Foster care agencies are organizations that help find temporary homes for children who cannot live with their biological families. These agencies work with social workers, families, and the court system to ensure that children are placed in safe and nurturing environments. They also provide support and resources to foster families to help them care for the children. In addition to placing children, foster care agencies offer training and guidance for foster parents. They help families understand the needs of children in care and provide ongoing support to ensure the well-being of both the children and the foster families.
