Reading a report is different from being on the other side of the process.
What happens is that the school is put under enormous stress. They have to produce reams of data, none of which enhances the education of the pupils but takes the teachers away from their primary task. And woe betide them with OfSted if the tiniest things is not exactly recorded.
If a problem is found, OfSted just get up and walk away, leaving the school with a challenge but no help or support (either financial or otherwise) to meet the required target. There used to be support from the LA education department, but years of underfunding means that they have dwindled to virtually nothing. They used to supply support with courses, professional development, legal updates and advice, and buildings and maintenance support - virtually all gone now. Did you know that if a school wants these things they have to pay for them out of their budget? - budgets that are insufficient to start with. Schools have to take out Service Level Agreements (SLAs) to get this sort of support - they have to second guess what they might need and take these out.
The old style schools inspectors used to provide support if a problem was found - no longer. And they would develop a relationship with the schools and make sure help was forthcoming when needed.
Never forget that the things that OfSted measure are not necessarily the things that make a school good - they are government-contrived parameters which are mainly simply burdensome to the staff and take them away from their real task. And never forget that they measure them in a one-off visit, so their validity is suspect anyway.
As an example, a school can be downgraded on pupil attendance. How is this the school's fault? Can they go round all their pupils and make sure they are getting out of bed each day? Can they prevent children getting sick?
There are strict academic targets which take no account of the number of pupils in a year group with SEN, or the size of the group which can make the data invalid.
And so it goes on ....... teachers being deflected from their primary task with all this window-dressing.
