What "TExES 115" Actually Refers To
"TExES 115" is shorthand for the TExES Mathematics 4-8 (115) exam - one of dozens of subject-specific tests inside the Texas Examinations of Educator Standards (TExES) system. The number 115 is simply the test code that the Texas Education Agency (TEA) and the State Board for Educator Certification assigned to this particular math content exam. It has nothing to do with grade point averages, credit hours, or any other credential that happens to share a similar-sounding number elsewhere. In Texas, if you want to teach mathematics to students in grades four through eight, TExES 115 is the content exam that verifies you know the subject matter well enough to be trusted in front of a classroom.
The exam is developed and administered by Pearson (Evaluation Systems) on behalf of TEA, delivered as a computer-administered test (CAT) at Pearson VUE testing centers throughout Texas and, by appointment, nationwide. It is not a paper-and-pencil exam, and it is not scheduled around a handful of fixed dates a year - you book an appointment when you're ready, subject to the availability windows covered in our TExES 115 exam dates guide.
Who Takes This Exam and Why
TExES 115 exists for one narrow but important purpose: certifying middle-grades math instruction in Texas public schools. The people who sit for it generally fall into a few buckets:
- Candidates finishing a university-based educator preparation program (EPP) who need the content exam before their preparation program will recommend them for certification.
- Career-changers going through alternative certification programs who are adding a mathematics 4-8 credential.
- Certified teachers in another grade band or subject who want to add middle school math to their existing certificate.
- Out-of-state or out-of-country educators pursuing Texas reciprocity who still need to demonstrate content knowledge on Texas's own exam.
Regardless of pathway, no one can simply walk up and register. You must be approved to test either by your educator preparation program or directly by TEA - there's no open, first-come registration. If you're unsure whether you meet that threshold, our TExES 115 requirements guide breaks down eligibility and prerequisites in more detail.
Districts hiring for grades 4-8 math positions - middle school math teachers, some intermediate/elementary math specialists in departmentalized 4th-5th grade settings, and math intervention roles - all look for this specific certification on a candidate's credential file.

Exam Format, Fees, and Registration Mechanics
TExES 115 is built around 100 selected-response questions covering grades 4-8 mathematics content. Some of those questions are unscored field-test items TEA uses to evaluate future exam material - you won't know which ones, so every question deserves your full attention, but only the scored items count toward your final result.
Your total appointment runs 5 hours: the first 15 minutes cover the CAT tutorial and a compliance agreement, followed by 4 hours and 45 minutes of actual testing time. That's a long sitting, and pacing matters - a topic we unpack more thoroughly in our TExES 115 difficulty guide.
- Exam fee: $116, flat - no member or non-member pricing tiers.
- Registration validity: 170 days from the date you register.
- Withdrawal refund: the exam fee minus a $25 processing charge if you withdraw before testing.
- Attempt limit: five attempts total, with a mandatory 30-day wait between each attempt; beyond five attempts you need a TEA test-limit waiver.
- Tools provided on-screen: a Definitions and Formulas reference page and a scientific calculator built into the testing software.
- Personal calculators: not permitted for this test code - you must use the on-screen tool only.
Full cost breakdowns, including how this fee fits into total certification spending, live in our TExES 115 certification cost guide.
Key Takeaway
Because personal calculators aren't allowed, practice exclusively with the on-screen scientific calculator style tools before test day - familiarity with its layout under time pressure matters more than raw calculator skill.
The Six Domains Explained
Content on TExES 115 is organized around the 2021 Mathematics 4-8 exam framework, which defines 19 competencies spread across six domains, all aligned to the Mathematics Standards I-VIII and the Texas Essential Knowledge and Skills (TEKS). For a full competency-by-competency walkthrough, see our TExES 115 exam domains guide.
Domain 1: Number Concepts (16%)
Covers number sense, place value, operations, ratios, proportional reasoning, and the number theory that underpins later algebra work.
- Fluency with fractions, decimals, and percents across representations
Domain 2: Patterns and Algebra (21%)
The heaviest-weighted domain alongside Geometry and Measurement. Focuses on patterns and sequences, linear and nonlinear functions, systems of equations, and the conceptual groundwork for calculus that shows up in middle school topics.
- Expect multi-step function and equation reasoning questions
Domain 3: Geometry and Measurement (21%)
Tied for the top domain weight. Includes measurement as a process, Euclidean relationships and proof, properties of two- and three-dimensional figures, and transformational and coordinate geometry.
- Proof-based reasoning items appear alongside applied measurement problems
Domain 4: Probability and Statistics (16%)
Covers data representation, measures of center and spread, probability models, and statistical inference appropriate to middle-grades instruction.
- Interpretation questions often pair data displays with real-world scenarios
Domain 5: Mathematical Processes and Perspectives (10%)
Tests reasoning, problem-solving strategies, mathematical communication, and connections across mathematical topics rather than a single content strand.
- Often tests whether you can justify a method, not just execute it
Domain 6: Mathematical Learning, Instruction and Assessment (16%)
Focuses on pedagogy specific to math: how students develop mathematical understanding, instructional strategies, and how to assess learning appropriately.
- Blends content knowledge with classroom application scenarios
Because Patterns and Algebra and Geometry and Measurement each carry 21% weight, roughly 42 of the 100 questions come from those two domains combined - meaning strong performance there disproportionately affects your final scaled score. Anyone building a study plan should weight time accordingly, a point we return to below and expand on in the TExES 115 study guide.
| Domain | Weight | Approx. Questions |
|---|---|---|
| Number Concepts | 16% | ~16 |
| Patterns and Algebra | 21% | ~21 |
| Geometry and Measurement | 21% | ~21 |
| Probability and Statistics | 16% | ~16 |
| Mathematical Processes and Perspectives | 10% | ~10 |
| Mathematical Learning, Instruction and Assessment | 16% | ~16 |
How the Exam Is Scored
Scores are reported on a scale of 100 to 300, and the passing score is 240. Every scored question contributes to that scaled result, but because some field-test items are unscored, you can't reverse-engineer your score from a simple percentage of items answered correctly - the scaling formula accounts for question difficulty. Our TExES 115 passing score guide walks through exactly what 240 means in practice and how close a "just missed it" result usually is.
Scores post at 10:00 p.m. Central on the officially published score report date for your test window - not immediately after you finish. If you don't pass, the required 30-day wait before your next attempt gives you time to target the specific domains where your score report shows weakness, rather than re-studying everything from scratch.
For a statewide sense of how candidates actually perform on this exam, our TExES 115 pass rate breakdown covers the numbers TEA has published for recent program years.
How to Prepare, Week by Week
A generic study calendar won't help much here - the plan should follow the domain weights. Since Patterns and Algebra and Geometry and Measurement together make up 42% of the exam, they deserve the largest blocks of dedicated review time, while Mathematical Processes and Perspectives (10%) needs less standalone time and can often be reinforced while reviewing other domains.
Number Concepts + diagnostic
- Take a full-length practice set to identify weak competencies
- Review ratios, proportional reasoning, and number theory fundamentals
Patterns and Algebra
- Drill linear/nonlinear function reasoning and systems of equations
- Practice translating word problems into algebraic models
Geometry and Measurement
- Work proof-based items and coordinate/transformational geometry
- Practice measurement problems using only the on-screen calculator
Probability, Statistics, and Processes
- Review data interpretation and probability models
- Practice justifying solution methods in writing, mirroring Domain 5
Instruction/Assessment + full simulation
- Study math-specific pedagogy scenarios from Domain 6
- Take a timed, full-length simulation under 5-hour conditions

After You Pass: Certification Path
Passing TExES 115 confirms your math content knowledge, but it's typically one piece of a larger certification puzzle. Most first-time Texas certification candidates also need to pass the PPR EC-12 (160) pedagogy exam, since content knowledge and pedagogical practice are certified separately in Texas. Once both are complete and your educator preparation program or TEA finalizes your application, you receive a standard certificate valid for five years.
Renewal happens through TEA's ECOS system, and classroom teachers must log 150 CPE clock hours during that five-year cycle to renew. This is worth planning for early rather than scrambling in year four. For a fuller picture of what the certification unlocks and what current classroom teachers can expect, see our TExES 115 salary guide and the general TExES 115 certification overview.
