About Our Jail Diversion Model

Program History

Advocates launched the first Pre-Arrest Co-Responder Jail Diversion Program (JDP) in Massachusetts in 2003 at the Framingham Police Department. The model was successfully replicated in Marlborough (2008), Watertown (2011), Natick (2018), and offered on a regional basis in Ashland, Sherborn, Holliston, Hopkinton (2015), Hudson / Sudbury (2018), and Franklin / Medway.  In 2018, the new Co-Response Training and Technical Assistance center was launched to expand replication efforts throughout Massachusetts.

The Model

The only co-responder jail diversion model in Massachusetts, Advocates JDP pairs police officers with masters-level clinicians who ride alongside officers on all calls involving individuals in a mental health or substance-related crisis. They provide much needed de-escalation, crisis stabilization, assessment/evaluation services and on-the-job training. Advocates Jail Diversion Program is also the only model operating in the Commonwealth that facilitates dual diversions - both from arrest and from emergency departments.

Arrest & Emergency Department Diversion

By providing treatment-based alternatives, clinicians are able to facilitate arrest diversions and reduce costly and unnecessary referrals to hospital emergency departments. Individuals who are not able to be diverted from arrest also receive support, resources, and referrals while in police custody.


Program Need

A disproportionate number of individuals in the Massachusetts criminal justice system have behavioral health disorders. Police officers often receive little training and limited resources to respond to calls involving these individuals.

42% of inmates in the county jail system have a form of mental illness.

26% have major mental illness.

Since 2003, 4,017 individuals have been diverted from arrest or from hospital emergency departments. In the JDP communities, the total estimated cost savings is $11.2 million since inception.

Police Satisfaction

“The Framingham Police would not be able to fulfil its mission of keeping Framingham safe without the Jail Diversion Program... The ability to immediately divert low-level offenders away from arrest- and into treatment- benefits everybody.” Kenneth Ferguson, Chief of Police, Framingham Police Department

Officers cite the immediacy of the response, their familiarity with the clinicians, and the clinicians’ ability to de-escalate situations as the most important components of the JDP model.

93% of JDP Police Officers found the clinician helpful

Culture Change

A study was conducted in Ashland, Sherborn, Holliston, and Hopkinton (ASHH) to measure the effects of the Jail Diversion program on police officer attitudes towards the mentally ill in five different categories: Compassion, Kindness, Perceived Dangerousness, Community Inclusion, and Tolerance. One of the most significant changes was in the “Compassion” category, which increased by 15% after one year of the JDP program.

Overall, the program has shown a beneficial and positive impact for police officers and by default is impacting the way they view and respond to calls for service involving individuals in a behavioral health crisis. To view more data, please download our Police Culture Change fact sheet.

Program Replication

As communities have recognized the need for and value of police and mental health partnerships, Advocates has replicated and adapted its successful Framingham Jail Diversion program in a number of communities. The Advocates Jail Diversion team created a step-by-step toolkit to assist communities in the process of developing and implementing their own Jail Diversion programs. The toolkit is available through our Co-Response Training and Technical Assistance Center.

Co-Response Training and Technical Assistance Center (CR-TTAC)

Launched in 2018, the Advocates Co-Response Training and Technical Assistance Center (CR-TTAC) is the first and only hub for the Jail Diversion Co-Responder Model and Mental Health First Aid (MHFA) training in Massachusetts. The Center expands Advocates’ successful Jail Diversion model and offers a unique opportunity for police departments to receive evidence-based Mental Health First Aid trainings to better serve their community.  To learn more about how the CR-TTAC can assist in bringing a Jail Diversion Program to your community please contact Katelyn Dehey, CR-TTAC Manager at KDehey@advocates.org.  For more information about the center please download our CR-TTAC Fact Sheet.
