It is quite astonishing that you can come to the conclusion that there is a loose connection between Steiner's occult beliefs and their curriculum. Every aspect of the curriculum, from topics, to form to timing, is driven by Steiner's occult writings. All Waldorf Schools practice Eurythmy - Steiner's mystical dance that uses style to express spiritual meaning and therapeutic intent. There is no other rationale for Eurythmy that Steiner's religious beliefs. Similarly, the art - each colour has occult meaning. The pastels and watercolour have spiritual significance. The topics in class from the pseudo-history and myths to the study of particular animals are all driven by his writing. The festivals celebrated are Anthroposophical along with the 'verses' said every morning are actually Anthroposophical prayers. 

Steiner said, "Never call the verse a "prayer" but a "school opening verse"...This will go a long way towards overcoming the prejudice that this is an anthroposophical school."
