The SPDAT, or Service-Prioritization-Decision-Assistance-Tool, is an evidence-informed approach to assessing the acuity of an individual’s or family’s homelessness. The tool is used to help case workers and service providers prioritize who to serve next based on their need and identify the areas in the person/family’s life where support is most likely necessary in order to avoid further homelessness and housing instability. To administer the SPDAT, you must have attended a full training.
