Important Wisconsin distinction: The Journeyman Plumber is an individual license, not an independent contractor-business credential. Under SPS 305.93, a journeyman performs plumbing under the general supervision of a Master Plumber, Master Plumber Restricted, or Utility Contractor license holder, with scope restrictions where applicable. Do not confuse the journeyman exams with a contractor licensing exam.
The Wisconsin Journeyman Plumber license is a professional credential for people qualified to work on plumbing systems under the supervision required by state law. It marks a step beyond apprenticeship and requires familiarity with installation standards, building drainage and vent systems, fixture connections, potable water, and jobsite regulations.
Candidates entering through Wisconsin's apprenticeship route must finish a recognized plumbing apprenticeship and upload completion proof. Candidates using another pathway, such as an approved out-of-state apprenticeship, should follow the appropriate DSPS application route.
Credentialing authority: Wisconsin Department of Safety and Professional Services (DSPS).
Exam structure: Journeyman Plumber Part 1 and Part 2.
Part 1: 87 questions, 3 hours.
Part 2: 120 questions, 3 hours.
Passing score: 70%.
Format: Open book, DSPS-authorized references only.
Exam vendor: Pearson VUE computer-based sites and DSPS sites, per state instructions.
Current posted fees: $90 to Pearson and $20 to DSPS for each part; verify before scheduling.
License type: Individual Journeyman Plumber license, not a separate contractor-business license.
For review questions and guided study, see 1 Exam Prep's Wisconsin Journeyman Plumber course. Use DSPS's official licensing page for exam-authority instructions.
The journeyman route is based on apprenticeship, state authorization, two exams, and credential issuance.

Check the exam authorization: Pearson VUE and DSPS both administer trade exams, and you should follow the scheduling instructions DSPS sends after eligibility approval.
Do not mix up codes: the 2024 International Plumbing Code in the 1 Exam Prep practice package is supplementary learning material, not an officially listed Wisconsin Journeyman Plumber exam-room reference.
Wisconsin uses a two-part examination for the standard Journeyman Plumber license. The official DSPS trades schedule lists 87 questions in Part 1 and 120 in Part 2, both with a three-hour examination period.
That is 207 questions total across two separate exams. There is no reason to cram every subject into one giant practice test. Instead, prepare for each part using the state references and timed question sets.
Key study subjects include Wisconsin plumbing rules, drainage, venting, potable water systems, fixture units and plumbing fixtures, materials, cross-connection protection, pipe sizing, plan reading and isometric layouts. POWTS topics, NFPA standards and related manuals also appear in the list of authorized resources.
The DSPS page does not provide a published topic-by-topic question allocation in the materials reviewed. The study emphasis bars below are recommended practice priorities, not claimed official exam weights.
Pacing works out to about 2 minutes and 4 seconds per question for Part 1 and 90 seconds per question for Part 2. Learn your reference binder before exam day.
Use Wisconsin's official references first. Practice finding the applicable state code rule, then answer plumbing calculations without spending half the exam looking for a formula.
Wisconsin Code Navigation: Review SPS 381–387, definitions, reference organization, tables, and cross-references.
Sanitary Drainage: Practice drain sizing, fixture-unit calculations, slopes, traps, branches, and building drains.
Venting: Understand vent types, wet venting, vents for fixtures and traps, and system layout.
Water Supply and Protection: Study piping, pressure, distribution, backflow prevention, and cross-connections.
Fixtures and Equipment: Review fixture installation, water heaters, clearances, connection methods, and approved materials.
POWTS and Site Concepts: Understand onsite wastewater terminology and the component manuals named by DSPS.
Math and Isometrics: Practice conversions, flow and volume calculations, pipe sizing, and interpreting 3-D piping sketches.
Supervision and Licensing: Know Wisconsin Chapter 145, SPS 305, and journeyman practice limits.
For additional plumbing practice, explore the 1 Exam Prep Wisconsin-labeled guide and course. Its IPC examples can build general skills, but always cross-check Wisconsin state requirements.
An open-book test is only helpful when you can locate the correct rule quickly. Wisconsin's SPS 381–387 references deserve repeated practice, especially on sizing, fixtures, drainage, and vents.

Illustrative study emphasis, NOT an official DSPS question-weighting chart. DSPS publishes separate exam-part counts but no topic-by-topic weights in the pages reviewed.
Important: These bars help distribute study effort; they are not published official exam percentages or question counts. Use your actual exam authorization and the DSPS reference list to shape final preparation.
Wisconsin DSPS authorizes one code-and-notes binder plus eight additional individually listed references. Review the state requirements before testing.
| Reference | DSPS Category | Primary Study Use |
|---|---|---|
| Wisconsin Statutes Ch. 145 | In authorized binder | Plumbing laws, definitions, registration and licensing |
| Wis. Admin. Code SPS 305 | In authorized binder | Plumbing credentials and supervision |
| Wis. Admin. Code SPS 381–387 | In authorized binder | Wisconsin plumbing system design and installation code |
| Wis. Stats. Ch. 106; SPS 302; SPS 325 | In authorized binder | Apprenticeship, fees and related state rules |
| NFPA 13D (2019) | Separate listed reference | One- and two-family sprinkler systems |
| NFPA 24 (2019) | Separate listed reference | Private fire service mains and appurtenances |
| At-Grade, Holding Tank, In-Ground Soil Absorption, Mound, Pressure Distribution Manuals | Five listed component manuals | POWTS components and wastewater systems |
| Multi-Purpose Piping Systems Design Manual | Separate listed reference | Multipurpose piping-system design |
Wisconsin reference rule: Only the listed authorized materials may enter Pearson and DSPS exam locations. Notes may be printed, three-hole punched, and secured in the binder; loose pages, removable tabs and practice exams are not allowed.
2024 IPC distinction: 1 Exam Prep's Wisconsin-labeled course is based on the International Plumbing Code, but DSPS does not list that 2024 IPC book as one of its nine authorized exam-room references.
DSPS-specific rule: Unlike some other states, Wisconsin allows printed notes when they are three-hole punched and held in a proper binder. Loose materials and past or practice exams remain prohibited.
A journeyman plumber can perform plumbing activities covered by the credential, but Wisconsin requires that work to be under the general supervision of a licensed Master Plumber, Master Plumber Restricted, or Utility Contractor, as applicable. Certain supervising credentials limit the kinds of projects the journeyman may perform.
Work may involve sanitary drains, vents, fixtures, water distribution piping, approved materials, repair work, and other plumbing activities that meet current state code. Plumbing installation should follow permit, inspection, and code requirements.
This is why the user-facing phrase Journeyman Plumber Contractor Exam Prep needs a careful explanation. The journeyman credential demonstrates plumbing qualifications but should not be mistaken for an unrestricted business or independent master plumber license.
State supervision rule: See SPS 305.93 and the Wisconsin DSPS Journeyman Plumber requirements . Ask DSPS what additional registration and master-level responsibility apply before operating a plumbing business.
Choose the license that matches the work and the credential holder's actual responsibilities.
| Credential | Main Scope | Examination / Eligibility | Key Difference |
|---|---|---|---|
| Plumbing Apprentice | Learning under required oversight | Complete recognized apprenticeship | Typical entry route to journeyman eligibility |
| Journeyman Plumber | Licensed individual plumbing work | Two-part Journeyman exam or another approved route | Requires applicable general supervision |
| Master Plumber | Higher-level plumbing responsibility | Separate master-credential eligibility and exams | Different credential and broader responsibility |
| Restricted Journeyman | Limited service or appliance scope | Separate restricted application/testing | Not the standard two-part journeyman license |
| Plumbing Business / Contractor | Business activities and registration | Verify registration and responsible master arrangements | Not replaced simply by a Journeyman Plumber card |
Official DSPS timing: The department's current schedule separately lists Part 1 and Part 2. Do not treat the two together as a single three-hour exam.
Build Wisconsin-specific code knowledge first, then finish with timed two-part exam practice.
The exam can feel demanding because it has two separate parts, a broad state-specific reference list, and important plumbing calculations. You need more than worksite experience: you also need to recognize which Wisconsin rule applies to a question.
Part 1 covers 87 questions in three hours. Part 2 covers 120 in three hours. That means your pace must speed up for Part 2. Checking every question against five different books is not a winning plan.
The open-book rules can help, especially because DSPS allows correctly bound printed notes. However, a binder stuffed with uncategorized paper may slow you down instead of saving time.
Spend time on code navigation, isometric drawings, water and drain sizing, venting, and specialty reference recognition. Then test what you know without relying on answer-key memorization.
A Wisconsin-specific final review is essential. An IPC-based video or question bank can reinforce general concepts, but the state plumbing codes and official test instructions control your actual exam.
Exam-day rules: Wisconsin DSPS determines authorized references and exam materials. Always verify them shortly before your appointment.
Codebook warning: These 1 Exam Prep products are based on the 2024 IPC. They are optional supplemental materials, not a substitute for Wisconsin DSPS's authorized references. The official state code and other listed manuals should guide your final practice.
