Two data sources were used for the study, data from the 1993 wave of the Law Enforcement Management and Administrative Statistics study and a survey of community police practices in over 1,600 police agencies conducted by the Police Foundation in 1993. A typology of policing innovation was constructed and then tested, with policing innovation defined as something new and state-of-the-art to the field of policing. Policing innovation was categorized according to radical, technical, administrative, and programmatic types. It was apparent police organizational innovation was not a unidimensional construct. Although the innovations were identified as being state-of-the-art, methods in the present study were not. Policing innovation splintered into at least 10 sub-groups. Future studies of policing innovation are recommended to assess the true extent of innovation. 44 references, 7 notes, and 4 tables
