Summary

Cheldelin Middle School is a 6th–8th grade school with 488 students at 987 Conifer Blvd NE in Corvallis, Oregon, part of Corvallis School District 509J, a district ranked 11th of 141 in the state. Cheldelin holds 4 stars for 2025-2026 and ranks 98th of 371 Oregon schools (74th percentile) — a step down from a long run in the 85th–95th percentile every year from 2014-2015 through 2024-2025, peaking at 5 stars in 2016-2017.

On state tests, Cheldelin is above the Oregon average in all three subjects — ELA 51%, math 36.5%, science 40.4% — but below its own district in all three (52.5, 43.6, 43.4). Against its in-district neighbor Linus Pauling Middle School (1.66 miles away), the two have converged: 74th vs. 73rd percentile this year, with nearly identical demographics, staffing, and per-pupil spending. Cheldelin has a clear attendance advantage (27.6% chronic absenteeism vs. 32.9%) and stronger ELA, while Linus Pauling holds a small math and science edge. North Albany Middle School (7.1 miles away) serves more low-income families — 75.6% free/reduced lunch vs. Cheldelin's 57.6% — yet posts higher proficiency in every subject, lower absenteeism, and spends about $1,500 less per student ($18,713 vs. $20,243). Cheldelin has the highest per-student spending in the comparison group, though spending figures may include district-level allocations and aren't a clean efficiency measure.

Attendance is Cheldelin's most durable strength: 27.6% chronic absenteeism beats the district (30.2%) and the state (33.5%), and it has beaten both in four of the last five reported years. The clearest academic soft spot is math, especially 8th grade, where 30.1% proficiency sits only 0.1 points above the state (30.0) and 9 points below the district (39.1). Worth noting as context: free/reduced lunch eligibility rose from 31.23% to 43.18% to 57.58% over three years, so today's student body differs from the one behind the school's earlier peaks.
