Designating school building-level McKinney-Vento contacts can be a highly effective best practice for identifying children and youth who are experiencing homelessness, and ensuring full implementation of the McKinney-Vento Act. However, sometimes roles can become muddled. These guidelines were created in response to a request from a State McKinney-Vento Coordinator who confronted challenges clarifying lines of authority and responsibility in school districts that designate school building-level McKinney-Vento contacts (in addition to the required designation of the school district McKinney-Vento liaison). The guidelines are designed to share the relevant laws. and provide a procedure to help maintain clear roles and responsibilities. (author abstract)
