Concord High School

Summary:

Concord High School is a public high school serving grades 9-12 in Wilmington, Delaware, with a student population of 1,014. The school is part of the Brandywine School District, which is ranked 9th out of 32 districts in the state and has a 4-star rating.

Concord High School consistently ranks among the top 10-15 high schools in Delaware, with strong academic performance on standardized tests like the SAT and DeSSA, exceeding district and state averages. The school maintains high graduation rates of over 91% and low dropout rates below 1.4%. However, Concord High School faces challenges with chronic absenteeism, which has fluctuated between 16.9% and 32.5% in recent years. Compared to other high schools in the Brandywine district, such as Mount Pleasant High School and Brandywine High School, Concord outperforms its peers, but lags behind high-performing charter schools in the area, like Calloway (Cab) School of the Arts and Charter School of Wilmington.

Concord High School's performance on metrics related to low socioeconomic status students is mixed, ranking 16th out of 32 Delaware high schools in the 2023-2024 school year, but 3rd out of 29 schools in the 2022-2023 school year. The school also faces challenges in ensuring equitable outcomes for all student subgroups, with its Asian students performing lower than the state average. Addressing these areas, as well as the chronic absenteeism issue, will be crucial for Concord High School to continue improving and providing a robust educational experience for its diverse student population.

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.
