Summary

Seneca Middle School is a public middle school located in Holbrook, New York, serving grades 6-8 with a total enrollment of 974 students. It is part of the Sachem Central School District, which is ranked 524 out of 874 school districts in New York and has a 2-star rating from SchoolDigger.

Seneca Middle School has had a mixed academic performance compared to the state and district averages. While it has performed well in some subject areas and grade levels, such as 7th grade math and 8th grade science, it has struggled in others, particularly in English Language Arts (ELA) across all grade levels. For example, in the 2024-2025 school year, the percentage of students proficient or better in ELA ranged from 28.4% in 6th grade to 40.63% in 7th grade, compared to the state averages of 50.86% and 50.99% respectively. Additionally, the school's performance varies significantly across different student subgroups, with Asian and White students generally performing better than the state averages, while Hispanic and economically disadvantaged students have struggled, with their performance often ranking in the bottom quartile of New York middle schools.

Seneca Middle School's performance is generally lower than that of nearby middle schools in the Sachem Central School District, such as Samoset Middle School and Sagamore Middle School, which have higher academic achievement and better student group performance. Additionally, Seneca Middle School's performance has declined over the years, with its statewide ranking dropping from 315 out of 1,439 New York middle schools in the 2018-2019 school year to 843 out of 1,500 in the 2024-2025 school year. The school has also seen a significant increase in per-student spending, from $15,339 in the 2020-2021 school year to $30,855 in the 2023-2024 school year, but this has not translated into significantly improved academic outcomes, suggesting that the school may need to re-evaluate how it allocates its resources to better support student learning.
