Summary:
ZIP code 01862 contains two public schools, both K–4 elementary schools in the Billerica district: Hajjar Elementary with 401 students and Frederick J Dutile with 310 students, and there are no middle, high, or alternative schools in the ZIP. Both schools have MCAS results for 2024–2025 and 2025–2026, three years of rank history, per-student spending from 2020–2021, and student–teacher ratios from 2024–2025; free/reduced lunch data for 2024–2025 is blank, so it is unknown.
Frederick J Dutile is the standout school. In 2025–2026, its all-grade proficiency was 46.90% ELA and 45.13% math, above the Billerica district averages of 41.81% ELA and 41.69% math and above the state averages of 40.03% ELA and 41.11% math. Hajjar Elementary was below both, at 35.46% ELA and 34.51% math. Frederick J Dutile also had the ZIP’s highest grade-level result—3rd grade ELA at 63.16%—while Hajjar Elementary’s 3rd grade math, 27.85%, was the lowest, far below district and state. Still, Frederick J Dutile’s 4th grade results were weaker at 30.36% ELA and 41.07% math, and Hajjar Elementary slightly edged it in 4th grade ELA and math.
Both schools have trended downward. Frederick J Dutile fell from the 71st percentile with 4 stars in 2023–2024 to the 57th percentile with 3 stars in 2025–2026, while Hajjar Elementary fell from the 58th percentile with 3 stars to the 36th percentile with 2 stars. Both also declined from 2024–2025 to 2025–2026, with math drops larger than ELA drops. Hajjar Elementary spends more per student ($18,669 vs. $18,281) and has a slightly lower student–teacher ratio (13.9 vs. 14.2), but that does not line up with higher outcomes. Overall, Frederick J Dutile remains the stronger school academically, while Hajjar Elementary is larger but currently weaker; both need improvement, especially in math.
