Foster care in the United States

Foster care is the term used for a system in which a minor who has been made a ward or a non-minor, typically aged 18–21, who volunteers for placement, is placed in a relative placement, a non-related extended family (NREFM) placement, a community family home, an institution, or a group home (residential child care community, residential treatment center, etc.). Relative, NREFM, and community caregivers certified by the state are typically referred to as "foster parents," "kin caregivers," "resource parents," or other local terms.
