There is a certain skew to the views on here... (which might be correct, or could be incorrect!)
In theory, being an academy opens up the options for a school - gives it more autonomy, more flexibility in meeting high standards etc. Where it is working, it works very well - there are even independent schools that have moved into the state system and become academies... There are plenty of examples where academies have transformed failing schools...
on the other hand - there are equally examples of where it might have been a negative move - with schools being run more commercially - less for the children (as some of the above comments observe)
LEA control is not necessarily a good thing - it can be very controlling and restrictive... In 15 years of being a governor across all sectors (CofE / LEA / Academy / independent / boarding / day / junior / senior) I am yet to see the LEA work efficiently - good people in the LEA are fantastic - the majority sadly are not...
Ultimately:
- school with good management and governance will usually flourish as an academy
- school with weak management and governance / a controlling company with different priorities - may lose the balancing role of the LEA and suffer
LEA control brings schools to a norm - it may raise the lower schools, but it certainly brings down the better schools - Academy status gives a lot more freedom, freedom to fail or fly
If the government can recognise that and use Ofsted (or something else) as a balance on the schools who move downwards, then it could be a very constructive approach (freedom to excel, but support not to fail) - if that doesn't happen then the likelihood will be a bigger disparity between the best and worst of schools - at the top end they will challenge the best of the independent sector (as is already happening), at the bottom end - well you might not want your children to go there!
As for teachers and qualifications - same pattern, it will allow the good schools to add value - by bringing in those from other industries and sectors to add to a child's enrichment - maybe to use organisations such as Teach First to bring in highly capable people and train them on the job etc. - in poor schools it may be used as an excuse to bring in people who really shouldn't be there... Bear in mind that a school such as Eton which provides a fantastically high-level academic curriculum doesn't have to employ just qualified teachers - the independent sector has been free from that for years - and having trained for 4 years as a teacher, and then spent 20 years since in business, I am convinced that a teaching qualification on its own doesn't make someone a good teacher...
Ultimately many people in this country would like the quality of independent / private education, but not to have to pay for it - Academies if done correctly can give exactly this - it is not the concept of becoming academies that is concerning - it is whether the checks and balances are in place - and that is an issue for all forms of state education...
