5 Plumbing License Practice Test Options (Free + Paid)
Passing your journeyman or master plumber exam comes down to preparation, and a solid plumbing license practice test is one of the best ways to get ready. These exams cover everything from code requirements to practical scenarios, and walking in without practice puts you at a serious disadvantage.
At PlumbingJobs.com, we see it every day: licensed plumbers land better positions with higher pay. Employers across the country specifically seek out candidates who’ve earned their credentials, which means your license directly impacts your career options.
The good news? You don’t have to guess what’s on the exam. Several resources exist to help you study, some free, some paid, each with different strengths depending on your learning style and budget. Below, we’ve rounded up five practice test options that can help you walk into your licensing exam with confidence.
1. Tests.com plumbing practice test
Tests.com offers a comprehensive free practice test that mirrors the format of actual licensing exams. You get access to multiple-choice questions covering code requirements, fixtures, water supply systems, and drainage fundamentals, all without creating an account or paying a fee.
What you get
The platform provides 100 practice questions divided into sections that match real exam categories. Each question comes with immediate feedback and explanations that help you understand why an answer is correct or incorrect. You can retake the test as many times as needed to reinforce weak areas.
“Free practice tests give you a risk-free way to gauge your readiness before investing in paid materials.”
Best for
This resource works best for entry-level candidates preparing for journeyman exams. If you’re looking for a baseline assessment or just starting your study routine, the straightforward format helps you identify knowledge gaps without overwhelming you with advanced scenarios.
Cost and access
Tests.com operates entirely free with no subscription required. You simply visit the site, select the plumbing practice test, and start answering questions. The mobile-friendly interface lets you study during breaks or commute time.
Strengths and limitations
The main strength is zero cost combined with solid foundational coverage. However, the question pool stays relatively static, meaning repeated use can lead to memorization rather than true learning. Advanced topics and state-specific code variations get minimal attention.
How to use it in your study plan
Start with this plumbing license practice test to establish your baseline score. Take it once without studying to see where you stand, then revisit it weekly as you work through textbooks or courses. Use your incorrect answers to guide which topics need extra review time.
2. Contractor Practice Exam plumbing practice test
Contractor Practice Exam delivers a structured plumbing license practice test focused on state-specific code requirements and exam formats. Their question bank pulls from actual licensing exams, giving you exposure to the terminology and scenarios you’ll face on test day.

What you get
You receive access to timed practice exams that simulate real testing conditions, with questions covering the International Plumbing Code and your state’s amendments. The platform tracks your progress over time and highlights topics where you consistently score below passing thresholds.
Best for
This option suits journeyman candidates preparing for state exams with strict code enforcement. If your state follows IPC standards closely, the targeted question sets align well with what examiners actually test.
Cost and access
Contractor Practice Exam charges $49 for three months of full access. You can purchase individual exam categories separately for less, but the bundle offers better value for comprehensive preparation.
Strengths and limitations
The main advantage is state-specific customization that matches your jurisdiction’s requirements. The limitation comes from a smaller question pool compared to larger platforms, which can lead to repetition during extended study periods.
“State-specific practice tests reduce wasted study time on codes your exam won’t cover.”
How to use it in your study plan
Use this resource during your final month of preparation after you’ve built foundational knowledge. Take full-length timed exams weekly to build stamina and identify any remaining weak areas before your actual test date.
3. PSI Online Store journeyman plumber practice test
PSI Services operates as the official testing provider for many state licensing boards, and their online store sells the actual practice materials used to prepare candidates for exams they administer. You get direct access to resources built by the organization that writes and scores your official test.
What you get
The PSI Online Store provides a downloadable PDF practice exam containing questions pulled from their existing question banks. Each purchase includes detailed answer keys that explain the reasoning behind correct responses, helping you understand the code sections and calculations involved.
Best for
This plumbing license practice test works best for candidates in PSI-administered states who want to familiarize themselves with the exact testing format they’ll encounter. If your state contracts with PSI, this resource gives you the closest match to your actual exam experience.
Cost and access
PSI charges $25 per practice exam with immediate digital delivery after purchase. You download the PDF once and can print or reference it as many times as needed without additional fees.
“Practicing with the same organization that administers your exam removes uncertainty about question format.”
Strengths and limitations
The primary strength is authenticity since PSI creates the actual exams. However, the static PDF format lacks interactive features like timed tests or progress tracking that other platforms offer.
How to use it in your study plan
Purchase this resource two weeks before your scheduled exam date. Complete the practice test under timed conditions, then review every missed question thoroughly to identify final gaps in your knowledge.
4. The Plumbing Academy practice tests

Cost and access
The Plumbing Academy charges $99 for six months of full platform access. You can cancel anytime, and the mobile app lets you study offline after downloading content.
“Adaptive practice tests focus your study time where you need it most.”
Strengths and limitations
The video explanations provide clarity that text-only answers can’t match. However, the higher cost compared to basic practice tests may not fit every budget, and some users report that question pools feel smaller than advertised.
How to use it in your study plan

“Free practice tests let you assess readiness before investing in premium materials.”
Strengths and limitations
The zero-cost access represents the biggest advantage for budget-conscious candidates. However, the limited question pool means you’ll see repeat questions quickly, and the lack of state-specific customization may not match your jurisdiction’s exact exam format.
How to use it in your study plan
Use this test as a weekly checkpoint to track improvement throughout your preparation. Take it every seven days and aim for consistent score increases, treating repeated exposure as reinforcement rather than memorization.
