Summary

Clopper Mill Elementary is a public elementary school located in Germantown, Maryland, serving grades PK-5 with a student population of 460. The school is part of the Montgomery County Public Schools district, which is ranked 8th out of 25 districts in Maryland and has a 4-star rating from SchoolDigger.

Despite the district's strong performance, Clopper Mill Elementary has consistently underperformed compared to the district and the state of Maryland in both mathematics and English language arts proficiency across all grade levels. For example, in the 2024-2025 school year, only 15.7% of Clopper Mill students were proficient or better in mathematics, compared to 35.7% for the district and 26.5% for the state. The school's performance in science for 5th grade is also significantly lower than the district and state, with only 10.2% of students proficient or better. Additionally, Clopper Mill Elementary has consistently high chronic absenteeism rates, ranging from 23.2% to 32.1% over the past few years, which is significantly higher than the state average.

Interestingly, the nearby schools, such as Dr. Ronald E. McNair Elementary, Spark M. Matsunaga Elementary, and Diamond Elementary, significantly outperform Clopper Mill Elementary in academic proficiency, with much higher percentages of students meeting or exceeding state standards in mathematics, English language arts, and science. These nearby schools also have lower chronic absenteeism rates, suggesting that factors beyond just funding, such as curriculum, instruction, and school leadership, may be contributing to Clopper Mill Elementary's underperformance.
