I'm a primary school governor. I was a teacher for all of my career and have taught primary and secondary, been an advisory teacher, class teacher, SLT, managed a team of 25 over the years.
I think people with experience in education are vital because of the experience they've had, but I also think schools need governors with other business experiences, particularly finance are very useful.
I've been a governor for a couple of terms, have been on lots of courses, done training, attended in service days, am on working parties, sub committees and a variety of meetings in school. I haven't been to all the school events, but think that is less necessary that being part of the process that influences the strategic development of the school.
I've always been welcomed, but there is an underlying feeling sometimes of people being wary. I believe the role should be always strategic, but the divisions can sometimes be blurred and there is the potential for clashed between the operational and strategic.
I am in school at least twice a week, but haven't been involved in a learning walk. I can see how someone with no experience of teaching could be irritating to a teacher, but I've done learning walks and observations as a teacher and been observed of course, as well.
