System Performance Measures (SPM) and Longitudinal Systems Analysis (LSA) provides BTG with analysis related to how the homeless services system functions. SPM reporting provides annual data to BTG on length of stay, recidivism, homeless service utilization, changes in income, first time homeless, and permanent housing retention/exit rates. The LSA provides HUD and BTG with 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 leverages BTG's HMIS data to provide insights into how households experiencing homelessness utilize the homeless services system. The annual report below conveys data about BTG's system of care and includes dashboards from HUD's Stella Performance Module (Stella P), which uses dynamic visuals of LSA data to illustrate how households move through the system.
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.
