System Performance Measures (SPM) and Longitudinal Systems Analysis (LSA) provide data related to how the homeless services system functions. SPM reporting highlights annual data on length of stay, recidivism, homeless services utilization, changes in income, first time homeless, and permanent housing retention/exit rates. The LSA provides critical information about how households experiencing homelessness use the homeless services system. This brief document describes the differences between LSA and SPM Reporting.
LSA reporting uses HMIS data to show how households experiencing homelessness move through the homeless services system in a given year. The annual reports presented below convey data about BTG's system of care and leverage dashboards from HUD's Stella Performance Module (Stella P). More information on Stella P can be found using the links below.
LSA reports utilize dashboards from HUD's Stella P module. Resources to better understand these dashboards and the LSA reports can be accessed from the Stella page of the HUD Exchange, including the Stella Performance Glossary, which defines commonly used terms appearing in the LSA reports.
