Summary

Dedham High is a public high school in Dedham, Massachusetts, serving grades 9–12 with 719 students. It's part of the Dedham district, and it sits in a peer group that ranges from high-performing suburbs to a set of Boston-area schools, which makes it a useful reference point for families comparing nearby towns.

Statewide, Dedham High ranks 134th of 353 high schools in 2025–2026 — the 62nd percentile, with a 3-star rating. That's up from 156th last year but below its 111th-place finish in 2023–2024 and well below its mid-2010s peak, when it ranked in the 90s with 4 stars. Compared with neighbors, the school clearly outranks Norwood High (43rd percentile) and every Boston-area school in this comparison, including New Mission High School, Boston Preparatory Charter Public School, Academy Of the Pacific Rim Charter Public School, Margarita Muniz Academy, Another Course To College, and Boston International High School & Newcomers Academy. It trails the top suburban districts by a wide margin, however: Needham High (97th percentile), Westwood High (92nd), and Milton High (89th).

Academically, math is Dedham's standout: 57.58% of 10th graders were proficient in 2025–2026, well above the state's 43.73% and far ahead of Norwood's 40.52. English language arts sits at 45.8%, essentially at the state average, and science at 41.13% is slightly above it. The gap to Needham, Westwood, and Milton is largest in ELA. The dropout rate is a concern: it rose to 5.1% in 2024–2025 from 1.8% the year before, and the 91.9% graduation rate is below most nearby suburban schools. Results also vary by group — students from low-income families rank in the 32nd percentile and special education students in the 43rd. Notably, Dedham spends more per student ($22,292) and has a smaller student–teacher ratio (10.3) than several higher-performing neighbors.
