Summary

Mary E. Griswold School is a PK–5 elementary school in Kensington, CT, serving 513 students in the Berlin School District, and it stands out as the highest-ranked elementary school among its nearby peers.

Griswold consistently outperforms state averages in every tested subject and grade level. Its 5th graders are a particular bright spot, with 68.4% proficient in ELA, 60.8% in math, and 63.3% in science — all well above both district and state averages. The school also outperforms Emma Hart Willard School, its same-district school just two miles away, by significant margins in 5th-grade subjects. Perhaps most notably, chronic absenteeism sits at just 8.5%, far below the district rate of 14.7% and the state rate of 16.4%, and dramatically better than nearby New Britain schools, which range from 14% to over 26%. This strong attendance likely plays a major role in the school's academic success.

The school is also remarkably effective with historically underserved students. Low-income students ranked in the 89th percentile statewide in 2023–2024, and special education students ranked in the 88th percentile in 2020–2021. Griswold achieves these results efficiently, spending about $15,512 per student — less than Emma Hart Willard School ($17,465), John Paterson School ($18,967), and Gaffney Elementary School ($21,053) — while maintaining a higher student-teacher ratio of 13.1 to 1. One trend worth monitoring is a gradual ranking decline, from the 69th percentile in 2022–2023 to the 62nd percentile in 2025–2026, though the school remains a solid 3-star institution. Overall, Mary E. Griswold is a high-performing, efficient school that delivers strong results across a wide range of students.
