Established in 1937 to monitor the few thousand offenders who were permitted to move out-of-state at that time, the ISC is currently responsible for the controlled movement of over 250,000 parolees and probationers. Terms of the ICS authorize administrators to permit convicted offenders to transfer if they have visible means of support, if they had been residents of the receiving State prior to conviction, or if they have families in the receiving State. The ISC is not without problems, however, that concern inadequate funding, limited ability to enforce compliance, and few means to foster improved collaboration among participating agencies. In addition, too little training has been available to educate criminal justice professionals on the correct application of the ISC. The ISC is also plagued by problems related to victim rights and domestic violence offenders. The need for better procedures to manage and enforce the ISC and to promote victim safety is discussed, and examples are cited of State responses to the ISC. Provisions of a proposed new ISC are noted.
