The American Probation and Parole Association is an international association composed of members from the United States, Canada, and other countries actively involved with probation, parole, and community-based corrections in both adult and juvenile sectors. All levels of government including local, state/provincial, legislative, executive, judicial, and federal agencies are counted among its constituents. By taking the initiative, APPA has grown to become the voice for thousands of probation and parole practitioners including line staff, supervisors, and administrators. Educators, volunteers, and concerned citizens with an interest in criminal and juvenile justice are also among APPA's members. APPA will continue to effectively provide services to its constituents. The association represents a strong, unified voice for the field of community corrections. APPA developed the Hardcore Drunk Driving Community Supervision Guide as well as its corresponding free online training.
