Well, I'm a little overwhelmed. There certainly are plenty of questions. I suppose I'll just answer them more or less in order. First of all, I'll say that all these questions are very sensible ones, and all are ones that teachers should be ready and able to discuss with parents (and with each other!!)
First of all, Steiner education, like all education, has a creative aspect and an applied aspect. As a teacher, in planning my lesson I can try to find a unique way of bringing a subject for the particular group I'm about to teach. Or I can look up the curriculum plan for the day and use this. If the latter happened regularly it would be a "Steiner method" school; they would use the nice beeswax crayons and teach acoustics in sixth grade, as the method says to do, but there wouldn't be any real creative work going on (in an extreme situation). Most Steiner schools want to have people working from the source, that is, the source of Steiner education. To do that, in my experience, you have to have some deep connection to a spirituality compatible with anthroposophy. So part of the employment process is to check on this; they either ask about the applicant's spiritual path generally or about her/his connection to anthroposophy specifically. I think it's an acceptable question (i.e. sufficiently work related) as long as schools are open to a range of answers. One of our school's best and most long-standing teachers has no connection to anthroposophy, though she respects it; she is simply a very deep human being with a wonderful sense for how to enable children to learn. She is deeply respected at the school by everyone.
Hierarchies...At some schools there might well be a group who thinks they are better because of their anthroposophical background; I have never experienced this personally, however. The practical demands of teaching are pretty clear, and trump anything else - if you are competent and stable you get a lot of respect. A teacher at the Steiner school I worked at before my current school mocked all the Steiner-trained teachers (she had attended a normal teacher training); she thought they had weak practical skills. So there was a potential for a kind of reverse hierarchy there.
I'm sorry to hear that northernrefugee experienced a lack of compassion and humility, or even cruelty; this is intolerable in any school - in any social setting. Honestly: Steiner schools are not utopias. They have all the problems of any other school. There are insecure and intolerant people everywhere, and having an ideology to fall back on can intensify this. I do think that practicing any spiritual path helps many people overcome such tendencies - but it may intensify them in a few people, too. What can I say? I apologize for my colleagues if they've caused you distress. We've had a lot of intense work on social health at our school these last years, and it has helped our awareness of how to address issues such as bullying. This is another place where Steiner schools need to keep open to learning from what the society around is doing!
Any racial theory - by anyone - that claims that certain races are inferior or superior offends me deeply. Most anthroposophists, though, have only run into Steiner's statements about needing to overcome all prejudice (gender, race, etc.) and the need for all peoples to work together - that all together are important for the whole of humanity, each having special gifts to bring. You have to realize that this is what you find in his most well-known writings; the weird comments (of which there are, alas, plenty) are mostly in works that your average teacher, or even dedicated anthroposophist, either has never read or maybe has read once many years ago. So people are partly just not aware of these, and partly a little in denial; if someone brings this up, the first reaction is going to be - "there's no way Steiner said something like that" - because it seems so opposed to Steiner's thinking, or at least to most people's ideas about this. The second reaction, once the person is convinced that he really did, is that it is irrelevant; "just ignore this, it has nothing to do with anthroposophy". On one level, this is kind of a good answer - it means that anthroposophists believe that racial prejudice really does have nothing to do with anthroposophy, and since the latter is formed by real people in the world today, it is a self-fulfilling expectation. On another level, it totally ignores the fact that Steiner was able to make such comments.
My personal take? For Germany at that era, he exhibited a fairly typical mix of idealism and racial stereotyping. I take the latter as something we all want to put behind us as fast as possible and check out the more worthwhile sides. Remember, though, I get to cherry-pick, as I'm not an anything-ist!
The question of how to address parents about the nature of Steiner education and anthroposophy is really good. We all find parent education a real challenge. It's perfectly possible to bore a group or individual totally, or convince them that you are unhealthily single-minded, by going on and on about anthroposophical ideas when they just want to hear about the education itself. On the other hand, it's perfectly possible for a parent to feel that s/he was not adequately informed. Most people I've talked to about this have had more direct experiences with the former situation; many parents simply have a limited interest in hearing about spirituality, reincarnation, Lucifer and Ahriman (anthropomorphized yin and yang principles, more or less), or whatever.
In our training we were advised to be sensitive to what parents actually want to know. It's my impression that now many or most schools are increasingly careful to ensure that parents understand that there is a spiritual background to the education; our school is extremely public about this. And I agree that this sort of "disclosure" is important; people should understand what they are getting into.
If the question about being compelled or invited to study groups applied to the trainings, I suppose that there's little choice there (study of books by Steiner are frequently part of the course). In schools, however, there are no compulsory anthroposophical study groups, at least that I've ever heard of (and it seems a pretty unlikely idea). But in faculty meetings teachers might well study a book by Steiner on education. Does this count? The intention is to explore pedagogical questions.
Personally, I found that my Steiner teacher training deeply respected my and others' own spiritual paths; teachers and students showed genuine interest in my Quaker experiences, for example.
I'm running out of steam fast, friends. Olympic games? Yes, our school takes part in these; the children of various schools join together in mixed teams to "compete".
Sorry for the length of this missive...you asked so many questions!!!
Best wishes!
