Judges appoint CASA volunteers to advocate for the best interests of children who have been removed from their homes because of abuse, abandonment, and/or neglect. CASA is appointed to children ranging in age from birth to 18, and can advocate for children up to age 21. In 2014, approximately 22,510 children were in Pennsylvania’s foster care system.  Currently there are not enough CASA volunteers to represent all of the children in care, hence, judges typically assign CASA volunteers to their most difficult cases.
