Summary

Grundy Avenue School is an elementary school in Holbrook, New York, serving 460 students from kindergarten to 5th grade. 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.

Grundy Avenue School consistently underperforms compared to the district and state averages in academic proficiency, particularly in English Language Arts and Math. The school's rankings for certain student subgroups, such as female, male, Hispanic, and low socioeconomic status students, are in the bottom 25% of New York elementary schools, indicating significant achievement gaps. However, the school's special education students performed relatively well, ranking in the top 28% of New York elementary schools in the 2020-2021 school year. The school's high percentage of students receiving free or reduced-price lunch, which has increased from 18.66% in 2021-2022 to 27.39% in 2023-2024, suggests that socioeconomic factors may be playing a significant role in the academic performance of Grundy Avenue School.

When comparing Grundy Avenue School to other elementary schools in the Sachem Central School District, it generally underperforms. For example, Tamarac Elementary School and Merrimac School both outperform Grundy Avenue School in academic proficiency rates and overall state rankings. The school's relatively high spending per student and low student-teacher ratio indicate that resource allocation may not be the primary driver of the school's underperformance, suggesting the need for targeted interventions and support systems to address the achievement gaps and improve overall academic outcomes.
