I think the difficulty with teaching (vs, for example, financial work) is that so much of the output is not ‘visible’ on paper in the same way.
So, for example, an experienced teacher could teach a lesson with the objective ‘To calculate unit fractions of an amount’ with very little more than that objective, their own personal knowledge of that class, a jar of counters, a whiteboard and a pen. Sone children may have almost no work in their books after the lesson, having used the counters throughout, but will emerge from the lesson with a secure understanding. Others may have a variety
of numbers written down in their books.
The teacher will have a good knowledge, as a result of the lesson, who understands, who doesn’t, and what tomorrow’s lesson should look like.
However, for inspection, everything must be documented (and obviously as inspection is short notice, this tends to mean that documentation becomes a routine burden even if not required). There needs to be a written plan. Specific adaptations must be detailed as evidence of meeting SEN needs. Marking books is done to evidence that the teacher knows what the child can do - and so on.
With such a high-stakes inspection system, so much is done ‘just in case’.
