House Bill No. 1574 amends Section 601.6 of Title 10 of the Oklahoma Statutes, enhancing the responsibilities and authority of the Office of Juvenile System Oversight. The bill defines the term "children and youth service system" and mandates the Office to conduct annual inspections of state-operated children's institutions and facilities, as well as inspections of privately operated facilities that receive state or federal funding. The Office is also tasked with investigating complaints, examining records and budgets, interviewing individuals, and has the authority to subpoena witnesses and hold public hearings.

Additionally, the bill introduces a voluntary mediation program for foster parents to address complaints related to the Department of Human Services and child-placing agencies. It establishes a process for the Office to receive and forward complaints regarding potential threats or harassment of foster parents by agency employees. The Office is required to issue reports to various state officials and provide annual recommendations to the Oklahoma Commission on Children and Youth. An emergency clause is included, allowing the act to take effect immediately upon passage and approval.
