of 709 Oregon Elementary Schools

Better than 57% of Oregon elementary schools

Summary

Inavale Community Partners dba Muddy Creek Charter School is a K–5 charter school serving 107 students in Corvallis, Oregon, the smallest school in this comparison group and part of the highly ranked Corvallis School District 509J (11th of 141 Oregon districts, 92nd percentile, 5 stars). The school's own 2025–2026 statewide rank is 304th of 709 — 57th percentile, 3 stars — down from 95th percentile in 2018–2019, so it currently sits mid-tier in a district whose schools range from the 96th percentile to the 43rd.

Science is the clear signature strength: 71.4% of students were proficient in 2025–2026, far above the district's 43.4% and the state's 30.6%, and the highest among nearby tested schools, ahead of Franklin School (61.5%), Kathryn Jones Harrison Elementary School (51.1%), and Bessie Coleman Elementary School (50.9%). English language arts (43.1%) is close to the state average but below the district, and math (31.4%) is below both, ranking 9th of 10 nearby tested schools, ahead only of Monroe Grade School. Grade-level results vary sharply — 5th grade is strong (66.7% ELA, 71.4% science) while 4th grade is weak (21.4% ELA, 14.3% math) — but with only 107 students these figures reflect very small cohorts, so one or two students can swing them.

Chronic absenteeism has improved from 39.2% in 2022–2023 to 27.7% in 2024–2025, now better than district (30.2%) and state (33.5%) rates, though still higher than many peers such as Franklin (14.3%) and Garfield Elementary School (18.3%). Per-student spending is $10,510, well below every nearby school, yet the student-teacher ratio is the lowest in the group at 11. In 2025–2026, male students ranked in the 81st percentile (4 stars) and female students in the 54th, but small enrollment means these subgroup patterns should be monitored rather than read as settled.

GREAT school... rural, place-based curriculum with high parent involvement. Cater to each individual child's ability, lots of field work at local nature refuge and farms, incorporating science and art. Community togetherness fostered. Kids love to go there.... They make learning fun! Close Quote
