Middlesex Middle School

Middlesex Middle School, located in Darien, CT, serves 1,043 students in grades 6 through 8 and is part of the highly rated Darien School District. Consistently ranked among the very best in the state, Middlesex Middle School currently holds the #6 spot out of 258 Connecticut middle schools, landing in the 98th percentile. It has never ranked lower than 6th in the past decade and earns 5 stars in virtually every annual ranking. Students here post proficiency rates roughly 30 to 40 percentage points above the state average in ELA, math, and science across all grade levels.

Middlesex operates in a fiercely competitive region. While Saxe Middle School in New Canaan (#1) and Eastern Middle School in Greenwich (#2) edge it out in a few metrics like 8th grade math and science, Middlesex dramatically outperforms schools just a few miles away in Stamford and Norwalk. For instance, Rippowam Middle School has 6th grade math proficiency around 12%, compared to Middlesex's 80.1%. The student body is also exceptionally advantaged, with a free/reduced lunch rate of just 1.63%, starkly contrasting with neighboring districts where rates often exceed 50%.

Beyond its elite rankings, Middlesex shows remarkable consistency and strength across all student subgroups, including top rankings for special education students and strong outcomes for Hispanic students. The school has also shown steady improvement in 8th grade science, rising from 76.3% proficiency in 2022 to 85% today. One trend to watch is chronic absenteeism, which has risen from 5.8% to 8.4% over the past few years—still well below the state average of 16.4% but higher than its immediate high-performing peers. Interestingly, high spending alone doesn't explain Middlesex's success, as Central Middle School in Greenwich spends significantly more per student yet posts lower scores. In short, Middlesex provides a reliably excellent, well-resourced education, surrounded by both extraordinary peers and schools facing far greater challenges.
