Yes, my child attends thet TAG center schools aftercare program.
What you were told makes no sense to me whatsoever. You should contact the BAS-ELP office

Now, on the registration packet there is a comment that the BAS ELP is for kids at the local school as part of their attendance area. However, if your child is in the TAG program center for his or her address, that IS the TAG school for her attendance area.
