Thanks all. Yeah, no measurable goal at all. We do get a general report at the end of semester about what they worked on as a class, etc. SO, I asked DS today about taking him out of it for next year (after posting about it here) and he says he wants to stay in it. (eye roll) I guess there isn't any stigma with it or any negative self-image because of it! He also is excited that a kid he's friends with is joining the group next week. According to DS, this friend is joining because an older brother is in the group. The kid that is joining is excited to join b/c his brother is in it and my DS is in it.I have no idea what to think. LOL. I guess I should just be happy DS likes it. Still, I am worried about all the pull-outs! Well I'll be ready for next year and prepared with the advice from here to start the process of pulling him out if necessary.
So thanks!

And thanks for laying out the process for me step by step Polarbear! Very useful!
