What the grade 8 SC READY math test covers
The 2026-27 blueprint sorts 50 items into four reporting categories. Measurement, Geometry, and Spatial Reasoning is the largest, 15 to 19 items: volume, the Pythagorean Theorem, angles, similar figures and transformations. Patterns, Algebra, and Functional Reasoning has 14 to 18: linear functions, slope, equations and exponents. Data, Probability, and Statistical Reasoning has 8 to 10, and Numerical Reasoning 7 to 9.
How the answers are checked
Each answer shows its steps and the indicator it practices, such as 8.MGSR.1.3, and every result is worked out again. All 39 grade 8 indicators on the blueprint have a question. Graphs and figures are described in words.
The real test opens with a No Calculator section, so work the first questions here by hand.
Questions and answers
How many questions are on the grade 8 SC READY math test?
50 operational items, each worth one point, and there may be 6 to 8 more field test items. This page also has 50 questions, all multiple choice.
Can you use a calculator on the 8th grade SC READY math test?
In the second section, yes. Grade 8 takes a No Calculator section first and then a Calculator section, where the online test provides Desmos scientific and graphing calculators.
How long is the SC READY math test in 8th grade?
No clock runs. South Carolina's format table gives 80 minutes for grades 6 to 8 only to help schools plan the day.
What is a passing score on SC READY math for grade 8?
The state names four levels and no pass mark. For 2026-27, grade 8 math scores of 273 to 296 are Approaches, 297 to 333 are Meets and 334 to 450 are Exceeds.
Is there an official SC READY practice test for math in grade 8?
The department's SC READY page describes its Online Tools Training, where students try the tools of the testing software. This page is separate and unofficial.
