CASA volunteers undergo a thorough training and development program that consists of at least 30 hours of pre-service training, followed by 12 hours of yearly in-service training to become recertified. Volunteers learn about courtroom procedure from the principals in the system: judges, lawyers, social workers, court personnel and others. CASA volunteers also learn effective advocacy techniques for children, and are educated about specific topics ranging from seminars on child sexual abuse to discussions on early childhood development and adolescent behavior. After completion of the initial training, volunteers are sworn in as officers of the court. This gives the CASA volunteer the legal authority to conduct research on the child’s situation and submit reports to the court.
