Summary:
Zip code 20851 in Rockville, Maryland, is home to two elementary schools—Twinbrook Elementary and Meadow Hall Elementary—both serving grades PK-5 within the Montgomery County Public Schools district, which is ranked 8th out of 25 districts in Maryland.
Meadow Hall Elementary stands out as the higher-performing school in this area, despite serving a student population with a higher percentage of economic disadvantage (66.09% free/reduced lunch) compared to Twinbrook Elementary (57.08%). Meadow Hall achieves better academic results across nearly all metrics for the 2025-2026 school year, including higher state ranking (44th percentile vs. 39th), higher math proficiency (29.8% vs. 25.2%), and higher ELA proficiency (39.8% vs. 39.0%). It also has a significantly lower chronic absenteeism rate (15.7% vs. 25.0%) and a lower student-teacher ratio (9.5 vs. 12.1), with higher per-student spending ($25,783 vs. $24,645). These factors suggest Meadow Hall may have particularly effective interventions that help mitigate challenges associated with poverty.
Both schools share a notable weakness in 5th-grade math, where proficiency drops dramatically from 4th grade—Twinbrook falls from 32.9% to 15.3%, and Meadow Hall from 31.7% to 20.5%—indicating a systemic challenge in upper elementary math within the zip code. While Meadow Hall shows a clear upward trend in performance, Twinbrook’s results are more volatile, such as a 10.5-point jump in ELA proficiency from 2024-2025 to 2025-2026. Both schools trail the district averages in all subjects, but Meadow Hall is closer to those benchmarks, particularly in math (7.1 points below district) and science (13.3 points below), compared to Twinbrook’s larger gaps (11.7 points below in math and 19 points below in science).
