Keep your sense of humour. Laugh every day - in their hearing, if possible. I'm Primary Special, so can't add a lot from personal experience curriculum-wise. Look after yourself. Put in mega-bribes for the kids, if you use rewards. They know what's going on. Treat Inspectors as you would a (slightly unwelcome?) aunt coming to tea - best bib+tucker, best behaviour in front of them. Don't relax anywhere, anytime, even the loo. Have a "secret place" in school where you can go for a confab when they are having theirs. If an Inspector asks about something in the department one day, make sure to inform whoever is observed the next so they can dish it up. Cynical? You bet! And I'll be asking for favours returned when we get the dreaded brown envelope!
