Best High Schools in Zip Code 21001

Zip code 21001 in Aberdeen, Maryland, is home to two high schools within the Harford County Public Schools district: Aberdeen High, a traditional comprehensive school serving grades 9-12 with 1,396 students, and the Center for Educational Opportunity, an alternative school for grades 6-12 with just 122 students designed for those who have struggled in conventional settings.

Aberdeen High stands out as the higher-performing school in the area, with a stable 2-star rating and a strong graduation rate of 91.1%, nearly matching the district average of 91.9%. Its English Language Arts proficiency (50%) is close to the state average, though math proficiency is a significant concern at just 12.5%, well below the district (28.4%) and state (27.1%) averages. Interestingly, students who reach Algebra II at Aberdeen excel, with 63.5% proficient—far exceeding state and district rates. In contrast, the Center for Educational Opportunity faces extreme challenges, including a 42.3% graduation rate, a 51.2% dropout rate, and a staggering 72.5% chronic absenteeism rate. Despite spending nearly double per student ($32,127 vs. $16,192 at Aberdeen) to provide a low 6.5:1 student-teacher ratio, its math and ELA proficiency rates are just 2.0% and 37.4%, respectively.

The most striking takeaway is the stark contrast between these two schools, which serve fundamentally different missions within the same zip code. Aberdeen High is a typical public high school with manageable challenges, while the Center for Educational Opportunity is a high-cost intervention for at-risk students, where chronic absenteeism appears to be the root cause of low outcomes. For parents, this means that while Aberdeen offers a solid, traditional education path, the alternative school reflects the intensive resources needed to support students who have not succeeded elsewhere.
