Disability services and juvenile justice occasionally have clients who require the services of both programs. Establishing a protocol fosters a coordinated and effective service delivery to both children and young people. The protocol is a working agreement to be adopted by direct service workers, supervisors, and managers in juvenile justice units and centers, and disability service client services teams. This paper outlines this Australian protocol by describing the key points of contact between juvenile justice and disability services. The paper is comprised of nine major sections: (1) aim of protocol; (2) definition of juvenile justice and disability services clients; (3) principles of juvenile justice service delivery for young people with an intellectual disability; (4) referral procedures from both juvenile justice and disability services; (5) young people in the juvenile justice system who may benefit from the services provided by disability services; (6) specific points in the juvenile justice system where young people may require services from disability services; (7) dispute resolution; (8) implementation of protocol; and (9) training. Appendices follow which include: (1) The Children and Young Person Act 1989-Provisions Related to Young Offenders; (2) juvenile justice-core functions; (3) juvenile justice rural and metropolitan regional units and centers; (4) disability services-core functions; (5) disability services client service teams; (6) indicators of intellectual disability; (7) juvenile justice checklist; and (8) disability services checklist.
