Summary:
Schools in Concord-Carlisle comprise a single high school — Concord Carlisle High — serving grades 9–12 in Concord, Massachusetts, with 1,191 students and no elementary, middle, or alternative schools included in this extract. Because only one school is listed, there is no sibling school to compare against within the Concord-Carlisle district; the comparisons below are to state averages and to the school's own prior years.
The school is a top performer statewide. Its district ranks 14th of 351 in Massachusetts, in the 96th percentile with a 5-star rating, and rank history places the high school in the top 5% every year: 15th of 348 in 2023–2024, 14th of 349 in 2024–2025, and 18th of 353 in 2025–2026, each with 5 stars. MCAS Next Generation proficiency runs far ahead of the state in every listed subject. In 2025–2026, 10th-grade ELA was 73.14 versus 45.48 statewide (+27.66 points), Mathematics 80.78 versus 43.73 (+37.05), Science 76.87 versus 40.50 (+36.37), and Biology End of Course 78.33 versus 37.68 (+40.65). For all listed results, school and district values are identical, so district test performance here effectively reflects this one high school.
Trends are mostly strong, with one watch item. Tenth-grade ELA dropped from 83.83 in 2024–2025 to 73.14 in 2025–2026, a 10.69-point decline, though it remains more than 27 points above the state, and the school's relative ELA edge narrowed from +33.17 to +27.66. Mathematics was essentially flat (80.61 to 80.78), while Science fell from 79.60 to 76.87 but widened its relative advantage because the state fell more. Note that 2025–2026 Biology is End of Course and 2024–2025 Biology is All Grades, so those two are not directly comparable. Graduation is 97.7% (district 96.8%) with a 0.3% dropout rate, the student-teacher ratio is 11.4:1, and per-student spending was $21,412 in 2020–2021; free/reduced lunch data is not available, so demographic context is limited.
