Currently, 26 states have extended services for those in foster care that allow them to continue to receive services until they are 21 years old. However, it is underutilized.
One program that I encourage anyone interested in helping foster youth is CASA - Court Appointed Special Advocates. CASA programs are in every state (except North Dakota) and DC. It is similar to a Big Brother/Big Sister program as you will be assigned to a foster child. You spend time with the child and submit reports to the judge.
Social workers frequently change as some counties have a system in which a different social worker handles a specific step of the case. The CASA allows for continuity for the child. A CASA can make a huge difference in a child's life.
