Best Public Schools in Sunriver, OR

Sunriver, Oregon is a single-school community: the area has just 1 public school — 1 elementary, 0 middle, 0 high, and 0 alternative — so every public-school student in town attends the same building. That building is Three Rivers Elementary School (56900 Enterprise Dr, Sunriver, OR 97707), a K–8 school with 421 students serving nine grade levels (roughly 47 students per grade) within Bend-LaPine Administrative School District 1. Because there is only one school, parents should read its results against the district and state benchmarks rather than against other local schools.

Academically, the school sits in Oregon's top quartile: it ranks 172nd of 709 schools (76th percentile, 4 stars) in 2025-26, up from 236th of 710 (67th percentile, 3 stars) in 2023-24, with the gain coming between 2023-24 and 2024-25 and holding steady since. It beats the state average in 11 of 14 grade-subject combinations, including all three overall subjects — English Language Arts (51.4% vs. 43.8%), math (39.2% vs. 32.9%), and science (34.4% vs. 30.6%). Its standout result is 4th grade ELA at 71.4% proficient, 27.9 points above the state. However, it trails its own district in 10 of 14 grade-subject cells, and results are front-loaded: 3rd and 4th grade ELA are far above state, while 7th and 8th grade ELA (33.3% and 38.6%) fall below it, with 7th grade ELA 25.3 points behind the district. Sixth grade math (44.2%) is the one middle-grade bright spot, beating both district and state.

Context matters as much as scores. Chronic absenteeism is 35.4% — above both the district (34.2%) and the state (33.5%) — meaning strong achievement is happening despite an attendance headwind. About 47.98% of students qualify for free/reduced lunch, per-student spending is $17,474 (roughly $7.36 million for the enrollment), and the student-teacher ratio is 18.7:1, implying about 22–23 teachers. For parents, the takeaway is a well-regarded, improving school in a strong district whose main opportunity is its 7th and 8th grade results.
