Summary:

North Clackamas School District 12 serves 31 schools — 19 elementary, 4 middle, 7 high, and 1 alternative — enrolling 16,837 students in the Milwaukie, Happy Valley, and Clackamas area southeast of Portland. The district ranks 48 of 141 in Oregon (3 stars, 66th percentile), with 2025–2026 proficiency of 44.8% ELA, 32.9% math, and 29.4% science, close to statewide figures of 43.8%, 32.9%, and 30.6%. District chronic absenteeism is 30.5%, better than the state's 33.5%, and the graduation rate is 87.9%.

Several schools stand out. Clackamas Middle College ranks 20 of 271 high schools, 5 stars, with 82.4% ELA, 52.9% science, a 97.4% graduation rate, and only 11.1% chronic absenteeism. Milwaukie Academy of the Arts (4 stars) posts 76.3% ELA and 60.7% science. Among elementaries, Happy Valley Elementary School is strongest overall (64.3% ELA, 57.4% math), while Sojourner School has the district's highest elementary ELA at 67.6% and the lowest traditional-school absenteeism at 12.0%. Happy Valley Middle School leads middle schools. Among comprehensive high schools, Adrienne C. Nelson High School leads in ELA and math, and Clackamas High School stands out in science.

The lower tail clusters in parts of Milwaukie and in alternative settings. New Urban High School is lowest: 15.6% ELA, 7.0% math, 59.4% graduation, 78.3% absenteeism. Linwood Elementary School posts 18.3% ELA and 6.9% science, and Whitcomb Elementary School 22.3% ELA with 39.3% absenteeism. Milwaukie High School struggles in math (10.9%) and absenteeism (48.5%), and Alder Creek Middle School and Rowe Middle School trail in science and absenteeism (41.1%). Notably, spending does not predict outcomes: high-spending Oak Grove Elementary and Linwood show weak results, while free/reduced lunch is nearly uniform near 58–59%.
