I work in lots of schools – paid for by parents – and have never had any issues. Schools are generally very grateful. However, I have had one school recently that were absolutely adamant that I could not see children there – despite the fact that there were three separate families wanting to pay for me to see their child. The headteacher really dug her heels in and said it was not appropriate as the service was being commissioned by the parents. I found this very bizarre. The parents complained to no avail.
