The federal McKinney-Vento Homeless Assistance Act ("McKinney-Vento") provides federal funding to states to address the problems that homeless children and youth encounter in enrolling, attending, and succeeding in the nation's public schools. McKinney-Vento requires states to develop plans that ensure homeless children and youth the same access to free public education as is available to other students; eliminate barriers to enrollment, attendance, and success in school; prevent the segregation of homeless students from the mainstream school environment; and provide access to the education and services needed to ensure that homeless students have an opportunity to meet the same academic standards as all other students. Local education authorities (LEAs) are required under McKinney-Vento to ensure that homeless children and youth are immediately identified, enrolled in school, and provided with all necessary services, including transportation, to allow school attendance. This paper discusses the limitations of the McKinney-Vento Act and offers several suggestions on how states can increase homeless children's participation in state-funded Pre-K programs.
