Mansfield High is a 4-star school and remains in roughly the top 28% of Massachusetts high schools. Its rank moved from 66th in 2023–2024 to 101st in 2024–2025 and 100th in 2025–2026; the percentile fell from 81 to 71, then edged up to 72. For 2024–2025, its graduation rate was 97.1% and dropout rate was 1.6%, both essentially matching the Mansfield district. The student-teacher ratio is 11:1. MCAS Next Generation results are above state in every reported subject. In 2025–2026, 10th-grade Mathematics was 60.70% proficient versus 43.73% statewide (+16.97 points), English Language Arts was 55.56% versus 45.48% (+10.08), Science was 45.18% versus 40.50% (+4.68), and Biology End of Course was 45.16% versus 37.68% (+7.48).

Year over year, Math improved from 57.08% to 60.70%, while ELA fell from 62.50% to 55.56% and Science fell from 50.67% to 45.18%. Biology is not directly comparable across years because one year is All Grades and the other is End of Course. Overall, Mansfield High is a strong choice: graduation is very high, dropout is low, and achievement is consistently above the state, especially in Math and ELA. The main cautions are recent ELA and Science declines, the rank dip from 2023–2024, and limited context because free/reduced-lunch data is blank and per-student spending is from 2020–2021.
