It is is for confidentiality reasons that you cannot know individuals. You do not need to know individuals, your role is not analysing data. You do not need to know names to ask questions about data, performance, attendance,behaviour etc. Governors do not 'do' things, they ask questions of others. I have known an incident where governors have 'guessed' the name of a child being discussed (as we are a small school) and 'gossiped' about them on the playground to other parents. That is breaking the governors code of conduct and could lead to removal from the governing board. If you want to do the things you suggest you need a find a paid job in a school as a bursar or something. It seems that being a governor is not what you thought it was. Being a headteacher is not what I thought it was. Sometimes governors can be really obstructive but I expect they don't mean to be.
