Summary

Adrienne C. Nelson High School is a 9–12 comprehensive high school in Happy Valley, OR, serving 1,536 students as part of North Clackamas School District 12. For 2025–26, it ranks 90th of 271 Oregon high schools (67th percentile, 3 stars), matching the district’s percentile. Its graduation rate is 94.9%, well above the district’s 87.9% and the state’s 83.0%, and its chronic absenteeism rate is 28.2%, lower than the district’s 30.5% and the state’s 33.5%. After reaching the 88th percentile in 2022–23, its rank fell to 46th in 2024–25 before rebounding to 67th in 2025–26.

Academically, Nelson’s ELA proficiency is 51.9% (district 44.8%, state 43.8%) and science is 34.0% (district 29.4%, state 30.6%), both above average. Math is mixed: all-grade math is 30.7% (district and state 32.9%), but 11th-grade math is 30.7% (district 24.8%, state 22.9%), above both. The school’s latest subgroup effectiveness rankings show 75th percentile for Gifted and Talented, 72nd for Hispanic students, and 69th for Low Socio Economic Status students, while Multi-racial (31st) and English Language Learner (26th) students rank lower; several groups are small, so year-to-year swings should be interpreted cautiously. Resource context: the student-teacher ratio is 27.1, higher than most nearby schools except Clackamas Middle College (41.2), and per-student spending is $19,186. The reported free/reduced lunch rate rose sharply to 58.46%.

Compared with nearby schools, Nelson outperforms most comprehensive high schools on ELA, graduation, and attendance, including Putnam High School and generally Clackamas High School. However, West Linn High School (98.6% graduation, 69.5% ELA) and Clackamas Middle College (97.4% graduation, 82.4% ELA) are the clearest academic benchmarks nearby, both ranking in the top 30 statewide. Some nearby data are suppressed or bounded: Oregon City Service Learning Academy reports test scores under 5%, and Clackamas Academy of Industrial Sciences has 11th-grade math under 5%. Overall, Nelson is a solidly above-average Oregon high school with strong graduation and attendance, above-average ELA and science, and math that is stronger at the tested 11th-grade level than the all-grade figure suggests.
