While the district as a whole performs well, with Stonington School District ranked 36 out of 156 districts in Connecticut, there are some areas for improvement. Chronic absenteeism rates are high across all schools, and there is variation in the percentage of free and reduced-price lunch recipients, suggesting potential socioeconomic disparities within the district. The district may benefit from further analysis and targeted interventions to address these challenges and ensure equitable access to resources for all students.
