Original Research by School Decision on Clopper Mill Elementary
Clopper Mill Elementary is a regular public school in Germantown that serves prekindergarten through fifth grade. It is part of Montgomery County Public Schools, one of the largest and most fiscally prominent districts in Maryland, with an operating budget that accounts for roughly half of the county's entire spending. The school sits within the Clopper's Mill Village, one of six planned residential villages that make up Germantown, a large, unincorporated community that was designed with a central downtown and surrounding neighborhoods, each with its own schools, shopping, and public facilities. Germantown is known for its ethnic diversity and has a major high-tech employment corridor along the highway that bisects it, but the built environment is largely suburban and car-oriented outside the town center.
The student body is diverse. The largest demographic group is Hispanic students, who make up about half the enrollment, followed by Black students at roughly a third. Asian, white, and multiracial students each contribute smaller shares. A substantial share of students qualify for free or reduced-price meals, indicating a high level of economic need. English learner and special education counts were not available in the data, so a full picture of those populations is not possible from this source alone.
On the 2024-25 Maryland state assessments, Clopper Mill's results sit below state averages. In English language arts, proficiency rates rise steadily by grade level, from about a third of third graders meeting the bar to just over a third of fourth graders and close to that same level among fifth graders. In math, the pattern is a downward slope: roughly a fifth of third graders are proficient, a smaller share of fourth graders, and about a tenth of fifth graders. In science, only about a tenth of fifth graders reach proficiency. These are low numbers, and a parent may want to ask the school about what academic supports are available and how the school is addressing these gaps, particularly with the district's recent adoption of a new elementary literacy curriculum that may influence instruction going forward.
Because Clopper Mill only serves elementary grades, there is no graduation rate to report. The comparison data that would place the school relative to other schools in Montgomery County was not available due to an insufficient cohort, so it is not possible to say how this school stacks up against its neighbors in the same district.
The school is located in a community that has seen modest ongoing growth. Housing values in the area sit above the national median, though they have declined slightly in the past year. Rents have edged up a small amount. The affordability picture reflects the broader Washington area market, with a typical home price well above the national figure and a household income needed to buy that home that is higher than the national median. This is a costly place to live, and the high share of students qualifying for meal assistance suggests that many families in the school's attendance zone are feeling that pressure.
Montgomery County Public Schools has been conducting a systemwide boundary analysis as part of long-term facilities planning, a process that could eventually affect which elementary school a student attends. For families looking at Clopper Mill, this is a factor worth tracking, particularly if they are planning to move into the area with the expectation of a long-term attachment to this specific school.
Overall, Clopper Mill Elementary is a diverse, high-needs school in an expensive and growing suburban community, with proficiency rates that are low across tested subjects. The district's new literacy curriculum may represent a shift in approach, but the current results indicate that the school is facing significant academic challenges. A parent considering this school would want to understand what intervention and enrichment programs are in place, how the school supports students who are below grade level, and what the trajectory of improvement looks like.
