School Overview

Annex Charter School sits in the small, tight-knit farming community of Ontario, right on the Idaho border where Oregon's high desert meets the Snake River Valley. With notably strong math performance and solid overall scores for a rural charter school, it's a good fit for families who want an intentional, community-driven alternative to traditional public schooling in this corner of eastern Oregon. Life out here is wide-open and unhurried — if you're drawn to agriculture, outdoor space, and a school where your kid isn't just a number, Annex is worth a close look.
