If anyone can answer this query, or point me in a direction to find an answer it would be very much appreciated. If an Ofsted inspector does a joint observation with a headteacher, do they have to check and inform the teacher before hand? We had Ofsted a while a go, and we had unannounced observations. After this I was informed by another teacher that this isn't allowed without prior warning. We have just had Ofsted again, and this time I had a joint observation without warning. Is this allowed? I would certainly like to question why we weren't informed if we should have been, but don't want to shout my frustrations if it is allowed. Does anyone have any opinions on this? I have no objections in principle, two minds are better than one, just the way it was handled in our school.
