Original Research by School Decision on Mountainside High School
Mountainside High School serves students in grades nine through twelve in the Beaverton School District, located in the western Portland metropolitan area. The school’s enrollment is large for a single high school. The student body is predominantly white, with Asian and Hispanic students each making up a notable share and smaller populations of students who are multiracial, Black, Native Hawaiian or Pacific Islander, and American Indian or Alaska Native. Around a quarter of students qualify for free or reduced-price lunch, which is well below the national average and points to a generally more affluent student population. Data on the share of students with individualized education programs and English learners was not available in the records provided.
Academically, the picture is mixed. On state assessments, a majority of students met the proficiency standard in English language arts, which is a solid outcome. In science, more than a third of students met that bar. Math proficiency was lower, with a share of students meeting the standard that many families would consider a soft spot. The school had only a single year of testing data in the record, so there is no trend to examine. No data on high school graduation rate, Advanced Placement or International Baccalaureate participation, dual credit, career and technical education pathways, or college readiness metrics like SAT or ACT scores was available. Because the school sits inside a large district, a parent may want to ask the school directly about the breadth of its course pathways and what support is in place for students who need additional help in math.
The school is part of the Beaverton School District, which has been expanding capacity. A new middle school opened within the district in recent years, redrawing feeder patterns. That kind of boundary change can shift which elementary schools send students to which middle school and, eventually, to which high school. A family living within Mountainside’s attendance area should confirm current feeder assignments with the district.
Beaverton itself is a mid-sized city in the Tualatin Valley that functions as both an economic hub and a bedroom community. It sits in the heart of the region known as the Silicon Forest and hosts a major concentration of technology employers, along with the global headquarters of Nike. The city’s downtown has seen deliberate redevelopment around its light rail stations, with a mix of retail, condominiums, city hall, a performing arts center, and a hotel all clustered near the Beaverton Central MAX Station. A food cart pod adds to the everyday street life. Much of the rest of the city, however, is suburban in character, with car-dependent commercial corridors. The Beaverton City Library, numerous parks and nature preserves, and TriMet’s busiest transit center are all civic anchors. Development continues to focus on densifying along transit corridors, and the city has been growing steadily.
Housing in the area carries a cost well above the national typical home value, and rents are elevated. The estimated typical monthly mortgage payment is higher than the typical rent, which tilts the market toward renting over buying for many households. The local economy has a low unemployment rate and a median household income that sits above the national figure, consistent with a region anchored by high-wage technology and manufacturing employers.
For a family weighing this school, the strongest draw is the community context: Beaverton’s economic stability, the school’s low poverty rate, and a solid English language arts performance point to a school that serves a relatively resourced population. The math proficiency figure is the primary academic concern, and the lack of data on graduation rates and program breadth leaves important questions unanswered. The school is large, so students who want smaller class sizes or more individualized attention may find that less available here. A parent should inquire with the school directly about how it supports students who are not yet at standard in math, what the graduation rate is, and what advanced or career-oriented coursework is actually available.
