SBAC 4th grade math is where California math proficiency first slips — from 46.30% at Grade 3 to 42.25% at Grade 4 — because long division, multi-digit multiplication, and equivalent fractions all show up in the same year.
Grade 4 is the year the math content widens fast. SBAC items at this grade cover multi-digit multiplication (3-digit by 2-digit) and long division (4-digit divided by 1-digit), factors and multiples within 100, prime vs. composite, equivalent fractions, comparing fractions, adding and subtracting fractions with like denominators, multiplying a fraction by a whole number, decimal notation for fractions with denominators of 10 and 100, measurement conversion within a system (km↔m, kg↔g, hr↔min), area and perimeter word problems, and angle measurement in whole-degree increments — often as a drag-the-protractor technology-enhanced item. The standards are the California Common Core State Standards: 4.OA, 4.NBT, 4.NF, 4.MD, 4.G.
42.25% of California fourth graders scored Met or Exceeded Standard on the 2024-25 SBAC Math, per CDE's October 2025 release. That is a 4.05 percentage point drop from Grade 3 (46.30%) — the first signal of a multi-year slide that bottoms out at Grade 8 (33.94%). The two biggest single skills behind the Grade 3 → Grade 4 drop are multi-digit operations using the standard algorithm and equivalent-fraction reasoning. Both reward sustained practice; neither rewards last-minute cramming.
The test format is identical to every other SBAC grade — a Computer-Adaptive Test of roughly 30 items where the engine personalizes each next question, plus a Performance Task (a multi-step real-world scenario with 4-6 connected items ending in a hand-scored written justification). ETS delivers the test on the CAASPP platform; it is untimed in California. The CAT lets your child see harder or easier items based on running performance, which means a Grade 4 student who can fluently multiply 3 × 2 digits sees more challenging items than one who is still stumbling on multi-digit multiplication.
CAASPP uses 4 achievement levels. As of the 2024-25 score reports (October 2025), the California State Board of Education renamed them: Minimal (formerly Standard Not Met), Developing (formerly Standard Nearly Met), Proficient (formerly Standard Met), and Advanced (formerly Standard Exceeded). Cut scores did not change. Proficient is the federal 'on grade level' target. Each grade has its own scale-score range; SBAC scores are vertically scaled across grades, while CAST scores are not.
SBAC's signature reporting feature is its claim-level breakdown. ELA reports four claims separately on every score report: Reading, Writing, Listening, and Research & Inquiry. Math has four claims that surface as three indicators: Concepts & Procedures, Problem Solving & Modeling/Data Analysis (claims 2 and 4 combined), and Communicating Reasoning. Each claim is flagged Above, At/Near, or Below Standard. That per-claim diagnostic is the most useful page on the score report for parents — it tells you exactly which skill to work on, not just how the child compared to a single overall cut.

SBAC Math reports three claim categories on the score report: Concepts & Procedures, Problem Solving & Modeling/Data Analysis, and Communicating Reasoning. Underneath those claims, the CA-CCSS Grade 4 blueprint puts heavy weight on Number & Operations in Base Ten (multi-digit multiplication and long division) and Number & Operations–Fractions (equivalent fractions, comparing, fraction × whole number). These two domains together typically run more than half of every form.
| Reporting Category | % of Test | What's Tested |
|---|---|---|
| Claim 1 — Concepts & Procedures | ~40% | Multi-digit multiplication using the standard algorithm, long division (4-digit ÷ 1-digit), factors and multiples within 100, prime vs. composite, equivalent fractions, comparing fractions, decimal notation for fractions with denominators 10 and 100. |
| Claim 2 + Claim 4 — Problem Solving & Modeling/Data Analysis | ~40% | Multi-step word problems, measurement conversion within a system (km↔m, kg↔g, hr↔min), area and perimeter word problems, line plots involving fractions, real-world modeling. The Performance Task lives here. |
| Claim 3 — Communicating Reasoning | ~20% | Construct and critique arguments. 'Tell whether this student's strategy for 348 × 27 is correct and explain why,' or 'Two fractions look different — explain whether they are equivalent and how you know.' |
| Content domain: Number & Operations in Base Ten (4.NBT) | — | Multi-digit multiplication using the standard algorithm (3-digit × 2-digit and smaller), long division up to 4-digit ÷ 1-digit with remainders, place value to one million, rounding. |
| Content domain: Number & Operations–Fractions (4.NF) | — | Equivalent fractions, comparing fractions with unlike numerators and unlike denominators, adding and subtracting fractions with like denominators (and mixed numbers), multiplying a fraction by a whole number, decimal notation for fractions with denominators 10 and 100. |
| Content domains: OA + MD + G (factors, conversions, angles, geometry) | — | Factors and multiples, prime vs. composite, generating number patterns; measurement conversion within a system, area and perimeter word problems, line plots; angle measurement in whole-degree increments (often a drag-the-protractor item), classifying 2-D figures by parallel/perpendicular sides. |
Multi-digit multiplication fluency is the single biggest lever at Grade 4. CA-CCSS 4.NBT.5 requires students to multiply up to 4-digit × 1-digit and 2-digit × 2-digit fluently using the standard algorithm. On the adaptive test, missing early multi-digit items drops the difficulty curve so your child never sees the harder items where they could earn Proficient-range points. Five-minute daily drills starting in winter — focus on the standard algorithm with regrouping, not just facts — pay off by April.
Long division by April. CA-CCSS 4.NBT.6 covers up to 4-digit ÷ 1-digit with remainders. Many fourth graders can multiply but freeze on long division because the steps are unfamiliar. Practice on plain paper (no calculators). Partial-quotient methods are scored as correct as long as the answer is correct, so don't force the formal algorithm if your child is comfortable with a different valid method — but make sure they have ONE method that works every time.
Equivalent fractions on a number line, not on shaded shapes. The Grade 4 fraction work — comparing 5/6 and 3/4, recognizing 1/2 = 2/4 = 3/6 = 4/8 — is faster on a number line than on cake or pizza models. Draw a long line, mark 0 and 1, and have your child plot a handful of fractions on it. Comparing becomes visual: whichever point is farther right is larger.
Use the free CDE Practice and Training Tests at caaspp-elpac.org. The protractor-drag item type (angle measurement) and the equation editor for entering numeric answers are easier to handle after 20-30 minutes of practice. The Practice Test interface is identical to test-day.
Spend 60 minutes a week on the Performance Task format specifically — not just generic word problems. The Smarter Balanced PT requires reading a real-world scenario, working through 4-6 connected steps, and explaining reasoning in writing. Free released PTs are on the Smarter Balanced Tools for Teachers site. The format is unfamiliar the first time; by the third practice PT, most fourth graders settle in.
Five California Common Core content domains: Operations & Algebraic Thinking (factors and multiples, prime vs. composite, multi-step word problems), Number & Operations in Base Ten (multi-digit multiplication, long division, place value to one million, rounding), Number & Operations–Fractions (equivalent fractions, comparing, add/subtract with like denominators, multiplying a fraction by a whole number, decimal notation for 10ths and 100ths), Measurement & Data (km↔m and kg↔g conversions, area and perimeter word problems, line plots with fractions, angle measurement), and Geometry (classify 2-D figures by parallel/perpendicular sides, recognize lines of symmetry).
Yes — long division up to 4-digit ÷ 1-digit (with remainders) is in CA-CCSS 4.NBT.6 and shows up on the test as both pure-procedure items and embedded inside word problems. Your child does not need to write out the standard long-division algorithm on every problem (partial-quotient methods are accepted in the rubric), but they do need to be able to divide accurately to find an answer. Fluency by April is the goal.
Yes, heavily. The Number & Operations–Fractions domain is one of the two heaviest weights at Grade 4 (alongside multi-digit operations). Students must: find equivalent fractions, compare fractions with unlike numerators and unlike denominators, add and subtract fractions with LIKE denominators (and mixed numbers), multiply a fraction by a whole number, and write fractions with denominators of 10 and 100 in decimal notation. Adding fractions with UNLIKE denominators is a Grade 5 skill — not assessed at Grade 4.
A multi-step real-world problem set. The student is given a scenario (planning a class trip, comparing options for a school garden, organizing a fundraiser) and works through 4-6 connected items that require calculation, modeling, and a final written justification explaining their reasoning. Expect about 60 minutes of work. The written-justification item is hand-scored by ETS-trained raters; numeric items are auto-scored.
CDE estimates about 2.5 hours total — roughly 90 minutes for the Computer-Adaptive Test and 60 minutes for the Performance Task. But the test is officially untimed in California. Schools schedule it across one or more sessions within their CAASPP window (typically March-May). Your child can take as long as the school day allows.
42.25% of California fourth graders scored Met or Exceeded Standard (the new 'Proficient' label) on the 2024-25 SBAC Math, per CDE's October 2025 release. That is down 4.05 percentage points from Grade 3 (46.30%) — the first signal of a multi-year math slide that bottoms at Grade 8 (33.94%). Statewide aggregate across all SBAC grades is 37.30%.
2,485 or higher counts as Met Standard (the new 'Proficient' label as of 2025). The full Grade 4 Math scale runs from 2,205 to 2,700. Levels are: Minimal/Standard Not Met (up to 2,410), Developing/Standard Nearly Met (2,411-2,484), Proficient/Standard Met (2,485-2,548), and Advanced/Standard Exceeded (2,549 and up). The State Board renamed levels in March 2025 — cut scores stayed the same.
No. California follows the Smarter Balanced consortium policy: calculators are not allowed at Grade 4 SBAC Math (or Grade 3 or Grade 5). Calculators first appear as an embedded tool at Grade 6. The protractor and ruler are digital tools embedded in the testing interface for geometry items, but the only allowed off-screen tool at Grade 4 is scratch paper and a pencil.
The CAT portion (~30 items, ~90 minutes) is fully computer-adaptive — the engine selects each next item from a calibrated pool based on your child's running ability estimate. Two students sitting next to each other will see different questions. The Performance Task portion (4-6 items, ~60 minutes) is NOT adaptive — every student in a given form sees the same connected items. The hand-scored written-justification item at the end of the PT is the only item that is human-rated.
