What Does TX PACT 738 Mean?

Breaking Down What "TX PACT 738" Actually Means

The name is a code, and every part of it tells you something specific. "TX" is Texas, the state under whose authority the exam operates. "PACT" stands for the Pre-Admission Content Test - a category of exams the Texas Education Agency (TEA) uses to check whether an aspiring teacher already knows the subject matter well enough to be admitted into an Educator Preparation Program (EPP). The "738" is the test code assigned specifically to Life Science: Grades 7-12, distinguishing it from the dozens of other PACT exams covering everything from math to history to special education.

In plain language: TX PACT 738 is the content knowledge checkpoint Texas uses to confirm a candidate has enough biology, genetics, ecology, and general science background to reasonably be admitted into a secondary-level Life Science teacher preparation track. If you're weighing whether you need to take it, the companion piece What Is TX PACT 738? walks through the bigger picture, and TX PACT 738 Meaning unpacks the terminology in more depth.

Who Administers TX PACT 738

The Texas Education Agency owns the framework and sets the policy, but the day-to-day test delivery is handled by Pearson through Pearson VUE test centers. That matters practically: you'll create your testing account, pay your fee, and schedule your appointment through Pearson's system, not directly through TEA. Testing is available year-round by appointment, at centers both in Texas and elsewhere in the country, so out-of-state candidates entering a Texas EPP aren't stuck traveling.

What the 738 Actually Tests: Five Domains

TX PACT 738 is built around five official domains broken into 15 competencies. The weights below are approximate but they tell you exactly where to concentrate your energy.

For a full competency-by-competency breakdown of everything folded into these five categories, see the TX PACT 738 Exam Domains 2026: Complete Guide to All 5 Content Areas.

Exam Format, Timing, and Question Style

TX PACT 738 consists of 125 selected-response (multiple-choice style) questions. Some appointments may include unscored field-test items mixed in - these are indistinguishable from scored questions, so there's no way to identify or skip them, which means every question deserves full attention regardless.

You get 3 hours of actual testing time. The full appointment runs 3 hours and 15 minutes, with the extra 15 minutes reserved for the on-screen tutorial and the compliance agreement you must complete before the clock starts on questions. Budget roughly 1.4 minutes per question if you want to pace evenly across all 125 items, though realistically some questions (data interpretation, multi-step genetics problems) will take longer than straightforward recall items.

A passing scaled score is 240. Scaled scores aren't raw percentages, so "240" doesn't map to a simple percent-correct figure - it reflects a weighted combination of performance across the five domains.

Registration, Fees, and Scheduling Windows

The base exam fee is $106, paid when you register through Pearson's testing system. Once you register, you have 170 days to schedule and actually sit for the exam - miss that window and you'll need to register again.

Every candidate needs a TEA ID before registering, and if you're seeking admission or transfer into an EPP you'll also need either a completed bachelor's degree or standing in your final semester of undergraduate study.

Who Actually Needs to Take This Test

Not every future Life Science teacher in Texas has to sit for PACT. It becomes a requirement specifically when a candidate's academic record doesn't already demonstrate subject-matter readiness - namely, if your overall GPA is below 2.5, or you have fewer than 15 relevant subject-area semester credit hours in life science coursework. In those cases, TX PACT 738 becomes the evidence your EPP needs to admit you into the program.

Individual EPPs can also layer on additional admission requirements beyond what TEA mandates statewide, so it's worth checking directly with your specific program. A full rundown of eligibility paths lives in TX PACT 738 Requirements 2026: Eligibility, Prerequisites & How to Qualify.

What the Passing Standard Tells You

Passing scores are set to reflect genuine content mastery, not casual familiarity. That's borne out in the outcomes: for the September 1, 2024 to August 31, 2025 program year, the statewide best-attempt pass rate among 101 test takers was 33%. That figure alone should reframe how you approach preparation - this isn't an exam candidates walk into cold and pass reliably on instinct.

Retake Rules and Attempt Limits

If your first attempt doesn't clear 240, you can retake TX PACT 738 - but not immediately. TEA policy requires at least 30 days between attempts, and your prior results need to be posted to ECOS (the Educator Certification Online System) before you're cleared to test again. If you're affiliated with an EPP, that program also has to approve your retest before you schedule.

One nuance worth knowing: PACT taken for EPP admission or for charter-school assignment purposes is exempt from the general five-attempt limit that applies to many TEA certification exams. Intensive pre-service candidates, however, remain subject to that cap, so the exemption isn't universal. If retakes are part of your plan, budgeting for the 30-day gap now avoids scheduling headaches later.

Mapping Study Weeks to Domain Weight

Generic study advice - spaced repetition, timed practice blocks, active recall - only becomes useful once it's tied to how TX PACT 738 actually weights content. Since Genetics and Evolution alone accounts for 27% of the exam, it deserves proportionally more repetition cycles than any single other domain. A reasonable allocation:

Why PACT Is Not Your Teaching Certificate

This is one of the most commonly misunderstood parts of the name. TX PACT 738 supports admission into an educator preparation program - it is a gateway exam, not a certification. Passing it demonstrates content knowledge sufficient to be accepted into a Life Science teacher prep track; it does not, by itself, authorize you to teach in a Texas classroom. Actual classroom certification comes later, through a separate TEA certification exam and completion of your EPP's requirements.
