About the OST Grade 5 Math Exam
The Ohio State Test (OST) in Mathematics for Grade 5 measures how well fifth graders have mastered Ohio's Learning Standards for Mathematics (2017). The test is built around three reporting categories defined in the official blueprint: Fractions (33-43% of the test), Decimals (33-43%), and Geometry (21-27%). Fifth-grade content emphasizes operations with decimals, multiplying and dividing fractions, volume of rectangular prisms, the first-quadrant coordinate plane, order of operations with parentheses, and converting measurement units. The test is administered online in the spring in two parts totaling about 150 minutes, using multiple-choice and technology-enhanced items, with a reference sheet of measurement conversions available to students. Results are reported on a scale where 700 is Proficient and 725 (Accomplished) signals readiness for the next grade.
