Best Elementary Schools in Zip Code 20878

This analysis examines ten elementary schools in zip code 20878, which covers parts of Gaithersburg and North Potomac, Maryland, all part of the Montgomery County Public Schools district. The schools serve grades PK-5 and present a starkly diverse educational landscape, ranging from some of the highest-performing elementary schools in the state to schools significantly below district and state averages.

The top performers are Travilah Elementary, ranked 13th in Maryland with 81.1% math and 84.5% ELA proficiency, and Diamond Elementary, ranked 39th with 70.9% math and 76.4% ELA proficiency. Rachel Carson Elementary also excels, ranked 42nd with the highest ELA proficiency (77.6%) among top-tier schools. In contrast, Brown Station Elementary faces significant challenges, ranked 606th with the lowest test scores (20.7% math, 34.8% ELA) and the highest chronic absenteeism rate (27.8%). Fields Road Elementary also struggles, ranked 308th with a 29.8% chronic absenteeism rate. Stone Mill Elementary (ranked 72nd) has shown a slight downward trend, while Darnestown Elementary (ranked 144th) has improved its state rank.

Key metrics reveal a strong correlation between socioeconomic status and performance, with schools having lower free/reduced lunch rates (like Diamond at 12.39% and Travilah at 13.44%) consistently outperforming those with higher rates (like Brown Station at 57.52% and Fields Road at 50.99%). Notably, higher per-student spending does not guarantee success; the lowest-performing schools spend more per student than top performers. Chronic absenteeism is a powerful indicator of academic challenges, and smaller class sizes do not ensure better results, as top schools often have larger student-teacher ratios. The average math proficiency across these schools is 56.3%, and average ELA proficiency is 66.1%, both well above district and state averages.
