Summary:
Holbrook has one high school, Holbrook Middle High School, which serves grades 6–12 with 665 students and is part of the Holbrook district, ranked 224 of 351 districts statewide (36th percentile, 2 stars). Because it is a combined middle/high school, its "All Grades" MCAS results blend middle school grades with 10th grade, so parents should look closely at grade-level numbers.
The school's overall trajectory is clearly upward: it rose from 260 of 348 (25th percentile, 1 star) in 2023–24 to 214 of 353 (39th percentile, 2 stars) in 2025–26, a 46-place and 14-percentile-point gain. ELA is the strongest area, improving from 38.86% to 43.73% proficient at All Grades and moving from 2.67 points below state to 3.70 points above. Seventh grade ELA (47.93% vs 39.91% state) and 8th grade Civics (49.49% vs 39.77% state) are the standout results, though both are middle school grades. Graduation is a clear positive at 94.6%, above the district's 93.3%, with a dropout rate of 4.1% versus the district's 4.0%.
Math, science, and physics are the biggest concerns. Math All Grades is 33.64% versus 41.11% state, with every reported grade level below state by roughly 5.3 to 8.7 points. Science All Grades is 27.88% versus 40.98% state, and Physics End of Course is far below at 20.83% versus 46.58%, a 25.75-point gap. At the high-school level specifically, 10th grade ELA, Math, and Science all fall below state. Context metrics are limited: the student-teacher ratio is 14.3, spending was $14,557 per student in 2020–21, and free/reduced lunch data is not reported, so it should not be assumed to be 0%.
