Your state's public flagship
University of Idaho
The in-state tuition gap is the flagship's biggest draw — most in-state families pay far less than the out-of-state sticker. Average net price after aid runs about $14,831/yr. Admission odds depend on your student's GPA and test scores, not which high school they attend.
