err Evil Twin does not appear to understand what school governing bodies do, and how they do it.
if the GB he has had experience of has been disolved due to special measures it seems likely that it did not understand its role either.
A GB is a collective body. It consists of a number of Governors. Some are elected by teachers at the school. Some are elected by parents. Some are appointed by the LEA. Some are coopted. The Head is also a Governor.
Thus a range of expertise is represented on the GB.
A GB full of education experts would NOT be a good GB.
Schools are neither run by parents, nor teachers, nor the LEA but by all working together. The GB is a strategic body
not concerned with the day to day running of the school.
That is why you do not need to be an expert on education to be a governor, but all GB's do need to have some Governor's with expertise.
I am not a school teacher; I have no training in education, but I would take it very amiss if a teacher on our GB was to tell me that my professional background in Organisational Psychology and Management, my work in project management and consumer advocacy, and my experience of having been a parent at the school (my children have moved on) was not relevant to the GB.
What is needed is a variety of Governors.
Finally, as the role time consuming and unpaid it is reasonable to suggest that it can be, and for me has been, very rewarding.
