How many people plan for potential Ofsted lesson observations in advance? There are some LOs that I would particularly like to cover when being observed and would ideally like to plan/resource in advance to save me time when the phonecall comes, but as we dont know when they're going to turn up my planned lessons may not fit in with the unit I have planned. Does this matter? Do they check that your lessons fit into your current units of work? I am just trying to find ways of being prepared!
