High Schools in Lincoln-Sudbury

The Lincoln-Sudbury area is served by a single public high school, Lincoln-Sudbury Regional High, which educates 1,445 students in grades 9–12 at 390 Lincoln Rd in Sudbury as part of the Lincoln-Sudbury district. Because it is the only high school listed, there are no cross-school comparisons; instead, the school can be measured against the state and its own prior years. The district ranks 26th of 351 in Massachusetts (93rd percentile, five stars), and the school ranks 34th of 353 high schools for 2025–2026 (90th percentile, five stars). Its rank history — 18th of 348 in 2023–2024, 42nd of 349 in 2024–2025, and 34th of 353 in 2025–2026 — puts it consistently in the top 10% statewide, with some year-to-year movement.

On MCAS Next Generation tests, the school beats the state average in every reported subject and year. In 2025–2026, 66.77% of 10th graders were proficient in English Language Arts versus 45.48% statewide (a 21.29-point gap), 81.29% in Mathematics versus 43.73% (a 37.56-point gap), and 69.4% in Science versus 40.5% (a 28.90-point gap). Biology End of Course was 69.42% proficient against 37.68% statewide. Mathematics is the clearest strength and improved from 78.14% the prior year. The main watch item is ELA, which fell 8.75 points from 75.52%; the state declined too, but less steeply, narrowing the school's advantage from 24.86 to 21.29 points. Science slipped only 0.75 points, and its gap over the state actually widened.

Outcomes beyond testing are strong: the school posted a 98.7% graduation rate and a 0.0% dropout rate in 2024–2025, versus district figures of 98.0% and 0.5%. The student-teacher ratio is a favorable 11.3 students per teacher, though no state average is given for comparison. Per-student spending of $20,935 is reported only for 2020–2021 and should not be read as a current figure. Free/reduced-lunch data for 2024–2025 is not reported (not zero), limiting analysis of socioeconomic composition. Overall, this is a top-decile Massachusetts high school whose standout strengths are Mathematics, Science, and Biology, with ELA the single academic item to watch.
