I did send an email first to the teacher. And she responded in a nice way, saying she understood my concerns and let's meet next week but that he made 3 mistakes on the pre-test for that unit. She cc'd her response to the principal, bringing him into the conversation. Also, at the end of last year I had concerns that my DS wasn't being challenged (he wasn't selected to go to this pull-out in the second half of the year for LA enrichment, though he loved it the one time he was pulled out, and the teacher who ran it said how enthusiastic he was) so I met with the principal, so I felt we had some kind of relationship established since we discussed DS' needs and he said that it was important, for DS' motivation to learn, to be with like-minded kids this year......
