In discussions with others, due to the very unlevelled nature of pshe, I'm leaning towards excellent in lesson assessment, involving children's views as well as teacher judgements.
This requires thoughtful preplanning on what is going to yield the most open views from/of the children's knowledge and understanding.
In this way next sessions can be planned, questions to further thinking skills and skill application can be asked and interventions can be managed.
This isn't a pick up and run lesson brief though with a tick or cross at the end for assessment. This requires engaging with your children. Consideration of their needs and how to progress them. To foster this attention to detail in others may be difficult!
