I take your point ymb.
My personal view was that i was passionately interested in the local schools when my kids were attending.
Now they're not I really don't care.
Parents who have a commitment beyond that remind me of that saying about anyone who thinks they should be President shouldn't be let near the job.
The only 'choice' most parents want is a local school with high standards; too bad if your local is some sort of 'Academy' specialising in The Arts or Sport if your kid wants to specialise in science - or vice versa.
In some areas, the local school is good, but Sikh. I have nothing against the Sikhs but in 2014 that is just bonkers.
As you say, firm regulation on what should and should not be done/taught in the school, and not subsidised at the expense of the state schools.
