Summary:
This analysis examines four elementary schools in the 20815 zip code (Chevy Chase, MD), all part of the highly-rated Montgomery County Public Schools district, serving grades PK-5 in an affluent suburban area near Washington, D.C.
Chevy Chase Elementary is the standout performer, ranking in the top 5% of Maryland schools (47th out of 864) with the highest proficiency rates in Math (67.6%) and English Language Arts (75.0%). It also boasts the lowest chronic absenteeism rate (8.6%) and exceptional 5th-grade Science scores (72.7%), nearly double the district average. Somerset Elementary is another top-tier school, ranking 78th in the state with strong ELA scores and the lowest free/reduced lunch rate (20.06%). North Chevy Chase Elementary, the smallest school (237 students), has the highest per-student spending ($22,568) but the lowest state ranking (93rd) and test scores among the group. Rock Creek Forest Elementary shows a promising upward trend in its state ranking (now 145th) and has the lowest student-teacher ratio (13.7:1) and highest enrollment (690 students).
A key finding is the spending vs. performance paradox: North Chevy Chase spends the most per student but achieves the lowest results, while Chevy Chase spends the least ($17,141) yet achieves the highest. This suggests factors like teaching quality and community involvement are powerful drivers. Additionally, Chevy Chase's success is notable as it achieves top results despite having the highest economic disadvantage rate (34.79%) and the largest class sizes (18.3:1), proving that socioeconomic factors are not deterministic. Chronic absenteeism strongly correlates with performance, as Chevy Chase's low rate (8.6%) aligns with its top ranking, while Somerset's higher rate (20.6%) corresponds with slightly lower scores. All four schools significantly outperform district and state averages in Math and ELA.
