- The base fee for TX PACT: Life Science: Grades 7-12 (738) is $106 per attempt.
- Retakes require at least a 30-day wait, and each attempt costs the same base fee again.
- You have 170 days from registration to schedule and sit for the exam before your window closes.
- Genetics and Evolution carries the heaviest weight at 27%, so under-preparing there raises retake risk and cost.
TX PACT 738 Exam Fee Overview
TX PACT: Life Science: Grades 7-12 (738) is a Texas Education Agency (TEA) content test administered through Pearson at Pearson VUE test centers, with year-round appointment-based testing available in Texas and nationwide. The base exam fee is $106 per attempt. That fee covers a single scheduled sitting of the computer-administered test, which consists of 125 selected-response questions (some appointments may include unscored field-test items mixed in) delivered across a 3-hour testing period, inside a total appointment window of 3 hours 15 minutes that includes a 15-minute tutorial and compliance agreement.
Unlike many teacher certification exams that bundle multiple content areas, TX PACT 738 is a single-subject test built around five domains. If you're not yet sure how the domain structure works or how questions are weighted, the TX PACT 738 Exam Domains 2026: Complete Guide to All 5 Content Areas breaks down all 15 competencies in detail. Understanding the weighting matters directly for cost planning: heavier domains deserve more study hours before you spend money on an attempt.
What the $106 Fee Actually Covers
The base fee pays for one seat at a Pearson VUE test center and the scoring/reporting of that single attempt. It includes access to an on-screen scientific calculator provided during the test, so you don't need to purchase or bring a separate calculator. It does not include:
- Study guides, practice questions, or prep courses
- Any rescheduling or late-cancellation charges Pearson VUE may apply outside the standard window
- A second attempt if you don't meet the 240 passing score
Because the fee is per-attempt rather than per-topic, candidates who spread their preparation thin across all five domains and go in underprepared on the highest-weighted content often end up paying twice. This is one reason the historical statewide best-attempt pass rate sits at 33% among 101 test takers for the September 1, 2024-August 31, 2025 program year - a number worth sitting with before you assume one attempt will be enough. For a deeper look at what that pass rate implies for your own preparation timeline, see TX PACT 738 Pass Rate 2026: What the Data Shows.
Genetics and Evolution (27%)
This is the single largest domain on TX PACT 738 and the one most likely to determine whether your $106 gets you a passing scaled score of 240 or a second bill.
- Mendelian and molecular genetics, inheritance patterns, and gene expression
- Mechanisms and evidence of evolution, including natural selection and speciation
- Population genetics concepts that frequently appear across multiple competencies
Retake Costs and the 30-Day Rule
If you don't reach the 240 passing scaled score on your first attempt, you'll need to register again and pay the $106 base fee a second time - the fee structure does not offer a discounted retake rate. Two mechanical rules shape when and how you can retake:
- You must wait at least 30 days between exam attempts.
- Your prior results must post to ECOS, and if you're affiliated with an Educator Preparation Program (EPP), you'll need EPP retest approval before scheduling again.
There's an important nuance on attempt limits. Candidates taking PACT for EPP admission or for a charter-school assignment are exempt from the five-attempt limit. Intensive pre-service candidates, however, remain subject to that cap. If you're unsure which category applies to you, review TX PACT 738 Requirements 2026: Eligibility, Prerequisites & How to Qualify before you register the first time - knowing your candidate category up front avoids wasted fees later.
Key Takeaway
Treat every $106 attempt as a real cost decision. A 30-day mandatory gap between attempts means a failed first try can add a month or more to your EPP admission timeline, not just money to your budget.
Registration Mechanics and the 170-Day Clock
Once you register for TX PACT 738, you have 170 days to schedule and take the exam. This window is a cost consideration as much as a scheduling one: if you register before you're actually ready to test, you're not necessarily losing money immediately, but you are running a clock that pressures you into sitting for the exam before your preparation is solid - increasing the odds you'll need a costly retake.
Eligibility for EPP admission or transfer requires either a bachelor's degree or final-semester standing, plus a TEA ID. PACT itself is required for admission specifically when a candidate's GPA is below 2.5 or when they have fewer than 15 relevant subject-area semester credits; individual EPPs may layer on additional requirements beyond that baseline. If you want the exact dates, appointment windows, and how the 170-day rule interacts with EPP admission deadlines, the TX PACT 738 Exam Dates 2026: Testing Windows, Deadlines & Scheduling guide walks through the scheduling logic in more detail.
Who Pays for TX PACT 738 and When
TX PACT 738 supports admission into an EPP - it is not itself a teaching certificate, and teaching certification is a separate process handled afterward. That distinction matters for cost timing:
- Pre-admission candidates: Typically pay the $106 fee out of pocket before or during their EPP application, since the score gates entry to the program.
- Transfer candidates: Also cover the fee themselves when moving into life science certification from another pathway, needing a bachelor's degree or final-semester standing plus a TEA ID.
- Charter-school assignment candidates: Pay the same base fee, but are exempt from the five-attempt limit that constrains intensive pre-service candidates.
Some EPPs reimburse or subsidize the fee as part of onboarding, but that's a program-level policy decision, not part of the TEA/Pearson fee structure itself - confirm directly with your program rather than assuming reimbursement. If you're still mapping out what "PACT" means in your specific admission context, What Is TX PACT 738? and TX PACT 738 Requirements 2026: Eligibility, Prerequisites & How to Qualify are good starting points before you commit the $106.
Indirect Costs: Study Time and Materials
The exam fee is fixed, but the real cost variable is preparation time and materials. Candidates who structure their review around the actual five-domain framework - rather than generic science trivia - tend to need fewer attempts, which is where the real savings happen. A focused review plan built around the domain weights, working through practice questions on a dedicated practice test platform, and targeted content review tend to cost less overall than a vague "study everything equally" approach that risks a $106 retake.

Genetics and Evolution + Biochemistry and Cell Biology
- Start with the 27%-weighted domain first since it carries the most scoring impact
- Layer in Biochemistry and Cell Biology (13%) alongside it since molecular concepts overlap
Biological Unity and Diversity + Ecology and Environment
- Cover both 20%-weighted domains, using practice questions to check retention
- Cross-reference with the exam domains guide for competency-level detail
Nature of Science + Full Review
- Finish with Nature of Science (20%), then run full-length practice sessions
- Confirm readiness against the 240 passing scaled score before scheduling
Cost Comparison by Scenario
The table below outlines how total spending on TX PACT 738 changes depending on how many attempts a candidate needs. These figures use only the confirmed $106 base fee; they don't assume any additional charges that aren't part of the published fee structure.
| Scenario | Attempts | Base Fee Total | Minimum Timeline Impact |
|---|---|---|---|
| Pass on first attempt | 1 | $106 | None beyond standard scheduling |
| One retake needed | 2 | $212 | Adds at least 30 days (mandatory retake gap) |
| Two retakes needed | 3 | $318 | Adds at least 60 days across two gaps |
Given that the historical statewide best-attempt pass rate is 33%, treating the first attempt as your only planned expense is optimistic. Building in either a stronger initial preparation timeline or a contingency budget for a second attempt is the more realistic approach.
Budgeting Study Time Across the Five Domains
Since every attempt costs the same $106 regardless of how close you come to the 240 scaled score, the highest-leverage cost-saving move is allocating study time proportionally to domain weight rather than evenly across all five domains:
Domain Weight Snapshot
- Nature of Science - 20%
- Biochemistry and Cell Biology - 13%
- Genetics and Evolution - 27%
- Biological Unity and Diversity - 20%
- Ecology and Environment - 20%
All weights are approximate, but the pattern is clear: Genetics and Evolution alone accounts for more than a quarter of the exam, roughly double the weight of Biochemistry and Cell Biology. Spending proportionally less time on the smallest domain and more on the largest is a direct way to protect your $106 investment.
