I called because i needed help getting my son assessed, we already had an appointment but i couldnt get the school district to do the assement because they didnt think it was worth it. I told all this to the advocacy center they gave me a number to call and told me to let them know if i needed help making an appointment. I tried to explain that i dont need help with making the appointment but with what goes on during and never heard back..so now im back at square one doing this by myself.
