Summary

In Iselin, New Jersey, Robert Mascenik Elementary School serves 288 students in kindergarten through grade 5 in the Woodbridge Township School District. Its clearest concern is mathematics: the three-grade average fell from 66% in 2022–2023 to 45% in 2025–2026, moving from 23 points above the state to 2 points below it.

English Language Arts is a current strength compared with nearby schools, the district, and the state: Mascenik averaged 58% proficient in 2025–2026, versus 54% at nearby schools, 46% in the district, and 49% statewide. Math is more mixed: the 45% average was above the district’s 42%, but below nearby schools’ 49% and the state’s 47%. Results also differ by grade: fourth-grade math was 49%, above nearby schools’ 47%, while third-grade math was 45%, below the nearby average of 52%. Fifth-grade science has declined, but its latest 31% result remained above the state’s 27% and district’s 26%, and was slightly above nearby schools’ 31%.

ELA has rebounded in recent years, rising from a 46% average in 2023–2024 to 58% in 2025–2026, while its result was 58% in both the first and latest years shown. SchoolDigger places Mascenik at the 55th percentile statewide, with 3 stars, down from the 75th percentile in 2022–2023; the district is at the 36th percentile with 2 stars.

Free/reduced lunch eligible students made up 27% of enrollment in 2024–2025, below the nearby-school average of 37%. SchoolDigger’s statewide ranking suggests lower measured effectiveness for Asian students (16th percentile) and Special Education Students (11th percentile) than for the school overall; the special education figure is available for only one year.
