About Three Rivers School District
Families in zip code 97534 (O Brien, Oregon) are assigned to Three Rivers School District for public education through 12th. This overview covers the district’s funding levels, scale, rating, and what to expect from the enrollment process if you’re moving to or within this zip code.
Understanding the 4/10 Rating
SchoolDistrictFinder rates Three Rivers School District 4 out of 10 — below average among Oregon public school districts. Our ratings are based on state assessment results — the share of students scoring proficient or above in reading and math, as reported in the U.S. Department of Education’s EDFacts collection (2021–22 school year). We average each district’s reading and math proficiency, then rank it against other districts in the same state to produce a 1–10 score. Because Oregon is compared only against itself, the rating reflects how this district performs relative to its in-state peers.
Three Rivers School District carries a below-average rating, with reading and math proficiency rates below typical Oregon benchmarks on state assessments. A below-average score reflects test performance relative to other districts — not necessarily teaching quality or school culture, and some of these districts have schools with strong communities and dedicated staff. Families should research specific school quality, visit in person, and ask about available programs. Also ask about open enrollment and magnet options that may offer alternatives to the default attendance-zone assignment.
