"Which is why I don't understand the point of the Free School programme"
MumTryingHerBest, every Government has its own programmes for creating/expanding/improving schools, some more experimental than others, and some more successful than others. Optimistically I like to think that lessons are learnt along the way, and the best of past schemes is incorporated into future ones, so that things improve over the long term.
The Coalition Government's Academies Programme (of which the Free School programme is a part) is an evolution of the previous Labour Government's Academies programme. Some would say it's an evolution too far.
If Labour get in next year, they will symbolically "scrap" the Free School programme, and rescind some of the freedoms of academies, but academies will still continue, and Parent-Led Academies will be the new Free Schools.
In other words, they will reign in the Free School programme, and re-name it, but keep those elements of it that they consider have worked well.
I do think that the education system tends to improve over time as a result of all this innovation and experimentation. It's a bit like the stock market though, with lots of ups and downs along the way!
