Understanding the 3/10 Rating
Ossining Union Free School District has earned an overall SchoolDistrictFinder rating of 3/10, placing it in the below average tier. Our ratings are based on state assessment results — the share of students scoring proficient or above in reading and math, as reported in the U.S. Department of Education’s EDFacts collection (2021–22 school year). We average each district’s reading and math proficiency, then rank it against other districts in the same state to produce a 1–10 score. Because New York is compared only against itself, the rating reflects how this district performs relative to its in-state peers.
Ossining Union Free School District carries a below-average rating, with reading and math proficiency rates below typical New York benchmarks on state assessments. A below-average score reflects test performance relative to other districts — not necessarily teaching quality or school culture, and some of these districts have schools with strong communities and dedicated staff. Families should research specific school quality, visit in person, and ask about available programs. Also ask about open enrollment and magnet options that may offer alternatives to the default attendance-zone assignment.
