HMIS data standards have been established by the U.S. Department of Housing and Urban Development (HUD), the U.S. Department of Health and Human Services (HHS), and the U.S. Department of Veterans Affairs (VA) to allow for standardized data collection across systems about individuals and families experiencing homelessness. The HMIS Data Dictionary and the HMIS Data Standards Manual are the documentation of requirements for the programming and use of all HMIS and comparable database software.
The HMIS Data Standards & HMIS Data Dictionary can be viewed on this page of the HUD Exchange.
