About schools in Union County
Spread across the Blue Mountains and Grande Ronde Valley in northeastern Oregon, Union County has a distinctly rural texture — six districts serving small towns like La Grande, Elgin, and Union, with 12 public schools ranked across the county. That modest scale hasn't limited academic achievement: three schools land in the state's top quartile, with Imbler Charter School reaching the 96th percentile statewide and Cove Charter School close behind at the 89th. Island City Elementary rounds out the top tier. For families drawn to smaller school communities with genuinely strong outcomes, Union County rewards a closer look.
