Summary

Riverdale High School is a small public high school in Portland, Oregon, serving grades 9–12 with 159 students as part of Riverdale School District 51J, the top-ranked district in Oregon. The school is ranked #4 of 271 Oregon high schools in 2025-26 with a 5-star rating, and its rank history is unusually stable: #4, #5, #4, #8 and #5 over the last five listed years, with top-10 finishes in 9 of 10 listed years.

Academically, Riverdale posts very high OSAS proficiency rates: 83.9% in ELA, 51.6% in math and 87.1% in science, compared with statewide rates of 43.8%, 32.9% and 30.6%. Its ELA rate is the highest among nearby schools, ahead of Lakeridge High School (78.3%) and Lake Oswego High School (78.2%). Science is the standout: Lincoln High School, the next closest nearby school, sits at 62.8%. Math is strong but not the local leader, with Lakeridge (53.0%) and Lake Oswego (53.3%) slightly ahead, and it trails the lower-performing nearby schools by a wide margin. Graduation was 100% in 2024-25, the highest among nearby schools.

Resources are a defining feature: $30,701 per student — the highest in the comparison group — and a 9.4-to-1 student-teacher ratio, versus 16.8–20.0 at larger nearby high schools such as Ida B. Wells-Barnett High School, which enrolls about 1,650 students. Chronic absenteeism is 25.7%, better than the state (33.5%) and most nearby schools but higher than Lake Oswego High (20.4%) and the district (16.2%). Math relative to its own ELA and science results, attendance, and the lack of free/reduced-lunch data are the main things to watch.
