Summary

Central Islip Senior High School is a public high school serving 2,597 students in grades 9-12 in Central Islip, New York. The school is part of the Central Islip Union Free School District, which is ranked 804 out of 874 districts in the state and has a 0-star rating from SchoolDigger.

Academically, Central Islip Senior High School consistently ranks in the bottom half of New York high schools, typically between 700-800 out of 1,200-1,300 schools. Its 2-star rating from SchoolDigger indicates below-average academic performance compared to other schools in the state, with proficiency rates on Regents exams generally lower than the state and district averages, particularly in subjects like Algebra I, Geometry, and Living Environment. The school's 4-year graduation rate has fluctuated between 69.2% and 84.3% in recent years, which is below the state average, and its dropout rate has ranged from 4.5% to 6.7%, also higher than the state average.

Compared to nearby higher-performing schools like Commack High School, Smithtown High School-West, and Hauppauge High School, Central Islip Senior High School faces significant challenges, including very high chronic absenteeism rates ranging from 31.5% to 56.0%, and a high percentage of students (65.65% to 77.29%) receiving free or reduced-price lunch, indicating a high-need student population. Despite the relatively high spending per student at Central Islip Senior High School, ranging from $16,585 to $27,819 per student, the academic outcomes and other key metrics suggest the school is not effectively leveraging these resources to improve student achievement.
