Clackamas Middle College

Public, Charter Grades 9-12

20^th

SchoolDigger Rank ?

of 271 Oregon High Schools

Better than 93% of Oregon high schools

Summary

Clackamas Middle College is a small public high school serving grades 9–12 with 305 students in Happy Valley, Oregon, part of North Clackamas School District 12. It stands out sharply from its surroundings: the district is rated 3 stars and ranked 48th of 141 in Oregon, while the school is rated 5 stars and ranked 20th of 271 high schools statewide in 2025–2026 (93rd percentile). Among nearby schools, only Cleveland High School ranks similarly.

Graduation and attendance are the school's strongest headlines. Its 97.4% graduation rate in 2024–2025 is the highest in the local comparison — above Adrienne C. Nelson High School (94.9%), Clackamas High School (94.4%), and Milwaukie High School (82.1%) — and 14.4 points above the state. Chronic absenteeism is just 11.1%, roughly a third of the district (30.5%) and state (33.5%) rates, and lower than every nearby school with data. Academically, English Language Arts proficiency is 82.4%, nearly double the district and state rates and the highest locally, ahead of Milwaukie Academy of the Arts and Cleveland. Math, at 40%, is well above district and state averages but below Cleveland's 45.9%, making it the school's relatively weakest subject. Science is 52.9%, above district and state, though Milwaukie Academy of the Arts reports 60.7%.

The school achieves this with less money per student ($17,546) than most nearby comprehensive high schools and a much higher student-teacher ratio (41.2), a striking contrast worth noting without assuming cause. The school ranks in the top 10% of Oregon schools for its effectiveness with several student groups, and its low-income subgroup results have been strong in some years (98th percentile in 2022–2023) but less consistent more recently. Free/reduced lunch data is not reported, so its economic makeup can't be compared directly. Statewide rank has ranged from 13th to 81st in recent years — still above the 70th percentile even in weaker years, suggesting the current high ranking isn't a one-year fluke.
