This manual is intended to support data collection and reporting efforts of Homeless Management Information System (HMIS) Lead Agencies and U.S. Departments of Housing and Urban Development (HUD) and Veteran Affairs (VA) programs administering HUD-VA Supportive Housing (HUD-VASH) vouchers. The HUD-VASH program combines Housing Choice Voucher (HCV) rental assistance for homeless Veterans with case management and clinical services provided by the Department of Veterans Affairs (VA). VA provides these services for participating Veterans at VA Medical Centers (VAMCs) and community-based outpatient clinics.
