Thanks - as it was a first tour there was n shadowing but I understand this can be arranged as necessary. Dd5 refused to visit it he was sick so he stayed home.
At the moment his class is play based so he gets a lot of one on one attention but 2nd term in and he has already completed the curriculum. They can push him ahead ( which they did with dd) but will run into problems with the format of the class. I agree that it will benefit both.
