Derby High School

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.

As you review the school rankings data, please be aware that some of the information from certain demographics is missing. The reason for this omission is that the data has been redacted from the source data itself due to low population samples in these specific demographic groups.

Redacting data from low population samples is a necessary step to ensure the reliability and accuracy of the results, as small sample sizes may not be representative of the broader population. Additionally, this measure helps protect the privacy of individuals belonging to these demographic groups.

About Students eligible for discounted/free lunch:

The National School Lunch Program (NSLP) provides low-cost or free meals to students in U.S. public and nonprofit private schools based on household income. Those with incomes below 130% of the poverty line receive free lunch, while those between 130% and 185% qualify for reduced-price lunch. The percentage of students receiving free or reduced-price lunch serves as a marker for poverty, as it reflects the socioeconomic status of families in a given school or district. A higher FRPL rate typically indicates a higher concentration of low-income families, suggesting that the school or district may face additional challenges in providing adequate resources and support for student success.

About Student-Teacher Ratio

Student/teacher ratio is calculated by dividing the total number of students by the total number of full-time equivalent teachers. Please note that a smaller student/teacher ratio does not necessarily translate to smaller class size. In some instances, schools hire teachers part time, and some teachers are hired for specialized instruction with very small class sizes. These and other factors contribute to the student/teacher ratio. Note: For private schools, Student/teacher ratio may not include Pre-Kindergarten.
