TExES Math 7-12 (235) Practice Test — Adaptive Prep
Targeted, adaptive preparation for the Texas Examinations of Educator Standards (TExES) Mathematics 7-12 certification exam, test code 235. Item Response Theory placement, question distribution that mirrors the Texas Education Agency competency framework, and a 90-day pass-or-refund guarantee.
What the TExES 235 covers
The TExES Math 7-12 (235) is a computer-administered, 100-question exam. You have five hours, but most test-takers finish in roughly three and a half. The exam is organized into six competency-aligned domains set by the Texas Education Agency and reviewed by Texas Educator Certification Examination Program.
TEA competency domains
The passing standard is set by the State Board for Educator Certification. As of the current administration, the passing scaled score is 240 on a 100–300 scale, which corresponds to roughly 60% raw correct.
How adaptive prep is different
The standard TExES 235 review approach — a 500-page study guide plus a static question bank — treats every test-taker identically. You re-do material you already know, and you still hit the exam surprised by topics you skimmed. The result is the long average prep cycle (3–5 months) most candidates report, and the roughly 40% first-attempt fail rate the TEA publishes.
QuantegyAI uses Item Response Theory — the same statistical model the real exam vendors use — to estimate your skill on each of the six TEA domains independently. Every answer updates the model. The next question is drawn from your upper bound of mastery: just hard enough to confirm or revise the estimate. After about 30 placement questions, you have a calibrated ability estimate per domain and a personalized study plan that tells you exactly where to spend your prep hours.
What's in the question bank
- 2,000+ practice questions, every one authored or vetted by a working mathematician
- Full alignment to the TEA competency framework — question metadata maps to domain and sub-competency
- Worked explanations on every question, not just an answer key
- 40+ interactive review widgets that let you manipulate algebra tiles, build statistical displays, explore geometry, and more
- Full-length mock exams with score reports broken down by domain
- Progress sync across devices so you can study on your laptop and review on your phone
Who built this
QuantegyAI was built by Dr. Mienie Roberts, a mathematics professor and an active reviewer for the Texas Instructional Materials Review and Approval (IMRA) process. The question bank, the adaptive engine, and every review widget are built in-house — not licensed from a third-party generator.

Frequently asked questions
Is this the same exam as the older TExES Math 7-12 (135)?
No. The 135 was retired in 2018 and replaced by the 235, which has updated competency descriptors and a larger pedagogy domain. Our question bank targets the current 235 framework.
How long should I prepare?
For test-takers coming directly out of an undergraduate math major, 6–10 weeks of consistent adaptive practice (3–5 sessions per week, 30–45 minutes each) is typical. The placement test on day one gives you a calibrated estimate of how far you are from passing.
Does QuantegyAI also cover the supplemental Pedagogy and Professional Responsibilities (PPR) exam?
No. The 235 only assesses mathematics content and pedagogical content knowledge — not the general PPR. We focus on what we do well.
Can I take the placement test before I buy?
Yes. The placement test is free and gives you a calibrated estimate of your current ability on every TEA domain, plus a recommended prep length. You only pay when you start the full adaptive practice loop.
