@Araminta1003 I am very happy with my DCs schools and all are now academies! We do not have big problems and if parents do not like it, they can vote with their feet and pull their kids out and send them to another school.
If you mean that parents can move their kids to non-academies, no, most families cannot do that. Most state secondary schools are academies. There are many parts of the country where the percentage ranges from 80 to 100%.
Regardless, I am not sure that "I have never had a problem myself, so those who did can get lost" is a reasonable or fair approach.
They are accountable to parents, parental opinion locally matters hugely. Parents, en masse, being dissatisfied is terrible news for schools so most do care.
How are they accountable, exactly? They are not. They are only accountable very indirectly, to the extent that, if a school becomes undersubscribed, it loses funding. But there are many parts of the country where the demographics are such that most schools are oversubscribed and will continue to remain so.
Are you familiar with what's happened at Holland Park school and Mossbourne?
Both rated outstanding. Both oversubscribed. Both had excellent results on paper. But, under the surface, both enabled a climate of fear, bullying and emotional abuse

Creating a hostile climate towards special needs children is one way to achieve this, but not the only one. Those two schools have done much worse.
Are all academies like this? Of course not.
But the academy model means that academies mark their own homework. They investigate their own complaints. Not even the Education secretary can overturn an academy's decision (look up their complaints policy).
Take Mossbourne: hundreds of people come forward with accusations of bullying and emotional abuse, of seminars on how to instil fear in children, etc. And what happens? Nothing. The school commissioned its own investigation (the suspect paying someone else to investigate it!!!), whose results will not even be disclosed.
Are you happy that your tax money is being used this way? I am most certainly not.
Would you accept a system where, if you complain to your GP, the GP investigates the complaint, and no external authority or body could tell the GP practice they were wrong???
