Observed by a LA inspector and HOD, with a group from hell. Managed their disruptive behaviour, got them working, got them learning. Satisfactory. The inspector could come up with no ideas how I could have improved the lesson, my classroom management, lesson planning, activities, style of teaching were all excellent (?) So I asked the obvious question - why satisfactory? Because in the first 5/10 minutes of the lesson some weren't learning and according to the ofsted guidlines it couldn't be anything else but satisfactory.
