Annex School District 29

Annex School District 29 is a single-school district in Oregon, and its only campus, Annex Charter School in Ontario, serves 131 students in grades K–8 even though it is classified as an elementary school. Because the district contains just this one school, district and school figures for test scores and attendance are identical. The district overall is rated 4 stars, ranking 41st of 141 Oregon districts, in the 71st percentile.

Student achievement is above state averages overall. On 2025–2026 OSAS tests, all-grade proficiency was 48.9% in English Language Arts (state: 43.8%), 41.3% in mathematics (state: 32.9%), and 36.4% in science (state: 30.6%). Results vary by grade. Third grade is a clear strength, with ELA at 64.3% versus the state's 41.5%. Fourth grade is the weak spot, at 30.8% in ELA (state: 43.5%) and 21.4% in math (state: 38.9%). Fifth grade is mixed — ELA at 40.0% is below the state's 47.1%, while math (40.0% vs. 32.4%) and science (40.0% vs. 30.8%) are above. Results for grades 6, 7, and 8, and for 8th-grade science, were suppressed by the state for privacy, so those are unknown rather than zero.

Attendance is a standout: chronic absenteeism is 10.9%, far below Oregon's 33.5%. The school's rank history also shows a sharp rebound, from 1 star and the 24th percentile in 2024–2025 to 3 stars and the 56th percentile in 2025–2026 — above its 2018–2019 mark of 3 stars and the 51st percentile. Resources reflect a small school: $23,527 in per-student spending, a 16.3 student-teacher ratio, and 48.09% of students qualifying for free/reduced lunch.
