2026 Testing Window Overview
Unlike some licensing exams that run only on fixed quarterly dates, the Michigan Journey Plumber License Exam (MI-JP) written test is administered on a rolling basis through PSI Services LLC test centers. There isn't a single "testing window" that opens and closes for everyone at once - instead, your personal testing window is defined by your LARA application approval, the PSI candidate bulletin in effect at the time, and the one-year clock that starts once your application is approved.
That said, 2026 brings one date every candidate should know: the PSI candidate bulletin covering the written exam becomes effective April 29, 2026. Bulletins spell out permitted references, content coverage, and testing-day procedures, so anyone scheduling near that date should confirm which version of the bulletin applies to their appointment.
Why the April 29, 2026 Bulletin Date Matters
The candidate bulletin is the operational rulebook for exam day: what you can bring, how the open-book format works, and how the 125-question, 180-minute written exam is structured. Because the current bulletin takes effect April 29, 2026, candidates scheduling appointments close to that date should verify they're studying and preparing materials against the correct version - particularly around approved references and document formatting rules.
This matters concretely for the open-book portion of MI-JP. Candidates are permitted to bring the 2021 Michigan Plumbing Code, the State Construction Code Act (1972 PA 230), and the Skilled Trades Regulation Act (2016 PA 407) into the testing room. Code-book chapter tabs are allowed, but highlighting, underlining, and handwritten notes are strictly prohibited. If you print statutory references from the BCC website, each one must be a separate document, bound with three staples on the left edge, with no markings or tabs - and no additional loose papers are permitted at your station.
Key Takeaway
Prep your reference books and any printed statutes according to the binding and no-markings rules well before your scheduled date - a code book with underlining or a stapled packet that doesn't meet the format can create a problem at check-in.
How PSI Scheduling Actually Works
Scheduling MI-JP isn't a matter of picking a date off a public calendar. The sequence runs like this:
- LARA approval first. You must document at least 6,000 hours of experience over at least three years as a registered plumbing apprentice under a licensed master or journey plumber, backed by notarized employer experience statements, and be at least 18 years old. LARA reviews and approves your application before PSI scheduling opens up to you.
- PSI test center booking. Once approved, you schedule your written exam appointment directly with PSI. Journey Plumber candidates test in person at a PSI test center - there is no remote-proctoring option for this exam.
- Fee payment per attempt. PSI charges $100 for each attempt of the written exam, separate from the $40 LARA initial license application fee.
If you're still working through eligibility documentation, our MI-JP Requirements 2026 guide breaks down exactly what LARA wants to see before it will clear you for scheduling.
Practical Exam Session Timing and the 30-Day Cutoff
Passing the written exam is only half of licensure. A separate BCC hands-on practical examination is also required, and it runs on its own scheduling track. The published practical session window is 10:00 a.m. to 12:30 p.m., and scheduling requests for that session must meet a 30-day cutoff - meaning last-minute requests close to your desired date typically won't be accommodated.
Because both exams draw from overlapping content, many candidates find it efficient to plan practical exam prep alongside written exam review, especially around drainage systems, vent systems, fixtures, and isometric drawing interpretation - all areas that show up in both the written test's coverage and the hands-on evaluation.
Timing Tip: Sequence Your Two Exams Deliberately
Since both the written and practical exams must be completed within the same one-year application period, don't schedule your practical so close to your written exam date that a retake attempt (if needed) would run you out of runway.
- Build in buffer time between written and practical scheduling
- Respect the 30-day practical scheduling cutoff when planning
- Track your one-year window from the date of LARA approval, not from your first exam attempt
The One-Year Application Window: The Deadline That Actually Controls Your Schedule
This is the single most important scheduling fact for MI-JP candidates: both the written and practical examinations must be passed within the same one-year application period. A passing result on either exam does not transfer to a new application if that window closes before you finish both components.
In practice, this means your real deadline pressure doesn't come from a public testing calendar - it comes from your own application clock. If you pass the written exam in month two but haven't scheduled or passed the practical by month twelve, you may need to start the application process over, re-submitting experience documentation and paying fees again.

Fees, Retakes, and Renewal Deadlines to Track Alongside Your Test Date
Scheduling MI-JP well means keeping a few recurring dollar figures and dates on your radar, not just your appointment day:
| Item | Amount / Timing |
|---|---|
| PSI written exam fee | $100 per attempt |
| LARA initial license application fee | $40 |
| Annual license renewal fee | $40, due by April 30 each year |
| Written exam format | 125 questions, 180 minutes, open-book, computer-based |
| Minimum passing score | 75% |
| Practical session window | 10:00 a.m. - 12:30 p.m. |
Once licensed, don't lose track of the annual renewal deadline of April 30 for $40 - it's separate from your exam scheduling but easy to overlook after the intensity of test prep fades. Additionally, if Michigan adopts a new plumbing code, a board-approved code-update course is required within one year of that adoption, not on a fixed annual cycle, so this is a deadline tied to code changes rather than the calendar.

Building a Domain-Based Study Timeline Around Your Test Date
Once you know your PSI appointment date, work backward using the three domains the exam actually tests: Plumbing theory, The practice of plumbing, and Knowledge of the state plumbing code, rules and regulations. A generic study calendar isn't useful here - what matters is sequencing your review so the code-heavy domain lines up with practice using your actual, tabbed reference books, since you'll rely on them open-book on test day.
Plumbing Theory Foundations
- Review hydraulics, materials, and system design principles under Domain 1
- Build familiarity with terminology used throughout the 2021 Michigan Plumbing Code
Practice of Plumbing
- Work through drainage, vent systems, fixtures, water distribution, and backflow prevention scenarios (Domain 2)
- Practice reading and interpreting isometric drawings, a recurring question format
Code, Rules, and Open-Book Navigation
- Drill Domain 3 using your tabbed code book exactly as you'll use it on exam day
- Practice locating special waste system and testing/inspection provisions quickly under time pressure
Because the exam is open-book, speed of navigation matters as much as memorization. Tabbing your code book chapters (allowed, unlike highlighting or notes) during this final stretch pays off directly during the 180-minute session. For a domain-by-domain breakdown with more topic detail, see MI-JP Exam Domains 2026: Complete Guide to All 3 Content Areas, and for a condensed pre-test refresher, the MI-JP Cheat Sheet 2026 is designed for exactly this final review window.
You can also pressure-test your pacing and open-book navigation using realistic practice questions on our MI-JP practice test platform before locking in your PSI appointment - running a few timed sets is the clearest way to know whether your six-week timeline needs adjusting.
FAQ
No. MI-JP written exams are scheduled individually through PSI once LARA approves your application. The April 29, 2026 date refers to when the current PSI candidate bulletin takes effect, not a fixed testing period.
Scheduling requests for the practical exam must meet a 30-day cutoff. The published session runs 10:00 a.m. to 12:30 p.m., so plan your request well ahead of your target date.
Both exams must be passed within the same one-year application period. A passing written score does not carry over to a new application, so you would need to reapply and retest if your window closes.
No. Journey Plumber candidates test in person at a PSI test center; there is no remote or online proctoring option for this exam.
PSI charges $100 per written exam attempt. Retakes are permitted, but each one requires a new fee and must still occur within your existing one-year application period.
