Wisconsin licenses journeyman plumbers through the Department of Safety and Professional Services under Wisconsin Statutes chapter 145 and SPS 305. The examination is given through Pearson VUE in two parts, it is open book, and the rule states the standard plainly: “A grade of 70% or greater in each part.” The code examined is SPS 381–386, the Wisconsin Plumbing Code — Wisconsin’s own state-written code. The PassProfessor Wisconsin Journeyman Plumber program prepares candidates for that examination, on that code.

What this credential certifies
A Wisconsin journeyman plumber is a licensed plumber who has completed the apprenticeship route under chapter 106 and passed the journeyman examination. The credential sits inside a structure Wisconsin candidates need to understand before they study anything else. There is no plumbing contractor license in Wisconsin. Instead, a master plumber must be in charge at all times for plumbing work offered under that responsibility. The journeyman therefore works within a master-led structure, and the journeyman credential is the examined proof that the holder can install, size, and judge plumbing work to the Wisconsin Plumbing Code without needing the code explained to them first.
That framing matters for preparation. This is not a credential earned by memorising a national model code and hoping Wisconsin follows it. Wisconsin wrote its own plumbing code, at SPS 381–386, and the examination follows Wisconsin’s text, Wisconsin’s definitions, and Wisconsin’s administrative rules in SPS 305. Candidates who arrive with habits formed under another state’s code have unlearning to do as well as learning, and the program page companion — the Wisconsin Journeyman Plumber Exam Guide — works through that route in full.

No question counts, time limits, or content outlines for this examination are published in the verified sources for this page, and none are stated here. Candidates should distrust any secondary source that prints a tidy count and a tidy duration for the Wisconsin journeyman examination as if DSPS had published them — it has not, in the material verified for this program.
The Wisconsin code: state-written, and that is the whole point
Most states examine plumbers on a model code — an edition of the International Plumbing Code or the Uniform Plumbing Code, sometimes with state amendments. Wisconsin does not. SPS 381–386 is the Wisconsin Plumbing Code, written by Wisconsin, organised as Wisconsin chose to organise it, and maintained through Wisconsin rulemaking. A candidate who prepares from a model-code text is preparing from the wrong book, however good that book is for another state.
One trap deserves naming directly. In Wisconsin commercial code usage, the letters “IPC” are defined to mean the Wisconsin code itself. A Wisconsin document that appears to invoke the IPC is not importing the International Plumbing Code as the examination basis. Read Wisconsin references on Wisconsin’s terms. The PassProfessor program is built on that discipline: SPS 381–386 supplies the substance, SPS 305 supplies the licensing and examination rules, and chapter 145 of the statutes supplies the authority above both. Nothing in the program presents the International Plumbing Code or the Uniform Plumbing Code as what Wisconsin examines.
Working to a state-written code changes study habits in practical ways. Definitions control outcomes, because Wisconsin’s defined terms can differ in scope from the familiar model-code terms a candidate learned as an apprentice in another jurisdiction. Cross-references run inside the Wisconsin chapters rather than out to a national publisher’s numbering. Amendments arrive as Wisconsin rule changes, not as a new national edition on a three-year cycle. The candidate who builds a personal index into SPS 381–386 — where definitions live, where sizing and installation duties are stated, where the code turns from general requirements to specific systems — is building exactly the map an open-book sitting rewards.
Two parts, and 70 percent in each part
The journeyman examination is given in two parts. The passing rule is quoted on this page exactly as SPS 305.09(6)(a) states it: “A grade of 70% or greater in each part”. Each part matters separately. A strong performance in one part does not carry a shortfall in the other, because the rule speaks of a grade in each part, not of an average across the examination. Preparation should therefore be balanced from the start: candidates who study only toward their stronger side are gambling that the weaker side will clear a standard it must clear on its own.
Because no published outline divides the parts for candidates in the verified material, the honest preparation strategy is breadth across the Wisconsin code as a whole, organised for fast retrieval. That is also why open-book status should not be mistaken for ease. Open book rewards the candidate who knows where a requirement lives and can confirm it quickly; it punishes the candidate who hopes to learn the code during the sitting, page by page, while the clock runs in their head even when no published limit is quoted to them beforehand.
Open book, used properly
Open book is verified for the Wisconsin journeyman examination. Used properly, it changes what memorisation is for. The candidate does not need to carry every table and every exception in memory, but does need to know the code’s structure cold: which chapter answers which kind of question, which definition governs a stem, and which requirement is general and which is specific to a system or material. In practice, that means studying with the code open from the first week, marking it lawfully and usefully, building retrieval speed alongside understanding, and practising the decision of when to look something up and when to answer from knowledge and move on.
It also means the examination can afford to ask applied questions. When the book is in the room, a sitting can test judgement — whether an installation complies, which provision controls when two seem to point different ways, what a described arrangement gets wrong — rather than only recall. Candidates should expect preparation that trains that judgement on Wisconsin fact patterns: Wisconsin definitions, Wisconsin sizing logic, Wisconsin administrative duties.
No practical, no drawing portion
The Wisconsin journeyman examination has no hands-on practical component and no drawing portion in the verified record. That is worth stating plainly because neighbouring and comparable states do impose such components, and candidates sometimes carry the assumption across state lines. Wisconsin tests this credential through its two written parts. A written preparation program can therefore address the whole of the examined event for this credential — which is not a claim any program should make where a state does require bench work, and is stated here only because Wisconsin, verified, does not.
The route, in order
The route runs in a sequence candidates should respect. First, complete the apprenticeship route under chapter 106 — that completed apprenticeship is the ladder into journeyman eligibility. Second, obtain DSPS pre-approval through LicensE; scheduling with Pearson VUE follows approval, not the other way round. Third, sit the two parts through Pearson VUE, paying the Pearson examination fee of $90 for each part, and reach a grade of 70% or greater in each part. Fourth, hold the credential on its four-year term, expiring March 31, and complete 24 hours of continuing education per term to renew. Throughout, remember the structure above the credential: no plumbing contractor license exists in Wisconsin, and a master plumber must be in charge at all times — the master tier is the next examined step for journeymen who intend to take that responsibility themselves.
Skipping the LicensE step is the most avoidable delay on the route. Candidates who contact the vendor first, or who assume an account with Pearson VUE is itself an approval, discover the order only when a sitting cannot be booked. Treat DSPS approval as the gate it is, start it early, and use the waiting time on the code.
Staying licensed: term, March 31, and 24 hours
The journeyman term is four years, expiring March 31. Twenty-four hours of continuing education are required per term for journeyman plumbers. Spread across four years, that requirement is modest; compressed into the final weeks before a March 31 expiry, it becomes a scramble that competes with work. The disciplined pattern is to earn hours steadily, keep the records with the same care as examination records, and treat renewal as a calendar obligation known years in advance rather than a surprise. The expiry date is fixed and public — no Wisconsin journeyman can claim not to have been able to foresee March 31.
Continuing education also does quiet examination work in reverse: it keeps the holder current as Wisconsin amends its own code through rulemaking. Because Wisconsin’s code is state-written, its changes arrive on Wisconsin’s schedule, and the licensed plumber who follows them through approved education is never studying a code that has quietly moved.
What makes this examination demanding
The demand is concentrated in three places. First, the code itself: state-written, self-referential, and different in organisation and detail from the model codes most generic material teaches. Second, the each-part standard: two parts, each needing 70% or greater, with no averaging to rescue an unbalanced performance. Third, the absence of published mechanics: with no verified count, duration, or outline to pace against, candidates cannot borrow a rhythm from a bulletin — they must build readiness across the whole code and trust breadth and retrieval speed. None of that makes the examination unfair. It makes it a Wisconsin examination, prepared for on Wisconsin terms or not properly prepared for at all.
What the PassProfessor program will cover
Built on the Wisconsin code, not adapted to it. PassProfessor’s catalog now includes this Wisconsin Journeyman Plumber program, composed for SPS 381–386 from the start: definitions as Wisconsin defines them, requirements as Wisconsin states them, and administrative duties under chapter 145 and SPS 305. Material written for a model-code state is not relabelled here; the delta is the program.
Each-part readiness. Practice is organised so candidates build strength across the full breadth the two parts can draw on, rather than over-investing in a favourite system. The aim is a candidate who can meet a grade of 70% or greater in each part, in the rule’s own words, without needing one part to compensate for the other.
Open-book method. The program trains code navigation as a skill in its own right — structure, indexing, and the look-up-versus-answer decision — alongside the underlying plumbing knowledge, because an open-book sitting rewards both and examines both.
Independence, stated plainly. PassProfessor is an independent preparation provider, not affiliated with the Department of Safety and Professional Services or with Pearson VUE. Completing this program confers no license and no approval; DSPS approves and licenses, and Pearson VUE delivers the examination.
