Riverdale Grade School

Riverdale Grade School earns a composite score of 9.1 out of 10 — rated Exceptional — which places it 40th among 1,226 public schools in Oregon. That ranking puts Riverdale ahead of 97% of Oregon public schools, with its academic subscore of 9.9 doing most of the heavy lifting. Growth rounds out the profile at 8.6, signaling that students make year-over-year gains rather than simply holding ground at an already high performance level.

The school serves 400 students across kindergarten through eighth grade. A 16-to-1 student-teacher ratio runs across that full K–8 span, keeping class sizes in a range where teachers can track individual progress through multiple grade transitions. Riverdale is a regular public school — enrollment is not selective — so these numbers reflect the program's general performance rather than a filtered population.

Within Portland, Riverdale ranks 27th of 148 public schools. Families comparing public elementary options across the city can use that figure as a reliable anchor: Riverdale sits in the top 20% of Portland's public schools and near the top 3% of all Oregon public schools statewide.
