Summary

River Mill Elementary School is a K–5 school serving 506 students in Estacada, Oregon, a Clackamas County community roughly 30 miles southeast of Portland, and it is one of two elementary schools in Estacada School District 108.

The school has improved steadily, climbing from the 35th percentile of Oregon elementary schools in 2022–23 to the 60th percentile (286th of 709) in 2025–26 — a gain of 25 percentile points and a move from two stars to three. Students now score above state averages in English language arts (50.0%), math (36.4%) and science (35.1%). Nearly identical results at Clackamas River Elementary School, which sits less than half a mile away and climbed the same 25 points, suggest these gains come from a district-wide effort rather than one building. River Mill Elementary School also spends less per student ($14,701) than every comparable traditional public school nearby — about $3,400 below the average — while matching or beating schools such as Naas Elementary School that spend far more.

Chronic absenteeism has fallen sharply, from 42.5% in 2022–23 to 31.2% in 2024–25, putting the school below both its district and state averages. Students in special education score at the 78th percentile, higher than the school overall. The clearest weak spot is fourth-grade math at 27.2% proficiency, the lowest of any school in its comparison group, while third grade is a genuine strength. Results for students from low-income families, who make up a majority of the school, have swung widely from year to year. The student-to-teacher ratio is 19.4:1.
