- The TExES 238 exam fee is a flat $116 with no member or non-member pricing tiers.
- Withdrawing after registering costs $25, refunding only the remainder of the $116 fee.
- Candidates get five attempts total, each separated by a mandatory 30-day wait.
- Registration stays valid for 170 days, so scheduling delays can burn eligibility without a refund.
The $116 Exam Fee: What It Actually Covers
The TExES Life Science 7-12 (238) exam carries a flat registration fee of $116. Unlike some certification programs that charge different amounts to members versus non-members, TExES 238 has a single price point for every candidate, regardless of where they trained or which educator preparation program (EPP) sponsors them. That $116 pays for one seat on a computer-administered test (CAT) delivered through Pearson VUE testing centers across Texas and, by appointment, at locations nationwide.
Your appointment runs a total of five hours: fifteen minutes for the CAT tutorial and compliance agreement, followed by four hours and forty-five minutes of actual testing time. That block covers all 100 selected-response questions on the exam, including a handful of unscored field-test items that Pearson embeds to trial future questions. You won't know which items are scored and which are experimental, so every question deserves your full attention even though only the scored ones count toward your final result on the 100-300 scale, where 240 is passing.
Retake Costs and the Five-Attempt Ceiling
If you don't pass on your first try, you'll pay the $116 fee again for every subsequent attempt - there's no discounted retake rate. That matters because the statewide numbers show a meaningful share of candidates need more than one sitting. Reviewing exactly why the exam trips people up, and how the scoring scale works, is worth doing before you register a second time; our TExES 238 Pass Rate 2026: What the Data Shows breakdown and our TExES 238 Passing Score 2026: Exactly What You Need to Pass guide both dig into what separates a 235 from a 245.
Texas caps most candidates at five total attempts, with a mandatory 30-day waiting period between each one. If you exhaust those five attempts without passing, you need a formal waiver from TEA before you're allowed to test again. That waiver process adds time and administrative friction on top of whatever additional exam fees you'd owe, so treat each of your five attempts as genuinely limited - not something to burn casually on an under-prepared sitting "just to see."
Key Takeaway
Budget for one paid attempt, not five. Spend your preparation time closing content gaps in the three 20%-weighted domains before you schedule, rather than planning to "learn from" a failed first attempt.
Registration Windows, Withdrawals, and Refund Math
Once you register, your eligibility window is 170 days. That's generous compared to a lot of last-minute exam scheduling, but it also means candidates sometimes register too early relative to their actual readiness, then either test unprepared to avoid "wasting" the window or let it lapse and pay again.
If you decide to withdraw before testing, the refund isn't the full $116. TEA and Pearson deduct a $25 processing charge, so you get back $91. That $25 is effectively the cost of changing your mind, and it's a good reason to register only after you've mapped out a realistic study runway rather than registering the day you decide "I should probably get certified."
| Cost Scenario | Amount |
|---|---|
| Standard exam fee (per attempt) | $116 |
| Withdrawal before testing | -$25 (refund of $91) |
| Retake after a failed attempt | $116 again (30-day wait required) |
| Sixth+ attempt | $116 plus TEA waiver approval |
Scores post at 10:00 p.m. Central on the published score report date for your test window, not immediately after you finish. Plan any certificate-application deadlines or hiring timelines around that posted date rather than your test day.
Beyond the Exam Fee: The Full Certification Path
The $116 fee only covers the content exam. TExES 238 alone doesn't get you a Texas classroom certificate - if this is your first Texas certification, you also need to pass the PPR EC-12 (160) pedagogy exam, which carries its own separate registration fee and testing appointment. Anyone budgeting for "the cost of getting certified" should count both exams, not just the Life Science 7-12 content test.
Before you can even register for TExES 238, you generally need to be approved to test either through an educator preparation program (EPP) or directly through TEA. If you're going the EPP route, your program may bundle advising, coursework, or practice resources into tuition or program fees that sit outside the $116 exam charge entirely - those costs vary by institution and aren't part of the TEA/Pearson pricing structure covered here. For a full walkthrough of who's eligible to register and how EPP versus direct TEA approval works, see TExES 238 Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Why the Pass Rate Makes This Exam Expensive to Fail
TEA's statewide data for the 2024-2025 program year showed a 47% first-attempt pass rate and a 56% best-attempt pass rate on TExES 238 (N=554) - the lowest among the major secondary science content exams. That's a meaningful signal for anyone budgeting for this exam: a large share of test-takers pay the $116 fee more than once before they clear the 240 cutoff.
The financial takeaway is straightforward - every dollar spent on genuine content mastery before your first appointment is cheaper than a second $116 fee plus another 30-day wait plus a delayed hiring timeline.

Where First Attempts Typically Fall Short
Because three domains - Cell Structure and Processes, Heredity and Evolution of Life, and Diversity of Life - each carry 20% weight, roughly 60 of the 100 questions come from those three areas alone. Under-preparing any one of them is enough to push a borderline candidate below 240.
- Cell Structure and Processes: biomolecules, prokaryotic/eukaryotic structure, transport, photosynthesis and respiration, cell cycle
- Heredity and Evolution of Life: DNA/RNA structure, Mendelian and molecular genetics, mutation, natural selection, speciation
- Diversity of Life: taxonomy, plant and animal systems, homeostasis, biology of behavior
Renewal Costs Over the Five-Year Certificate Cycle
Passing TExES 238 isn't a one-time expense that ends at certification. Texas standard certificates are valid for five years and renew through the ECOS system, with classroom teachers required to complete 150 CPE clock hours during that cycle. Whether those hours come free through your district, through a paid third-party provider, or through graduate coursework varies by educator and district - but it's a recurring cost worth planning for as part of the certificate's real lifetime cost, not just the initial $116 exam fee.
Because the certificate itself isn't permanent, some candidates weigh the total investment - exam fees, PPR EC-12 (160), ongoing CPE - against the career payoff. If you're still deciding whether the full path makes sense for your goals, Is the TExES 238 Certification Worth It? Complete ROI Analysis 2026 and TExES 238 Salary Guide 2026: Complete Earnings Analysis both look at that bigger picture.
Where Your Study Dollars Should Actually Go
Since the exam fee is fixed regardless of how you prepare, the real "cost optimization" for TExES 238 is spending your prep time - and any money spent on materials or coaching - on the domains that carry the most points. The 2019 Life Science 7-12 framework organizes the exam into 20 competencies across six domains, and the weighting is uneven enough that a scattershot review approach wastes both time and money.
| Domain | Weight | Approx. Questions |
|---|---|---|
| Scientific Inquiry and Processes | 15% | ~15 |
| Cell Structure and Processes | 20% | ~20 |
| Heredity and Evolution of Life | 20% | ~20 |
| Diversity of Life | 20% | ~20 |
| Interdependence of Life and Environmental Systems | 15% | ~15 |
| Science Learning, Instruction and Assessment | 10% | ~10 |
Notice that the three 20% domains combine for roughly 60 of the 100 questions. If you're deciding where to spend limited study hours - or where a paid question bank subscription is worth the money - those three areas deliver the most return per hour invested. For the full competency-level breakdown of every domain, see TExES 238 Exam Domains 2026: Complete Guide to All 6 Content Areas.
Budgeting Study Time So You Only Pay Once
A structured, multi-week review schedule is the single cheapest way to avoid a second $116 charge. Rather than a generic study calendar, weight your weeks the same way the exam weights its domains - more time on the 20% content areas, proportionally less on the 10-15% ones.
Cell Structure and Processes
- Biomolecules, cell transport, and homeostasis mechanisms
- Photosynthesis and respiration pathways in detail
- Cell cycle, differentiation, and mitosis/meiosis distinctions
Heredity and Evolution of Life
- DNA/RNA structure and molecular genetics mechanisms
- Mendelian genetics problem sets and mutation types
- Natural selection, speciation, and fossil evidence interpretation
Diversity of Life
- Taxonomy and classification systems
- Plant and animal system comparisons
- Homeostasis and biology of behavior
Remaining Domains and Full Practice
- Scientific Inquiry and Processes, Interdependence of Life and Environmental Systems
- Science Learning, Instruction and Assessment
- Full-length timed practice under the actual 4-hour-45-minute limit
Because no calculator or reference sheet is provided during the exam, build recall practice into every week rather than relying on look-up tools during your review. For a step-by-step version of this approach, including how to structure practice testing, see TExES 238 Study Guide 2026: How to Pass on Your First Attempt. You can also run realistic timed sets on our TExES 238 practice test platform to gauge whether you're ready before you spend the $116 on a real appointment.
Frequently Asked Questions
No. Every attempt costs the same $116, with no discounted retake pricing. Each retake also requires waiting at least 30 days after your previous attempt.
Your registration is valid for 170 days. If you don't schedule and complete your appointment within that window, you'll need to register again and pay the $116 fee a second time.
Yes, but not the full amount. Withdrawing before testing refunds the $116 fee minus a $25 processing charge, so you receive $91 back.
No. TExES 238 and PPR EC-12 (160) are separate exams with separate fees. If this is your first Texas certification, you'll need to budget for and pass both.
You get five attempts total, each 30 days apart. Beyond five attempts, you need a waiver from TEA to test again, in addition to paying the $116 fee for that attempt.
