STAAR 8th grade math is the FIRST year a graphing calculator is allowed (and required), the bridge to Algebra I EOC, and one of two grades where HB 4545 entitles your child to accelerated instruction if they don't reach Approaches.
Grade 8 STAAR Math is two big firsts at once. FIRST: a graphing calculator is REQUIRED — the only year on STAAR Math that's true. Districts must provide either a handheld graphing calculator, an approved app on a district-provided device, or the TDS embedded online graphing calculator built into Cambium's platform. CAS calculators are allowed only with CAS disabled. SECOND: Grade 8 is the bridge to the Algebra I End-of-Course (EOC) exam — many Texas eighth graders take Algebra I and the EOC at the same time, and the Grade 8 Math TEKS deliberately previews Algebra I content.
Grade 8 is also one of two grades — alongside Grade 5 — where HB 4545 entitles students who don't reach Approaches Grade Level on STAAR Math or RLA to accelerated instruction (30 hours per subject per year, in groups of 3 or fewer, with a qualified educator) and a retest opportunity. The accelerated-instruction obligation is statutory.
Content: linear functions and equations, Pythagorean theorem, transformations (translations, rotations, reflections, dilations), scatter plots and trend lines, volume of cylinders, cones, and spheres, scientific notation, and exponential rules. Reporting categories: Numerical Representations and Relationships (2-4 items, the smallest), Computations and Algebraic Relationships (15-17 items, the heaviest), Geometry and Measurement (14-16 items, second-heaviest), and Data Analysis & PFL (5-7 items). Spring 2024: 70% Approaches, 40% Meets. Format: 40 items (32 one-point + 8 two-point) = 48 raw points. Scale score range: roughly 1240-2470. No STAAR Spanish version (Spanish caps at Grade 5).
Under Texas HB 4545, students in Grade 5 or Grade 8 who don't reach Approaches Grade Level on STAAR Math or RLA are entitled to accelerated instruction (30 hours per subject per year, in groups of 3 or fewer, with a qualified educator) and a retest opportunity within the testing window. Promotion is no longer blocked under post-SSI policy — but the accelerated-instruction requirement is statutory and the school must provide it.
Spring 2026 is the final pre-replacement STAAR window. The Texas Legislature passed HB 4 in 2025 replacing STAAR with the 'Student Success Tool' (SST) — three shorter check-in assessments spread across the school year — starting in 2027-28. Spring 2026 and Spring 2027 are the last two STAAR administrations Texas students will sit. The new SST is built around through-year testing, not a single high-stakes spring window.
STAAR uses 4 performance levels: Did Not Meet Grade Level, Approaches Grade Level (Texas's 'passing' standard), Meets Grade Level (federal 'on grade level' target), and Masters Grade Level (advanced). 'Approaches' counts as passing for promotion; 'Meets' is the grade-level proficiency target most parents care about.
Approaches Grade Level = 70%. Grade 8 sits in the middle of the STAAR 3-8 math pack — above Grade 6 (37%) and Grade 7 (32%) but below Grade 5 (48%).

Which equation represents a line with slope 3 and y-intercept −2?
TEKS Grade 8 Math is dominated by Computations & Algebraic Relationships (15-17 items, 5 Readiness + 9 Supporting standards) and Geometry & Measurement (14-16 items, 5 Readiness + 9 Supporting). Together these two categories account for roughly 60-70% of the test. Numerical Representations & Relationships is unusually small at just 2-4 items. Data Analysis & PFL runs 5-7 items.
| Reporting Category | % of Test | Items | What's Tested |
|---|---|---|---|
| Numerical Representations and Relationships | ~4-10% | 2-4 items | Smallest Grade 8 category. Scientific notation (representing very large and very small numbers), approximating irrational numbers and locating them on a number line, classifying real numbers (rational vs. irrational), and ordering rationals across forms. |
| Computations and Algebraic Relationships | ~35-46% | 15-17 items | Heaviest Grade 8 category. Linear functions (slope, y-intercept, slope-intercept form y = mx + b, point-slope form), one-variable linear equations and inequalities with rational coefficients, systems of two linear equations, functions vs. relations (vertical-line test, function notation), and exponential rules (product, quotient, power, negative exponents). This is the Algebra I bridge content. |
| Geometry and Measurement | ~31-42% | 14-16 items | Pythagorean theorem and its converse (find missing leg or hypotenuse), transformations (translations, rotations, reflections, dilations — with coordinate-plane representations), angle relationships in parallel lines cut by a transversal (alternate interior, corresponding, etc.), volume of cylinders/cones/spheres (using π), and similarity transformations connecting Grade 7 similar figures to Grade 8 dilations. |
| Data Analysis and Personal Financial Literacy | ~10-19% | 5-7 items | Scatter plots and trend lines (line of best fit), bivariate data interpretation, mean absolute deviation continued from Grade 7. Plus Texas-specific PFL: methods of paying for college (including dual credit, AP credit, financial aid), advantages of post-high-school education, types of investment accounts. |
Grade 8 STAAR Math is three Texas-specific firsts at once. FIRST: a graphing calculator is REQUIRED — the only STAAR Math grade where that's true. Districts must provide a handheld graphing calculator, an approved app, or the TDS embedded online graphing calculator. CAS calculators are allowed only with CAS DISABLED. SECOND: Grade 8 is the bridge to STAAR Algebra I EOC. The Grade 8 Math TEKS deliberately previews Algebra I content — linear functions, systems of equations, function notation, exponential rules — and many Texas eighth graders take both STAAR Grade 8 Math AND STAAR Algebra I EOC in the same spring. THIRD: Grade 8 is one of two grades (with Grade 5) where HB 4545 entitles students who don't reach Approaches Grade Level to 30 hours of accelerated instruction per subject per year (in groups of 3 or fewer, with a qualified educator) and a retest opportunity. Promotion to Grade 9 is not automatically blocked under current post-SSI policy, but the accelerated-instruction obligation is statutory. And the bigger picture: Spring 2026 is one of the last two STAAR administrations — the Student Success Tool replaces STAAR starting 2027-28 under HB 4 (passed 2025). The HB 4545 accelerated-instruction right transfers to the SST, but Grade 8's role as the STAAR Algebra I EOC bridge may shift under the new system.
Familiarize your child with the graphing calculator BEFORE test day. Grade 8 is the FIRST year on STAAR Math where a calculator is allowed — and required. Most eighth graders have used a basic calculator but haven't used a graphing calculator's table, graph, or solver functions. Spend 30 minutes a week from January through March practicing: graph y = mx + b, use the table feature to find x-y pairs, solve equations with the solver, find regression lines for scatter plots. The TDS embedded online graphing calculator on Cambium's platform is free to practice with through TEA-released tests.
Linear functions is the single highest-leverage Grade 8 skill. Computations & Algebraic Relationships carries 15-17 items (35-46% of the test), and linear functions dominate the category. Daily 10-minute practice on slope, y-intercept, slope-intercept form, and graphing linear equations from January through March moves Computations points reliably. This is also the foundation skill for Algebra I EOC.
Know the HB 4545 right and ask for it. Grade 8 is one of two grades (with Grade 5) where HB 4545 entitles students who don't reach Approaches Grade Level to 30 hours of accelerated instruction per subject per year, in groups of 3 or fewer, with a qualified educator. The school must provide it. Many parents don't know this. Ask the campus assessment coordinator: 'What accelerated-instruction plan does my child qualify for under HB 4545 if they don't reach Approaches?'
Practice Pythagorean theorem until it's automatic. Pythagorean theorem appears repeatedly in Geometry & Measurement items (14-16 items total, second-heaviest category). Practice both finding the hypotenuse (a² + b² = c²) and finding a missing leg (rearranged to b² = c² - a²). Real-world applications — ladder problems, diagonal distances, right-triangle navigation — appear in two-point items.
Treat Grade 8 STAAR as the Algebra I EOC on-ramp. Grade 8 Math TEKS deliberately previews Algebra I. Strong Grade 8 performance in Computations & Algebraic Relationships directly predicts Algebra I EOC readiness. Use the Grade 8 reporting-category breakdown in the TexasAssessment.gov family portal to identify gaps before Algebra I starts (or, if your child is already in Algebra I, to identify which Grade 8 standards need quick review before the EOC).
A graphing calculator. Districts must provide one of three options: (1) a handheld graphing calculator (TI-83/84 family, or comparable), (2) an approved graphing-calculator app on a district-provided device, or (3) the TDS embedded online graphing calculator built into Cambium's testing platform. CAS calculators (TI-Nspire CAS, HP Prime, etc.) are allowed only with CAS functionality DISABLED. Your child does not bring their own — the district must provide. See TEA's 2026 STAAR Calculator Policy and TI's Knowledge Base entry on TEA calculator policy.
40 scored items per ESC Region 13's 2024-25 blueprint summary (32 one-point + 8 two-point = 48 raw points). The 2024 Raw Score Conversion Table at tea.texas.gov gives the exact raw-to-scale-score mapping for Approaches/Meets/Masters cut scores. Field-test items also appear on the operational form but don't count toward your child's score.
The scale-score range for Grade 8 Math runs approximately 1240-2470 (per blueprint-derived value from the 2024 raw-score conversion table). 48 raw points is the maximum. The four performance levels — Did Not Meet, Approaches, Meets, Masters — each have a cut score on the scale. Masters Grade Level is the advanced tier. The Spring 2024 Masters rate for Grade 8 Math was not in TEA's press-release breakdown — pull the statewide-summary PDF at tea.texas.gov for the exact figure.
Major content areas: linear functions and equations (slope, y-intercept, slope-intercept form), one-variable linear equations and inequalities, systems of two linear equations, functions vs. relations (vertical-line test, function notation), Pythagorean theorem and its converse, transformations (translations, rotations, reflections, dilations) in the coordinate plane, scatter plots and lines of best fit, volume of cylinders/cones/spheres, scientific notation, exponential rules, angle relationships in parallel lines, and Texas-specific PFL (methods of paying for college, types of investment accounts).
No. STAAR Spanish caps at Grade 5 in Math and RLA. Grade 8 has no Spanish version of any subject. Emergent bilingual students at Grade 8 use the English-only STAAR with allowable linguistic accommodations as determined by the LPAC (Language Proficiency Assessment Committee).
STAAR has a 4-hour standard time limit per subject, with up to 7 hours maximum for students who need extended time within the same school day. Administration is online through Cambium's TDS platform within a statewide 2-week testing window each spring — typically early-to-mid April for Math.
Four priorities. (1) Linear functions and equations — slope, y-intercept, slope-intercept form y = mx + b. Daily practice on graphing linear equations and identifying slope from tables, graphs, and equations moves Computations points reliably. (2) Pythagorean theorem applications — both finding the hypotenuse and finding a missing leg. (3) Transformations on the coordinate plane — translations, rotations, reflections, dilations. (4) Systems of two linear equations — solving by graphing, substitution, and elimination. These are the same skills tested on Algebra I EOC.
Under HB 4545, if your child doesn't reach Approaches Grade Level, they're entitled to accelerated instruction — 30 hours per subject per year, in groups of 3 or fewer students, with a qualified educator — and a retest opportunity within the testing window. Promotion to Grade 9 is NOT automatically blocked under current post-SSI policy, but the accelerated-instruction obligation is statutory. For students taking Algebra I + EOC at Grade 8, the EOC also counts toward graduation requirements — Grade 8 STAAR Math failure is a separate issue from EOC failure.
Yes — directly. The Grade 8 Math TEKS deliberately previews Algebra I content: linear functions and equations, systems of equations, function notation, exponential rules, and Pythagorean theorem all appear on both tests. Many Texas eighth graders take Algebra I as a course at Grade 8 and sit for both STAAR Grade 8 Math AND STAAR Algebra I EOC in the same spring. Strong Grade 8 Math performance — especially in Computations & Algebraic Relationships — is the leading indicator for Algebra I EOC readiness.
