"My concern is with the lack of openness ("transparency" if you like) ..."
daphnedill, as I said before, I think reasonable answers can be expected to reasonable questions. However, you also need to treat people as innocent until proven guilty.
If your children's school's governors didn't have their profiles published on the internet, or the LA officers who ran your local education system for that matter, would you bombard them with requests for their CV, and write a blog about how their lack of response must mean they have something to hide? Would you proclaim that the fact you don't know exactly which schools they've worked at previously must mean that they have no experience to do the role? No, you'd assume that the people who appointed them had adequately checked their background, unless you had some specific reason to doubt it.
Perhaps what you're missing here is the fact that the free school approval process does include rigorous checks of capacity, capability and suitability. I'm not saying the DfE always get it right - there have obviously been some high profile mistakes on that front - but that doesn't mean that all free school trustees should be viewed with suspicion until you have personally vetted them. I'm sure there have been some dodgy goings-on at LA-run schools in the past, but the vast majority of those are left to get on with things without too much finger-pointing.
I'm happy to answer your questions, because I think it's important to set the record straight. However I can also understand why others have ended up closing the door on groups that have taken up a considerable amount of their time with questions that would more appropriately be directed at the DfE. After all, groups are simply trying to work within the framework that the DfE sets out; a framework that is constantly evolving. Sometimes it evolves in response to feedback from the groups themselves, because they don't always see things working properly either. I think everybody just wants education policy to be as free from politics as possible, to be able to get on with creating great schools and not be bogged down by nasty accusations from people who either don't understand, or don't like, the latest policy initiative.
