Summary:
ZIP code 03301 has two public high schools serving grades 9–12: Concord High School and Synergy Academy Chartered Public School. Together, they enroll 1,415 students, but Concord serves about 98.5% of them with 1,394 students, while Synergy enrolls just 21. The schools offer very different settings: Concord is a large traditional high school, while Synergy is a very small chartered public school likely to provide a more individualized environment.
Concord has the most complete record of academic information and shows a mixed but improving profile. Its state ranking rose from the 31st percentile in 2023–2024 to the 51st percentile in 2025–2026, and its rating increased from two stars to three. Reading and science are relative strengths: 58% of students were proficient in reading and 42% in science, both slightly above state results. Mathematics is the main concern, with only 19% proficient compared with 44% statewide and 41% in the Concord School District. The math result also declined from the prior year. Concord’s 73.2% graduation rate is below the 87% state rate, although its 1.0% dropout rate is better than the 2.3% statewide rate.
Synergy stands out for its student-teacher ratio of 9.5, compared with 13.0 at Concord, but the available information does not include testing, graduation, dropout, or ranking results. Its very small enrollment means that any future percentages could change substantially based on only a few students, so direct academic comparisons are not currently possible. For families choosing between the schools, Concord offers the scale and broader course opportunities of a large high school, along with more evidence about outcomes; Synergy may appeal to families seeking a smaller setting and lower student-teacher ratio. The most important questions for Concord concern mathematics support and helping more students graduate, while Synergy would benefit from additional publicly available achievement and completion data.
