Hi Tina,
In my current role at the Chadwick Center, we are working with 5 child welfare jurisdictions across the country, including CA, FL, MN, OK, and RI. While there has been discussion about screening for ACEs, and implementing trauma screenings in general, I am not aware of any system (at least in our project) that has implemented ACE screening across the board. I have heard about individual workers in MN and OK who have used the ACE screen as a way to gather information from parents about their own trauma histories, as well as their child/children, however, this is not a system wide practice. The workers I have talked to have reported that it has helped with engagement and creating a dialogue between them and the parents about how their own trauma history may be impacting their parenting. I think it's a fascinating idea, and as more and more systems begin to implement other evidence-based trauma screeners, I think ACEs will probably get more attention as a result.
Hope this helps! Jen
