Summary:
ZIP code 97007 contains just one high school: Mountainside High School, a large public school serving grades 9–12 with 1,741 students. It is located in Beaverton, Oregon, and is part of Beaverton School District 48J, which ranks 19th of 141 districts in Oregon — the 87th percentile — and holds a 4-star rating. Because Mountainside is the only high school in this ZIP code, there are no local peers to compare it against; the most useful benchmarks are its district and the state.
Mountainside stands out on several measures. It ranks 60th of 271 Oregon high schools in 2025–2026 — the 78th percentile — and has held a 4-star rating across 2023–2024, 2024–2025, and 2025–2026. Its graduation rate is 93.5%, which is 4.6 percentage points above the district (88.9%) and 10.5 points above the state (83.0%). English Language Arts proficiency is 56.6%, compared with 53.4% district and 43.8% state, while science proficiency is 45.9%, compared with 37.7% district and 30.6% state — a 15.3-point edge over the state. Eleventh-grade math proficiency is 31.8%, above the state's 22.9% and essentially level with the district's 32.3%.
A few data points warrant attention. At the all-grade level, math proficiency is 31.8%, below the district's 43.7% and slightly below the state's 32.9%; for a high school, though, the 11th-grade comparison is likely the more relevant one. Chronic absenteeism is 31.5%, higher than the district's 28.7% but below the state's 33.5%. With 50.32% of students eligible for free or reduced lunch, Mountainside serves a relatively high-need population while still outperforming the state in ELA, science, 11th-grade math, and graduation rate. The school spends $17,324 per student and has a 21:1 student-teacher ratio, though no state or district benchmarks for those figures are included here.
