Summary

Clackamas Middle College is a public charter high school located in Happy Valley, Oregon, serving grades 9-12 with a total enrollment of 282 students. This high-performing school consistently ranks among the top high schools in the state, outperforming nearby traditional public high schools like Milwaukie High School and Putnam High School in academic proficiency and overall school rankings.

Clackamas Middle College's academic excellence is evident in its consistently high 11th-grade proficiency rates in English Language Arts, Mathematics, and Science, which are significantly higher than the North Clackamas School District and state averages. The school also maintains impressive four-year graduation rates, ranging from 81.3% to 98.5% in recent years, outperforming both the district and state averages. Notably, Clackamas Middle College has achieved these impressive results while operating with relatively lower per-student funding and a higher student-teacher ratio compared to nearby traditional public high schools.

The school's strong performance extends across different student subgroups, including female, male, Hispanic, and white students, as well as students from low socioeconomic backgrounds. For example, in 2023-2024, Clackamas Middle College ranked 24th out of 237 Oregon high schools for male students and 10th out of 132 schools for Hispanic students. This consistent excellence across various student demographics suggests that the school's educational model and practices may be worth further investigation and potential replication in other settings.
