Summary
Tyngsborough High School is a public school serving grades 9–12 in Tyngsborough, MA, a town in the greater Lowell area, with 405 students. In the latest available year, 2025–2026, it ranked 105th of 353 Massachusetts high schools — the 70th percentile — with 4 stars. That places it above the state median and well above its own district: the Tyngsborough district ranked 156th of 351, the 56th percentile, with 3 stars. Among nearby schools, Westford Academy (96th percentile, 5 stars), Groton Dunstable Regional (87th) and Chelmsford High (86th) rank higher, while Dracut Senior High (35th) and Lowell High (27th) rank lower.
Academically, the school's clearest strength is science. In 2025–2026, Science proficiency was 52.17% (state average 40.5%) and Biology End of Course was 58.97% (state average 37.68%). ELA and Mathematics, however, were 45.33% each — essentially at the state averages, after several years well above them. Completion outcomes are strong: a 98.0% graduation rate and 1.0% dropout rate in 2024–2025, close to Westford (99.2%) and Chelmsford (98.8%) and far ahead of Dracut (90.9%) and Lowell (83.1%). The student-teacher ratio is 12.8, favorable among comprehensive high schools, and 2020–2021 per-pupil spending was $15,962.
Results vary across student groups. Low-income students improved from the 39th percentile in 2023–2024 to the 62nd in 2025–2026, and female students reached the 76th percentile, while the special education subgroup fell to the 14th percentile, 1 star, in 2024–2025. Looking longer term, the school was at the 84th–88th percentile in the mid-2010s and has mostly sat in the 70s since 2022–2023 — a relative decline, though it remains a 4-star school with excellent completion outcomes and a science-heavy academic profile.
