Summary

Klamath Union High School is a grades 9–12 comprehensive high school on Monclaire Street in Klamath Falls, Oregon, enrolling 671 students as one of two high schools in Klamath Falls City Schools. It currently ranks 51st of 271 Oregon high schools (81st percentile, 4 stars) — a top-quintile position it has now held for three straight years, after sitting near the 30th percentile in 2021–22 and 2022–23 — and it does this with essentially its entire student body (99.85%) qualifying for free or reduced-price lunch.

Academically, the results are strong: 11th graders scored 65.9% proficient in English language arts versus 46.0% statewide, 50.0% in science versus 33.8%, and 29.1% in math versus 22.9%. Among the three similarly sized comprehensive high schools in the area, Klamath Union places second in every subject, behind Henley High School and ahead of Mazama High School. It posts nearly identical ELA proficiency to Klamath Learning Center (65.9% vs. 64.7%), even though that alternative setting a mile and a half away graduates only 53.8% of its students.

The gap is completion. Chronic absenteeism is 46.0% — 12.5 points above the state — and has risen three years running, while the graduation rate is 82.0%, just below the state's 83.0% and far below Mazama High School (97.9%), Henley High School (97.7%) and even Bonanza Junior/Senior High School (97.0%), a school with much lower test scores. Klamath Union spends $25,657 per student, more than either neighbor, and has improved its student–teacher ratio to 19.4:1. Its low-income students rank in the top quartile statewide (75th percentile, 4 stars), and its special education students have climbed from the 5th percentile in 2017–18 to the 48th in 2025–26. The classroom program is working; getting students to show up is the clear next step.
