Foster care is a system in which children who are unable to live with their biological parents are placed in the care of temporary guardians, known as foster parents. This arrangement is intended to provide a safe and stable living environment for children while their family situation is being resolved. Research in the area of foster care examines issues such as the impact of placement instability on a child's development, the effectiveness of support services for foster families, the experiences of children and youth in the foster care system, and ways to improve outcomes for children in foster care. This research is crucial for informing policy and practice in order to better support children and families involved in the foster care system.
