Summary

Clackamas High School is a comprehensive 9–12 school of about 1,280 students on SE 122nd Avenue in Clackamas, Oregon, part of North Clackamas School District 12. Its standout strength is getting students to graduate: 94.4% in 2024–25, above the district (87.9%) and state (83.0%), and the second-highest rate among the district's comprehensive high schools. Chronic absenteeism (30.5%) matches the district, beats the state (33.5%), and is well below nearby Putnam High School (40.5%) and Milwaukie High School (48.5%).

Test results are solidly middle-of-the-pack, with a few bright spots. Science proficiency is 37.0% — well above the district (29.4%) and state (30.6%), and the highest of any comprehensive North Clackamas high school. Eleventh-grade math (30.8%) also runs ahead of the district (24.8%) and state (22.9%). Eleventh-grade English language arts (44.2%) is the comparative weak spot, trailing both. Classes are large: a 26.3 student-teacher ratio, the second-highest among the district's comprehensive highs, though per-student spending is high at $20,952.

On statewide rankings, Clackamas sat in the top 6–10% of Oregon high schools in the mid-2010s but has settled around the 60th percentile. Its one-year drop to the 18th percentile in 2024–25, followed by a rebound to the 63rd in 2025–26, showed up across nearly every student group at once, which points to a one-year effect rather than a lasting change. English learners and special education students post some of the school's strongest relative results, while its gifted and talented students rank lower — a sign the school succeeds more at attendance and completion than at the top end of achievement. Its closest match is Adrienne C. Nelson High School, about two miles away, which edges it in graduation and ELA while Clackamas leads in science.
