Summary:
ZIP code 97333 in Corvallis contains three public elementary schools — Adams Elementary School, Lincoln Elementary School, and Inavale Community Partners dba Muddy Creek Charter School — all serving grades K–5 within Corvallis School District 509J, a 5-star district ranked 11th of 141 in Oregon. Together they enroll 760 students, but they perform quite differently, spanning the 46th to the 72nd percentile statewide.
Adams Elementary School is the strongest and most consistent of the three, ranked 195th of 709 schools (72nd percentile, 4 stars) and stable over three years. It leads the group in English language arts (48.5%), math (50.0%), and science (41.9%), all above state averages, with 4th grade math at 60.9% as its standout result. Inavale Community Partners dba Muddy Creek Charter School is the most uneven: its science proficiency of 71.4% and 5th grade ELA of 66.7% far exceed district and state averages, but overall math is 31.4%, with 4th grade math at 14.3% and 4th grade ELA at 21.4%. With only 107 students, its grade-level results can swing widely.
Lincoln Elementary School has the highest per-student spending ($22,134) but the lowest current rank — 380th of 709 (46th percentile, 2 stars) — and the lowest overall ELA (40.7%) and science (22.7%) scores; 5th grade math at 46.7% is a bright spot. Attendance is not the differentiator: all three schools have chronic absenteeism below the district's 30.2% and the state's 33.5%. Adams and Lincoln report similar free/reduced lunch rates (57.6% and 57.23%) despite very different results. Inavale's free/reduced lunch rate is not reported in this data and cannot be compared. Overall, Adams is the strongest all-around performer on these metrics.
