Summary:
The Millis area in Massachusetts has one public high school, Millis High School, serving grades 9–12 with 286 students. It is a small school with a 10.6:1 student-teacher ratio in 2024–2025, which may mean more individualized attention, though small cohorts can also make year-to-year test results swing more. The record does not include a free/reduced-lunch percentage, so socioeconomic context is not available, and per-student spending of $18,898 is from 2020–2021, much older than most other data.
Academic and outcome data show a mix of strengths and recent changes. The school’s 2024–2025 graduation rate was 98.7%, above the district’s 96.3%, and its dropout rate was 1.3%, compared with 1.2% for the district. In 2024–2025, 10th-grade MCAS proficiency was well above the state: ELA 77.63% vs. 50.66%, Mathematics 63.64% vs. 44.60%, and Science 68.42% vs. 45.89%. In 2025–2026, reported 10th-grade proficiency fell to 53.23% in ELA, 47.62% in Mathematics, and 39.29% in Science. ELA and Mathematics remained above both district and state, but Science was above the district and below the state (39.29% vs. 40.50%). Biology End-of-Course proficiency was 56.52%, far above the state’s 37.68% but slightly below the district’s 57.53%.
The school’s rank moved from the 85th percentile and 4 stars in 2023–2024, to 84th percentile and 4 stars in 2024–2025, then to 68th percentile and 3 stars in 2025–2026. That is still above the district’s 64th percentile, but the decline matches the lower 2025–2026 test scores, especially in Science. For parents, the main takeaway is that Millis High School has strong graduation, dropout, and student-teacher indicators and often outperforms the state in ELA and Mathematics, but recent academic results and ranking have softened. The key question is whether 2025–2026 is a one-year fluctuation or the start of a trend.
