The snow goose need not bathe to make itself white. Neither need you do anything but be yourself.
No two teachers will go through an inspection in the same way, but there will be certain features of the experience that are typically shared. Keep this in mind as you talk to colleagues when inspectors arrive at your school. It would be impossible to predict exactly what it will be like for you to experience an inspection but the following questions from teachers who have faced inspection before, and their associated answers, will help to show what might be a part of your experience. Above all else, view the experience of inspection from a position of empowerment; there’s a lot that you can influence by your attitude and general approach and that influence isn’t to be under-rated.
