Summary:
Zip code 01742 covers Concord, Massachusetts, and contains five public schools serving 3,105 students across two districts: the PK–8 Concord district and the 9–12 Concord-Carlisle district. Those schools are Concord Carlisle High (grades 9–12, 1,191 students), Concord Middle (6–8, 643), and three PK–5 elementaries — Alcott (438), Willard (432), and Thoreau (401). Elementary enrollment (1,271) is the largest segment, followed by high school (1,191) and middle school (643). Both districts rate highly: Concord-Carlisle ranks 14th of 351 and Concord 28th of 351, each at five stars.
Every school here clears the state proficiency bar by 20 to 37 points. Concord Carlisle High posted 10th-grade proficiency of 80.78% in math, 78.33% in biology, 76.87% in science, and 73.14% in ELA, with a 97.7% graduation rate and a 0.3% dropout rate. Concord Middle ranked 10th of 484 in 2024–25 (98th percentile) and beats its own district in every subject tested. Willard is the strongest elementary — 79th of 899, five stars in all three years, and the highest elementary science score (72.46). Thoreau holds the top individual grade results (3rd-grade ELA 85.11, 4th-grade math 79.69). Alcott ranks lowest of the five (157th of 899, 83rd percentile, four stars) and is the only school below district average in all six all-grade subjects and the only one to decline in every all-grade subject.
Across all three elementaries, 5th grade is the weakest link: ELA of 46.48 at Alcott, 52.86 at Willard, and 56.16 at Thoreau, against a district average of 51.38. Same-district gaps are wide — 5th-grade math was 72.86 at Willard versus 52.11 at Alcott, a 20.75-point spread. Thoreau's all-grade science fell 19.1 points, the largest single-subject swing in the data set. Declines were mostly in ELA and science; math rose slightly in the elementary grades and at the middle school. Per-student spending is tightly clustered, spanning just $1,219 (5.7%), with student-teacher ratios from 9.6 to 11.6. Free/reduced-lunch percentages are blank for all five schools, so no economic-mix or equity analysis is possible.
