- The exam has 80 scored questions, a 210-minute limit, and requires 60 correct to pass.
- Drainage Waste and Vents is the largest domain at 30.00% of the blueprint.
- DPOR pre-approval plus $171.75 application fee and $100 PSI exam fee are both required before test day.
- Approved references may have permanent tabs and highlighting, but no loose papers or writing.
Quick Facts Snapshot
The Virginia Journeyman Plumber Exam (VA-JP) is governed by the Virginia Department of Professional and Occupational Regulation's (DPOR) Board for Contractors, Tradesmen Program, and delivered by PSI at computer-based testing centers. Every candidate should be able to recite these numbers without hesitation:
- Question count: 80 scored, multiple-choice items
- Time limit: 210 minutes
- Passing threshold: 60 correct answers
- Format: Computer-based, open-book
- Unscored items: PSI may insert 1-10 experimental questions within the same time limit
- Minimum age: 18
- Code reference: 2021 International Plumbing Code plus Virginia tradesman regulations
These are the bones of the exam. For the full explanation of how each figure was calculated and what it means for pacing, see VA-JP Passing Score 2026: Exactly What You Need to Pass.
Registration and Fee Mechanics
Before you can sit for the VA-JP, DPOR must pre-approve your application through the examination route. This is not optional paperwork - it is a gate you must clear first. The current DPOR examination-route application fee is $171.75, and once approved, you separately pay PSI a $100 exam fee to schedule your seat.
Eligibility for the examination route depends on which education-and-experience combination you meet. Virginia's published combinations span a wide range - from a related engineering bachelor's degree plus one year of practical experience, up to eight years of practical experience with no formal vocational training at all. If you are unsure which combination applies to your background, the full eligibility matrix is broken down in VA-JP Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Two Separate Payments, Two Separate Approvals
Candidates sometimes confuse the DPOR fee with the PSI fee, or assume one payment covers both. It does not.
- DPOR application fee ($171.75) - reviews your eligibility and issues pre-approval
- PSI exam fee ($100) - schedules and administers the actual test
- Both must be paid before you can sit for the exam; the application-fee step happens first

Exam Format at a Glance
The VA-JP is a computer-based, multiple-choice, open-book exam. "Open-book" does not mean easy - it means the exam is written expecting you to look up code sections and calculations quickly rather than memorize them cold. Speed with your approved references is a skill you have to practice, not something that happens naturally on test day.
With 210 minutes and up to 90 total items (80 scored plus as many as 10 unscored experimental questions), you have roughly 2.3 to 2.6 minutes per question depending on how many experimental items appear. That sounds generous until you're flipping through code references mid-test. Budgeting your time by domain weight, not just by question number, is the smarter approach - a strategy covered in more depth in VA-JP Study Guide 2026: How to Pass on Your First Attempt.
| Exam Attribute | Detail |
|---|---|
| Total scored questions | 80 |
| Possible unscored items | 1-10 (same time limit) |
| Time limit | 210 minutes |
| Passing score | 60 correct answers |
| Format | Computer-based, multiple-choice, open-book |
| Governing body | DPOR Board for Contractors, Tradesmen Program |
| Testing vendor | PSI |

Domain Breakdown Cheat Sheet
The VA-JP blueprint has 13 domains. Domain percentages are calculated from PSI's official item counts, and Drainage Waste and Vents is the single largest domain at 30.00% of the exam - meaning nearly one-third of your 80 scored questions live in that one area. That fact alone should reshape how you allocate study hours.
Domain 7: Drainage Waste and Vents (Largest Domain - 30.00%)
This is the dominant domain on the exam. Expect deep coverage of drain sizing, venting requirements, trap arm distances, and slope calculations pulled directly from the 2021 International Plumbing Code.
- Vent sizing and venting method selection
- Drainage pipe sizing based on fixture unit loads
- Slope and grade requirements for horizontal drainage piping
Domain 8: Water Supply Systems
Covers sizing and installation of potable water distribution, pressure requirements, and material approvals under Virginia's adopted code.
- Water pipe sizing methods
- Pressure-reducing and pressure-relief requirements
- Approved materials and joining methods
Domain 9: Backflow Prevention
Focuses on cross-connection control and the correct backflow prevention assembly for a given hazard level.
- Device selection by application (irrigation, boiler, fire sprinkler tie-ins)
- Installation clearance and testing requirements
Domain 13: Interceptors and Traps
Tests trap seal requirements, interceptor sizing, and where grease or oil interceptors are required by code.
- Trap seal depth and distance-to-vent limits
- Interceptor and separator sizing scenarios
The remaining domains - Standards of Practice, Standards of Conduct, Renewal and Reinstatement, Definitions, Qualification for Licensure, Revocation of Licensure, Storm Drainage Systems, Plumbing Fixtures, and General Regulations - carry smaller individual weights but collectively make up more than half the exam. Skipping them to over-focus on Drainage Waste and Vents is a common and costly mistake. A full domain-by-domain walkthrough with sample scenarios lives in the VA-JP Exam Domains 2026: Complete Guide to All 13 Content Areas.
Reference and Materials Rules
Because the VA-JP is open-book, what you can and cannot bring matters as much as what you know. Approved references may include permanent tabs, highlighting, underlining, and indexing. What is prohibited is just as important:
- Study guides
- Loose papers
- Removable tabs
- Writing directly in the references
The distinction is permanence. A tab you glued or laminated in ahead of time is fine; a sticky note or a removable flag is not. Prepare your code book weeks in advance so your tabbing system is settled - not something you're still adjusting the night before.
Key Takeaway
Build your permanent index by domain weight: tab Drainage Waste and Vents sections most heavily since it represents 30.00% of the exam, then add secondary tabs for Water Supply Systems, Backflow Prevention, and Interceptors and Traps.
Renewal and License Facts
Passing the exam is not the finish line - it's the start of a licensing cycle you have to manage. A few facts worth memorizing now, before you're staring down a renewal deadline:
- Licenses expire three years from the last day of the issuance month.
- Renewal requires three hours of Board-approved plumbing code-change continuing education.
- A tradesman license is separate from the Virginia contractor license required for work exceeding $1,000 - passing the VA-JP does not automatically authorize you to contract for larger jobs.
That last point trips up new licensees constantly. Holding a journeyman plumber license lets you perform licensed plumbing work under proper supervision or employment arrangements, but it is not the same credential as a contractor license. If you're mapping out how this license fits into a broader career path or job search, see VA-JP Jobs and VA-JP Salary Guide 2026: Complete Earnings Analysis for how employers and licensing status connect.
Final Week Review Plan
In the last week before your scheduled PSI appointment, resist adding new material. Instead, cycle through the domains in order of weight and risk. This is the only place in this cheat sheet where a structured schedule makes sense, because it's tied directly to the VA-JP blueprint rather than a generic study method.
Drainage Waste and Vents
- Re-work vent sizing and fixture unit calculations
- Confirm your permanent tabs on drainage slope tables are legible and quick to find
Water Supply Systems, Backflow Prevention, Storm Drainage Systems
- Drill pipe sizing scenarios and device-selection questions
- Cross-check backflow assembly requirements against hazard classifications
Plumbing Fixtures, Interceptors and Traps, General Regulations
- Review trap seal and interceptor sizing rules
- Skim general regulation language for exact wording candidates commonly misread
Administrative Domains
- Refresh Standards of Practice, Standards of Conduct, Renewal and Reinstatement, Definitions, Qualification for Licensure, and Revocation of Licensure
- Do a final pass through your open-book reference tabs, confirming nothing removable slipped in
For a longer-horizon version of this plan that starts weeks out instead of days out, the VA-JP Study Guide 2026: How to Pass on Your First Attempt lays out a full week-by-week structure. And if you haven't locked in a test date yet, check VA-JP Exam Dates 2026: Testing Windows, Deadlines & Scheduling before you finalize this timeline.
Once you've reviewed the material here, the fastest way to confirm readiness is running full-length timed practice sessions on the main practice test platform, where you can simulate the 210-minute, 80-question format under realistic conditions. Repeating that process on the practice site a few times before your real appointment is far more useful than re-reading notes.
