Actually @vikingmum the official rationale for Free Schools is to provide parents with choice which is why the DfE can, and have, justified opening Free Schools in areas where opening the Free School creates a surplus of places. The Judith Kerr School because of its special (bi lingual) nature obviously does provide a different kind of schooling to that of the other primary schools around it. So if you live near enough to it, you have a choice.
However on top of this policy local authorities, who still have the legal duty to make sure there are enough places, are not allowed to open schools anymore, they have to be a Free School.
So the two issues this raises are:
1.Where money limited, and there are areas short of places, should not the money be concentrated there rather than used to create additional choice where places do exist?
2.Although politicians of all stripes TALK about parental choice, it does not exist. Parents get to express a preference not make a choice. For people to have a choice there would need to be a lot of vacant places, but no politician is prepared to pay for these....
