Anybody here familiar with the Court Appointed Special Advocate (CASA) program?

In investigating volunteer programs, I found out about this particular one. CASA volunteers are responsible for looking out for the interests of children in court cases involving neglect or abuse. They are responsible for seeing that children are properly placed under foster care or are returned to their parents. Here is their Web site.

My initial reaction is to wonder how such jobs could be left for volunteers. I do not feel qualified to take such a position and I give great credit to those who do. Have you worked in this program or know of anyone who does? I would be curious to know anything about how well it operates.
