- General Knowledge (10 questions) and Sizing and Design (9 questions) carry the most weight.
- Total cost to sit and certify runs $235: $110 exam fee plus $50 processing and $75 certificate.
- Eligibility requires two years of current apprentice experience or a Board-approved training program.
Understanding the AL-JP Exam
The Alabama Journeyman Plumber Exam (AL-JP) is administered by the Alabama Plumbers and Gas Fitters Examining Board and delivered through the testing vendor Prov, Inc. Passing it earns you the official Journeyman Plumber (JP) certificate - the credential that lets you legally perform journeyman-level plumbing work in Alabama without direct master-plumber supervision on every task.
This is not a generic multi-state trade test. It is built around Alabama's own bulletin (currently dated December 15, 2025), Alabama-specific law citations, and a defined set of reference materials. If you've searched for background on the credential itself, our companion pieces on What Is AL-JP? and AL-JP Meaning cover the naming and scope in more depth. This guide focuses purely on how to prepare and pass.
Registration, Eligibility, and Fees
Before you can schedule a seat, you need to satisfy the Board's eligibility path: two years of current apprentice-plumber experience, or completion of a Board-approved apprentice training program, along with required experience documentation and proof of lawful presence. For a full walkthrough of what documentation the Board expects, see AL-JP Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Once approved, the fee structure is straightforward but worth budgeting for in full:
| Charge | Amount | When Paid |
|---|---|---|
| Exam fee (nonrefundable, paid to the Board) | $110 | At registration |
| Initial processing | $50 | After passing |
| Certificate issuance | $75 | After passing |
| Total exam + initial certification | $235 | Before any books or training |
That $235 figure covers only the examination and initial-certification charges - it doesn't include study materials, reference books, or any prep courses you choose to take. For a line-by-line breakdown of every dollar involved, including annual renewal costs, read AL-JP Certification Cost 2026: Complete Pricing Breakdown.
Key Takeaway
The $110 exam fee is nonrefundable, so don't schedule your seat until you've genuinely reviewed the domain breakdown and feel ready - rescheduling a bad attempt costs you money twice.
Exam Format and Test-Day Rules
The current AL-JP profile is fixed and published by Prov: 75 questions, a time limit of 2.92 hours, delivered as computer-based multiple choice, and open book. You need a 70% score to pass. That means roughly 53 correct answers out of 75 - leaving very little margin for guessing your way through unfamiliar sizing or code questions.
Prov gives you two ways to sit the exam: an in-person appointment at a test center, or at-home Examroom proctoring. Whichever you choose, the same tool rules apply:
- A four-function calculator only - no scientific or graphing calculators
- Highlighting of your approved references is permitted
- Permanent tabs may be placed in your code books and reference texts ahead of time
- Pen-only marginal notes are allowed, but you cannot write calculations in the margins
Two deadlines matter just as much as the exam itself. Your Prov eligibility to schedule lasts only 30 days, so don't get approved and then sit on it. And once you pass, you must obtain your certificate within 90 calendar days - miss that window and you'll be dealing with the Board to sort out next steps.

The 12 AL-JP Domains
AL-JP content is organized into twelve domains, and they are not weighted evenly. Knowing which domains carry the most questions should directly shape how you allocate study hours. For the full breakdown of every domain with sample topics, see AL-JP Exam Domains 2026: Complete Guide to All 12 Content Areas. Here's the short version:
Domain 1: General Knowledge (10 of 75 questions - the largest domain)
Covers broad code familiarity and foundational plumbing principles pulled from the 2021 IPC and general trade knowledge. Because it's the single biggest domain, weak preparation here has an outsized effect on your score.
- General code structure and terminology
- Broad application questions that cross multiple systems
Domain 5: Sizing and Design (9 of 75 questions)
The second-largest domain, focused on pipe sizing, fixture unit calculations, and design decisions that require applying tables from your references rather than memorized answers.
- Fixture unit and drainage sizing tables
- Water supply and gas pipe sizing methods
Domain 12: Alabama Plumbing and Gas Law (5 questions)
Pulled directly from the 2022 Code of Alabama Title 34 Chapter 37 and Administrative Code Chapter 720. These questions are Alabama-specific and won't appear in generic multi-state plumbing prep.
- Board authority and licensing law
- Administrative code provisions unique to Alabama
The remaining domains - Drawings and Plan Reading, Trade Math, Tools, Fixtures and Fittings, Drain Waste and Vents, Roof Drain Systems, System Installation, Water Heaters, and Safety - round out the other 51 questions. None of them should be ignored, but General Knowledge and Sizing and Design deserve the most concentrated study blocks simply because of their question count. If you're trying to gauge overall difficulty before committing to a study schedule, How Hard Is the AL-JP Exam? Complete Difficulty Guide 2026 breaks down where most candidates struggle.
Building a Domain-Focused Study Plan
Rather than studying domains in the order they're listed, sequence your prep by question weight and difficulty. A six-week plan built around AL-JP's own domain allocations looks like this:
General Knowledge & Trade Math
- Work through 2021 IPC sections tied to general knowledge questions
- Drill calculations from Mathematics for Plumbers and Pipefitters, 8th edition
- Place permanent tabs on frequently-referenced code sections now, not the night before
Sizing and Design
- Practice fixture-unit and pipe-sizing table lookups until they're fast, not just correct
- Time yourself - sizing questions eat clock time in a 2.92-hour exam
Drain Waste and Vents, Water Heaters, Fixtures and Fittings
- Cross-reference Modern Plumbing, 8th edition for installation diagrams
- Review the 2021 IFGC sections relevant to gas-fired water heaters
Alabama Plumbing and Gas Law, Safety, Tools
- Read Title 34 Chapter 37 and Administrative Code Chapter 720 in full at least once
- Don't skip this domain just because it's only 5 questions - it's the domain generic prep never covers
Drawings and Plan Reading, System Installation, Roof Drain Systems, Full Review
- Run full-length timed practice sets under open-book, tabbed-reference conditions
- Simulate the actual 2.92-hour window so pacing feels familiar on test day
For structured practice questions organized by these same domains, our AL-JP practice test platform lets you drill weak areas without waiting for a live exam attempt to find them. If you'd rather see the whole prep roadmap laid out as a single reference, AL-JP Study Guide 2026: How to Pass on Your First Attempt and the condensed AL-JP Cheat Sheet 2026: One-Page Review of Must-Know Facts are both built to complement this timeline.
Approved References You Should Actually Own
Because AL-JP is open book, your reference materials are part of your test strategy, not just your study strategy. The current bulletin lists these as your source material:
- 2021 IPC (International Plumbing Code)
- 2021 IFGC (International Fuel Gas Code)
- Mathematics for Plumbers and Pipefitters, 8th edition
- Modern Plumbing, 8th edition
- 2022 Code of Alabama, Title 34, Chapter 37
- Administrative Code Chapter 720, 2018
Buy physical or approved digital copies of each and tab them well before test day. Prov permits permanent tabs and highlighting, so a well-organized code book can save you several minutes per question during the exam - time that matters when you're answering 75 questions in under three hours.
Key Takeaway
Tab your 2021 IPC and 2021 IFGC by topic (sizing tables, venting, fuel gas piping) rather than by chapter number - you'll navigate faster under time pressure than if you're hunting by section title.
What Happens After You Pass
Passing is only half the process. You then have 90 calendar days to obtain your certificate, and the total cost of doing so - $50 initial processing plus $75 for the certificate itself - comes due at that stage. Miss the window and you risk needing to re-engage with the Board's process.
Once issued, your Journeyman Plumber certificate expires every December 31 and must be renewed annually for $75. Renewal also requires four approved continuing education hours completed before November 1 of the year preceding renewal, though the Board allows an exemption during your initial certification year and a documented exemption for licensees age 65 and older.
Mark these dates now, before you even sit for the exam, so certification maintenance doesn't catch you off guard a year from now.
Why This Certificate Matters in Alabama
The Journeyman Plumber certificate is what allows licensed plumbing contractors, mechanical contractors, and municipal utilities across Alabama to hire you for journeyman-level work rather than apprentice-level tasks. If you're weighing whether the time and $235 in exam and certification costs are worth it relative to what apprentice wages pay, Is the AL-JP Certification Worth It? Complete ROI Analysis 2026 and AL-JP Salary Guide 2026: Complete Earnings Analysis dig into that comparison in detail. And if you're further along and researching where certified journeyman plumbers actually get hired in the state, AL-JP Jobs and AL-JP Training cover those angles specifically.
Whatever stage you're at, running through timed, domain-organized questions on our AL-JP practice platform before test day is the most direct way to convert study hours into exam-day confidence - especially for the heavily-weighted General Knowledge and Sizing and Design domains.
