Researchers and advocates have linked state guidelines on minimum acreage for schools to the abandonment of historic schools and increased barriers to walking and biking to school. This study examined how the elimination of minimum acreage standards in four states affected school planning processes and outcomes using mixed methods. We found that states changed school acreage policies because of concerns about sprawl and the rising costs of education facilities. However, changes in state acreage policies have not been accompanied by changes in district-level school planning processes and therefore on-the-ground impacts have been minimal in the years immediately after the policy change.
