TX PACT 738 Passing Score 2026: Exactly What You Need to Pass

What Is the TX PACT 738 Passing Score?

The Texas Education Agency (TEA) sets a passing scaled score of 240 for TX PACT: Life Science: Grades 7-12 (738). This is not a raw percentage or a simple count of correct answers out of 125 - it's a scaled score derived from your performance across the exam's five domains and 15 competencies. Understanding what 240 actually represents, and how the exam is structured to produce it, is the difference between guessing at a target and preparing with precision.

TX PACT 738 is administered by Pearson through Pearson VUE test centers on behalf of TEA. It's a computer-administered test, and candidates typically use it to satisfy TEA's pre-admission content requirement for entry into an Educator Preparation Program (EPP) - not as a standalone teaching certification. If you're still unclear on the bigger picture of what this credential does and doesn't do, the overview in What Is TX PACT 738? is a useful starting point before you dig into score mechanics.

How the Scaled Score System Actually Works

Scaled scoring exists so that scores are comparable across different exam forms, even when different candidates receive slightly different sets of field-test items. TX PACT 738 may include unscored field-test questions mixed in with the 125 scored selected-response items on your exam. You won't know which questions are field-tested and which count toward your score - so every question deserves your full attention, even ones that feel unusual or oddly worded.

Because the raw number of correct answers is converted into a scaled score, you can't calculate your pass/fail status by simply dividing correct answers by 125. What you can do is treat 240 as a threshold that reflects reasonably strong, consistent performance across all five domains - not perfection in any one area, and not a scraped-together patchwork of lucky guesses.

Exam Format and What 240 Really Requires

TX PACT 738 consists of 125 selected-response questions, delivered by computer. The testing time itself is 3 hours, and your total appointment runs 3 hours 15 minutes, with the extra 15 minutes covering the tutorial and compliance agreement before the clock starts on content questions. An on-screen scientific calculator is provided, which matters for quantitative items in genetics ratios, population ecology calculations, and basic biochemistry stoichiometry.

Hitting 240 means you need enough correct responses, spread appropriately across content areas, to clear the scaled threshold. Because the exam draws from five domains of very different sizes, a candidate who is excellent in one narrow domain but weak in a heavily weighted one is far less likely to reach 240 than a candidate with solid, even performance everywhere. For a full breakdown of exactly what's tested inside each domain, see TX PACT 738 Exam Domains 2026: Complete Guide to All 5 Content Areas.

Domain Weights and Where Points Are Won or Lost

The official framework organizes TX PACT 738 into five domains and 15 competencies. Because reaching 240 depends on performance across the whole test, the domain with the heaviest weight has an outsized influence on your final scaled score. Here's how the five domains break down:

Genetics and Evolution, at 27%, is the single largest domain - meaning roughly a quarter of your scored questions likely draw from topics like inheritance patterns, molecular genetics, natural selection, speciation, and evidence for evolution. If you're deciding where to spend extra review time when your schedule is tight, this domain should generally get first priority, followed closely by Nature of Science, Biological Unity and Diversity, and Ecology and Environment, which are tied at 20% each. Biochemistry and Cell Biology, at 13%, is the smallest domain but still requires solid grounding in cellular structures, metabolic pathways, and macromolecules - you simply can't afford to skip it entirely just because it carries less weight.

For a competency-by-competency walkthrough of what each domain actually tests - not just the percentages - the companion guide at TX PACT 738 Exam Domains 2026 pairs well with this scoring breakdown.

What the Pass Rate Data Suggests About 240

TEA's reported statewide best-attempt pass rate for the September 1, 2024 through August 31, 2025 program year was 33% among 101 test takers. That figure reflects candidates' best attempt during that period, and it's a meaningful signal: reaching 240 is not a trivial bar cleared by casual review. It rewards candidates who treat the exam's breadth seriously across all five domains rather than cramming a single content area.

It's worth being cautious about reading too much into a single year's number from a relatively small candidate pool, but the underlying message is consistent with what the domain structure suggests - success on TX PACT 738 depends on even coverage, not a few areas of deep expertise. For more context on how this pass rate compares across years and what it might mean for your own preparation timeline, see TX PACT 738 Pass Rate 2026: What the Data Shows.

If You Miss 240: Retake Rules and Timelines

If your scaled score falls short of 240, you can retake TX PACT 738, but there are firm rules to plan around:

• You must wait at least 30 days between exam attempts.
• Prior results must be posted to ECOS before you can register again.
• If you're affiliated with an EPP, you'll need EPP retest approval before scheduling another attempt.
• PACT taken for EPP admission or charter-school assignment purposes is exempt from the standard five-attempt limit, though intensive pre-service candidates remain subject to that cap.
• Once you register, you must schedule and take the exam within 170 days.

These rules mean a failed attempt at 240 isn't just an emotional setback - it's a scheduling event with real logistical constraints. If you're on a tight EPP admission timeline, factor the 30-day minimum wait directly into your application plans, and confirm your EPP's retest approval process well before you need it. The TX PACT 738 Requirements 2026 guide covers eligibility details, including the GPA and credit-hour thresholds (below a 2.5 GPA or fewer than 15 relevant subject-area semester credits) that determine whether PACT is required for your program admission in the first place.

A Domain-Ordered Study Plan Built Around the Score

Because reaching 240 depends on even performance rather than a single strength, the most efficient study sequence follows the domain weights directly. Here's a simple way to allocate a multi-week runway before your test date, adjusted for your available time:

This structure isn't a generic weekly template - it's ordered specifically by TX PACT 738's own domain weights so that your limited study hours go where the scaled score is most sensitive. For a deeper, step-by-step version of this approach with specific content checklists, see TX PACT 738 Study Guide 2026: How to Pass on Your First Attempt. And when you're ready to test your readiness under realistic conditions, full-length practice exams on our practice test platform are one of the most direct ways to see whether your current preparation would clear 240.

It's also worth budgeting for the exam itself: the $106 base fee and any retake costs add up if you don't prepare deliberately the first time.
