My DCs started formal instruction at 6ish in the US. They went to various classes from age 4. DD1 went four afternoons a week in a RC school, DS went to classes three mornings a week in the local YMCA and the other three DDs went to a different RC school three mornings a week at age 4. At age 5 they all went to kindergarten in the second RC school. This was 'half day' kindergarten, five days a week. Two and a half hours a day.
There was a lot of play. Play included hands-on science, cooking, craft and maths activities (no pencil and paper exercises), and there was story time, circle time, discussion of weather and season, trips to the local park, snack time, bathroom time, time allowed for taking off coats and boots unaided in the morning (no parents allowed into the school) and dressing again at home time (no parents allowed inside). Self care was really focused on, as well as care of the environment and shared materials, and school etiquette (talking in turn, consideration for others, quiet when the teacher made the quiet sign). There was no formal instruction and importantly no testing. It was assumed each child had his or her own developmental stage, academically speaking, and having everyone in the same room held to the same academic standard was an idea that didn't occur to their teachers. Wrt self care otoh, all of the children were expected to do for themselves, including buttoning, zipping, putting on mittens, wiping themselves in the bathroom. In Kindergarten they were expected to master tying shoelaces.
The DCs were all reading by the time they emerged from kdg. Two of the girls were reading just before age 4, so before they ever set foot in school. I read to them a lot at home. They were taught formal phonics in First Grade (age 6 to 7), which was their first year of full day-all week long school (8am to 3pm)
I would never, ever consider Steiner school for a child of mine. Steiner-Waldorf education is a cult. Parents get sucked in by the artsy fartsyness and the natural materials and the carefully designed simplicity of the environment. They are not told about eurythmy or the idea that their children are held to be incarnating themselves (Hindu stylee) or that the school curriculum is designed with karmic incarnation in mind first and foremost (this affects what is taught as 'history') and therefore there will not be any attempt made to intervene if behaviour issues arise, your child's or anyone else's child's. Your child could be in a class with a domineering little madam and suffering all sorts of problems but the individual journey must not be interfered with -- your child has her journey to undertake and the bossy brat has hers.
They are not told that their children's artwork will be carefully scrutinised and that it is possible for a child to get art 'wrong' this happened to DD2 at a watercolour class I got her into that was run by a Steiner teacher, when she was 3 and asking to go to big girl school. I thought an afternoon of watercolour painting couldn't do her any harm. How wrong I was. DD2 even at that age realised there was something wrong with her dreamy watercolours though the teacher never said anything to her. I later uncovered her fault her paintings lacked any semblance of the shape she was supposed to reproduce on her naturally sourced, rounded cornered, expensive watercolour paper. They were 'just' dreamy whirls of colour. I loved them. Not telling people what the expectations are, and then making it clear that a child is falling short of those unstated expectations but still keeping the exact nature of the expectations secret is part of the MO of Steiner educators. Most sensitive and intelligent children respond to this type of exposure to the esoteric by trying harder and becoming disheartened and bewildered by the lack of approval.
Thank you for that link, MaizieD.
One of the companies mentioned as an offshoot of anthroposophy, Weleda, had links to the farming/kitchen garden operations at Auschwitz, Dachau, Ravensbruck and other places. The land, wholesomeness of nature, and farming, etc., was one of Himmler's pet projects.
