TExES 237 Study Guide 2026: How to Pass on Your First Attempt

What the TExES 237 Actually Tests

The TExES Physical Science 6-12 (237) is the certification exam the Texas Education Agency and the State Board for Educator Certification use to confirm that a candidate is ready to teach physical science - physics and chemistry content, primarily - to students in grades 6 through 12. It is administered as a computer-administered test (CAT) through Pearson VUE testing centers, using the current online 237 framework published by Evaluation Systems, Pearson.

If you're just getting oriented to this credential, it helps to first understand what the TExES 237 is and how the four content domains fit together before diving into a study plan. This guide assumes you already know you want to sit for the exam and are ready to build a real preparation strategy for 2026.

Exam Format, Fees, and Scheduling Mechanics

Knowing the mechanics of test day removes a layer of anxiety that has nothing to do with your science knowledge. The TExES 237 consists of 100 selected-response questions. Your appointment window is 5 hours total, but only 4 hours 45 minutes of that is actual testing time - the remaining 15 minutes covers the tutorial and the compliance agreement you must accept before starting.

• Format: Computer-administered test (CAT), 100 selected-response items
• Standard fee: $116
• Testing time: 4 hours 45 minutes within a 5-hour appointment
• Provided tools: On-screen scientific calculator, Periodic Table, and a Definitions and Physical Constants reference
• Passing score: 240 on the scaled-score system

Because the calculator and constants reference are built into the testing software, you don't need to burn study time memorizing values like the gas constant or Avogadro's number - you need to know when and how to apply them.

Domain-by-Domain Breakdown

The single biggest strategic decision you'll make in preparing for the TExES 237 is how you allocate study time across its four domains. They are not weighted evenly, and treating them as if they were is the most common planning mistake candidates make.

For a much deeper dive into subtopics, sample item styles, and how the domains interrelate on test day, read the full TExES 237 exam domains guide. Since Chemistry (41%) and Physics (36%) together account for the large majority of the exam, most of your study calendar should live there - Domains 1 and 4 combined are still less than a quarter of the test.

Understanding the Passing Score

The TExES 237 uses a scaled-score system, and the passing threshold is 240. Scaled scores are not the same as raw percentages - the scale accounts for the specific mix of items you receive, so you can't simply assume you need to answer a fixed percentage of the 100 selected-response questions correctly. What matters is your performance relative to the scaled range around 240.

Because Chemistry and Physics dominate the item pool, your path to 240 runs primarily through solid, consistent performance in those two domains rather than trying to ace the smaller sections while guessing through the larger ones. For a detailed explanation of how scaled scoring works and what a near-miss score typically indicates, see TExES 237 passing score.

A Domain-Weighted Study Timeline

A generic weekly study template won't serve you well here because the domain weights are so uneven. Instead, build your calendar around the actual percentages: heavy blocks for Chemistry and Physics, lighter but focused blocks for Scientific Inquiry and for Science Learning, Instruction and Assessment.

This sequencing front-loads the two domains that make up 77% of the exam, then closes with the smaller domains and a full-length timed simulation. If your available prep time is shorter or longer than six weeks, keep the ratio intact rather than the exact week count - Chemistry and Physics should always consume roughly three-quarters of your total hours.

Common Mistakes That Sink First Attempts

Most candidates who don't pass on the first try aren't failing because they lack science knowledge in general - they're failing because their preparation didn't match the exam's actual structure. A few recurring patterns:

• Treating all four domains equally. Spending the same number of hours on Science Learning, Instruction and Assessment (9%) as on Chemistry (41%) is a math error before it's a content error.
• Ignoring the provided references. Since the on-screen calculator, Periodic Table, and Definitions and Physical Constants reference are built in, candidates who don't practice with equivalent tools waste time relearning navigation on test day instead of applying concepts.
• Underestimating the pacing. With 100 selected-response items across roughly 4 hours 45 minutes, you have an average of under three minutes per question - but Chemistry and Physics items often involve multi-step calculations that take longer, so simpler inquiry and pedagogy questions need to move faster.
• Skipping domain-specific practice questions. Generic physical science trivia isn't the same as practicing the selected-response style used on this specific exam.

You can sharpen your instincts on question style and pacing using realistic practice questions on our TExES 237 practice test platform, which mirrors the selected-response format you'll see on exam day.

Retake Policy and What Happens If You Don't Pass

If your scaled score comes in under 240, you are not locked out for long, but there are real constraints to plan around. Candidates must wait 30 days before retaking the TExES 237, and the standard limit is five total attempts, after which a waiver process applies. That means your retake strategy needs to be deliberate rather than a quick re-cram.

Before you even schedule your first attempt, it's worth confirming you meet the underlying eligibility requirements - bachelor's degree, an approved educator preparation program, program approval to test, and background/fingerprint checks are all part of the standard classroom-teacher pathway. Full details are in TExES 237 requirements.

What Happens After You Pass

Passing the TExES 237 is a milestone toward - not the finish line of - Texas classroom-teacher certification. The certification pathway also requires an approved educator preparation program, a completed application, and fingerprint/background checks alongside your passing exam score. Once issued, the standard classroom-teacher certificate must be renewed every five years, and that renewal requires 150 CPE hours; the exam score itself does not expire on a five-year clock the way the certificate renewal does.
