Not sure at all about some of the comments on here - our daughter is at a Steiner School and loves every minute of it.
Never ever heard any issues about non-acceptance of special needs - indeed at our last Steiner school there were several children with very special needs, that were amply catered for.
In many cases, children transfer into Steiner out of mainstream because of problems encounted by non-acceptance.
Learing to read - many children who are Steiner educated do learn to read before 7 - reading is not taught as such before then but no child would ever be discouraged from learning to read.
Don't forget, it is only in the UK that we have this immense pressure on children to learn to read at such an early age - 6 or 7 is the norm in Europe, America, Australia etc.
Steiner children, as a rule, do learn to read very quicky when they are ready - and this is a key element - by waiting, they are very receptive to learning to read when the formal lessons start.
As with any school, you must go and meet the teachers and other parents and talk to them before making up your own mind.
You will find that there are lots of differences to mainstream schools - a strong discouragement of TV, video games etc, a big emphasis on co-operative play, huge amounts of time spent outside, gardening, on craft projects, a wonderful appreciation of colour and nature and the development of the creative and imaginative side to children rather than forcing them to learn at a pace dictated by "well meaning" MPs who create usless targets as they are desperate to show that they take education seriously.
Like anything "different" Steiner education does have its detractors amongst those who don't understand or are scared of something out of the ordinary - best advice is to go and have a look and meet some of the children who are there and see what you think.
