Summary

Cohasset Middle School is a top-performing public school in the Cohasset district, serving 300 students in grades 6 through 8 with a low 10:1 student-teacher ratio and per-pupil spending of about $17,500. This school stands out for its elite academic performance, with 82.77% of students proficient in English Language Arts and 71.28% in Math—far exceeding state averages of 41.53% and 40.74%, respectively. It consistently earns a 5-star rating and ranks 25th out of 484 middle schools statewide, placing it in an elite trio with Hingham Middle School (rank 37) and Norwell Middle School (rank 60), while leaving schools like John W Rogers Middle in Rockland (39% ELA) far behind.

A key differentiator is Cohasset’s exceptional support for special education students, ranking in the 98th percentile—a massive outlier compared to Hingham (82nd percentile) and Norwell (79th percentile). The school also excels in civics, with 75.26% of 8th graders proficient, nearly double the state average and well above Hingham (56.75%) and Norwell (54.55%). However, science scores (53.47% proficient) are a relative weak spot, lower than the district average (60.66%) and outperformed by nearby Gates Middle School in Scituate (62.57% proficient). While Cohasset outperforms Scituate in ELA and Math, this creates an interesting dynamic where each school has distinct academic strengths.

Despite its overall excellence, Cohasset shows a performance gap with low socioeconomic status (SES) students, ranking in the 84th percentile for this subgroup—still good but the school’s lowest-performing area. This suggests an opportunity to better support economically disadvantaged students. With a small enrollment of 300, Cohasset maintains its elite status through focused resources and a low student-teacher ratio, offering a more intimate learning environment than Hanover Middle (13.2:1) or East Middle School in Braintree (13:1). For parents seeking a school with strong academics and standout special education support, Cohasset Middle School is a compelling choice.
