- The TDLR exam fee is $64 per attempt, separate from the $20 initial license application fee.
- Annual license renewal costs $20 plus four TDLR-approved continuing education hours.
- FY2025 data shows 767 of 1,098 attempts failed, so budgeting for at least one retake is realistic.
- Bring your own softbound NEC with permanent, publisher-made tabs - homemade tabs are prohibited and can force a costly reschedule.
The Complete TX-RW Fee Breakdown
Unlike certifications with bundled pricing, the Texas Residential Wireman Electrician License Exam (TX-RW) separates the licensing process into distinct fees charged by two different entities: the Texas Department of Licensing and Regulation (TDLR) and PSI Services LLC, the third-party administrator that runs the actual test. Understanding this split matters because candidates often assume one fee covers everything - it doesn't.
- Examination fee: $64 per attempt, paid to PSI when you schedule your test.
- Initial license application fee: $20, paid to TDLR when you apply for the Residential Wireman license.
- Renewal fee: $20 annually, plus four hours of approved continuing education.
That means the baseline cost to sit for the exam and obtain your license the first time you pass is $84 in state and testing fees combined - assuming you pass on your first attempt. If you don't, the $64 exam fee is charged again for every subsequent attempt, while the $20 application fee is a one-time cost tied to the license itself, not the exam.
Hidden and Indirect Costs to Budget For
The advertised fees only tell part of the story. Several indirect costs shape the real price of earning your TX-RW license, and most candidates underestimate them.
The NEC Code Book
The exam is open book, but only under strict conditions. You must bring your own softbound National Electrical Code book with any notes, highlighting, or underlining completed before the test date. Permanent index tabs are allowed only if manufactured or provided by the NEC publisher - homemade tabs, third-party tab kits, added sheets, the NEC Handbook, and loose-leaf, spiral-bound, or ring-bound editions are all prohibited. If you show up with a non-compliant book, you risk being turned away and losing your $64 exam fee entirely.
With PSI's bulletin update effective July 9, 2026, exam references shift to the NEC 2026 edition starting September 1, 2026. Candidates testing near that transition date should confirm which edition their scheduled exam uses before buying a book, since purchasing the wrong edition means paying twice.
Documented Experience Verification
Before you can even apply, you need 4,000 documented on-the-job hours supervised by a Texas-licensed Master Electrician or Residential Wireman, or completion of a TDLR-approved career and technology education (CTE) program. Each supervisor must provide separate signed experience verification. There's no direct dollar fee for this step, but the time cost - and the cost of a CTE program if you go that route instead of on-the-job hours - is a real part of your total investment. Full eligibility details are covered in our TX-RW Requirements guide.
Study Materials
Beyond your code book, most candidates invest in a structured prep resource covering all ten exam domains. Practice testing through our TX-RW practice test platform is typically far cheaper than a failed $64 attempt, making it one of the higher-value costs in the entire process.
Key Takeaway
Budget for a compliant NEC code book and real practice-question exposure before test day - both cost less than a single failed attempt fee.
What a Retake Actually Costs You
TDLR's fiscal-year 2025 data shows a 30.15% pass rate across 1,098 Residential Wireman examination attempts - 331 passes against 767 failures, with 83 additional no-shows tracked separately. This is an exam-attempt statistic, not a first-time-candidate or 2026 figure, but it makes one thing financially clear: retakes are common, and each one costs $64.
Consider the math. A candidate who fails twice before passing has spent $192 in exam fees alone ($64 × 3), plus the $20 application fee, before ever touching a license. Compare that to investing in structured preparation upfront - reviewing the TX-RW Exam Domains guide and working through domain-specific practice questions - which costs a fraction of a single retake.
| Scenario | Exam Fees Paid | Application Fee | Total State/Test Cost |
|---|---|---|---|
| Pass on 1st attempt | $64 | $20 | $84 |
| Pass on 2nd attempt | $128 | $20 | $148 |
| Pass on 3rd attempt | $192 | $20 | $212 |

Annual Renewal and Continuing Education Costs
Passing the exam and getting licensed isn't the end of the cost timeline. The Residential Wireman license renews annually for $20, and renewal requires four TDLR-approved continuing education hours covering the NEC, Texas electrician law and rules, and NFPA 70E safety.
These CE hours typically carry their own tuition cost through approved providers, separate from the $20 TDLR renewal fee. Over a multi-year career, this recurring cost is modest compared to the initial licensing investment, but it should be part of any long-term budgeting - especially for anyone weighing the credential's overall return, which we break down in Is the TX-RW Certification Worth It?
CTE Program vs. On-the-Job Path: Cost Comparison
Because eligibility can be met either through 4,000 supervised on-the-job hours or a TDLR-approved CTE program, the path you choose significantly affects your total cost picture, even though neither path changes the $64 exam fee or $20 application fee.
- On-the-job route: No direct tuition, but requires securing employment under a licensed Master Electrician or Residential Wireman and collecting signed verification from each supervisor over the full 4,000 hours.
- CTE program route: Involves program tuition, but offers structured instruction and may compress the timeline depending on the program's format.
Neither path is inherently cheaper - it depends on your access to supervised work versus your ability to pay for structured schooling. Whichever path you choose, the exam itself remains identical: 80 scored questions plus five unscored questions, delivered in English or Spanish, covering the same ten domains.
Where to Spend and Where to Save
Given the fixed government fees, the only real cost lever candidates control is preparation spending. Here's how to allocate it wisely.
Spend Here: High-Weight Domains
The scored-item allocation is heavily concentrated in a few areas. Electrical Services, Service Equipment, and Separately Derived Systems carries 16 questions - the single largest domain - followed by Branch Circuit Calculations and Conductors at 14, and Electrical Equipment and Devices at 12. Together these three domains account for 42 of the 80 scored questions.
- Prioritize study time and practice questions on these three domains first
- Review calculation methods using copper conductors and standard methods unless a question explicitly directs otherwise
- Only apply code exceptions or optional calculation methods when the question expressly instructs you to
Save Here: Low-Weight Domains
Motors and Generators and Electrical Control Devices and Disconnecting Means each carry only 2 scored questions. Special Occupancies, Equipment, and Conditions carries 7, and Renewable Energy Technologies carries 2. These deserve familiarity, not exhaustive drilling.
- Allocate lighter review time to domains weighted at 2 questions
- Don't let low-weight domains crowd out prep time for the 16-question and 14-question domains
For the full breakdown of all ten domains and their exact question counts, see the TX-RW Exam Domains 2026 guide, and cross-check your target score against the TX-RW Passing Score guide, since the exam requires 70% to pass.
A Cost-Conscious Study Timeline
Spending money efficiently means spending study hours efficiently first. Rather than generic weekly templates, structure your remaining prep time around the exam's actual weight distribution and the 240-minute scored testing window (plus the additional 20 minutes for five unscored questions).
Anchor the Heavy Domains
- Work through Electrical Services, Service Equipment, and Separately Derived Systems (16 questions) and Branch Circuit Calculations and Conductors (14 questions)
- Practice locating relevant NEC sections quickly using your permanently tabbed code book
Mid-Weight Domains and Timed Practice
- Cover Electrical Equipment and Devices (12), Definitions, Calculations, Theory, and Plans (8), and Electrical Wiring Methods and Electrical Materials (10)
- Run timed practice sets on the practice test platform to build pacing for 80 scored questions in 240 minutes
Light Domains and Book Compliance Check
- Briefly review Electrical Feeders, Special Occupancies, and the low-weight 2-question domains
- Confirm your NEC book has no prohibited tabs, sheets, or bindings before test day

Frequently Asked Questions
The exam fee is $64 per attempt, paid to PSI, and the initial license application fee is $20, paid to TDLR. Passing on your first attempt brings your total state and testing cost to $84, not counting study materials or a code book.
Yes. The $64 fee applies per attempt. Since FY2025 data shows 767 failures out of 1,098 attempts, budgeting for at least one possible retake is a realistic financial precaution.
No. The $20 initial application fee is tied to the license application process itself, separate from exam scheduling. It's the $64 PSI exam fee that repeats with each attempt, not the TDLR application fee.
Renewal costs $20 annually through TDLR, plus completion of four TDLR-approved continuing education hours covering the NEC, Texas electrician law and rules, and NFPA 70E safety.
No. Loose-leaf, spiral-bound, or ring-bound books, the NEC Handbook, and homemade or third-party tabs are all prohibited. Only a softbound NEC with publisher-made permanent tabs is allowed, and noncompliance can cost you your exam fee if you're turned away at check-in.
