MD-JP Exam Dates 2026: Testing Windows, Deadlines & Scheduling

How MD-JP "Exam Dates" Actually Work

If you're picturing a fixed spring or fall testing window like some professional credentials use, set that expectation aside. The Maryland Journey Plumber/Gas Fitter examination - the credential this site refers to as MD-JP - is delivered by PSI Services LLC under contract with the Maryland State Board of Plumbing, part of the Maryland Department of Labor. PSI runs computer-based testing on an ongoing, rolling basis at its test centers, which means there isn't a single published "2026 exam date" the way there might be for a once-a-year licensing board exam.

Instead, your personal exam date is determined by two things: when the Board confirms your eligibility, and when you book an available seat through PSI's scheduling system. Once your application is approved, PSI's candidate handbook (dated September 1, 2024) governs how you register and what you'll encounter on test day. If you're still mapping out the bigger picture of what this credential involves, the overview of what MD-JP is and the full requirements breakdown are good starting points before you worry about scheduling specifics.

Eligibility Timeline Before You Can Schedule

You can't schedule a seat with PSI until Maryland approves you as eligible, and that approval depends on meeting the Board's experience and training thresholds. Under ordinary eligibility rules, a candidate needs:

• Four years as a licensed apprentice
• 7,500 hours of work under a licensed Master plumber
• A current, approved 32-hour backflow-prevention device testing course

Up to 1,500 hours of approved trade-school instruction may count toward that overall experience requirement, which can shorten the field-hours clock for candidates who came up through a formal program. Because this eligibility math directly determines when you're allowed to book a test date, it's worth reviewing carefully well before you start studying content. The MD-JP requirements guide walks through each qualifying pathway in more depth.

Registering With PSI: Fees and Application Mechanics

Once you're approved, registration runs through PSI. Under the Board's July 1, 2025 fee schedule, the numbers you'll actually pay are:

These fees are separate line items - the exam fee goes to PSI to sit for the test, and the license fee goes to the Board once you've passed and applied. For a full cost breakdown, including how these figures stack up against the time investment of training, see the MD-JP certification cost guide.

All applications now go through the Board's online system, a change that took effect March 31, 2025. If you're used to mailing in paperwork for other trade licenses, this is one area where MD-JP has modernized faster than some neighboring processes - plan to have scanned documentation ready rather than originals in an envelope.

What to Expect on Test Day: Format and Timing

The base Journey Plumber/Gas Fitter examination consists of 100 scored questions delivered in a computer-based, multiple-choice format, with 240 minutes allotted. PSI may also insert five to ten additional, unscored experimental questions used for future exam development - these come with extra time added outside your base 240-minute allowance, so don't panic if your total session feels longer than expected.

The passing score is 70%, a figure confirmed both in the PSI candidate bulletin and in COMAR 09.20.02.03. If you want the exact mechanics of how that score is calculated and what it means for how many questions you can miss, the passing score breakdown covers it in detail.

One detail worth flagging before you buy reference books: the PSI bulletin's reference list points to the 2018 IPC and 2018 IFGC, but the Board's June 18, 2026 meeting minutes discuss a 2024-code examination update. Reference editions can shift, so confirm the current assigned editions directly with PSI before you invest in code books rather than assuming last year's list still applies.

The Retest Window If You Don't Pass

If you don't clear the 70% threshold on your first attempt, Maryland's retest rule allows you to sit again once every 30 days. That's a meaningful scheduling constraint: it's not an unlimited-retake system, and it's not a long cooling-off period either. Thirty days is roughly enough time to target your weakest domains without so much time passing that you lose momentum on material you already knew.

The Board's June 18, 2026 minutes reported a Journey Plumber/Gas Fitter pass rate of 43% for that month's cohort - 27 of 63 candidates passing. That's a single monthly snapshot, not an annual or first-attempt-only figure, but it's a useful reminder that a meaningful share of candidates need more than one sitting. If you want a deeper look at what that number does and doesn't tell you, read the MD-JP pass rate analysis. For a broader sense of where the difficulty actually lies, the exam difficulty guide is a useful companion read while you're planning a retest strategy.

License Application Deadline After Passing

Passing the exam is not the finish line - you must apply for your license within one year of the date you passed. Miss that window and you may find yourself needing to retest before you can move forward, which turns a scheduling oversight into a real setback after months of preparation.

Build this deadline into your calendar the same day you get your passing result. It's a simple administrative step, but it's also one of the most common ways candidates lose ground unnecessarily - not because the material was hard, but because the paperwork clock ran out.

Renewal Calendar and CE Rules

Once licensed, Maryland's ordinary Journey plumber license operates on a biennial renewal cycle, and there is no routine continuing-education requirement attached to that ordinary renewal. That's a distinction worth noting if you're comparing MD-JP to trades or credentials that mandate annual CE hours - plumbing inspector licensure is a separate track with its own CE obligations, but the standard Journey license does not carry that burden.

This matters for long-term scheduling: once you're through the exam and licensing process, your calendar obligations shrink to renewal fee payments every two years rather than an ongoing cycle of coursework deadlines.

Domain Weighting and Why It Affects Your Schedule

Understanding the exam's content structure helps you decide how to allocate your remaining prep time before whatever date you book with PSI. The exam draws from nine official domains, and they are not weighted equally. Based on the official allocations across the 100 scored questions, Gas Appliances and Piping is the largest domain, followed by Drain, Waste, and Vent Systems and Backflow Prevention.

The remaining six domains - Plumbing Fundamentals and Safety, Materials, Uses, and Specifications, Traps, Interceptors, and Backwater Valves, Plumbing Fixtures, Fixture Fittings, and Plumbing Appliances, Water Supply Systems, and Plumbing Mathematics - round out the remaining question count. For a complete breakdown of all nine areas with study priorities for each, the full domains guide is the most detailed resource on this site.

A Study Timeline Built Around the Domains

Once you have a tentative PSI date in mind, working backward with a domain-weighted schedule beats reviewing topics in random order. Here's a sample structure you can adapt to however many weeks you have before your booked date:

If you want a structured, week-by-week walkthrough with more detail on pacing and resource selection, the MD-JP study guide expands on this approach, and the one-page cheat sheet is useful for the final-week review pass. You can also run realistic timed sessions on our MD-JP practice test platform to get comfortable with the 240-minute pacing before your actual PSI appointment.

WSSC and Baltimore County Scheduling Notes

Not every plumbing jurisdiction in Maryland routes through the same licensing structure. WSSC (Washington Suburban Sanitary Commission) and Baltimore County maintain their own separate licensing arrangements outside the standard state Board process. If you plan to work primarily within those jurisdictions, verify their specific requirements alongside the statewide MD-JP process, since scheduling and documentation steps may differ from what applies to the standard Journey Plumber/Gas Fitter license described here.

This distinction is also worth understanding if you're evaluating career direction more broadly - the MD-JP jobs overview and salary guide touch on how licensing jurisdiction can affect where you're eligible to work once you're licensed.
