Both my children went through Ashmount.
My youngest is in their second year at Secondary School now. They both had a positive experience, although the school has actually improved since then. So as far as I can tell its moved from being OK with good bits, to being better than that.
For example:-
When my daughter was there it was a three form entry school ie took in 90 children a year. While my son was there it went down to two form entry which is a much nicer size in my view.
The experience a child has depends on the children they are with and their teachers. When my daughter was there most teachers were very good but there were a couple I wasnt so sure about. By the time my son finished all those "doubtful" ones had left, "encouraged" as far as I can tell by a new Head, Pana McGee, who came well recommended from Martin's School in Barnet.
Another thing about the school was its ethnic diversity - a huge range of ethnic origins, and that has stood my children in good stead.
I must say hat I only became aware that the school was not always rated as "desirable" by middle class mums after my daughter had been there a couple of years. And surprise was expressed that I did not have her in one of a couple of other schools, one of which was a church school. However both my children have ended up at secondary school with children who went to the other "desirable schools " It doesnt seem to have made any difference.
Health Warning
My experience as a parent ended two years ago so I really, really, would recommend that you go and see Ashmount for yourself.
