Iowa's violator program, which represents a collaborative effort between the courts, parole board, institutions, and community-based corrections, provides a highly structured 6- to 8- week program that focuses on changing the offenders' fundamental thinking. Changes in thinking provide the basis for other necessary changes in the offenders' environment such as belief systems, relationships, social and vocational skills, and substance/abuse, addiction or other specifically identified treatment needs. The program mission is to divert certain offenders from imminent longer term incarceration by providing exposure to attitudinal and/or substance addiction relapse treatment in an intensive 60-day program. Proposed legislative amendments as well as the administrative rules are outlined. 4 appendixes
