Chester County's Crisis Intervention Team (CIT) program has received Silver Certification through CIT International for achieving many best practices of CIT programming. Chester County's CIT program is a community partnership of law enforcement, Chester County Human Services professionals, and court-related staff members who are trained to improve community response to individuals experiencing mental health crises. The program is designed to help people receive treatment rather than prison time.

Law enforcement officials from 37 of the county's police departments, the Pennsylvania State Police, and West Chester University Police have received CIT training, along with representatives from many county departments, including Chester County Prison corrections officers, county park rangers, and staff members from the county's Probation, Parole, and Pretrial Services; Veterans Affairs; Sheriff's Office; and 9-1-1 Center. More than 350 people have completed the program.

The 40-hour training program is offered twice per year and consists of classroom learning as well as scenario simulations. Topics include laws related to mental health and how to interact with someone in crisis.

Chester County's CIT training program began in 2017 following the formal commitment made by the Chester County Commissioners to become part of the national Stepping Up Initiative. Stepping Up advances county efforts to reduce the number of adults with mental and co-occurring substance use disorders in jails. It is a collaboration led by the National Association of Counties, the Council of State Governments Justice Center, and the American Psychiatric Association Foundation.
