What is the purpose of the adjudicatory hearing?

An adjudicatory hearing is a legal proceeding to determine a child's state dependency, or whether the child should be placed in the state's custody and receive services such as foster care. Option A is incorrect because the hearing does not solely decide on foster care placement; it also determines if the child is dependent on the state. Option C is incorrect because the hearing does not review the child welfare practice model, but rather the child's situation and needs. Option D is also incorrect because the hearing does not assess quality assurance case reviews, but rather focuses on the child's well-being. Therefore, option B, deciding the state dependency of the child, is the correct answer. This involves analyzing evidence and testimonies to determine if the child is at risk and in need of state care.
