They seem to be in independent schools - a sort of consultancy practice?
What sort of things do they do? Is it fees, building projects, workload?
Do they advise parents and staff, too?
Sorry if I am being a bit naive. I know that they have come into my own school in the past, but I am unclear about how / why we would be using them and who benefits. Has anyone had any experience? (Is it to do with pensions?)
