Taurisk I have known a number of children who went to a Steiner school and they certainly have seemed quite normal to me. But it is their philosophy, in the early years, to let the children learn at a lower pace. Those children who did not stay the course at a Steiner school found the transition to a public school rather difficult.
Overall most comments that I have heard about Stenier schools have been positive, but it is not for everyone.
