Summary

Diamond Elementary in Gaithersburg, MD, is a high-performing school within the Montgomery County Public Schools district, serving 654 students from Pre-K through 5th grade in a community where only about 12% of students qualify for free and reduced lunch.

Diamond Elementary consistently ranks among the top 6% of all elementary schools in Maryland, achieving a 95th percentile ranking in the 2025-2026 school year. Its academic performance far exceeds district and state averages: 70.9% of students are proficient in math (compared to 36.9% district-wide), 76.4% are proficient in English Language Arts (compared to 58.5% district-wide), and 63.9% of 5th graders are proficient in science (compared to 40.1% district-wide). This places Diamond as a clear academic leader alongside nearby Rachel Carson Elementary, which ranks 42nd in the state. Interestingly, Diamond achieves these results with lower per-student spending ($19,076) than several lower-performing nearby schools, such as Fields Road Elementary ($23,354) and Clopper Mill Elementary ($24,605). The school also boasts the lowest chronic absenteeism rate among nearby schools at 12.8%, nearly half the district average of 22.6%, and has shown a strong recovery from pandemic-era disruptions.

A standout achievement is Diamond Elementary’s ranking as 1st out of 115 schools statewide for its effectiveness in serving English Language Learner students, demonstrating highly successful support programs. The school’s academic strength is consistent across all grade levels, with 5th grade showing the strongest performance in both math and ELA. This contrasts sharply with Brown Station Elementary, located just 0.49 miles away, which ranks in the 30th percentile and serves a student population with a much higher percentage of students eligible for free and reduced lunch (57.52%). This stark difference highlights how school performance can vary significantly within the same district and geographic area.
