Summary

Robert Mascenik Elementary School is a public elementary school located in Iselin, New Jersey, serving 306 students in grades K-5. The school is part of the Woodbridge Township School District, which is ranked 400 out of 609 districts in the state.

Robert Mascenik Elementary School stands out for its strong academic performance, consistently outperforming the district and state averages in standardized test scores across various grade levels and subjects. For example, in the 2024-2025 school year, the school's 3rd grade proficiency rates in English Language Arts (46.3%) and Mathematics (61.8%) were higher than the district (41.7% and 48.8%) and state (44.9% and 49.8%) averages. The school's 5th grade proficiency rates in Science (40%) were also significantly higher than the district (29.6%) and state (30.1%) averages. Additionally, the school has shown strong performance for certain student subgroups, such as English Language Learners and Low Socioeconomic Status students, ranking among the top elementary schools in New Jersey for these groups.

However, the school faces some challenges, including a gradual increase in chronic absenteeism rates, from 5.6% in 2020-2021 to 16.6% in 2022-2023. When compared to other elementary schools within the Woodbridge Township School District, Mawbey Street Elementary School and Avenel Street Elementary School have lower 3rd grade proficiency rates in English Language Arts and Mathematics. The school's relatively low per-student spending and higher student-teacher ratio compared to some nearby schools may also impact its ability to provide additional support and personalized attention to students, which could be a contributing factor to the observed academic performance gaps for certain subgroups.
