Original Research by School Decision on Cooper Mountain Elementary School
Cooper Mountain Elementary School, part of the Beaverton School District, serves kindergarten through fifth grade as a regular public school. It sits within Beaverton, a mid-sized city in the Tualatin Valley that is part of the Portland metropolitan area and the so-called Silicon Forest, home to major technology firms and Nike’s global headquarters. The school draws its students from the surrounding neighborhoods of this largely suburban community.
On the Oregon state assessments administered in the 2024–2025 school year, Cooper Mountain Elementary’s students posted results that, taken together, place the school among the strongest in Washington County. Across tested subjects and grade levels, the school’s overall proficiency index ranked in the top quartile relative to districts in Washington County. In English language arts, proficiency rates rose steadily from grade to grade, with third graders reaching a solid majority, fourth graders improving on that, and fifth graders achieving a strong result. Math results were more mixed but still above half of students scoring proficient in each tested grade. Science, which is assessed only in fifth grade, showed a notably smaller share of students meeting the bar. A parent may want to follow up with the school about science instruction and curriculum, as that subject area stands apart from the stronger reading and math outcomes.
The student body is majority white, with a substantial Asian enrollment and smaller shares of Hispanic and multiracial students. Black, Native American, and Native Hawaiian or Pacific Islander students each represent a small fraction of the population. About one in five students qualifies for free or reduced-price lunch, a share that is relatively low compared with many Oregon elementary schools. Data on students with disabilities and English learners was not reported in the available records.
Beaverton itself has a varied texture. The downtown core, anchored by the Beaverton Transit Center and MAX light-rail stations, has seen transit-oriented development including The Round mixed-use project, the Patricia Reser Center for the Arts, and a food cart pod. Much of the city, however, remains car-dependent suburban residential areas and commercial corridors. The city’s largest employer is Nike, followed by the Beaverton School District and several technology and retail firms. Home values in the school’s ZIP code are above the national median and have seen a modest recent decrease, while rents have also softened slightly. The area’s affordability relative to local incomes is tight, consistent with the broader Portland metro housing market.
The Beaverton School District covers a large geographic area beyond the city limits. A parent-relevant change in recent years was the opening of Tumwater Middle School in fall 2021, the district’s ninth middle school, which redrew feeder patterns and increased capacity. That development may affect Cooper Mountain Elementary families when their children move on to middle school.
No information was available in the provided data about programs such as gifted offerings, music, or after-school activities. Likewise, staffing ratios, chronic absenteeism, and disciplinary data were absent. For parents weighing this school, the academic picture is one of above-average proficiency in reading and math for an elementary school in the county, with science as a relative soft spot worth exploring. The school’s enrollment is moderate for its grade band, and its student composition reflects the broader Beaverton community’s diversity.
