This resource was created in 2016 by CSH in coordination with the Metropolitan Washington Council of Governments and the Regional Primary Care Coalition. It was first intended for county and state planning meetings that include leaders from housing, health, and homeless sectors. Each system has its own set of acronyms that its members use fluently in conversation. When bringing multiple systems together for integrated approaches to problem solving using acronyms can lead to confusion around their meaning. Having all commonly used acronyms in one place for leaders to reference helps to keep conversation flowing. The list below includes direct definitions pulled from the sources included in the bibliography. In some cases, definitions were combined or edited for brevity.
