Our 6 yo DS has recently been diagnosed as autistic. We have been advised to change school. We’re looking for a calm, nurturing prep school with lots of green space and classes of c.14 pupils. DS2 is 4 and so far is neurotypical. We would want him to go to the same school. We have looked at a variety of prep schools in the south east within a commute of London, including Hazelwood in Oxted and Kingswood School in Epsom. What other schools should we consider? Grateful for all advice!
