Schools in Zip Code 03603

ZIP code 03603 is a small school area with two public schools serving prekindergarten through eighth grade: Charlestown Primary School and Charlestown Middle School, both part of the Fall Mountain Regional School District. Together, they enroll 402 students, and there is no high school listed within the ZIP code.

Charlestown Primary School serves 234 students in grades PK–4 and has a 9.7-to-1 student–teacher ratio. Its strongest area is mathematics: 43% of students were proficient in 2025–26, eight points above the district and just one point below the state. Reading is a more significant concern, with 32% proficiency compared with 49% in the district and 55% statewide. Fourth-grade reading was particularly low at 29%, while fourth-grade math also fell below third-grade performance. The school’s latest ranking declined sharply, so parents may want to ask about reading interventions, fourth-grade support, and recent instructional changes.

Charlestown Middle School serves 168 students in grades 5–8 and has an even lower 9.3-to-1 student–teacher ratio. Compared with Primary, Middle has stronger overall reading results, at 43%, but substantially weaker mathematics results, at 25%. Fifth-grade math was the biggest concern, with only 14% proficiency, although the school’s overall math result improved five points from the prior year. Sixth-grade reading was relatively strong at 51%, aligning closely with district and state results, but reading declined to 33% by eighth grade. Science was mixed: fifth grade exceeded district and state performance, while eighth grade was much weaker. Middle’s ranking percentile improved over three years, but both schools remain below statewide averages in most subjects. Key priorities are middle-school math, later-grade reading, and the large fifth-to-eighth-grade science gap.
