Original Research by School Decision on Bonny Slope Elementary School
Bonny Slope Elementary School is a regular public elementary school in Portland, serving kindergarten through fifth grade and operating as part of the Beaverton School District 48J. The school sits within the city of Portland’s west side, in an area that feeds into the Beaverton district system. Academic performance stands out as a clear strength. On the state assessments administered in the 2024-2025 school year, proficiency rates in English language arts, math, and science were well above the average among districts in Washington County, placing Bonny Slope in the top quartile relative to its county peers. Reading and writing proficiency was consistently strong across third through fifth grades, and math proficiency showed similarly high levels, with fourth-grade scores particularly high. Science, tested in fifth grade, also reflected a solid performance. While only a single year of assessment data was available, precluding a trend analysis, the current results establish the school as a high-performing option for elementary-age students.
The student body, numbering several hundred children, is diverse. White students make up the largest share, followed by a substantial Asian population, and smaller but notable proportions of students who are Hispanic, two or more races, Black, Native Hawaiian or Pacific Islander, and American Indian or Alaska Native. The school serves a comparatively low share of students from low-income households, based on free or reduced-price meal eligibility, which reflects the surrounding neighborhood’s economic profile. Data on students with disabilities and English learners was not available for this profile, so families should seek that information directly from the school to understand the full range of support services.
The housing market in the school’s zip code is expensive, with home values well above state and national benchmarks and rents also on the high side. Affordability is a real consideration for families looking to move into the attendance area. Portland itself is a large, walkable, transit-connected city with a strong civic infrastructure and a diverse economy anchored by technology, healthcare, and apparel companies. The broader metro area has seen some population decline since the 2020 census, but growth continues in outlying areas and along transit corridors. The city manages development with an urban growth boundary, and housing costs have risen notably in recent decades.
For elementary-level data points beyond academics, the available record is thin. Information on discipline, staffing ratios, attendance, and chronic absenteeism was not included in the data provided, so a parent interested in school climate or class sizes would need to follow up with the school or district. The Beaverton district, which Bonny Slope is part of, recently opened a new middle school—Tumwater Middle School—in fall 2021, which redrew some feeder patterns. This change could affect the transition pathway for Bonny Slope families when students reach sixth grade, and the current middle school assignment is worth confirming.
Bonny Slope Elementary fits families who prioritize strong academic outcomes and a diverse, relatively affluent student environment in an urban but expensive housing market. The school’s high proficiency rates, especially in literacy and math, make it a competitive choice within the Beaverton district and across Washington County. However, the lack of publicly reported data on special education and English learner services means that parents with children who may need those supports should seek specific information from the school. For those who can navigate the housing market, this school offers a strong academic foundation in a well-connected Portland neighborhood.
