Still catching up on all the replies, but just got off a call with the principal. I don't have all the details, but he said they spoke with the teacher and interviewed the boys in the class individually (not sure whether it was some or all of them) and were shocked to hear what has been going on with this child. He stated that this student is extremely troubled and very much in need of help, and that while this is a very sad situation, this school is not the appropriate place for him to get that help. Today is his last day at the school. Again, he did not provide all the details of what he learned, but made it very apparent that it was extremely disturbing and that while the conversation will be difficult, the decision was an easy one. He stated that his primary responsibility as a school administrator was to ensure the safety of their students and that based on what he has learned, he must be asked to leave. I feel bad for the kid, and his mom. But my child's safety is paramount, and given the tenor of my conversation with the principal, I feel even more strongly that the right decision has been made. By the way, he confirmed that he had not been made aware of any of the things that have been going on with this student, and expressed disappointment that he had to hear about it first from a parent.
