Summary:

The Derby School District in Connecticut is home to three elementary schools: Irving School, Bradley School, and Little Raiders University. These schools serve students from kindergarten through fifth grade and provide educational opportunities in the Derby area.

Among the three schools, Bradley School stands out as the highest-performing, with a 3-star statewide ranking for the 2024-2025 school year, compared to Irving School's 0-star rating. Bradley School consistently outperforms the district and state averages in English Language Arts and Mathematics proficiency rates across multiple grade levels.

In contrast, Irving School lags behind the district and state averages in all tested subjects and grade levels. This disparity in academic performance may be related to the school's higher percentage of free and reduced-price lunch recipients, which could indicate a higher concentration of economically disadvantaged students. Additionally, the per-student spending and student-teacher ratios suggest that the district may not be allocating resources evenly across the schools, which could contribute to the performance gap.
