We did it. We withdrew our son from school on Friday. He is ecstatic. My husband and I are cautiously excited (we're both Virgos,) and figure the worst that can happen is having to get on the waiting list to get back into the charter school. (We decided it was worth the drive if necessary.) We purchased the requisite copy of What Your Fifth Grader Needs To Know, and a couple of teachers from his charter school gave us the list of books they will be using this year as well as a review book for 'The Test.' You know, in case we get the urge to download it at the end of the schoolyear... We also talked to his chess club sponsor who suggested we continue to come to the tournaments. She said we could still sit with them even if we were our own 'team.'
Thanks again to everyone who posted a comment with suggestions and support.
