Lisa, I agree that a college's quality and reputation is about more than its facilities. That said, I used to work in education before I retired. The last college I worked at (not in this area) moved into completely new buildings while I was there. It was a transformation. Student applications shot up, staff and student morale improved, the quality of teaching improved because good staff wanted to come and work there. It made a huge difference, and I have no doubt that it will be the same at camsfc if this scheme goes ahead.
Re becoming a governor, if my experience is anything to go by, the camsfc governors will have something like a 'search committee' whose job it is to identify suitable new governors, and ensure that the governing body keeps an appropriate balance of expertise in its membership. There's nothing to stop anyone writing to the clerk to governors and offering their services, but it's a long-term process, involving succession planning for when existing governors reach the end of their term of office, so don't expect anything to happen quickly.
