Best Public Schools in Zip Code 21108

The six public schools serving zip code 21108 in Millersville, Maryland, part of the Anne Arundel County Public Schools district, offer a diverse educational landscape spanning elementary through high school, including a specialized alternative school, and reveal stark contrasts in academic performance and socioeconomic factors within a small geographic area.

The standout academic star is Shipley's Choice Elementary, which consistently ranks in the top 6% of Maryland elementary schools with a 5-star rating, boasting math proficiency of 67.7% and ELA proficiency of 76.6%, alongside the lowest chronic absenteeism rate (6.4%) and economic disadvantage (5.52% free/reduced lunch). In comparison, Millersville Elementary is a strong performer with a 4-star rating and scores well above district averages, but it serves a more economically diverse population (20.73% free/reduced lunch). At the middle school level, Old Mill Middle North shows a positive trend, improving from the 37th to the 60th percentile over three years, while Old Mill Middle South ranks in the 48th percentile. Both middle schools have a notable "Algebra I anomaly," where advanced students achieve high proficiency (37.9% and 55.1%) despite low overall math scores.

The most challenged traditional school is Old Mill High, which ranks in the bottom half of Maryland high schools (2-star rating) with a critical math proficiency of just 4.3%—far below the district (29.3%) and state (27.1%) averages—and the highest chronic absenteeism (31.5%) among traditional schools. Ruth Parker Eason School serves a specialized population with a very high per-student spending ($55,064) and low student-teacher ratio (5.1), but its 53.4% chronic absenteeism reflects unique challenges. A key takeaway is that spending alone doesn't guarantee success: Millersville Elementary spends more per student ($19,174) than Shipley's Choice Elementary ($16,857) but is outperformed, highlighting that factors like poverty and attendance have a more powerful impact on test scores than per-pupil spending.
