This program is for people using this tool in their agencies: The Service Prioritization Decision Assistance Tool (SPDAT) is an evidence-informed approach to assessing an individual’s or family’s acuity. This tool prioritizes; across multiple components, who to serve next and why - while identifying areas in the person/family’s life where support is most likely needed in order to avoid housing instability. SPDAT uses 15 dimensions to determine an acuity score that helps to inform who would benefit most from Housing First; Rapid Re-housing & who could end their own homelessness with little to no intervention. SPDAT also informs which areas in the person’s life could be the initial focus in the case management relationship to improve housing stability & how individuals and families are changing over time as a result of the case management process.
