It is going to take years and much more money raised promised from vat on schools to fix the mess that the education sector is in.
The education sector is connected closely with the social services, police and the economy.. When one part of the chain is broken, everything else is broken. In our case everything in this chain is broken. The VAT on schools is only going to put a small patch on the problem. I already know few people who have jumped ship to state high schools because of the VAT increase next year. It has started to happen.
