Summary:

The Ossining Union Free School District in New York serves students from pre-kindergarten through 12th grade across 6 schools, including 3 elementary schools, 2 middle schools, and 1 high school.

Among the standout schools in the district, Anne M Dorner Middle School has the highest proficiency rates on the New York State Assessments, particularly in math, where 50.58% of 7th graders were proficient in 2024-2025, compared to 50.44% for the district and 56.47% for the state. Ossining High School also has strong performance metrics, with 85.71% proficiency in Regents Algebra II in 2024-2025, significantly higher than the district (85.71%) and state (74.88%) averages.

However, the Ossining Union Free School District as a whole is ranked 720 out of 874 districts in New York and is rated 1 out of 5 stars by SchoolDigger, indicating significant challenges in providing high-quality education across all its schools. The district serves a predominantly low-income population, with the percentage of students receiving free or reduced-price lunch ranging from 43.31% at Park School to 57.81% at Anne M Dorner Middle School, raising concerns about equity and the ability to provide equal educational opportunities.
