Understanding the 1/10 Rating
SchoolDistrictFinder rates Central Islip Union Free School District 1 out of 10 — low-rated among New York public school districts. Our ratings are based on state assessment results — the share of students scoring proficient or above in reading and math, as reported in New York State’s Grades 3–8 ELA & Math assessments (2023–24 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.
Central Islip Union Free School District holds a low overall rating, with reading and math proficiency among the lowest in New York on state assessments. Test results reflect many factors beyond the classroom, including community and economic conditions; a low score is a signal to research carefully, not a verdict on any individual school or teacher. Families in this area should research all available alternatives: inter-district transfers, charter schools, and magnet programs. Contact the district directly to understand exactly what programs are available at your assigned school.
