@Undecidedthiswinter Firstly - being a governor requires very little “business strategy”. Unless it’s a private school of course. What a governor does has little to do with business. The finance committee is the nearest you will get and you will find the vast majority of the budget is staffing costs. Over which Governor has no say. You are there for strategic decisions, not operation of the school.
Some governors posting here are a bit out of date. The critical friend label went out about 10 years ago. It’s a board of governors recruited for their skills. It should not be a random group of people. If it’s a good governing body, they should identify the skill profile they actually would like. This might be finance but could be Sen for example.
The role of a governor carries a training commitment. Therefore you need to know about legislation but also data interpretation (school improvement and dc progress) , Ofsted inspections, school budgets, appointing SLT, etc etc. The main thing for governors is to ensure the improvement plan is having an effect by monitoring data and evidence. The governors should not just accept what they are told.
Most schools meet as a full GB once a term but the committees will be more often. However, you are not operationally running the school. The head is.
If a parent governor knows a dc who is permanently excluded, they should not sit on any PX committee. The members of this should be flexible for this reason.
Expect to see a termly very detailed heads report and you will monitor by making visits. So expect some reading but it’s not 20 hours a week. (Go and do training to get up to speed! Learn from experts). That’s a governor trying to run the school. Neither should you be roped into fund raising or baking cakes or listening to reading. Your role is strategic. It’s not an extra pair of hands.
