TX PACT 740 Passing Score 2026: Exactly What You Need to Pass

What "Passing" Actually Means on the TX PACT 740

Every candidate preparing for TX PACT: Chemistry: Grades 7-12 (740) eventually asks the same question: how many questions do I actually need to get right? It's a fair question, but the honest answer is that the Texas Education Agency (TEA) and Pearson Evaluation Systems don't report a passing threshold in raw questions correct. Instead, TX PACT 740 uses a scaled score, and the number you need to clear is 240.

That single number - 240 - is the entire target. It's not 240 out of 300 in some abstract sense tied to another exam; it's the specific scaled passing score for this specific chemistry content test. If you've seen different passing scores referenced elsewhere for something also abbreviated "TX PACT 740," those numbers belong to a different credential and should be disregarded for this exam.

Understanding the 240 Scaled Score

Scaled scoring exists so that Pearson and TEA can hold the passing standard constant even as individual test forms vary slightly in difficulty. Rather than counting raw correct answers and dividing by 125, the testing program converts your performance into a scaled score using a statistical model that accounts for question difficulty across the pool.

In practice, this means two candidates who each answer a slightly different mix of questions correctly - but at comparable difficulty levels - can both land at or above 240. It also means you cannot reverse-engineer "I need exactly 87 correct" with certainty, because the conversion isn't a simple linear percentage. What you can control is your mastery across all five domains, since scaled scoring rewards consistent competency rather than lucky guessing on a handful of items.

Raw Questions vs. Scaled Score: Why Math Alone Won't Tell You

A common mistake among candidates is assuming a fixed percentage - say, 70% or 75% - automatically equals passing. Because the scaled score model incorporates item difficulty and because unscored field-test questions are mixed into your 125 items without being counted, a simple percentage calculation doesn't hold up. Two candidates could each miss a similar number of questions and land on opposite sides of 240 depending on which questions those were.

This is one of many reasons candidates researching how hard the TX PACT 740 exam really is come away realizing that difficulty isn't just about content volume - it's about how the scoring model interacts with content coverage. If you want a broader look at how test-takers perform overall, the TX PACT 740 pass rate data is a useful companion resource, though it should be read alongside your own domain-by-domain readiness rather than treated as a guarantee.

How Domain Weighting Shapes Your Path to 240

Because the passing score is a single scaled number derived from performance across the whole test, the exam's domain weighting tells you exactly where to invest your preparation time. TX PACT 740 is organized into five domains subdivided into 17 competencies:

Notice that Energy and Chemical Bonding and Chemical Reactions together make up 46% of the entire exam - nearly half of your scaled score outcome traces back to these two domains. That's not a rounding error; it's a structural signal about where the test concentrates its questions.

For a full competency-level breakdown of all five domains - including the three domains not detailed above - see the complete guide to all five TX PACT 740 content domains. That resource pairs well with this one because reaching 240 is really about distributing study effort according to domain weight, not guessing at difficulty.

Unscored Field-Test Items and What They Mean for You

One detail that surprises many candidates: your 125-question exam may include unscored field-test questions mixed in alongside scored ones. These field-test items are being trialed for future exam forms, and you won't be told which questions are which. Your final scaled score is calculated using only the scored questions.

The practical implication is simple but important - treat every question on the exam with equal seriousness. You cannot skip or rush through items you suspect are field-test because you have no reliable way to identify them, and doing so risks skipping a scored question by mistake.

Building a Score-Focused Study Plan

Given that Energy and Chemical Bonding and Chemical Reactions together represent 46% of the test, your weekly plan should reflect that weight rather than splitting time evenly across five domains. A domain-proportional approach might look like this:

This isn't a generic study calendar - it's built directly from the exam's own weighting.

Test-Day Mechanics That Affect Your Score

TX PACT 740 is a computer-administered test delivered at Pearson test sites in Texas and nationwide. The $106 exam fee covers your seat, and your appointment totals 4 hours: 15 minutes for the CAT tutorial and compliance agreement, followed by 3 hours and 45 minutes of actual testing time.

Three tools are built into the testing interface, and knowing how to use them efficiently before test day matters for your pacing toward 240:

• An on-screen periodic table - you won't need to memorize atomic masses or configurations by heart, but you should be fast at reading and applying it.
• A constants and formulas page - practice pulling from a similar reference sheet during prep so you're not searching for it cold during the real exam.
• An on-screen scientific calculator - get comfortable with its layout ahead of time; fumbling with an unfamiliar calculator interface costs time you don't get back.

If you're still finalizing eligibility or scheduling logistics, review the eligibility and prerequisite requirements and the current testing windows and scheduling deadlines before locking in a study timeline around a specific appointment date.

What Happens If You Miss 240

TX PACT is specifically designed for candidates who hold a bachelor's degree and have not yet been admitted to a Texas-approved educator preparation program (EPP), giving them a way to demonstrate content mastery for EPP admission purposes. Because of this purpose, PACT exams taken for EPP admission are not subject to the standard five-attempt certification test limit that applies to other TEA certification exams.

That said, candidates testing through the intensive pre-service route are limited to five attempts, and a 30-day waiting period applies between attempts regardless of route. If you don't reach 240 on your first try, use that mandatory 30-day window productively: revisit your domain-level performance, focus disproportionately on Energy and Chemical Bonding and Chemical Reactions given their combined 46% weight, and retest with a plan rather than repeating the same preparation.

For candidates weighing whether pursuing this content test is worthwhile relative to their broader career goals, the ROI analysis on whether TX PACT 740 certification is worth it and the earnings analysis for TX PACT 740 are worth reviewing before and after your first attempt. You can also sharpen your readiness using realistic practice questions on the main TX PACT 740 practice test platform, which lets you rehearse pacing across all five domains under timed conditions.
