What Is TExES 236?

What Is TExES 236, Exactly?

TExES 236 is the shorthand educators use for the Science 7-12 (236) certification exam, one of the content-area tests within the Texas Examinations of Educator Standards (TExES) system. The Texas Education Agency (TEA) sets the standards and passing requirements, while Pearson builds and administers the computer-based test at approved testing centers across the state.

Passing TExES 236 is the credentialing step that allows a candidate to teach science to students in grades 7 through 12 in Texas public schools - everything from middle school life science classes to high school physics and chemistry courses. It is not a general science literacy test; it is a targeted, standards-aligned exam built around the specific content a secondary science teacher is expected to know before stepping into a classroom.

Who Needs This Certification

TExES 236 is intended for candidates pursuing Texas certification to teach secondary science - typically people enrolled in an educator preparation program (EPP), university-based teacher certification track, or an alternative certification program. Most candidates need test approval through an eligible certification route before they can register; those coming through the Post-Admission Content Test (PACT) pathway follow a separate pre-admission process rather than the standard approval flow.

School districts hiring for secondary science positions - physics, chemistry, biology, integrated science, environmental science - rely on this certification as proof that a candidate has demonstrated content mastery across the full science spectrum, not just one subject.

Exam Format and Registration Details

Understanding the mechanics of test day matters just as much as knowing the content. TExES 236 is delivered entirely on computer through Pearson, and the format is consistent across every administration:

• 140 selected-response questions - some test forms may embed unscored field-test items within that total, so every question should be treated as if it counts.
• 4 hours 45 minutes of testing time, inside a 5-hour total appointment that also includes a 15-minute tutorial and a compliance agreement you must acknowledge before starting.
• $116 exam fee, paid during registration through the TEA/Pearson testing portal.
• On-screen tools provided: a scientific calculator, a periodic table, and a reference page with definitions and physical constants - no need to memorize constants you'll have on screen.

The 10 Domains Tested

TExES 236 is organized into 10 domains, each weighted differently in terms of how many questions it contributes. Two domains - Physics and Chemistry - dominate the exam blueprint at 20% each, meaning nearly half of your score depends on mastering the physical sciences.

For a deeper dive into each domain with sample question styles and study priorities, read the TExES 236 Exam Domains 2026: Complete Guide to All 10 Content Areas.

Scoring and What It Takes to Pass

TExES 236 uses a scaled score system, and candidates must reach 240 to pass. Scaled scores translate your raw number of correct answers into a standardized scale, which means the exact number of questions you need to answer correctly can shift slightly between test forms due to equating.

Because the test blends 140 selected-response questions across 10 domains of very different weights, a strong strategy is to think in terms of domain-level mastery rather than trying to memorize isolated facts. Missing a few questions in a 5%-weighted domain like Science Learning, Instruction and Assessment matters far less than missing several in Physics or Chemistry, which together make up 40% of the exam.

How Difficult Is It, Really

According to TEA's 2024-2025 statewide best-attempt report, 790 candidates attempted TExES 236, and 63% passed. That figure reflects the reality that this exam spans an unusually wide range of scientific disciplines - physics and chemistry content that many candidates haven't formally studied since undergraduate coursework, alongside biology, earth science, and astronomy topics that require their own dedicated review.

Certification Requirements and Renewal

Passing TExES 236 is one piece of a larger certification process. Most candidates need approval to test through an educator preparation program or an eligible alternative certification route before they can register; PACT candidates go through a separate pre-admission process instead. Once you're approved and have passed the exam, the credential feeds into your standard Texas classroom teacher certificate.

Texas standard classroom-teacher certificates are valid for 5 years and require 150 continuing professional education (CPE) hours to renew. That renewal cycle is worth planning for early, since CPE requirements apply on top of whatever ongoing professional development your district mandates.

Building a Domain-Based Study Plan

Rather than studying science topics in a vacuum, the most efficient approach ties your review schedule directly to the domain weights above. Since Physics and Chemistry alone account for 40% of the test, they deserve the largest blocks of dedicated study time, followed by Scientific Inquiry and Processes and Earth's History and Earth Systems.

What the Exam Actually Costs

The TExES 236 registration fee is $116, paid directly through the Pearson testing portal once your certification program has approved you to test. That fee covers the single 4-hour-45-minute testing appointment, including the built-in tutorial and access to on-screen references like the periodic table and physical-constants page. It does not include retake fees if you need a second attempt, or any prep materials you choose to purchase separately.

Because the total cost of certification includes more than just the exam fee - background checks, application fees, and potential retakes - it helps to look at the full financial picture before you register.
