What change of schedule? There should be no changes when Ofsted comes in.
We have just had Ofsted in. They completely dictated the timetable for the two days they were in and there was a lot of schedule changes! They wanted to see one year group teach history on the first afternoon as that was a Deep Dive subject-this was a change to the schedule. They also wanted the history coordinator to talk to them at 2pm, then take them on a learning walk around the school. This meant that teacher’s class was covered by a random TA who they’d never had before, doing a subject they normally did at a completely different time. This was repeated across other subjects. They also wanted to see/hear handpicked (by them) children read at a specific time when they should have been in maths. They wanted eg a Y1 PP, Y2 EHCP, Y3 K, Y4 high ability etc.
Ofsted do not just appear and see what is going on-they completely shape what they want to happen. This can be hugely dysregulating for some children.
I’m not saying it’s a good thing for pupils with SEND to be told to stay at home, but saying that there is no change to the normal schedule simply isn’t true in my experience.
