I would also caution that Waldorf schools aren't philosophically neutral, so parents should be aware of the anthroposophy ideology that underlies the Waldorf method.

I agree with ultramarina that this philosophy could be quite damaging for young gifted children. Anthroposophy ideology is based on a form of karmic reincarnation and could falsely ascribe friction between students and school administrators' rigid practices to being the child's due from "another life". Particularly for a vulnerable child, I would steer clear of Waldorf teaching.
