Summary:
Zip code 21037 in Edgewater, Maryland, is home to a single large high school, South River High, which serves grades 9 through 12 and is part of the Anne Arundel County Public Schools district.
South River High is a standout school in the state, currently ranked 20th out of 227 high schools in Maryland (91st percentile, 5-star rating), a notable improvement from 24th the previous year. The school excels dramatically in English Language Arts, with an 86.8% proficiency rate that far exceeds both the district (55.9%) and state (51.7%) averages. It also boasts a strong 94.8% graduation rate, well above the district average of 88.9%. However, the school faces a significant challenge in mathematics, where only 22.2% of students are proficient—a figure below both the district (29.3%) and state (27.1%) averages. This persistent math weakness, also seen in the prior year's 20.2% proficiency rate, creates a striking 64.6 percentage point gap between ELA and math performance.
With an enrollment of 1,680 students and a student-teacher ratio of 17.1:1, the school spends $17,738 per student, which is relatively high given that only 20.18% of students qualify for free or reduced lunch—a rate below the state average. Chronic absenteeism stands at 19.0%, slightly better than the district average but still affecting nearly one in five students. The school's ability to achieve a top-10% state ranking despite below-average math scores suggests that its exceptional ELA performance and high graduation rate heavily influence its overall standing. For parents, South River High offers a strong academic environment in language arts and a supportive community, but the math proficiency gap is a key area to investigate further.
