The HMIS Data Dictionary is designed for HMIS vendors and HMIS Lead Agency system administrators to identify the data elements required in an HMIS and understand the function and specific use of each element by the appropriate federal partner. The HMIS Data Dictionary should be the source for HMIS software programming. HMIS systems must be able to collect all of the data elements defined in the HMIS Data Dictionary, support system logic identified in this document, and ensure that data collection and the visibility of data elements are appropriate to the project type and federal funding source for any given project. This release of the 2014 HMIS Data Dictionary and Data Manual Version 3 is an update of the 2014 Data Standards where HUD and the federal partners updated the standards to reflect critical changes that were needed in 2015.
The companion document to the HMIS Data Dictionary is the HMIS Data Manual which provides basic guidance on HMIS data elements for CoCs, HMIS Lead Agencies, HMIS System Administrators, and users.
Information about how to “back enter” data for clients who are active in the system as of October 1, 2015 is provided in the accompanying document, Data Entry for HMIS Critical Data Standards Changes. In addition, an accompanying document, Instructions for Mapping Existing HMIS Data for 2014 Version 3 HMIS Data Standards Elements, provides the mapping requirements for two of the Data Element changes approved for 2014 HMIS Data Standards Version 3 (Element 3.17 and Element 4.35A).
