Policy brief from the James A. & Louise McClure Center for Public Policy Research | Idaho at a Glance. 2009. | About two-thirds of Idaho's school districts are rural. Compared to other districts in Idaho, rural districts: tend to have lower enrollments; are more likely to be losing students; tend to spend more per student, despite lower teacher salaries; tend to have smaller class sizes; are more successful at meeting No Child Left Behind targets; and are much more likely to be adopting four-day school weeks. Over one-fourth of Idaho's K-12 students are rural. Compared to other students in Idaho, rural students: score nearly the same on both state and federal standardized tests; are more likely to come from low income families; are just as likely to be "English as a Second Language" students.
