What is Ohio's State Tests?
Ohio's State Tests (OST) are administered each spring to public-school students in grades 3 through 8 in English Language Arts and Math, plus Science at grades 5 and 8. High school students take End-of-Course exams in Algebra I, Geometry, English II, Biology, US History, and US Government for graduation.
What does "% Proficient or Above" mean?
It is the percentage of students at the school who scored at "Proficient", "Accomplished", or "Advanced" on Ohio's 5-level performance scale (Limited, Basic, Proficient, Accomplished, Advanced). Proficient and above is Ohio's grade-level benchmark; the cumulative rate is what feeds the school's Achievement Star Rating. A higher number is better.
What does 51.9% mean for English Language Arts at Hilliard Horizon Elementary School?
It means about 51.9 percent of students tested at Hilliard Horizon Elementary School performed at grade level or above on the Ohio's State Tests English Language Arts test in 2024-25. The statewide average for Ohio that year was 59.8%. The other students fell into the lower performance levels.
How is the state average calculated?
It is a weighted average, not a simple average of each school's number. We multiply each public school's score by how many of its students tested, add those together for all schools in Ohio, and divide by the total students tested that year. This way a big school with 1,500 students counts more than a small school with 50 students, which is the right way to ask "how did the typical student do this year?". District and county averages on this page use the same method, just scoped to that district or county.
