A more thorough explanation:

A court-appointed special advocate, also known as CASA, is a volunteer who is trained to represent the interests of a child in a case involving abuse or neglect. They are appointed by a court to ensure that the child's needs are being met and that their voice is heard in court proceedings.

For example, if a child is removed from their home due to allegations of abuse or neglect, a CASA volunteer may be appointed to advocate for the child's best interests. The CASA volunteer will gather information about the child's situation, attend court hearings, and make recommendations to the court about what they believe is in the child's best interest.

CASA volunteers are an important part of the child welfare system, as they provide a voice for children who may not otherwise have one. They work to ensure that children are safe, healthy, and able to thrive in a stable and loving environment.
