What this means: About 54% of students here test proficient in math and reading, below the roughly 68% typical for Ohio schools with a similar share of low-income students. BeatsExpectations compares each school with others at the same poverty level, not by raw scores, so a school lands here when its results trail those comparable schools, which is not the same as having low scores. A higher-scoring school can still fall in this tier if similar schools score higher still.

BeatsExpectations runs a per-state regression of proficiency on free/reduced-lunch share, then scores each school by residual. How this is calculated →

How to read these scores

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 55.0% mean for English Language Arts at Marietta High School?
It means about 55.0 percent of students tested at Marietta High 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.
Where does this data come from?
Ohio Department of Education and Workforce, Ohio School Report Cards Achievement Component. Building-level results for Ohio's State Tests (OST) in ELA + Math (grades 3-8), Science (grades 5, 8), high-school End-of-Course exams (Algebra I, Biology, English II, US History, US Government). Headline metric is the cumulative Proficient-or-Above rate (top 3 of 5 OST performance levels).
How often is it updated?
Ohio's State Tests is administered once a year (spring). Results are released by the state in the summer or early fall. We refresh this page after each annual release.
