Mount Greylock

Mount Greylock is a Massachusetts district with three schools — two elementary schools serving PK–6 and one high school serving grades 7–12, meaning the middle grades are housed within the high school — enrolling 1,177 students in total.

The district ranks 81 of 351 statewide (77th percentile) with 4 stars, and its all-grade proficiency beats the state in ELA, math, and science. The subject lead is split: Williamstown Elementary is strongest in all-grade ELA (60.63%), Lanesborough Elementary is strongest in all-grade math (61.34%), and Mt Greylock Regional High is strongest in all-grade science (59.22%). Mt Greylock Regional High is a 4-star school in the 80th percentile with a 95.8% graduation rate and 4.2% dropout rate, plus large year-over-year gains in math (+14.56 points) and science (+12.86). Williamstown Elementary is also 4 stars (75th percentile) with steady rankings and an especially strong 3rd grade (math 79.25%, ELA 75.47%). Lanesborough Elementary is currently the only 3-star school (63rd percentile), down from 4 stars and the 70th percentile the prior year; its 6th-grade math (81.25%) is the highest single grade-level score here, but its all-grade science (31.03%) and 5th-grade ELA (24.14%) lag well behind.

Two patterns are worth watching. Fifth grade is a district weak spot, with district 5th-grade math at 37.04% and science at 41.46%, both below state averages. Elementary science also fell sharply — Williamstown from 61.54% to 48.08% and Lanesborough from 52.94% to 31.03% — while the district's science score stayed nearly flat only because the high school gained. Note that high school and elementary ranks are measured against different school groups, so percentiles and stars are better for comparison. Per-student spending (Lanesborough $22,250, Williamstown $21,340, Mt Greylock Regional High $20,369) is from 2020–2021 and free/reduced-lunch data is unavailable, so spending should not be read as a simple cause of outcomes.
