Exam Format at a Glance
Before you memorize a single content fact, lock in the mechanics of the test itself. TExES Physical Science 6-12 (237) is a computer-administered test (CAT) delivered at Pearson VUE test centers on behalf of the Texas Education Agency and the State Board for Educator Certification. You'll answer 100 selected-response questions, and your appointment window is 5 hours total, with 4 hours 45 minutes of actual testing time. The remaining 15 minutes cover the tutorial and compliance agreement, so budget your energy accordingly - this is a long sitting, not a quick quiz.
If you want the mechanics broken down question-by-question with sample item styles, the TExES 237 Study Guide 2026 walks through pacing strategies for a 100-item, nearly five-hour test.
Registration & Fee Snapshot
The standard exam fee is $116, paid when you register through the Pearson VUE system used for Texas educator certification testing. Before you're even eligible to schedule, most candidates need program approval to test from an approved educator preparation program, since initial classroom-teacher certification in Texas runs through a defined pathway of degree, EPP enrollment, exam completion, application, and fingerprint/background checks. Candidates who already hold a certificate and are adding this one follow a separate additional-certification route rather than the full initial pathway.
For the complete cost picture - including how the exam fee fits into the larger certification budget - see the TExES 237 Certification Cost 2026 breakdown. If you're still confirming whether you meet the prerequisites to register at all, the TExES 237 Requirements 2026 guide covers eligibility in detail.
The Four Domains in One Pass
Everything on this exam sorts into four domains, and their weights should directly shape how you allocate study hours. Memorize this table before you memorize anything else.
| Domain | Weight | Study Priority |
|---|---|---|
| Domain 3: Chemistry | 41% | Highest - build your schedule around this first |
| Domain 2: Physics | 36% | Second priority, nearly as heavy as Chemistry |
| Domain 1: Scientific Inquiry and Processes | 14% | Moderate - foundational skills, fewer items |
| Domain 4: Science Learning, Instruction and Assessment | 9% | Smallest - pedagogy-focused content |
Notice that Chemistry and Physics together account for 77% of the exam. That means a study plan that treats all four domains equally is a losing strategy. For a full content breakdown of every competency inside each domain, use the TExES 237 Exam Domains 2026 guide alongside this cheat sheet.
Domain 1: Scientific Inquiry and Processes (14%)
Covers the scientific method, laboratory safety, data analysis, measurement, and experimental design as applied across both physics and chemistry contexts.
- Know significant figures, unit conversions, and error analysis cold
- Understand controlled variables and experimental design flaws
- Review lab safety protocols specific to secondary science classrooms
Domain 4: Science Learning, Instruction and Assessment (9%)
Focuses on how to teach physical science effectively to grades 6-12, including assessment design and differentiation.
- Understand formative vs. summative assessment purposes
- Know common misconceptions students hold in physics and chemistry
- Be familiar with inquiry-based and safety-conscious lesson planning
Chemistry: The Domain That Decides Your Score
Because Chemistry is worth 41% - more than any other single domain - it deserves the first and largest block of your study time. Candidates who treat Chemistry as "just one of four domains" consistently underestimate how much of the exam it touches.
Domain 3: Chemistry (41%)
Spans atomic structure, periodicity, bonding, stoichiometry, thermochemistry, reaction types, solutions, acids and bases, and nuclear chemistry.
- Master the Periodic Table's organizing trends: atomic radius, electronegativity, ionization energy
- Practice balancing equations and stoichiometric calculations until they're automatic
- Know the difference between physical and chemical changes, and common reaction categories
- Review acid-base theory (Arrhenius, Brønsted-Lowry) and pH calculations
Physics Fast Facts
Physics at 36% is nearly as heavy as Chemistry, and the two domains together make up the bulk of your score. Don't let Chemistry's slightly larger weight cause you to shortchange Physics prep.
Domain 2: Physics (36%)
Covers mechanics, energy, waves, electricity and magnetism, and thermodynamics as taught at the secondary level.
- Review Newton's laws, kinematics equations, and force diagrams
- Know work-energy theorem and conservation of energy problems
- Understand wave properties: frequency, wavelength, amplitude, and the electromagnetic spectrum
- Practice circuit analysis basics - series vs. parallel, Ohm's law
Since the on-screen scientific calculator and the Definitions and Physical Constants reference are both available during the test, focus your memorization effort on concepts and formula application rather than raw constant values. Knowing when to use a formula matters more than recalling it from memory.
Scientific Inquiry & Instruction Quick Hits
Domains 1 and 4 together make up only 23% of the exam, but they're often where candidates lose easy points simply because they didn't review them at all.
- Scientific method sequencing: hypothesis, variables, controls, data collection, analysis, conclusion - know the correct order and terminology.
- Lab safety: chemical storage, protective equipment, and emergency procedures appropriate for a 6-12 science classroom.
- Assessment types: distinguish diagnostic, formative, and summative assessment purposes and when each is used.
- Common misconceptions: be ready to identify typical student misunderstandings in force, energy, and chemical reaction concepts.
If you're unsure how much weight to give these smaller domains relative to your overall difficulty, the How Hard Is the TExES 237 Exam? guide puts them in context against Chemistry and Physics.
On-Screen Tools You Can Actually Use
Part of passing efficiently is knowing exactly what support is built into the testing software so you don't waste memory space duplicating it.
A common mistake is over-preparing to memorize constants or symbols that are already provided, while under-preparing on how to interpret data tables, graphs, and diagrams - which are not handed to you and require independent analysis skill.
Passing Score & Retake Rules
The passing score is 240 on the scaled-score system used for this exam. If you don't reach it, you must wait 30 days before retaking, and the standard limit is five total attempts, with a waiver process available in specific circumstances.
For the full explanation of how the scaled score is calculated and what a near-miss score typically means, see TExES 237 Passing Score 2026. If you want to understand how many candidates clear that bar on a given administration, review the historical data in the TExES 237 Pass Rate 2026 article - just remember that any published administration-level rate reflects a specific testing window, not a guaranteed outcome for your attempt.
Key Takeaway
Treat 240 as a hard floor, not a target. Build your review plan to comfortably clear it, especially in Chemistry and Physics, since those two domains carry enough weight to make or break a marginal score.
Final Review Timeline
If you have one week left before test day, allocate it according to domain weight rather than personal comfort. This is not a full study plan - it's a compressed final pass built specifically around the 237 blueprint.

After You Pass
Passing the exam is one step in a larger certification process. Initial classroom-teacher certification also requires an approved educator preparation program, a completed application, and fingerprint/background checks. Once issued, the standard classroom-teacher certificate renews every five years and requires 150 CPE hours to maintain - the exam score itself doesn't expire on that same five-year clock, but your certificate does require ongoing renewal activity.

If you're weighing timing around specific testing windows, the TExES 237 Exam Dates 2026 guide covers scheduling considerations.
Whichever stage you're at, running full-length timed sets on the TExES 237 practice test platform before your final week is the single best way to confirm this cheat sheet's facts have actually stuck.
