Social workers are employed by the government and have responsibilities to the entire family. They sometimes are assigned as many as 12-15 cases (20-50 children) at a time. A CASA volunteer will be matched with one child or a sibling group, as their initial case assignment. The CASA volunteer does not replace a social worker/case worker on a case. He or she becomes an additional member of the child’s team. The CASA volunteer can thoroughly examine a child’s case, has knowledge of community resources, and can make recommendations to the court independent of what the case worker or child welfare agency may recommend.
