Summary:
If you live in ZIP code 97267 (Milwaukie, Oregon) and have a child in grades 6–8, there is exactly one in-boundary middle school option: Alder Creek Middle School, which serves about 810 students and belongs to North Clackamas School District 12. Because it is the only middle school in this ZIP code, there is no local comparison to make — the useful benchmark is how Alder Creek compares with its own district and with Oregon as a whole.
On the 2025–26 state tests (OSAS), Alder Creek scored below both its district and the state in all 10 reported subject-and-grade results. Overall proficiency was 29.1% in English language arts, 21.5% in math, and 11.1% in science. The weakest results are in 8th grade: 17% proficient in ELA and 11.1% in science, gaps of roughly 24 and 17 points below the state. Scores also fall as grade level rises — ELA drops from 36.9% in 6th grade to 17.0% in 8th, and math from 27.7% to 17.0%. The closest thing to a bright spot is 6th grade math at 27.7%, only about 2 points below the state. Chronic absenteeism is 34.7%, slightly above both the district (30.5%) and state (33.5%), and 59.01% of students qualify for free or reduced-price lunch.
Two things stand out for parents. First, the district itself performs at or near state averages, so these results reflect this school specifically rather than a district-wide pattern. Second, the school spends $21,569 per student with a 17.7-to-1 student–teacher ratio, yet outcomes remain below average — and the ranking trend is slowly improving, moving from the 14th to the 22nd percentile of Oregon middle schools over three years. That is encouraging, but it still means roughly 78% of ranked middle schools scored higher in 2025–26.
