This manual is a reference tool to provide basic guidance on data collection for Runaway and Homeless Youth (RHY) Program service providers who are using the integrated Homeless Management Information System (HMIS) data system to capture youth data. The HMIS data collection system is used as the primary means for recording and reporting information about the needs, critical issues, and support received by runaway and homeless youth who are served by the RHY grant programs. The Street Outreach, Basic Center, and Transitional Living Programs are authorized to capture and report data to the Administration on Children, Youth and Families (ACYF) by the Runaway and Homeless Youth Act (P.L. 108-96) which was reauthorized in 2008. HMIS replaces the former Runaway and Homeless Youth Management Information System (RHYMIS) desktop system.
