DH and I fought to get DD into an inner-London primary which had nearly 70% FSM, over 80% EAL and over 28% SEN. We moved out of London and DD now commutes in every day (over an hour on the train plus tube and a walk).
School is fantastic, DD has friends from all backgrounds/religions/races/socio-economic groups (parents range from unemployed single mothers who have serious problems to leading QCs to renown artists). I get on with all the other parents and haven't found any issues with parties and playdates - have been invited to some incredible parties in the African communities that are truly memorable for the amazing food let alone anything else.
The staff have high expectations both in behaviour and academically and the results are phenomenal.
Turned out DD is very dyslexic and the staff were the ones who spotted it, organised all the EP testing and a full programme with the SENCo, plus they make the effort to let her do some work in a way that doesn't involve writing from time to time.
Still can't quite believe that we are not paying through the nose for the quality of education that she gets and the amazing opportunities that they have for music, drama etc.
Often schools with a very disadvantaged intake can access programmes, funding and opportunities that the more MC schools can't.
Many of our friends looked horrified when they saw the stats on our choice of primary - now it's a case of local parents leaving the local indies if they manage to get a place.
So don't panic - see how it goes, and if you need to, you can always supplement at home.
