About the SBAC Math Grade 8 Exam
The Smarter Balanced Mathematics Grade 8 Summative Assessment is an online, computer-adaptive Common Core-aligned test used by member states to measure eighth-grade progress toward college and career readiness. The assessment has a computer-adaptive section and a performance task and is organized around four claims: Concepts and Procedures, Problem Solving, Communicating Reasoning, and Modeling and Data Analysis. Grade 8 content covers irrational numbers and rational approximations, integer exponents and scientific notation, proportional relationships and slope, linear equations and systems, functions, transformations and similarity, angle relationships, the Pythagorean theorem, volumes of cylinders, cones, and spheres, scatter plots, lines of best fit, and two-way tables. Results are reported on a vertical scale with four achievement levels; in CAASPP reporting, Grade 8 mathematics Level 3 begins at 2586 and Level 4 begins at 2653. The test is untimed, but Smarter Balanced estimates about 3 hours total for most Grades 6-8 mathematics students on the full form.
