(1) The purpose of these rules (OAR 413-040-0000 to 413-040-0076) is to define the minimum requirements for developing and maintaining a service plan. The service planning process requires that the worker and the family identify key problem issues, determine the objectives to be achieved, and agree upon the actions to be taken. "Family" includes the legally recognized parent or guardian and the children who are capable and whose needs require them to participate in the planning process, as well as other family members when required. Exceptions to the involvement of the parents are included in these rules. A service plan must directly address a caregiver's functioning in the parental role as it relates to the child's needs for safety, permanence, and well-being. There must be a logical and clear relationship between the service plan and the presenting child welfare issues. When a child is a ward of the court, the service agreement or letter of expectations supporting the service plan must be related to the reasons for court jurisdiction.
