I would be real clear on the purpose of the mtg. I know some folks who they mtgs went poorly and it did mess things up. In part in one case because the a question was asked about going to class with big kids vs friends. of course this upset the kid. I just personally wouldn't want to be in a position of talking about decision in front of my child. we are the adults. i think at their ages - at this point - it is our job to figure this stuff out. if the point is to get a feel for the kid a typically screening... well it is what they want to do i just hope the principle's intent is a friendly meet and greet.

like dottie and mon i've save any decision making conversations for another time... you can use your child as an excuse - maybe you have a few more questions to address on the phone or email privately.
