- "TExES 235" is the Texas Examinations of Educator Standards code for the Mathematics 7-12 certification test.
- TEA and SBEC govern the exam; Pearson develops and delivers it as a 100-question computer-administered test.
- Domain II, Patterns and Algebra, carries 33% of the exam - roughly a third of every score.
- Passing requires a scaled score of 240 out of 100-300, not a fixed percentage of questions correct.
What "TExES 235" Actually Means
The letters stand for Texas Examinations of Educator Standards, the statewide testing program Texas uses to certify classroom teachers. The number 235 is simply the exam code assigned to one specific test in that program: Mathematics 7-12. So when someone says "TExES 235," they mean the secondary mathematics certification exam - not a generic credential, and not any similarly-numbered test from another state or agency. If you're still getting oriented to the acronym itself, the companion piece What Is TExES 235? walks through the basics in more depth.
Understanding this naming convention matters because it explains the exam's scope. "Mathematics 7-12" tells you the certificate covers middle school through high school math instruction in Texas public schools. Everything about the test - its content domains, its difficulty, its calculator policy - flows from that grade-band and subject-area design, not from some abstract "235" standard.
Who Governs and Delivers the Exam
The Texas Education Agency (TEA), working with the State Board for Educator Certification (SBEC), owns the standards behind the exam. Pearson (through its Evaluation Systems group) develops the test items and administers the exam as a computer-administered test (CAT) at Pearson VUE centers across Texas and nationwide, by appointment, year round. That distinction - TEA sets policy, Pearson delivers logistics - explains why registration, scheduling, and score reporting all run through Pearson's systems even though the certificate itself is issued by the state.
Before you can even schedule a seat, you need approval to test, either through an educator preparation program (EPP) or directly through TEA. The full eligibility picture, including how the PPR EC-12 (160) pedagogy exam fits alongside this one for a first classroom certificate, is covered in TExES 235 Requirements 2026: Eligibility, Prerequisites & How to Qualify.
The Six Domains Behind the Number
The current version of the exam is built on the 2021 Mathematics 7-12 framework, which organizes content into 21 competencies spread across six domains. Each domain maps to the Mathematics 7-12 Standards I-VIII and to the Texas Essential Knowledge and Skills (TEKS) that classroom teachers must be able to teach.
Domain I: Number Concepts (14%)
Number systems, number theory, and the reasoning that underlies arithmetic and algebraic thinking at the secondary level.
- Properties of real and complex number systems
Domain II: Patterns and Algebra (33%)
The single largest domain by a wide margin - roughly a third of the entire exam. Mastery here is non-negotiable.
- Sequences, series, and mathematical induction
- Attributes of functions and relations
- Linear, quadratic, polynomial, rational, radical, absolute value, and piecewise functions
- Exponential, logarithmic, trigonometric, and circular functions
- Differential and integral calculus concepts
Domain III: Geometry and Measurement (19%)
Spatial reasoning, measurement systems, and geometric proof, tested at a level appropriate for secondary instruction.
- Coordinate and transformational geometry
Domain IV: Probability and Statistics (14%)
Data analysis, probability models, and statistical inference as they appear in a 7-12 curriculum.
- Descriptive and inferential statistics
The remaining two domains - Mathematical Processes and Perspectives, and Mathematical Learning, Instruction and Assessment - each carry 10% and shift the focus from pure content knowledge to how a teacher reasons about, communicates, and assesses mathematics in a classroom setting. For a deeper breakdown of every competency inside all six domains, see TExES 235 Exam Domains 2026: Complete Guide to All 6 Content Areas.
Format, Fee, and Registration Mechanics
The exam itself consists of 100 selected-response questions. Some of these are unscored field-test items that TEA uses to evaluate future questions, but you won't know which ones are field-tested, so every question deserves full attention. Only the scored items count toward your final result.
Your testing appointment runs 5 hours total: 15 minutes for the CAT tutorial and a compliance agreement, plus 4 hours 45 minutes of actual testing time. The exam fee is $116, with no separate member or non-member pricing tiers. Registration stays valid for 170 days, and if you withdraw before testing, you're refunded the exam fee minus a $25 processing charge. A full cost breakdown, including how this fee fits into total certification expenses, is available in TExES 235 Certification Cost 2026: Complete Pricing Breakdown.
| Exam Detail | Specification |
|---|---|
| Total questions | 100 selected-response (includes unscored field-test items) |
| Appointment length | 5 hours (15 min tutorial + 4 hrs 45 min testing) |
| Exam fee | $116 (flat, no tiers) |
| Passing score | 240 on a 100-300 scale |
| Attempts allowed | 5, with a 30-day wait between attempts |
| Registration validity | 170 days |
One quirk worth knowing: TExES 235 is one of only three TExES exams where you must bring your own graphing calculator. Approved models are limited to the TI-73, TI-83, TI-84, and the Nspire handheld fitted with a TI-84 keypad - and if you use the Nspire, that keypad cannot be removed during the test. A Definitions and Formulas page is provided on screen, but it won't compensate for showing up without an approved calculator.
What "Passing" Means on the 100-300 Scale
Scores are reported on a 100-300 scale, and you need a scaled score of 240 to pass. That scale isn't a raw percentage of correct answers - it's a converted score that accounts for the mix of scored questions on your particular form. Scores post at 10:00 p.m. Central on the published score report date, so you won't get results the moment you walk out of the testing center.
Statewide data from the 2024-2025 program year (N=1,024) showed a 61% first-attempt pass rate and a 67% best-attempt pass rate. If a candidate doesn't pass, TEA requires a 30-day wait before the next attempt, and candidates get five total attempts before needing a TEA test-limit waiver. For the mechanics of exactly how the scaled score is calculated and what it takes to clear 240, read TExES 235 Passing Score 2026: Exactly What You Need to Pass; for the fuller statistical picture, see TExES 235 Pass Rate 2026: What the Data Shows.
Key Takeaway
A 240 passing score means your goal is a consistent, broad command of all six domains - not a narrow focus on memorizing formulas for the highest-weighted domain alone.
Who Needs This Certification
TExES 235 exists for one purpose: verifying that a candidate is ready to hold a standard Texas certificate to teach mathematics in grades 7 through 12. That includes middle school pre-algebra and algebra teachers, high school geometry and algebra II teachers, and instructors of upper-level courses like precalculus, statistics, and calculus. Once earned, a standard Texas certificate is valid for five years and renews through ECOS with 150 CPE clock hours for classroom teachers.
Because certification opens the door to public school hiring across Texas, many candidates want to know what comes after passing - how the credential is used, what roles it qualifies you for, and how it affects long-term career and pay trajectories. Those questions are addressed separately in resources on TExES 235 jobs and salary outlooks, which sit alongside this meaning-focused guide on the broader site.
Turning the Meaning Into a Study Plan
Once you understand what TExES 235 actually measures - six domains weighted unevenly, with Patterns and Algebra worth nearly a third of your score - your prep schedule should reflect that weighting instead of splitting time evenly across topics. A practical approach: dedicate the largest block of study weeks to Domain II content (functions, sequences, calculus concepts), moderate blocks to Geometry and Measurement and Probability and Statistics, and shorter review passes to Number Concepts and the two process-and-pedagogy domains, which test how you reason and teach rather than isolated content recall.
Build the Algebra Core
- Functions, polynomial/rational/exponential families, and sequences (Domain II)
Geometry, Measurement, and Data
- Coordinate geometry, transformations, and statistical inference (Domains III & IV)
Number Concepts and Pedagogy
- Number systems plus mathematical processes, instruction, and assessment (Domains I, V, VI)
For a complete week-by-week plan built around this exact weighting, along with practice-question strategy and calculator drills, see TExES 235 Study Guide 2026: How to Pass on Your First Attempt. And if you're still weighing how demanding this exam really is relative to your math background, How Hard Is the TExES 235 Exam? Complete Difficulty Guide 2026 breaks that down honestly.
Whichever schedule you follow, working through full-length timed sets on our TExES 235 practice test platform is the fastest way to see which of the six domains actually needs more hours versus which ones you've already got covered. Repeating that process on the practice site a few weeks before your appointment also gets you comfortable with the CAT interface and the on-screen Definitions and Formulas page before test day.
Frequently Asked Questions
Yes. The 235 code is assigned specifically to the Mathematics 7-12 exam, meaning the certificate it produces authorizes teaching math in grades 7 through 12 in Texas public schools.
No. TExES is a Texas-specific testing program governed by TEA and SBEC. The exam code and content are tied to Texas certification standards and the TEKS, not to any national or other-state credential.
For a first Texas classroom certificate, most candidates also need to pass the PPR EC-12 (160) pedagogy exam in addition to TExES 235.
Domain II, Patterns and Algebra, at 33% weight, should get the largest share of your study time since it covers more of the scored content than any other single domain.
The exam result feeds into a standard Texas certificate, which is valid for five years and renews through ECOS with 150 CPE clock hours for classroom teachers.
