About Us
The Interstate Compact for Adult Offender Supervision (ICAOS) is the national system that governs the transfer and supervision of probationers and parolees across state lines. Through a legally binding agreement among states and U.S. territories, ICAOS ensures that individuals under supervision who relocate to another jurisdiction remain accountable while supporting public safety and effective supervision practices.
The original compact regulating interstate supervision was established in 1937, making it one of the nation’s oldest interstate agreements. In 2002, states modernized the compact and created the Interstate Commission for Adult Offender Supervision, the governing body responsible for administering and enforcing the compact nationwide.
Today, ICAOS is enacted in all 50 states, the District of Columbia, Puerto Rico, and the U.S. Virgin Islands, creating a uniform framework for managing the movement of supervised individuals between jurisdictions. The Commission establishes rules that carry the force of statutory law in member states, ensuring consistency in how interstate supervision is administered.
The Commission works with member states to:
-
Establish and enforce uniform rules governing interstate supervision
-
Support collaboration among states to manage individuals who relocate across state lines
-
Provide training and guidance to state officials and criminal justice partners
-
Facilitate data collection and information sharing through national systems
-
Promote policies and practices that strengthen public safety and supervision outcomes
-
