This is one of the most satisfying volunteer positions you can find. Basically, once a child is placed in the foster system, if the situation is critical enough, they are assigned a CASA. Your job as a CASA is to track this child through their foster homes - meet with the parents, teachers, doctors, foster home, etc. and help the courts determine the best placement for this child. I can't tell you how many children need a CASA right now - the demand is always much higher than the supply, which is tragic. CASA's really pave the way for children to find the best placement. You feel so good for doing this and it typically takes about ten hours per month, depending on your caseload, so it's a very do-able volunteer option.
