I have been thinking for a while now that Headteachers and inspectors from a teaching back ground should have to do a teaching practice of a few weeks every few years where they are expected to teach the way teachers do NOW, not years ago when they were in the job. This could be a day a week or a block of time and they would be required to provide evidence of observations made by other staff at the school, consultants and ofsted or link inspectors.
I truly believe that they would be better at their day jobs and that staff would have more respect for their head teachers and inspectors if they knew they had hands on knowledge and experience that was recent and subjected to the same standards.
