Summary

Imbler Charter School is a K–12 charter school serving 325 students in Imbler, Oregon (ZIP 97841), a small rural community in eastern Oregon's Grande Ronde Valley, and it is the only school in Imbler School District 11 — meaning every district figure is also the school's figure. The nearest comparison point is Cove Charter School, 13.74 miles away in Cove School District 15, a near-twin: also K–12, also a charter, also the only school in its district, with 290 students.

On the headline measures, Imbler's results sit well above Oregon's. The school has posted a 100% graduation rate for five straight years, against a state rate in the low 80s; Cove reported 96.4% in 2024–2025. Chronic absenteeism runs at less than half the state rate — 15.7% in 2024–2025 versus 33.5% statewide, and better than Cove's 20.5%. On 2025–2026 state tests, all-grades proficiency is 65.4% in English language arts, 53.8% in math, and 45.7% in science, versus state rates of 43.8%, 32.9%, and 30.6%. Imbler spends $21,351 per student, about $2,947 less than Cove, with a lower student–teacher ratio (13.8 vs. 15.2).

A few details are worth watching. Grade 8 English language arts is the only spot where the school falls below the state (38.1% vs. 41.5%), and grade 5 is roughly at par. Results are strongest in grades 7 and 11 — 11th grade math is 75.0% against a state rate of 22.9%. The share of students eligible for free or reduced lunch rose from 23% in 2022–2023 to 40.62% in 2024–2025 without any dip in performance. Because the school is small, individual grade-level percentages can swing on a few students, so the repeating patterns — graduation, attendance, and above-state proficiency — are the most reliable.
