I think in the past few years we seem to have put so much pressure in mainstream schools for children to be up to a set level when they are so young. Alot of countries where they don't teach 'formal' education til the children are older seem to to very very well.
I find it very interesting to look at the results on the Myschool website for the Noosa Pengari Steiner School, Across the board at Year 3 they are substantially below average but in the later years they are above or substantially above in most areas. I'm guessing this is because they leave the 'formal' stuff til the kids are older.
Mmmmm food for thought.
