Ofsted stands for the Office of Standards in Education. They are a team of inspectors who arrive at your school with only 48 hours maximum notice and can walk into any classroom and grade your teaching having been there for 25 minutes, ask for any documents and can grill you on your own or in a group for as long as they want. They will walk round a school, talk to children, staff, parents and governors and, in less than 48 hours, will decide on whether your school is poor and should go into special measures, satisfactory, good or excellent. They will also decide, after seeing you teach for 25 minutes, if you are a good, poor or satisfactory teacher and if your department is good, satisfactory or poor. Basically, they have the power to put a school in special measures, or hold it up as excellent, make or break a teachers career and walk away with no comeback or right of appeal. And we aren't meant to be worried....
