Central Islip Senior High School stands out in several key ways. It has a significantly higher percentage of Hispanic students (81.41%) compared to nearby schools like Commack High School, Islip High School, and East Islip High School, which tend to have more diverse racial compositions or higher percentages of white students. Additionally, Central Islip Senior High School has seen a decline in its four-year graduation rates, dropping from 89.5% in 2019-2020 to 72.2% in 2022-2023, which is lower than the graduation rates of nearby high-performing schools.

Other concerning trends at Central Islip Senior High School include an increase in dropout rates, from 0.9% in 2019-2020 to 6.4% in 2022-2023, as well as a very high chronic absenteeism rate of 54.1% in 2022-2023, which is much higher than the rates of nearby schools. The school's performance on Regents exams is also generally lower than the district and state averages, with proficiency rates ranging from 41.58% in Geometry to 77.51% in U.S. History and Government. These academic challenges may be related to the high percentage of students from low socioeconomic backgrounds, with 77.29% of students qualifying for free or reduced-price lunch in 2022-2023.

As you review the school rankings data, please be aware that some of the information from certain demographics is missing. The reason for this omission is that the data has been redacted from the source data itself due to low population samples in these specific demographic groups.

Redacting data from low population samples is a necessary step to ensure the reliability and accuracy of the results, as small sample sizes may not be representative of the broader population. Additionally, this measure helps protect the privacy of individuals belonging to these demographic groups.

About Students eligible for discounted/free lunch:

The National School Lunch Program (NSLP) provides low-cost or free meals to students in U.S. public and nonprofit private schools based on household income. Those with incomes below 130% of the poverty line receive free lunch, while those between 130% and 185% qualify for reduced-price lunch. The percentage of students receiving free or reduced-price lunch serves as a marker for poverty, as it reflects the socioeconomic status of families in a given school or district. A higher FRPL rate typically indicates a higher concentration of low-income families, suggesting that the school or district may face additional challenges in providing adequate resources and support for student success.

About Student-Teacher Ratio

Student/teacher ratio is calculated by dividing the total number of students by the total number of full-time equivalent teachers. Please note that a smaller student/teacher ratio does not necessarily translate to smaller class size. In some instances, schools hire teachers part time, and some teachers are hired for specialized instruction with very small class sizes. These and other factors contribute to the student/teacher ratio. Note: For private schools, Student/teacher ratio may not include Pre-Kindergarten.
