Non-selective independent schools in SE London

[Mummysaysno]

Very grateful for suggestions for non-selective independent schools in SE London. Essentially a school welcoming to a Year 3 ADD child possibly also with Dyspraxia. Not interested in going through the usual hothouse 7+ for DS, as he will really struggle.
Willing to drive around 45 minutes to school, with Dulwich being our home. We have time to get him on a wait list as we won't be returning to UK till Sep 2014.
Thanks!!

Hi, my 14 years old DS is high functioning autistic. He’s in mainstream secondary, doing ok academically, but no very happy there. I’m looking for recommendations for SE london private and state school where he could potentially move. Thanks!
