AL-MP Requirements Overview
The Alabama Master Plumber Exam (AL-MP) is administered under the authority of the Alabama Plumbers and Gas Fitters Examining Board, with Prov serving as the testing provider. Before you can sit for the exam, the Board requires you to meet specific eligibility standards, submit a complete application with the correct fees, and pass two separate examinations. This article walks through every requirement using the January 2026 Board application and the Prov bulletin dated December 15, 2025 as the governing documents.
If you're still confirming what this credential covers before diving into requirements, start with What Is AL-MP? or AL-MP Certification for foundational context.
Eligibility Criteria for In-State Applicants
For candidates already holding an Alabama certificate, the eligibility path is defined narrowly. The Board requires:
- A current, active Alabama certificate (journeyman-level or equivalent standing recognized by the Board).
- At least one year of current, verifiable journeyman work experience directly preceding the application.
- Board approval of the application itself, which is not automatic upon submission.
- Lawful-presence documentation, submitted according to the Board's required format.
Notice that the experience requirement specifies "current, verifiable" work - historical experience that isn't recent or can't be documented through employer verification will not satisfy this standard. If your journeyman experience has gaps or you've been out of active trade work, address this before submitting your application rather than after a denial.
Key Takeaway
Gather journeyman work verification and lawful-presence documents before you submit anything to the Board - incomplete applications delay your exam eligibility date.
Application Process and Fees
The Board's fee schedule separates several distinct charges, and confusing them is one of the most common mistakes among first-time applicants. Here's how the costs break down:
| Fee Type | Amount | When It Applies |
|---|---|---|
| Initial application processing fee | $50 | Submitted with your application |
| Trade examination fee | $160 | Required for the Master trade exam |
| Business Law examination fee | $100 | Required for Master applicants from January 1, 2026 |
| Initial Master certificate fee | $175 | Charged after passing both exams, before certification |
Combined, the trade exam and Business Law exam fees total $260. This is separate from the $50 application processing fee and the $175 initial certificate fee, so plan your total budget accordingly rather than assuming one flat number covers everything. For a full breakdown of every cost involved in becoming certified, see AL-MP Certification Cost 2026: Complete Pricing Breakdown.
Exam Structure: Trade Exam and Business Law
Master applicants face two distinct examinations, each with its own format, timing, and passing threshold.
Trade Examination
The core Master Plumber trade exam is computer-administered and open book, allowing approved references during testing.
- 100 questions total
- 4.17 hours allotted
- 70% passing score
- Based on 2021 IPC and 2021 IFGC references
Business Law Examination
This second, shorter exam became a requirement for Master applicants starting January 1, 2026 and tests business-side competency separate from trade knowledge.
- 40 questions total
- 2 hours allotted
- 70% passing score
- Only a failed exam must be retaken
Both exams can be scheduled at a physical test center or through eligible Examroom remote appointments, giving candidates flexibility depending on location and availability. For a deeper dive into exactly what "passing" means numerically and how scoring works, read AL-MP Passing Score 2026: Exactly What You Need to Pass. If you're weighing how challenging this combination of exams actually is, How Hard Is the AL-MP Exam? Complete Difficulty Guide 2026 breaks down the difficulty factors in detail, and AL-MP Pass Rate 2026: What the Data Shows covers what's publicly known about outcomes.
What the Trade Exam Actually Tests
The trade examination is built from 11 official domains, each with its own question allocation out of the 100 total questions. Understanding domain weight helps you prioritize study time rather than spreading effort evenly across topics that carry different exam weight.
- Domain 1: General Knowledge
- Domain 2: Drawings and Plan Reading
- Domain 3: Sizing and Design
- Domain 4: System Installation
- Domain 5: Trade Math
- Domain 6: Tools
- Domain 7: Water Heaters
- Domain 8: Roof Drain Systems
- Domain 9: Fixtures and Fittings
- Domain 10: Drain Waste and Vents
- Domain 11: Safety
Sizing and Design and System Installation carry the largest question allocations, meaning candidates who master pipe sizing calculations, fixture unit loads, and correct installation sequencing under the 2021 IPC and 2021 IFGC references will see the most direct payoff on exam day. Every domain here applies only to the trade examination - Business Law is scored and structured separately and is not part of this 11-domain breakdown.
For question-by-question guidance on each of these 11 areas, including what "must-know" topics look like inside Trade Math, Water Heaters, and Drain Waste and Vents, see the full AL-MP Exam Domains 2026: Complete Guide to All 11 Content Areas.
Approved Materials and Testing Rules
Because the trade exam is open book, understanding exactly what you're permitted to bring is itself part of meeting the requirements correctly. Approved materials include:
- Official approved references (2021 IPC and 2021 IFGC)
- Permanent tabs affixed to reference pages
- Highlighting within those references
- A simple four-function calculator
- Pen-only margin notes, provided they contain no calculations
Prohibited items are just as clearly defined: movable tabs, Post-it notes, added photocopies, and practice-test books are all barred from the testing room. Bringing a prohibited item - even accidentally, like a sticky tab instead of a permanent one - can create problems at check-in, so prepare your references well before your scheduled appointment rather than the night before.
Key Takeaway
Set up your permanent tabs and highlighting system in your 2021 IPC and IFGC references weeks before your exam date, not the day before.
After You Pass: Certification and Deadlines
Passing both examinations is not the finish line - it triggers a hard deadline. Alabama requires you to obtain your Master certificate within 90 calendar days after passing both required examinations. Missing this window can jeopardize your eligibility and force you back through parts of the process, so treat the 90-day clock as a firm requirement, not a suggestion.
The initial Master certificate fee is $175, separate from the exam fees discussed earlier. Once certified, you're recognized under the Alabama Plumbers and Gas Fitters Examining Board as a Master Plumber, opening the door to supervisory and business-owner roles that require this level of credential. If you're evaluating what that credential means for your career trajectory and earning potential, AL-MP Salary Guide 2026: Complete Earnings Analysis and Is the AL-MP Certification Worth It? Complete ROI Analysis 2026 are worth reading alongside this requirements breakdown. For information on where Master-certified plumbers typically find work, see AL-MP Jobs.
Renewal and Continuing Education
Meeting the initial requirements is only half the story - Alabama Master certificates require ongoing compliance to stay active.
- Certificates renew annually for $175, during the October 1 through December 31 window.
- Four approved continuing education hours are required annually, subject to Board exemptions.
- Plumber-only certificate holders need all four hours in plumbing topics.
- Dual plumbing/gas holders split the four required hours between both trades.
- For 2027 certification specifically, CE must be completed and submitted before November 1, 2026, with renewal completed during the October 1-December 31, 2026 window.
Missing either the CE deadline or the renewal window can lapse your certification, so mark both dates well in advance rather than relying on memory alone.
Building a Requirements-Based Prep Plan
Once your eligibility, application, and fee obligations are confirmed, the remaining work is preparation. Rather than generic study advice, your plan should map directly onto the domain weights and exam structure described above.
Heaviest Domains First
- Sizing and Design calculations using approved references
- System Installation sequencing per 2021 IPC/IFGC
Mid-Weight Domains
- Trade Math, Water Heaters, Drain Waste and Vents
- Fixtures and Fittings, Roof Drain Systems
Remaining Domains and Business Law
- General Knowledge, Drawings and Plan Reading, Tools, Safety
- Dedicated Business Law review since it's tested separately
This sequencing prioritizes the two largest-weighted domains - Sizing and Design and System Installation - early, when you have the most time to work through calculation-heavy material and reference navigation. For a structured, comprehensive walkthrough of exactly how to prepare across all 11 domains plus Business Law, see the AL-MP Study Guide 2026: How to Pass on Your First Attempt. You can also confirm current testing windows and scheduling logistics in AL-MP Exam Dates 2026: Testing Windows, Deadlines & Scheduling, and keep a condensed reference handy using the AL-MP Cheat Sheet 2026: One-Page Review of Must-Know Facts.
Practicing under realistic, timed conditions before your actual appointment is one of the most direct ways to confirm you meet the performance requirement, not just the paperwork requirement. You can build that familiarity with full-length timed sets on the AL-MP practice test platform before committing to your official exam date. Reviewing your weak domains against real practice questions on our AL-MP practice tests also helps confirm whether your reference tabbing system actually speeds you up under the 4.17-hour clock.
