Best Public Schools in Zip Code 03858

ZIP code 03858 has two public schools serving grades K–8: Memorial School, serving grades 3–5, and Seacoast Classical Academy Chartered Public School, serving grades K–8. Together, they enroll 418 students and offer families two different school structures: a smaller upper-elementary school connected to the Sanborn Regional School District and a K–8 charter public school operated by Seacoast Classical Academy Chartered Public School.

Memorial School is the clear overall academic standout. It ranks 49th out of 230 statewide schools, placing it in the 79th percentile, while Seacoast Classical Academy Chartered Public School ranks 143rd, in the 38th percentile. Memorial also reports higher 2025–2026 proficiency in mathematics, reading, and science: 70%, 61%, and 47%, compared with 38%, 54%, and 12% at Seacoast Classical. Memorial’s strongest results are in fourth- and fifth-grade mathematics, where proficiency reaches 80% and 75%. Its ranking and subject results have also improved steadily in recent years. The school reports a substantially lower student-teacher ratio—9.0 compared with 17.9 at Seacoast Classical—which may be an important consideration for families, although the available data do not establish a direct cause-and-effect relationship.

Seacoast Classical’s results are more uneven, but its later tested grades show encouraging strengths. Fifth-grade mathematics proficiency is 58%, and fifth-grade reading is 64%, both above the state averages; sixth-grade mathematics and reading are also slightly above state results. Reading is the school’s most competitive subject overall, at 54% compared with 55% statewide. Its largest concern is science, particularly fifth grade, where 17% of students are proficient versus 38% statewide. Families comparing these schools should also account for their different grade spans: Memorial serves only grades 3–5, while Seacoast Classical serves K–8, so schoolwide figures are not perfectly equivalent. Overall, Memorial offers more consistently strong academic performance, while Seacoast Classical may appeal to families seeking a longer K–8 pathway and should be evaluated especially closely for early-grade math and science performance.
