What TSBPE Actually Publishes About Pass Rates
If you searched for this article hoping to find an official Texas State Board of Plumbing Examiners (TSBPE) pass-rate percentage for the Journeyman Plumber License Exam, here's the honest answer: TSBPE and Pearson VUE, which administers the computer-based written exam, do not publish a public pass-rate statistic broken down by year, region, or candidate type. There is no verified "2026 pass rate" number floating around that you should trust if you see one quoted on a forum or a competitor's blog.
That absence of a published number doesn't mean the pass/fail dynamics are a mystery, though. TSBPE is very transparent about the mechanics that actually determine whether a candidate passes: the scoring threshold, the question count, the time limit, the retake waiting periods, and the reference materials the exam draws from. Those mechanics tell you far more about your real odds than a single aggregate percentage ever could, because your outcome depends on your preparation against a fixed, known standard - not on how a statewide average happened to land in a given quarter.
Why Exam Structure Matters More Than a Headline Number
Even if a precise pass-rate percentage existed, it would tell you very little about your individual chances. What matters is understanding how the exam is built and where candidates typically lose points. The JP written exam is closed book and draws from the 2018 IPC combined with either the 2018 IFGC or the 2018 UPC, plus Texas plumbing license law and board rules. That combination is the actual "data set" you need to study - not a rumor about how many people passed last quarter.
Apprentice-to-Journeyman candidates face an additional layer: six practical items completed in 4 hours, in addition to the written portion. Eligible Tradesman Plumber-Limited licensees, by contrast, take only the written component. That structural difference alone means "the JP pass rate" isn't even a single number conceptually - it's really two different testing paths with different failure points, which is one more reason a single published percentage would be misleading even if it existed.
Key Takeaway
Stop searching for a magic pass-rate percentage and instead study the exact scoring rule: 70% of 100 questions in 2 hours, closed book, from the 2018 IPC/IFGC or UPC plus Texas law.
Which Domains Decide Whether You Pass
Because TSBPE doesn't release item-level analytics, the most reliable way to estimate where candidates struggle is to look at the ten content domains the written exam covers and think honestly about which ones require memorization versus applied code interpretation. For a full breakdown of each area, the JP Exam Domains 2026: Complete Guide to All 10 Content Areas is worth reading alongside this article.
Domain 1: Plumbing License Law and Board Rules
Candidates who skip Texas-specific statute and board rule study often underestimate how many questions test administrative and legal knowledge rather than pipe sizing.
- Know licensing categories, renewal cycles, and enforcement authority
Domain 6: Water Supply and Distribution
This domain blends math (pipe sizing, pressure loss) with code lookup speed, making it one of the more time-intensive domains under exam conditions.
- Practice locating sizing tables quickly under a timer
Domain 10: Fuel Gas or Fuel Piping
Because this domain pulls from a separate code book (IFGC or UPC fuel gas provisions depending on your path), it's easy to under-study if you're focused mainly on the IPC.
- Confirm which fuel gas reference applies to your exam version
Domains like Definitions, Traps, and Vents tend to reward straightforward memorization, while Sanitary Drainage, Water Heaters, and General Regulations or General Requirements require you to apply code logic to scenario-style questions rather than recall isolated facts. A candidate who treats all ten domains as equally "memorize-and-move-on" often finds the applied-logic questions eat up disproportionate time on exam day.
The Retake Rules That Punish Underprepared Candidates
One of the most concrete pieces of "pass rate data" TSBPE does publish isn't a percentage - it's the retake policy, and it's arguably more useful. Initial authorization permits up to five attempts within one year. After a failed attempt, candidates face waiting periods of 30, 60, and 90 days before subsequent attempts. If you fail multiple times in a row, those waiting periods stack up and can consume most of your one-year authorization window.
| Attempt | Waiting Period Before Next Attempt |
|---|---|
| 1st failure | 30 days |
| 2nd failure | 60 days |
| 3rd failure | 90 days |
| 4th-5th attempt | Must occur within the one-year authorization window |
This structure means the practical "pass rate" that matters to you isn't a statewide average - it's whether you pass within your first one or two attempts before the waiting periods start compressing your timeline. Candidates who understand this upfront tend to over-prepare for attempt one rather than treat it as a low-stakes trial run.
Written Exam vs. Practical: Two Different Failure Points
For Apprentice-to-Journeyman candidates, passing the written exam is only half the requirement. The practical exam - six items completed in 4 hours - must be passed within one year of passing the written exam. This creates a second, distinct point where candidates can stall out even after clearing the written hurdle. Tradesman Plumber-Limited licensees who are eligible to take only the written portion skip this step entirely, which is another reason a single blended pass rate wouldn't accurately represent either group.

Complete Difficulty Guide 2026 and Is the JP Certification Worth It? Complete ROI Analysis 2026 both dig into that decision in more depth than a pass-rate article can.
A Domain-Based Prep Timeline That Reflects the Real Test
Because there's no published pass-rate curve to reverse-engineer, the smartest use of your prep time is to weight your schedule toward the domains that combine high question exposure with applied-logic difficulty, rather than spreading effort evenly across all ten. A domain-anchored timeline, paired with timed practice questions on the main practice test platform, gives you a much better read on your readiness than any generic pass-rate figure would.
Law, Rules, and Definitions
- Build the vocabulary foundation the rest of the exam depends on
- Review Texas Plumbing License Law and board rules line by line
Water Supply, Sanitary Drainage, and Vents
- Drill pipe sizing and pressure calculations under a timer
- Practice tracing drain-waste-vent systems from fixture to stack
Water Heaters, Traps, and Fixtures
- Focus on installation clearances, venting, and code-specific requirements
Fuel Gas Piping and Full-Length Timed Runs
- Confirm your correct fuel gas reference (IFGC or UPC path)
- Take full 100-question, 2-hour practice runs at exam pace

The Real Cost of Failing and Retesting
Pass-rate discussions often skip the financial angle, but the fee structure makes retesting a real cost consideration, not just a scheduling annoyance. The TSBPE examination application fee is $40, the written exam fee is $68.50, and the practical exam fee is $40 when required. Failing the written exam doesn't just cost you 30, 60, or 90 days - it likely means paying the exam fee again for each retake, on top of the time you'll spend re-preparing.
- Application fee: $40
- Written exam fee: $68.50
- Practical exam fee (when required): $40
- Initial license fee: $40
A full breakdown of every fee in the licensing process, including how they stack across an Apprentice-to-Journeyman path versus a Tradesman Plumber-Limited path, is available in JP Certification Cost 2026: Complete Pricing Breakdown. If you're weighing the exam against your experience hours and training requirements, JP Requirements 2026: Eligibility, Prerequisites & How to Qualify lays out the 8,000-hour experience threshold and the 48-hour training course requirement in full.
Key Takeaway
Treat the $68.50 written exam fee as a one-shot cost you want to avoid paying twice - thorough domain-by-domain prep is cheaper than a second attempt.
It's also worth remembering who's on the other side of this exam once you pass it. Licensed journeyman plumbers are hired by residential and commercial plumbing contractors, mechanical contractors, and municipal utility departments across Texas, and the license itself - not a self-reported pass rate - is what employers verify. If you're exploring what comes after licensure, JP Jobs and JP Salary Guide 2026: Complete Earnings Analysis cover the employment side in more detail, and practicing with realistic questions on JP Exam Prep's practice platform is one of the most direct ways to close the gap between where you are now and the 70% threshold.
Frequently Asked Questions
No. Neither TSBPE nor Pearson VUE publishes a public pass-rate percentage for the Journeyman Plumber written exam. The reliable, verifiable data points are the scoring rule (70% of 100 questions in 2 hours) and the retake policy.
You need 70% on the 100-question, multiple-choice written exam, completed within a 2-hour time limit. For more detail on how the score is calculated, see JP Passing Score 2026: Exactly What You Need to Pass.
