Quick Facts Snapshot
Before you memorize a single formula, lock in the operational facts that shape how you prepare. TExES Mathematics 4-8 (115) is governed by the Texas Education Agency (TEA) and the State Board for Educator Certification, and it is developed and administered by Pearson through its Evaluation Systems group. The test is computer-administered at Pearson VUE centers across Texas and nationwide, and you schedule it by appointment year-round rather than during fixed windows.
| Fact | Detail |
|---|---|
| Exam fee | $116, no member/non-member tiers |
| Question count | 100 selected-response items (some unscored field-test items) |
| Total appointment time | 5 hours (15 min tutorial/agreement + 4 hrs 45 min testing) |
| Passing score | 240 on a 100-300 scale |
| Registration validity | 170 days |
| Retake wait | 30 days between attempts, 5 attempts before a waiver is needed |

Domain-by-Domain Cheat Sheet
The 2021 Mathematics 4-8 exam framework organizes content into six domains and 19 competencies aligned to Mathematics Standards I-VIII and the Texas Essential Knowledge and Skills. Here's the weighting you should keep pinned above your desk:
| Domain | Weight | Core Focus |
|---|---|---|
| 1. Number Concepts | 16% | Number systems, operations, ratios, proportional reasoning |
| 2. Patterns and Algebra | 21% | Sequences, functions, systems, pre-calculus foundations |
| 3. Geometry and Measurement | 21% | Measurement processes, proof, 2D/3D properties, transformations |
| 4. Probability and Statistics | 16% | Data representation, probability models, statistical reasoning |
| 5. Mathematical Processes and Perspectives | 10% | Problem solving, reasoning, communication, connections |
| 6. Mathematical Learning, Instruction and Assessment | 16% | Pedagogy, misconceptions, assessment design |
Notice that Domains 5 and 6 together still make up 26% of the test - nearly as much as either heavyweight domain alone. Skipping pedagogy content because it "isn't math" is a common and costly mistake. For a competency-by-competency walkthrough, the TExES 115 exam domains guide breaks down all six areas in detail.
The Two 21% Domains You Can't Skip
Patterns and Algebra and Geometry and Measurement tie for the heaviest weight on the exam, together accounting for about 42 of the 100 questions. If your remaining review time is limited, these two domains deserve first priority.
Patterns and Algebra (21%)
Covers patterns and sequences, linear and nonlinear functions, systems of equations, and the conceptual groundwork for calculus as it appears in middle-school mathematics.
- Recognize and extend numeric and geometric patterns, then generalize them algebraically
- Compare linear vs. nonlinear function behavior using tables, graphs, and equations
- Solve and interpret systems of equations in real-world contexts
- Connect rate of change and accumulation to early calculus-style reasoning
Geometry and Measurement (21%)
Covers measurement as a process, Euclidean relationships and proof, properties of two- and three-dimensional figures, and transformational/coordinate geometry.
- Apply measurement units, precision, and conversion across contexts
- Construct and justify simple geometric proofs and relationships
- Classify and compare properties of polygons, polyhedra, and circles
- Perform and describe translations, reflections, rotations, and dilations on a coordinate plane

Test-Day Format and Tools
Knowing the mechanics of the testing room removes one entire category of exam-day anxiety. TExES 115 is a computer-administered test (CAT), and every candidate gets the same built-in tools - nothing you bring from home is allowed to substitute for them.
- Calculator policy: Personal calculators are prohibited for this test code. An on-screen scientific calculator is provided within the testing software.
- Reference material: A Definitions and Formulas page is available on-screen throughout the test - learn its contents ahead of time so you use it for lookup, not learning.
- Question format: All 100 questions are selected-response; some are unscored field-test items mixed in, but only scored questions count toward your final scaled score.
- Time budget: The full appointment runs 5 hours - 15 minutes for the tutorial and compliance agreement, then 4 hours 45 minutes of actual testing time.
Key Takeaway
Practice using an on-screen scientific calculator before test day so its layout doesn't slow you down during timed sections - muscle memory with a physical calculator won't transfer directly.
Registration and Retake Logistics
Eligibility and scheduling rules matter as much as content knowledge, since a missed deadline or forgotten waiver can derail an otherwise solid preparation plan.
- You must be approved to test by an educator preparation program or by TEA before you can register.
- Registration is valid for 170 days from the date you register.
- Withdrawing from an appointment refunds the exam fee minus a $25 processing charge.
- You get five attempts total, with a mandatory 30-day wait between each attempt; a sixth attempt requires a TEA test-limit waiver.
- Scores post at 10:00 p.m. Central on the published score report date - not immediately after testing.
For candidates weighing timing against other program deadlines, the exam dates and scheduling guide and the eligibility requirements breakdown cover the prerequisites in more depth. If budgeting is your main concern, the certification cost breakdown lays out every fee you'll encounter along the way.
Final-Week Review Plan
A short, domain-weighted schedule works better than an unfocused cram in the last days before your appointment. Anchor your remaining hours to the domains carrying the most points.
Patterns and Algebra + Geometry and Measurement
- Rework missed practice items from both 21% domains
- Redo one full-length timed set focused only on these two areas
Number Concepts + Probability and Statistics
- Review ratio, proportion, and data-interpretation item types
- Drill the Definitions and Formulas page so lookups are fast, not distracting
Processes, Perspectives, and Pedagogy
- Review problem-solving and communication competencies (Domain 5)
- Practice instructional-scenario questions from Domain 6
Full Simulation
- Take one complete timed practice test at the main practice test platform
- Review flagged items using the on-screen calculator and formulas page just as you would on test day
Running at least one full-length simulation under real time constraints at the practice site before your appointment is the single best way to confirm your pacing holds up across all 100 questions.
What Happens After You Pass
Passing at 240 or above is only one step in a longer certification and career path. Texas standard certificates are valid for five years and renew through ECOS with 150 CPE clock hours for classroom teachers, so this exam is the start of an ongoing professional cycle, not a one-time hurdle.
If you're still deciding whether the investment of time and fees is worth it relative to career outcomes, the ROI analysis and salary guide lay out the qualitative case, and the jobs overview covers where math-certified 4-8 teachers typically get hired. For a broader look at how your results compare statewide, the pass rate analysis uses the TEA's published 2024-2025 program-year figures.
FAQ
There are 100 selected-response questions, some of which are unscored field-test items. Your total appointment is 5 hours, including a 15-minute tutorial and compliance agreement plus 4 hours 45 minutes of testing.
No. Personal calculators are prohibited for this test code. You'll use an on-screen scientific calculator provided within the exam software, along with an on-screen Definitions and Formulas page.
Patterns and Algebra and Geometry and Measurement each carry 21%, tying for the heaviest weight and together representing about 42 of the 100 questions.
You need a scaled score of 240 out of a 100-300 range. You get five attempts with a required 30-day wait between each; beyond five attempts you need a TEA test-limit waiver.
Not by itself. A first Texas classroom certificate also typically requires passing the PPR EC-12 (160) pedagogy exam in addition to TExES Mathematics 4-8 (115).
