Residential mobility that results in changing schools has serious implications for a student's academic success. The lack of housing that the lowest income households can afford contributes to housing instability resulting in frequent moves and, for some families, periods of homelessness. Federal housing policy does not provide resources needed to address the shortage of affordable housing and in some cases directly destabilizes housing for low-income families. While school-based strategies can intervene in reducing school changes for some students, housing-based strategies including major new federal investment in low-income rental housing assistance and rental housing production are required.
