How can we better respond to the trauma running through our criminal legal system? That has been a long-time concern of our teams of reformers who travel across the country offering guidance to judges, clerks, lawyers, and other court staff looking for less harmful, more responsive ways to deliver justice. Part of the Trauma-Informed Practice Strategy Lab, this document presents lessons from a national scan of criminal courts working to better support people with histories of trauma. The guide will inform an upcoming blueprint for making trauma-informed approaches in court work on the ground.
