Summary:
Zip code 06878 in Riverside, CT is home to one middle school, Eastern Middle School, serving grades 6–8 as part of the highly ranked Greenwich School District. This single school is an exceptional standout, holding a 5-star rating and ranking #2 in Connecticut for three consecutive years (99th percentile statewide). It is the only middle school in the zip code, so all comparisons are made against its district and the state rather than nearby schools.
Academically, Eastern Middle School outperforms both the district and state by wide margins. In the most recent year, English Language Arts proficiency ranged from 84.0% (8th grade) to 87.2% (6th grade), while math proficiency ranged from 83.6% (6th grade) to 86.6% (8th grade) — with 8th grade math being the strongest subject. Science proficiency in 8th grade reached 88.7%, compared to just 50.9% statewide. These figures are remarkably stable year over year. The school also has a very low chronic absenteeism rate of 6.4%, far below the district's 8.5% and the state's 16.4%. With a student-teacher ratio of 11.8 and per-student spending around $19,444, the school offers a resource-rich environment that supports individualized attention.
One interesting pattern is that while ELA proficiency declines slightly as students advance (from 87.2% in 6th grade to 84.0% in 8th grade), math proficiency rises by grade (from 83.6% to 86.6%) — the opposite of typical state and district trends. The school's average math proficiency is more than 40 percentage points above the state average, and its ELA average is nearly 35 points higher. Only 5.9% of students receive free or reduced-price lunch, indicating a largely affluent population. For parents, Eastern Middle School offers consistent, top-tier academics, strong attendance, and ample resources, making it one of the most successful public middle schools in Connecticut.
