabs and binder organization around each part's likely emphasis rather than trying to prep for "the exam" as one blob.
The Nine Permitted References
Because both parts are open book, what you're allowed to bring in matters as much as what you know. DSPS permits exactly nine reference items, and nothing else:
Approved Reference List
- One binder containing Wisconsin Statutes chapters 145 and 106, SPS 305, SPS 381-387, SPS 302, SPS 325, and printed notes
- NFPA 13D (2019)
- NFPA 24 (2019)
- At-Grade Pressure Distribution Component Manual
- Holding Tank Component Manual
- In-Ground Soil Absorption Component Manual
- Mound Component Manual
- Pressure Distribution Component Manual
- Multi-Purpose Piping Systems Design Manual
Printed notes must be three-hole-punched and placed inside the binder - loose papers are not allowed. Also prohibited: practice or previous exams, sticky notes, removable tabs, and paperclips. Tabs that came factory-installed on bound code books are fine, as are three-ring paper dividers with tabs, and architect/engineer scale rulers are permitted for POWTS layout questions.
Fees, Eligibility, and Registration Mechanics
Money and paperwork trip up more candidates than the actual plumbing content does. Here's the mechanics in plain terms.
- Standard eligibility: completion of a recognized plumbing apprenticeship.
- Out-of-state apprenticeship route: a five-year program with at least 576 hours of related instruction.
- Comity route: available for qualifying experienced out-of-state journeyman licensees, described in the DSPS application materials.
- Pearson VUE fee: $90 per part, $180 total for both parts.
- Application/credential fees: handled separately through LicensE, not through Pearson VUE.
For the full cost picture - including how the exam fee compares to renewal fees down the road - see WI-JP Certification Cost 2026. If you're still confirming you qualify to sit for the exam at all, WI-JP Requirements 2026 covers each eligibility path in more depth.
Key Takeaway
Eligibility approval happens in LicensE before you ever touch Pearson VUE. Get that approval locked down early so scheduling doesn't become your bottleneck.
Pearson VUE Test Centers and Scheduling Rules
Wisconsin plumbing exams through Pearson VUE are restricted to a specific list of centers: Eau Claire, Madison, Brookfield, Kenosha, Ashwaubenon, and Milwaukee. There's no option to test at a Pearson location outside that list.
One rule catches people off guard: once you select Pearson VUE for your application, you cannot revert that application back to a DSPS examination location. Choose deliberately. Also note that a passing result is valid for one year, and if you need a retake through Pearson, you'll need new DSPS exam eligibility first - passing one part doesn't carry forward indefinitely if the other part lapses.
For exact scheduling windows and how to sequence Part 1 and Part 2 bookings, check WI-JP Exam Dates 2026.
Core Topics to Master Before Test Day
WI-JP doesn't publish domain-percentage weightings the way some credentials do - the exam parts and reference titles themselves are the organizing structure, not a topical breakdown. That means your best strategy is to build your study plan around the state-code and POWTS (Private Onsite Wastewater Treatment System) references directly, since those are what you'll actually be tested against and allowed to consult.
Wisconsin Statutes & Administrative Code (SPS 305, SPS 381-387, SPS 302, SPS 325)
These chapters form the statutory backbone of the exam. Candidates must be comfortable navigating chapter numbering quickly, since open-book format rewards speed of lookup over rote memorization.
- Know where plumbing installation standards sit within SPS 382-384 vs. general provisions
- Understand how Wisconsin Statutes 145 and 106 interact with administrative code sections
POWTS Component Manuals
The five component manuals (At-Grade Pressure Distribution, Holding Tank, In-Ground Soil Absorption, Mound, and Pressure Distribution) cover onsite wastewater system design and installation specifics that show up heavily in one or both parts.
- Practice locating sizing tables and setback distances quickly under time pressure
- Be ready to cross-reference between a component manual and SPS 383 in the same question
Fire Protection Piping (NFPA 13D and NFPA 24, 2019 editions)
These govern residential fire sprinkler systems and private fire service mains. Even candidates who rarely install fire protection piping in daily work need to know how to navigate these two documents under exam conditions.
- Familiarize yourself with 13D sprinkler spacing and water supply basics
- Know how NFPA 24 addresses underground main sizing and testing
Multi-Purpose Piping Systems
The Multi-Purpose Piping Systems Design Manual covers combined potable-water and fire-suppression piping design - a niche but exam-relevant topic that candidates often under-prepare for.
- Understand where multi-purpose piping rules diverge from standard supply piping rules

A Focused Two-Part Study Plan
Generic study techniques only matter here to the extent they map onto WI-JP's specific two-part structure. Use spaced repetition and timed drills, but schedule them against the actual references you'll carry into the room.
Build the Binder
- Assemble Wisconsin Statutes 145/106, SPS 305, SPS 381-387, SPS 302, SPS 325 into your permitted binder
- Draft and three-hole-punch printed notes now, not the week before
Part 1 Emphasis
- Run timed drills under a 3-hour, 87-question simulation
- Focus lookup speed on statutes and SPS administrative code sections
Part 2 Emphasis
- Simulate the 120-question, 3-hour block
- Drill POWTS component manuals and NFPA 13D/24 lookups until they're fast, not just familiar
Full Dress Rehearsal
- Confirm binder contents match the nine permitted items exactly - no extras, no loose papers
- Review LicensE eligibility confirmation and Pearson VUE center choice
If you want a more detailed week-by-week breakdown with milestones, the WI-JP Study Guide 2026 goes deeper into pacing strategy, and our practice test platform lets you rehearse both part lengths under realistic time pressure.
After You Pass: Renewal and Supervision Rules
Passing WI-JP is not the finish line - it's the start of a licensing cycle with its own deadlines. Keep these facts on your cheat sheet even after test day:
- Passing results are valid for one year; if you don't complete both parts or finalize licensure within that window, you'll need new DSPS eligibility to retake through Pearson.
- License renewal occurs every four years, on March 31.
- Renewal fee is $180, alongside 24 hours of DSPS-approved continuing education per renewal term.
- Journeyman-level work remains subject to applicable master-plumber or other authorized supervision requirements - passing the exam doesn't remove that oversight structure.
Because DSPS periodically issues 2026 plumbing-code updates, it's worth tracking those alongside the examination-reference instructions before you finalize your study materials, especially if you're prepping close to a code revision cycle.
For context on what this credential unlocks day-to-day and long-term, see WI-JP Salary Guide 2026 and Is the WI-JP Certification Worth It? Both connect the licensing mechanics above to real career outcomes.
Key Takeaway
Mark your renewal date the moment you're licensed. A four-year cycle feels distant until the 24-hour continuing education requirement sneaks up on you.
FAQ
It's two separate parts: Part 1 has 87 questions in 3 hours, and Part 2 has 120 questions in 3 hours, for a combined 207 questions across 6 hours. They are not administered as one continuous session.
Each part requires a 70% passing standard. Both parts are open book, but you still need to reach 70% on each one independently.
Pearson VUE charges $90 per part, totaling $180 for both parts. Application and credential fees through LicensE are billed separately from the exam fee itself.
Yes, but only as three-hole-punched printed notes placed inside your permitted binder alongside the required statute and code sections. Loose papers, sticky notes, and removable tabs are prohibited.
No. Once you select Pearson VUE on your application, that application cannot be reverted to a DSPS examination location, so choose your testing route carefully before submitting.
