MA-JP Passing Score 2026: Exactly What You Need to Pass

The Actual Passing Score for MA-JP

If you're preparing for the Massachusetts Journeyman Plumber License Examination, the passing score question has a precise, unambiguous answer: you need at least 70% on Part I Written and at least 70% on Part II Practical. These are two independent, closed-book, computer-based tests administered through PSI Services LLC after your application has been approved by the Massachusetts Board of State Examiners of Plumbers and Gas Fitters, Division of Occupational Licensure.

There is no single combined score for the "MA-JP exam" as a whole. Candidates sometimes assume that scoring high on one part can offset a weaker performance on the other - it can't. Each part stands on its own, and each has its own 70% bar to clear. This structure has real consequences for how you should prepare, which we'll walk through below. For a broader orientation to what the exam covers before diving into scoring mechanics, the MA-JP Study Guide 2026: How to Pass on Your First Attempt is a useful starting point.

Why Two Separate Scores Matter More Than One Combined Score

The "Exam" line item on your PSI scheduling record combines both parts into a total of 120 questions across 320 minutes, but that combined figure is administrative bookkeeping - it does not represent how you're graded. Scores are not pooled or averaged to determine whether you pass. This matters practically in three ways:

• You can't "bank" a strong score. A 95% on Part I Written won't rescue a 60% on Part II Practical. You still fail Part II and must retake it.
• Failure isolates the damage. If you fail only one part, you don't have to sit through both parts again - only the failed portion needs a retest.
• Preparation should be part-specific. Because the two parts test different skills (recall-based regulatory knowledge versus applied practical calculation), treating them as one undifferentiated "exam" during study is a mistake many candidates make.

This distinction is one reason candidates researching How Hard Is the MA-JP Exam? Complete Difficulty Guide 2026 often discover that difficulty isn't uniform - some domains are dense with regulatory detail, others demand hands-on isometric reasoning.

How the 70% Threshold Plays Out Across All 16 Domains

Part I Written spans Domains 1 through 12, with the following official question allocations:

Part II Practical covers Domains 13 through 16:

Notice that Gas Piping, Equipment, and Appliances is the largest written domain at 21 questions, and Isometric Analysis is the largest practical domain at 20 questions. Together these two domains alone represent a huge share of your total point opportunity - nearly half of Part II's questions come from isometric work alone. For a full walkthrough of what each of the 16 domains actually tests, see the MA-JP Exam Domains 2026: Complete Guide to All 16 Content Areas.

Question Format and What "Passing" Actually Requires

Both parts of the MA-JP exam are closed-book and computer-based, administered by PSI. Nothing beyond a permitted calculator is allowed at the workstation - no printed code books, no notes. The allowed calculator must be nonprogrammable, nonprinting, silent, battery-operated, and free of alphabetic keys. This closed-book format is a critical planning point: unlike some trade exams that permit code-book lookups, MA-JP requires you to have memorized or internalized code references well enough to answer from recall under timed conditions.

Part I gives you 160 minutes for 80 questions - an average of two minutes per question. Part II gives you 160 minutes for 40 questions, or roughly four minutes per question, which reflects the more analytical, drawing-based nature of the practical section. Passing each part means answering enough questions correctly to reach that 70% mark within your allotted domain-weighted question set - not simply finishing the test.

Retake Rules, Fees, and the One-Year Clock

If you fail a part, you don't start over from scratch. Only the failed part needs to be retaken, at the standard examination/retest fee of $80. This is separate from the $31 application fee and the $52 initial journeyman license fee you pay once you actually pass and apply for licensure.

PSI enforces two time windows candidates should track carefully:

• A 12-month examination window from the date your application is approved, within which you must sit for and complete testing.
• One-year validity for passing scores - if you pass one part but fail the other, you must pass the remaining part within that same window, or your passing score may expire and require retesting.

For a complete accounting of every fee in the process - application, testing, retesting, and licensing - see the MA-JP Certification Cost 2026: Complete Pricing Breakdown. And if you haven't yet confirmed you meet the eligibility path (6,800 hours of supervised apprentice work and 550 hours of approved theory over at least four years under 248 CMR 11.02), review the MA-JP Requirements 2026: Eligibility, Prerequisites & How to Qualify before you schedule anything through eLIPSE.

Doing the Scoring Math for Each Part

Because each part is scored independently at a 70% threshold, it's worth translating that percentage into actual question counts so you know exactly what margin you're working with.

• Part I Written (80 questions): 70% means correctly answering roughly 56 of 80 questions. That leaves roughly 24 questions of room for error - but remember, those errors aren't evenly distributed across domains, so missing too many Gas Piping or Drain, Waste, and Vent questions (the two heaviest written domains) puts disproportionate pressure on the rest of the test.
• Part II Practical (40 questions): 70% means correctly answering roughly 28 of 40 questions. With Isometric Analysis alone accounting for 20 of those 40 questions, weakness in reading isometric drawings can single-handedly threaten your Part II pass.

This is not a case where every domain carries equal risk. A candidate who is strong across Domains 4, 5, 6, 7, 9, and 12 (each worth only 2-3 questions) but weak in Domain 2 or Domain 10 is in a much more precarious position than the reverse. Score planning should follow question weight, not alphabetical order or personal comfort level.

Where to Focus Study Time Given the Scoring Structure

Given that passing is a per-part threshold rather than an overall average, the highest-leverage move is to allocate study time in proportion to each domain's question count - and to treat Part I and Part II prep as genuinely separate tracks, since a closed-book recall test and a drawing-interpretation test reward different skills.

This week-by-week structure follows a simple spaced-repetition logic: front-load the domains with the largest point value, then circle back to lower-weight material once the heavy hitters are solid. If you want a condensed reference to keep nearby during final review, the MA-JP Cheat Sheet 2026: One-Page Review of Must-Know Facts is built around this same domain-weight logic.
