Summary
Lilja Elementary is a K–4 school in Natick, MA, serving 445 students as part of Natick Public Schools, a district ranked 45th of 351 in Massachusetts (87th percentile, 4 stars). Lilja itself ranked 364th of 899 in 2025–2026 (60th percentile, 3 stars), down from 4-star, low-80th-percentile standings in 2021–2022 and 2022–2023. In 2025–2026 MCAS, all-grade proficiency was 42.78% in English Language Arts and 50.56% in Mathematics—above Massachusetts averages of 40.03% ELA and 41.11% math, but below Natick’s district averages of 60.05% ELA and 67.14% math. Because it serves grades K–4, it has no grade-5 science results.
Within Natick, Lilja is the lowest-ranked of the four elementary schools shown. Brown (88th percentile, 4 stars), Memorial (92nd, 5 stars), and Bennett-Hemenway (88th, 4 stars) all rank higher. Lilja’s ELA is about 17–24 points lower and math about 18–19 points lower. Lilja has the lowest student-teacher ratio among these Natick schools (11.7), and its per-student spending ($15,584 in 2020–21) is close to that of Brown and Bennett-Hemenway and above Memorial’s, so class size and within-district spending do not clearly explain the gap. Compared with nearby out-of-district schools, Lilja also trails Happy Hollow School (Wayland), Pine Hill (Sherborn), Loker School (Wayland), Katharine Lee Bates (Wellesley), Sprague Elementary School (Wellesley), Hunnewell (Wellesley), and John D Hardy (Wellesley), which rank 92nd–100th percentile. Those schools spend roughly $18,271–$24,057 per student, while Lilja’s 11.7 ratio is similar to some of them.
The decline is notable. In 2022–2023, Lilja’s ELA was 59.33% and math 61.84%, only 5.58 and 3.83 points below the Natick district. By 2025–2026, gaps widened to 17.27 points in ELA and 16.58 in math. Subgroup effectiveness—how well the school serves specific populations—shows the clearest concern: low-SES students rank 25th percentile (1 star) in 2025–2026 and 10th percentile (1 star) in 2024–2025; Hispanic students rank 35th percentile; White students 49th; Asian students dropped from 90th percentile in 2022–2023 to 48th in 2025–2026; Special Education students are stable at 56th–61st. Data limitations matter: free/reduced-lunch data are unavailable, spending is from 2020–21, and some subgroups have only one or two recent years.
