TExES Chemistry 7-12 Cheat Sheet 2026: One-Page Review of Must-Know Facts

Exam Snapshot: The Numbers You Must Memorize

Before you touch a single content review, lock in the logistics. The TExES Chemistry 7-12 (240) exam is governed by the Texas Education Agency through the State Board for Educator Certification and administered by Pearson under the Texas Educator Certification Examination Program. It's a computer-administered test delivered at Pearson VUE sites across Texas and nationwide, so the interface and testing-center procedures are consistent no matter where you sit.

Here's the compressed version of everything you need to know at a glance:

• Format: 100 selected-response questions
• Appointment length: 5 hours total - 15 minutes for the CAT tutorial and compliance agreement, plus 4 hours 45 minutes of actual testing time
• Fee: $116, with no separate member versus non-member pricing (additional service fees may still apply)
• Scoring scale: 100-300, with 240 as the minimum passing score
• Tools provided: on-screen periodic table, physical constants page, and an on-screen scientific calculator

The Four Domains at a Glance

The exam framework, carrying a 2022 TEA copyright, organizes 17 competencies aligned to the Physical Science 7-12 educator standards into four domains. Memorize the weighting below before you build any study plan - it should drive how many hours you spend on each area.

Notice that Domain II alone carries almost as much weight as Domains I and III combined. That single fact should reshape your entire prep schedule. For a competency-by-competency walkthrough of all four domains, our TExES Chemistry 7-12 exam domains guide goes deeper than this cheat sheet can.

Domain II Deep Dive: Matter and Energy

Because Domain II is worth 41% of the exam - by far the largest single domain - it deserves its own section even in a condensed review. This is the domain that should anchor your entire content hierarchy, not just one week of studying.

If you're unsure how difficult this content actually feels on test day compared to college-level chemistry coursework, our article on how hard the TExES Chemistry 7-12 exam really is unpacks that question directly.

Domains I, III, and IV in Brief

These three domains together make up 59% of the exam - still substantial, but each one individually is smaller than Domain II, so your review time should be proportionally lighter here.

For a full narrative walkthrough that connects these domains to specific classroom scenarios and item styles, see the TExES Chemistry 7-12 study guide for passing on your first attempt.

Registration and Testing Day Mechanics

Eligibility and logistics trip up more candidates than the chemistry content does. Here's what to confirm before you schedule:

• You need a TEA ID before you can register for any TExES exam.
• Most candidates test after being admitted to an approved Texas educator preparation program and receiving authorization to test; alternate paths exist through certification by examination or an out-of-state credential review.
• The $116 fee applies uniformly - there's no discounted tier for any candidate group, though service fees can add to the total.
• Testing happens exclusively at Pearson VUE computer-administered sites, in Texas and at approved locations nationwide.

If you're still confirming whether you meet the eligibility criteria, our TExES Chemistry 7-12 requirements guide walks through the qualification paths in detail, and the exam dates and scheduling guide covers how to pick a testing window that fits your prep timeline.

Scoring, Passing Score, and Retake Rules

Scores are reported on a 100-300 scale, and 240 is the line you need to clear. The number "240" isn't arbitrary trivia - it's baked into the exam code itself (240), which is worth remembering as a mnemonic for the passing threshold.

• Scores typically post about seven days after your test date, at 10:00 p.m. Central on published score report dates.
• Only scored items count toward your final scaled score - unscored field-test questions on some forms don't factor in, and you can't identify which is which during the test.
• If you don't pass, you must wait 30 days before retaking.
• You're limited to five attempts total on this certification exam.

For a granular look at how the raw number of correct answers likely translates into that 100-300 scale, read our dedicated breakdown of the TExES Chemistry 7-12 passing score.

A One-Week Final Review Timeline

If you've already done the bulk of your studying and just need a structured final push, weight your last week to match the domain percentages rather than splitting time evenly across four domains.

This weighting isn't generic advice for its own sake - it directly mirrors the 41/24/23/12 split across the four domains, so the days you spend match the points available on test day.
