Summary:
ZIP code 01940 is home to exactly one public high school: Lynnfield High, a grades 9–12 school with 588 students on Essex Street in Lynnfield, part of the Lynnfield district. Because it is the only high school in the ZIP, there is no in-area peer comparison to make; the meaningful benchmarks are the district and the state. The district itself ranks 39th of 351 Massachusetts districts — the 89th percentile, with 4 stars — so this school sits within an unusually strong district.
Outcomes are strong. The 2024–2025 graduation rate was 98.6% (district: 97.9%), and the dropout rate was 0.7%, matching the district. The student-teacher ratio is 11.9. On MCAS Next Generation tests, the school beat both its district and the state in every reported measure. In 2025–2026, 10th-grade math proficiency was 62.66% versus 43.73% statewide, ELA was 59.38% versus 45.48%, science was 45.16% versus 40.50%, and end-of-course biology was 51.16% versus 37.68%. The school's margins over its own district are positive but narrow, generally under 3 percentage points.
Two items are worth watching. First, 10th-grade ELA and science proficiency dropped sharply in the latest year — ELA from 78.23% to 59.38% and science from 66.91% to 45.16% — while math dipped only modestly, from 65.99% to 62.66%. Second, the school's state rank has slipped from 27th of 348 in 2023–2024 to 55th of 349, then 90th of 353 in 2025–2026, moving from the 92nd percentile with 5 stars to the 75th percentile with 4 stars. It remains a 4-star, top-quartile school. Note that the reported per-student spending of $18,215 is from 2020–2021, and free/reduced lunch data is not reported in this extract, so it should be treated as unknown rather than zero.
