Steiner schools are not independent of each other any more than Catholic schools are, and they do not all have different approaches to bullying or any other issue that comes up, depending on the character of the governing board, etc..
Steiner schools all have as their fundamental, core identity the bedrock of anthrosophy, which involves belief in incarnation and the karmic process. This informs every single element present in every single Steiner school, and every approach to every issue that arises. Rudolph Steiner was in fact a guru, and his teaching remains central to everything that is done in Steiner schools and every element of the environment.
There is no religious teaching per se but every element is informed by the religion of anthrosophy. The environment is unstructured as Unescorted reports, and not just when it comes to time management. Bullying when it comes up is left to the students to 'resolve' amongst themselves as they incarnate. If a student doesn't encounter bullying it is purely down to luck. Attainment targets are not a feature of Steiner schools because their primary aim is not academic but spiritual - the development of the soul. Academic aims and those who are concerned with them are rather looked down upon, as the phrase 'hung up on spelling and facts and figures' illustrates. Rudolph Steiner was not interested in empirical science, but in what he called 'spiritual science', which he considered to be a higher plane of knowledge, and necessary for the central process of incarnation and spiritual development. That belief informs the curriculum. It also informs the curriculum as it relates to children with SE, who are held to have somehow wished for their SN in a former life. Steiner methods seek to ensure they have a 'higher' level of existence in future lives.
In the words of Rudolph Steiner himself, Anthroposophy is “spiritual advancement through karma and reincarnation, supplemented by the access to esoteric knowledge available to a privileged few.” So perhaps it is not surprising that even someone who is a governor of a Steiner school would be out of the loop. Steiner education tends to hide much of what is really significant about it, what makes it truly radically different from all other educational philosophies (Montessori for instance), from the public. It hides behind phrases such as 'individual child's development' that mean all things to all people, and brochures and tours are designed to allow parents to project whatever wishes they have for their child onto the school they visit. The Anthroposophical foundation is kept tucked away.
Eurhythmy (what Siri calls 'movement based practice to help co-ordinate and balance the body') is innately connected to the notion of karma, and the process of incarnation. It is used in Anthroposophic medicine for therapeutic purposes therapeutic in the sense of being an aid to spiritual development and in schools for the same purpose. In schools, eurhythmy is used to help move students through the different phases of their spiritual incarnation and to deal with issues of development such as rebelliousness towards authority. In Steiner schools, the first Anthrosophical stage that is incarnated is the etheric, at about age seven, when milk teeth are shed and the adult teeth appear -- this is the signal to begin teaching reading. This is followed at age fourteen with the onset of puberty by the appearance of the astral body. At this point reasoning is introduced into the curriculum. At about age 21 the divine selfhood incarnates.
Siri's choice of words is interesting because co-ordinating and balancing of the body is sort of like saying eurhythmy seeks to improve balance and co-ordination, which could just as easily be achieved by ballet or gymnastics after all. But eurhythmy is a specifically designed 'practice' requiring specially trainer practitioners, and it has a spiritual end. What is being co-ordinated and balanced is actually spiritual elements in the body, which according to Anthroposophy is really only a vessel for spirits. Eurhythmy facilitates the spiritual midwifery that Steiner schools seek to accomplish.
And now we see the usual appearance of the phrase 'the anti brigade' which is par for the course for all threads on Steiner education. People who ask questions are not in fact welcome on Steiner threads; despite what Siri says 'The danger of any philosophy is when it leads people without question,' questioning of Steiner education is not welcome by those enmeshed in it.
