The Massachusetts Police Accreditation Commission has renewed the Chelsea Police Department’s state accreditation. The commission administers a self-initiated voluntary accreditation process in which participating Massachusetts police departments are evaluated as to whether they are meeting professional standards in their management, operations, and technical support in areas including policy development, emergency response planning, training, communications, property and evidence handling, and use of force. Departments first seek certification and are then eligible to apply for accreditation, a higher award for which they must meet additional standards. Chelsea was certified in 2003, recertified in 2005, and accredited for the first time in 2010. The department is one of only 37 statewide to be accredited, and one of nine of the 35 major city police departments to attain that status. “Achieving accreditation from the Massachusetts Police Accreditation Commission is a very significant accomplishment and a recognition highly regarded by the law enforcement community,” Donna Taylor Mooers, the group’s executive director, said in a statement.
