TExES 236 Certification

What TExES 236 Certification Actually Is

TExES Science 7-12 (236) is the content certification exam that verifies a candidate's readiness to teach science to secondary students in Texas public schools. It is governed by the Texas Education Agency (TEA) and administered as a computer-based test through Pearson. Passing this exam is one of the core requirements for earning a standard classroom teaching certificate in the Science 7-12 field, alongside completion of an approved educator preparation program.

Unlike a general teaching aptitude test, TExES 236 is deeply content-specific. It assumes you already understand pedagogy at a foundational level and instead probes whether you can reason through physics problems, balance chemical equations, interpret ecological data, and explain earth-science processes at a level appropriate for teaching grades 7 through 12. If you're still mapping out what this credential covers before diving into study materials, the TExES 236 Exam Domains Guide breaks down every content area in depth.

Who Needs This Certification

This exam is designed for individuals seeking to become certified secondary science teachers in Texas - whether they're finishing a traditional university-based teacher preparation program, completing an alternative certification program, or working through a post-baccalaureate route. Districts hiring for middle school and high school science positions - biology, chemistry, physics, earth science, and integrated science courses - will require this certification (or evidence you are actively pursuing it) before offering a standard teaching contract.

Most candidates fall into one of these categories:

• University education majors completing a science-focused teacher preparation track
• Career changers with a science degree entering education through an alternative certification program
• Out-of-state or out-of-country teachers seeking Texas reciprocity in a science teaching field
• Current teachers adding a science certification to their existing credential

If you're trying to confirm whether this is the right exam for your career path, the article What Is TExES 236? and its companion piece TExES 236 Meaning walk through the certification's purpose and how it fits into Texas educator licensure.

Exam Structure and Format

TExES 236 consists of 140 selected-response (multiple-choice) questions. Some administered forms may embed unscored field-test items within that total, which is standard practice for maintaining exam validity - you won't know which items are field-tested, so treat every question as if it counts.

Test takers are given 4 hours and 45 minutes of actual testing time, inside a 5-hour total appointment window that includes a 15-minute tutorial and compliance agreement at the start. That means pacing matters: with 140 questions across nearly five hours, you have roughly two minutes per question on average, though science questions vary widely in complexity - some are quick recall items, others require multi-step calculations or data interpretation.

To support content-heavy questions, the test provides several on-screen tools:

• A scientific calculator
• A periodic table of elements
• A reference page of definitions and physical constants

These resources reduce the memorization burden for constants and formulas, but they don't replace conceptual understanding - you still need to know when and how to apply them correctly during Physics and Chemistry item sets.

The 10 Domains You Must Master

TExES 236 is organized into ten domains, each with a specific weight reflecting how much of the exam it represents. Understanding these weights is the single most important step in building an efficient study plan, since not all domains deserve equal study time.

Since Physics and Chemistry together account for 40% of the exam, most candidates should allocate close to half their total study time to these two domains alone. For a deeper domain-by-domain breakdown with example concepts and study strategies, read the full TExES 236 Exam Domains Guide.

Registration, Fees, and Scheduling

Before registering, most candidates need testing approval through an approved educator preparation program or certification route. PACT candidates go through a separate pre-admission testing process, so confirm which pathway applies to you before attempting to schedule.

Once approved, the exam is booked through Pearson's testing system at a fee of $116. The test is delivered at computer-based testing centers, and appointments run within a 5-hour window that includes the tutorial, the exam itself, and the compliance agreement.

Because seats at testing centers can fill up, especially near the end of a semester when many candidates are finishing their preparation programs, it's smart to lock in a date as soon as your approval comes through rather than waiting until you feel "fully ready."

Scoring and Passing Requirements

TExES 236 uses a scaled scoring system, and candidates need a scaled score of 240 to pass. Scaled scores translate raw performance across the 140 questions into a standardized scale, which allows TEA to maintain consistent passing standards across different test forms and administration dates.

According to TEA's 2024-2025 statewide best-attempt report, 790 candidates attempted this exam, with a 63% pass rate. That figure gives you a realistic sense of the exam's difficulty - a majority of candidates pass, but a meaningful share do not clear the bar on their first attempt, which underscores the value of deliberate, domain-weighted preparation rather than casual review.

If you want to understand exactly how raw performance converts to that 240 threshold, or how many questions you can afford to miss, the article TExES 236 Passing Score covers the scoring mechanics in detail. For a broader look at how the pass-rate data breaks down and what it implies about exam difficulty, see TExES 236 Pass Rate and How Hard Is the TExES 236 Exam?.

After You Pass: Certificate and Renewal

Passing TExES 236 is one piece of the certification puzzle - you'll also need to complete your educator preparation program requirements and any other state-mandated steps to receive your standard classroom teaching certificate. Once issued, a Texas standard classroom-teacher certificate is valid for 5 years. To renew it, you'll need to complete 150 continuing professional education (CPE) hours during that certification cycle.

This renewal cycle is worth planning for early in your career: spreading CPE hours across the full five years, rather than scrambling near the deadline, keeps you compliant without disrupting your teaching schedule.

A Realistic Preparation Timeline

Because Physics and Chemistry together carry 40% of the exam's weight, an effective study schedule front-loads these domains while still leaving room for the eight remaining content areas. Below is a sample structure you can adapt based on your own strengths.

This is a starting framework, not a rigid formula - if you already have a strong chemistry or biology background from prior coursework, shift more hours toward your weaker domains. For a complete week-by-week strategy with specific practice recommendations, see the TExES 236 Study Guide. And when you're ready to test your readiness under realistic timed conditions, our practice test platform mirrors the exam's question style across all ten domains.
