Turn your study time into focused preparation
The TExES Mathematics 4-8 covers a broad range of mathematical concepts and teaching knowledge — but every candidate starts from a different place. You may already be confident in some areas while needing significantly more preparation in others. QuantegyAI identifies those differences before you decide where to spend your study time, so every session targets the competencies that will actually move your score.
About the TExES Math 4-8 (115)
The TExES Mathematics 4-8 (115) certifies teachers to teach math in grades 4 through 8 in Texas public schools. The exam has 90 scored questions and a 5-hour time limit; most test-takers finish in roughly 3 hours. The passing scaled score is 240 on a 100–300 scale, set by the State Board for Educator Certification (SBEC).
Unlike the 7-12 (235), the 4-8 does not test calculus or advanced number theory. Instead, it goes deep on middle school content — fractions, ratios, linear functions, geometry, statistics — and devotes 28% of the exam to how students learn mathematics and how to assess that learning. Many candidates underestimate the pedagogy domains (D5 and D6) and fail on them.
TEA competency domains
Looking for a TExES Math 4-8 study guide?
A study guide can help you understand the content. Practice questions are useful. But answering question after question isn’t the most effective way to prepare if you don’t know which areas are holding you back. Start by answering one important question: what do you actually need to study? The free diagnostic establishes your starting point; from there, QuantegyAI moves you beyond generic preparation and builds your practice around your individual gaps — targeted questions, worked explanations, mock exams, and progress tracking toward exam readiness.
How adaptive prep is different
Most TExES 4-8 prep stops at a static question bank and a study guide. You work through material in order, re-reading chapters on topics you already know and moving too fast past topics where you have real gaps. The result is wasted hours and a score that stalls.
QuantegyAI uses Item Response Theory — the same statistical model the real exam vendors use — to estimate your ability 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. The Quick Diagnostic takes 12 questions to find your initial gaps and start your readiness estimate. Calibration continues as you practise, so the estimate becomes increasingly precise and your personalized study plan keeps adapting. that tells you exactly where your prep hours will have the most impact.
Scores update after every question — not at the end of a session. You can see your pass probability in real time as you work, which is something no static prep product does.
What’s in the question bank
- 2,100+ calibrated questions aligned to the TEA 4-8 competency framework
- Full coverage of all six domains including the pedagogy-heavy D5 and D6
- Worked explanations on every question — not just an answer key
- 40+ interactive review widgets covering algebra tiles, number lines, coordinate planes, geometric transformations, and statistical displays
- Full-length mock exams with score reports broken down by domain
- Real-time IRT score updates after every question so you always know where you stand

Built by a mathematics professor
QuantegyAI was built by Dr. Mienie Roberts, a mathematics professor and active reviewer for the Texas Instructional Materials Review and Approval (IMRA) process. The question bank, adaptive engine, and every review widget are built in-house — not licensed from a third-party generator. Dr. Mienie has a 100% pass rate among the students she has personally tutored over the past 5 years.1 The idea behind QuantegyAI is simple: understand what you know, identify what you don’t, and focus on what comes next.
1. Pass rate refers to certification-exam outcomes for students Dr. Mienie Roberts personally tutored during the past 5 years. Documented evidence is kept on file and available to institutional and procurement reviewers on request.

Frequently asked questions
How many questions are on the TExES Math 4-8 (115)?
The exam has 90 scored questions and a 5-hour time limit. Most test-takers finish in roughly three hours. The exam is organized into six competency-aligned domains set by the Texas Education Agency.
What is the passing score?
The passing scaled score is 240 on a 100–300 scale, set by the State Board for Educator Certification. This corresponds to roughly 60% raw correct.
Is the TExES 4-8 harder than the TExES 7-12?
The 4-8 is narrower in advanced mathematics (no calculus, no complex numbers) but devotes 28% of its weight to pedagogy — how students learn and how to assess learning. Many retakers who have strong content knowledge still fail on the D5/D6 pedagogy domains. The 7-12 is more mathematically demanding at the upper end; the 4-8 is more demanding in pedagogical content knowledge.
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.
How long should I prepare?
For education majors with solid grade 4-8 content knowledge, 4–8 weeks of consistent adaptive practice (3–5 sessions per week, 30–45 minutes each) is typical. The placement test gives you a personalized estimate on day one.
Does QuantegyAI cover both TExES 4-8 and 7-12?
Yes. Both exams share the same adaptive engine and question pool infrastructure. If you hold or are pursuing multiple certifications, your progress on each exam tracks separately.
