Summary

Derby High School is a public high school serving 369 students in grades 9-12 in Derby, Connecticut, a diverse community located in the southern part of the state. While the school has a relatively low student-teacher ratio and high per-student spending, it has consistently ranked in the bottom half of Connecticut high schools and struggles with academic performance that is significantly below the state average.

Derby High School's academic challenges are evident in several key metrics. Only 7.1% of 11th-grade students were proficient or better in SAT/Math in the 2022-2023 school year, compared to the state average of 34.1%. The school's overall ranking has dropped from 106 out of 132 Connecticut high schools in 2015-2016 to 120 out of 142 in 2022-2023. These academic struggles are particularly pronounced among the school's diverse student population, with significant racial disparities in performance between white/Asian and African American/Hispanic students.

When compared to nearby high schools such as Trumbull High School, Woodland Regional High School, and Amity Regional High School, Derby High School's academic performance and overall school quality are significantly lower. These neighboring schools have higher standardized test scores, higher rankings, and lower percentages of students from low-socioeconomic backgrounds, suggesting that factors beyond just funding may be contributing to Derby High School's challenges.
