The federal government enacted the McKinney--Vento Homeless Assistance Act (MVA) to equip schools with services to help alleviate the many barriers students experiencing homelessness face in pursuit of educational opportunities. Educational agencies use federally mandated liaisons to uphold the provisions of the MVA. Despite the homeless liaisons' importance in facilitating the policy, few studies have examined how liaisons perceive their service area's response to homelessness. This study explored homeless liaisons' perceptions of MVA implementation in their service areas. Researchers invited every homeless liaison in three southern states to complete an online survey focusing on perceptions of MVA implementation and their service area's response to homelessness. Of the 369 practitioners identified as a homeless liaison solicited for study participation, 32 percent completed surveys. Results indicated significant differences in perceived implementation in the level of collaboration with teachers and school administrators, liaisons' job titles, school's receipt of federal Education for Homeless Children and Youth funding, and awareness of homelessness in terms of general awareness, interaction, policy, and needs. Findings indicate that collaboration and awareness are major factors that affect perceptions of implementation. Furthermore, the results indicate that liaisons must take steps to ensure a collaborative environment to implement the MVA.
