I'm currently finishing off an application for a school I have worked in on supply. The school invited me to apply for the position, so I am very keen to impress. I have written a very comprehensive personal statement but it is 4 pages long. Should I shorten it? I have included lots of examples to show how I meet the person spec, and I am loathe to take these out, but I don't want to put them off with an overly long personal statement. I usually write about 2 pages for a personal statement - what length should it be?
