I don't understand why people have a problem with them (but hten, as I said, I actively sought out, and was incredibly grateful when I found, an alternative school for dd1).
some people don't like how state schools are run (various different factors).
they might choose to take a chance on a free school - no one is forcing them to, and if they are wise they will ask a LOT of questions about expectations, ethos, curriculum, etc.
other people think 'what a load of nonsense, the local school is just fine' and so apply there.
everyone is happy.
I really don't get the unease, or cynicism.
even if the schools manage to turn a nice little profit - well good on them (as long as all educational criteria have been met, and they aren't feeding the children dry crusts and plain water, obv).
dd1 went to a school with 3 pupils. it was exactly what she needed, at that point in her life. I know plenty of people who thought we were bonkers, but then I would have thought them bonkers if they, in our position, had not done what we did.
takes all sorts, doesn't it?
