Summary:
Three high schools serve grades 9–12 in West Linn-Wilsonville School District 3J, a district ranked 7th of 141 Oregon districts (95th percentile, 5 stars) for 2025–26. Together the campuses enroll 3,227 students: West Linn High School (1,809 students, 56% of high school enrollment), Wilsonville High School (1,258, 39%), and Riverside High School (160, 5%).
West Linn High School is the academic anchor: 26th of 271 high schools (90th percentile, 5 stars), a 98.6% graduation rate, and the highest proficiency of the three in ELA (69.5%), math (39.9%), and science (53.7%), plus the lowest free/reduced lunch rate at 15.7%. Wilsonville High School is steady at 67th of 271 (75th percentile, 4 stars) with a 95.9% graduation rate and strong ELA at 65.8%, but its science score of 31.9% is 13.4 points below the district 11th-grade figure. Riverside High School made the biggest jump, rising from 183rd, 32nd percentile, 2 stars in 2024–25 to 82nd, 70th percentile, 4 stars in 2025–26, with science at 48.9% above district and state 11th-grade averages; its graduation rate is not reported.
For parents, a few cross-school patterns stand out. Math is the shared weak spot: Wilsonville (34.3%) and Riverside (27.3%) fall below the district 11th-grade math figure, and every school’s math score trails its own ELA score. Chronic absenteeism is higher at all three high schools (34.9% to 38.4%) than the district’s 25.9%. Resource levels differ sharply — West Linn spends $17,453 per student with a 19.4 student-teacher ratio, Wilsonville $19,473 with 17.2, and Riverside $35,674 with 10.4 — while Wilsonville and Riverside have nearly identical free/reduced lunch rates near 43%.
