Juvenile Justice and Delinquency Prevention Reauthorization Act of 2017

This bill amends the Juvenile Justice and Delinquency Prevention Act of 1974 (JJDPA) to modify and reauthorize through FY2021 juvenile justice programs and activities.

Specifically, it:

• revises and expands the purpose areas of the JJDPA;
• expands membership on the Coordinating Council on Juvenile Justice and Delinquency Prevention to include the Administrator of the Substance Abuse and Mental Health Services Administration and the Secretary of the Interior;
• expands requirements for the Department of Justice's Office of Juvenile Justice and Delinquency Prevention (OJJDP) with respect to the annual report on juveniles in custody;
• modifies the required components of a state's juvenile justice and prevention plan;
• modifies the four core requirements with which a state must comply to receive a full allocation of funds under the State Formula Grant Program;
• broadens the authorized grant purposes under the Incentive Grants for Local Delinquency Prevention Programs to include evidence-based or promising programs on mentoring, parent training and support, or in-home family services; and
• subjects juvenile justice grants to accountability provisions.

The Government Accountability Office must evaluate the OJJDP's performance and audit selected grant recipients.

The bill also amends the Omnibus Crime Control and Safe Streets Act of 1968 to condition a state's receipt of funds under the Juvenile Accountability Block Grant program on compliance with the core requirements of the JJDPA applicable to the detention and confinement of juveniles.
