Juvenile Justice Reform Act of 2017

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

Specifically, it:

• revises and reauthorizes through FY2022 programs and activities under title II of the JJDPA, including the State Formula Grant Program and the activities of the Department of Justice's Office of Juvenile Justice and Delinquency Prevention (OJJDP);
• revises and expands the purpose areas of the JJDPA;
• expands membership on the Coordinating Council on Juvenile Justice and Delinquency Prevention to include the Assistant Secretary for Mental Health and Substance Use and the Secretary of the Interior;
• expands requirements for the OJJDP's 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; and
• repeals the Juvenile Delinquency Prevention Block Grant program.

The bill revises, restructures, and reauthorizes through FY2022 programs under title V of the JJDPA, including the Incentive Grants for Local Delinquency Prevention Program.

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

The bill subjects juvenile justice grants to accountability provisions.

Finally, it reauthorizes through FY2022 programs and activities: (1) for missing and exploited children, under title IV of the JJDPA; and (2) for runaway and homeless youth, under title III of the JJDPA.
