As required by the federal No Child Left Behind Act (NCLB), all districts have responsibilities to homeless students in the district. In order to serve these students, each district must appoint a liaison for homeless children who reside within a district. The liaison must first identify these students, and, to aid in doing so, post notifications regarding educational services and contact information at places where the parents of homeless students will see them. These locations can include, but are not limited to, homeless shelters, medical clinics, post offices and local Social Service offices.
