One of the big issues around academies is lack of accountability. Until recently, academies were accountable to the DfE but this didn't work because they were so many of them. Now there are 8 regional commissioners who are responsible for oversight of academies. By the figures on the BBC website about current numbers of academies, I reckon each regional commissioner has oversight for approximately 565 schools.
My local catchment school is shit. 39% A* to Cs in one of the most affluent areas in one of the most towns in England. It's been OFSTED requires improvement for as long as anyone can remember. It been part of a multi-academy trust for the past 10 years. Has the Regional Commissioner done anything about this? No. He hasn't. Because he has 655 other schools to look after so, you know, he's a bit distracted.
Some MATs have done away with governing bodies for individual schools, removing local accountability but also local knowledge of what particular communities know to be important. One of the key roles of boards is to engage with stakeholders.
From what I can see, many schools sign up to be part of MATs without being totally clear what powers they are signing away. In MATs there are usually two tiers of governance - the board of the MAT trust and the school governing body. In many MATs, the MAT trust board has the power to decide what powers to delegate to schools and what to keep for themselves. So, for example, a school might initially sign up to by part of a MAT and retain the power to for their school's governing body to set their own admissions criteria or pay and conditions for teachers. However, if the MAT trust board decides they want to centralise policies, they can impose new admissions or pay policies onto individual schools within the MAT and there is absolutely nothing school governing bodies can do about it.
It's simply not viable for most primary schools to be standalone academies because they are too small to make it work. They will therefore have to join in MATs with other schools. I predict a huge amount of time and effort put towards trying to establish a pecking order, time that frankly could be better spent focusing on raising the quality of teaching and learning.
