Summary

Knollwood Elementary School is a public elementary school serving grades K-3 in Piscataway, New Jersey, with 467 students. It is part of the Piscataway Township School District, which is ranked 302 out of 609 districts in the state and has a 3-star rating from SchoolDigger. Knollwood Elementary School has received a 4-star rating, indicating it is performing above average compared to other elementary schools in New Jersey.

Knollwood Elementary School consistently outperforms the Piscataway Township School District and the state of New Jersey in standardized test scores for 3rd grade students. In the 2024-2025 school year, 60.7% of Knollwood's 3rd graders were proficient or better in English Language Arts, compared to 46.8% for the district and 44.9% for the state. In math, 62.6% of Knollwood's 3rd graders were proficient or better, compared to 54.6% for the district and 49.8% for the state. The school also stands out in its performance for certain student subgroups, ranking highly for African American students, English Language Learners, and students of low socioeconomic status.

However, Knollwood Elementary School has seen a steady increase in chronic absenteeism, from 7.7% in 2021-2022 to 14.9% in 2023-2024, which is an area of concern. The school outperforms nearby Randolphville Elementary School and Grandview Elementary School in both English Language Arts and Mathematics proficiency, but lags behind the higher-performing Martin Luther King Elementary School, which serves grades 4-5 in the same district. Knollwood's relatively low spending per student and student-teacher ratio suggest it may be operating efficiently, which could be a model for other schools in the district.
