For parents exploring this area, the district is strong overall, but schools vary notably. Hebron Avenue School is the district’s standout, ranking 25th among 491 elementary schools (95th percentile) with an 82% average proficiency rate, the lowest chronic absenteeism (4.6%), and the lowest poverty rate (7.0%). Nayaug Elementary School is the equity success story, achieving 78.6% proficiency despite higher poverty (17.3%) and absenteeism (8.9%), while steadily improving its state rank from 70th to 48th. Smith Middle School has been remarkably consistent, ranking in the top 25 middle schools for three straight years with all subject scores between 72-74%. Glastonbury High School posts a 97.2% graduation rate and 83.5% science proficiency, crushing state averages. On the other end, Naubuc School ranks 171st (65th percentile) with the lowest proficiency (65.1%) and by far the highest poverty rate (30.6%), while Buttonball Lane School has declined from 65th to 107th over three years.
Across the district, every school beats Connecticut state averages, yet the gap between Hebron and Naubuc is nearly 17 points in proficiency. Poverty correlates with performance but not perfectly – Nayaug excels despite economic challenges. Spending varies dramatically by school level, with the high school spending $24,386 per student versus about $11,600-$12,100 at elementary schools, though student-teacher ratios are consistently between 12.6 and 13.7. Chronic absenteeism is low district-wide (6.4%) but runs in two tiers, and the high school’s science proficiency jumped 19.3 points in one year. Overall, this is a strong district with clear opportunities for peer learning, especially for Naubuc and Buttonball.
