Summary

Griswold Middle School serves 529 students in grades 5–8 in Griswold, Connecticut, a small town in New London County. The school currently ranks 144th out of 258 Connecticut middle schools (44th percentile), placing it solidly in the middle of the pack statewide. About 54% of students qualify for free or reduced lunch, reflecting a majority low-income student body. On a positive note, chronic absenteeism has dropped from 21.6% in 2022-2023 to 13.7% today—better than both the Griswold School District rate of 19.1% and the state rate of 16.4%.

Academically, Griswold shows a clear split. English language arts is a genuine strength in the upper grades: 7th grade ELA proficiency is 56.6% and 8th grade reaches 66%, both above state averages. Mathematics is the bigger challenge, with 5th grade math at 36.8% and 7th grade at 30.9%—well below state averages. The exception is 8th grade math, which has been at or above state proficiency in recent years. Compared to nearby schools, Griswold trails higher-performing schools like Brooklyn Middle and Lebanon Middle, particularly in math, where Lebanon's 7th grade proficiency is more than double Griswold's. However, Griswold outperforms higher-poverty schools like Kelly STEAM Magnet Middle School, Windham Middle School, and Teachers' Memorial Middle School.

A notable finding is the resource disparity. Griswold has the highest student-teacher ratio (14.0) and the lowest per-pupil spending ($14,085) among nearby middle schools, while schools like Dr. Helen Baldwin Middle School spend over $21,000 per student with smaller class sizes. Despite this, Griswold achieves better results than several higher-spending, higher-poverty schools, suggesting efficient use of limited resources. The school's steady attendance improvement is a genuine success story and may lay the groundwork for future academic gains. Overall, Griswold is a solid mid-tier school with strong upper-grade ELA and improving attendance, but math proficiency, subgroup support, and resource constraints remain the key areas to watch.
