Summary:
Zip code 19810 in Wilmington, Delaware, is served by a single high school, Concord High School, a mid-sized public school within the Brandywine School District that enrolls 994 students in grades 9-12.
Concord High School is a standout performer, consistently beating both district and state averages across nearly every subject. In the most recent testing year, 59.67% of students scored proficient in ELA and 29.28% in math, compared to state averages of 44.02% and 18.16%, respectively. The school’s most remarkable achievement is in SAT Essay writing, where 76.61% of students met proficiency—a staggering 33.6 points above the state average and a dramatic 35.55-point improvement from the prior year. This suggests an exceptionally strong writing program. The school also excels in social studies (37.10% vs. 24.91% statewide) and science (39.00% vs. 37.61% statewide). These gains helped Concord jump from 13th to 6th in Delaware’s high school rankings, placing it in the 85th percentile. With a 91.8% graduation rate and a dropout rate of just 0.7%—nearly five and a half times lower than the state’s 3.9%—the school clearly supports student success.
While math remains the school’s relative weak spot, it still outperforms the state by over 11 points. One area to watch is chronic absenteeism at 16.7%, which is slightly above the district’s 15.7% but below the state’s 17.1%. Interestingly, this does not appear to hinder academic outcomes, suggesting effective catch-up strategies for students who miss class. At $16,365 per student and a 14.8:1 student-teacher ratio, Concord delivers strong returns on investment. The absence of free/reduced lunch data makes it hard to gauge socioeconomic context, but the school’s consistent outperformance of its district—especially in writing and math—makes it a clear educational leader in the area and one of Delaware’s rising stars.
