Enhancing crisis response services through co-response integration and support.

The definition of 'co-response' was expanded to explicitly state that participants respond to in-progress 911 calls, 988 calls, and dispatch requests, and to clarify that first responders and human services professionals include specific roles like telecommunicators, law enforcement, firefighters, EMTs, paramedics, social workers, clinicians, nurses, and peer support specialists.

A separate section requiring the University of Washington School of Social Work to develop a statewide internal peer support program for co-response professionals was removed and its content was integrated into the definitions section.

The bill was renumbered from House Bill 1811 to Substitute House Bill 1811, and the reading date was updated from February 3 to February 21, 2025.
