In the course of achieving a Masters in Education I studied Waldorf and its founder Steiner. My impression was  that there was a very loose connection between his "occult" practices and curriculum. Since Christian values are the root of our culture, one could just as easily say mainstream public schools operate under embedded religious values derived from principles handed down 2000 years ago in a book that contains the mystical words of a deity. 
It IS good for all parents to know the underlying philosophy of the school their child attends. The parents at Waldorf school have made a decision that the actual activities of a Waldorf education fit with the goals for their child. For those who believe in local control, Waldorf, like charter schools and religious based schools, are as local as one can get.
