The school enrolls 277 students and is the only local middle-school option for families living in the ZIP code.

Seabrook Middle School has its strongest academic results in reading.

Eighth-grade reading was a particular bright spot, with 54% proficiency—three points above the state average. Mathematics proficiency was 34%, nearly matching the district’s 35% but trailing the state’s 44%. Fifth-grade math was relatively strong at 42%, while results fell to 33% in sixth grade, 34% in seventh grade, and 29% in eighth grade. This drop after fifth grade makes the transition into middle-school mathematics an important area for families to monitor.
Science is the school’s weakest subject overall, with 28% of students proficient, equal to the district but 10 points below the state. Fifth-grade science was especially low at 23%, while eighth-grade science rose to 32%. The school ranked 94th out of 138 schools in 2025–2026, around the 32nd percentile, and received two stars; the district ranked 146th out of 166 districts with one star. Rankings have fluctuated rather than followed a steady trend. Overall, the school performs better relative to its district in reading than in other subjects, while mathematics and science require the most improvement. Families may want to ask about math support during grades 6–8, science instruction, and how the school uses its favorable staffing ratio to provide intervention and enrichment.
