Summary:
ZIP code 97707 in the Sunriver area has a single elementary-level school: Three Rivers Elementary School, a K–8 campus serving 421 students as part of Bend-LaPine Administrative School District 1. Because there is only one school here, there are no local comparisons to make; the useful benchmarks are the district and the state.
Three Rivers is a top-quartile Oregon school, ranked 172nd of 709 schools statewide for 2025–2026 — the 76th percentile with 4 stars. That is a clear step up from 2023–2024, when it was 236th of 710 with 3 stars, and it has held steady at 4 stars for two years. Its 76th percentile matches its district's, which itself ranks 34th of 141 in Oregon. In all-grade testing, the school beats the state in English Language Arts (51.4% vs. 43.8%), math (39.2% vs. 32.9%), and science (34.4% vs. 30.6%), but trails its own district in ELA by 1.6 points and math by 4.3 points, while edging ahead in science by 0.7 points.
Early literacy is the standout: 4th grade ELA is 71.4%, far above both district and state, and 3rd grade ELA is 60.9%. Sixth-grade math is another bright spot at 44.2%, above the district's 40.5%. The clearest weak spots are the middle grades — 7th grade ELA at 33.3% and 7th grade math at 28.9% both fall below district and state, and 8th grade ELA at 38.6% is also below both. Chronic absenteeism is 35.4%, slightly above the district's 34.2% and the state's 33.5%, and more than one in three students is chronically absent. Nearly half of students (47.98%) qualify for free or reduced lunch, spending per student is $17,474, and the student-teacher ratio is 18.7.
