I prefer progress as a measure of success
Yes, but we should maybe appreciate that there is no single universally objective measure of success or performance for a school.
Progress is a function of the starting level.
All else being equal, a school will show more progress if the starting level of the kids was low to begin with.
It's a good thing if a school makes kids progress more, sure, but this doesn't mean that a school whose kids progress less, not because there is anything wrong with the school but simply because the starting point was higher, is inherently 'worse'.
Also, how do we measure progress?
A common trait of many super-strict schools (e.g. Micaela) is to have a very narrow choice of options, and to limit kids' options based not on what is best for the kids but what makes the school results look better. So a kid may be prevented from taking a subject just because the school doesn't want that kid to spoil the school results. It happens. Sure, kids need guidance and if you struggled with GCSE maths maybe further maths at A-level isn't for you, but there's a spectrum.
Another common trait is the repetitive teaching to the test. See the example above about Micaela. Maybe this method gives a school good results to show off, but it doesn't arm kids with the slightest trace of critical and original thinking, and it doesn't prepare them for life after school. But, hey, the box is ticked.
FWIW, on Ofsted, my opinion, which I know not everyone agrees with, is that:
- if Ofsted says a school sucks it's likely to suck
- if it says it's good it means little, it could still suck
- the difference between good and outstanding seems ambiguous at best, random and capricious at worst
- Ofsted is clearly unable to identify problems with excessive discipline and emotional abuse (Holland Park school, Mossbourne, etc)
- Ofsted sucks at spotting illegal off-rolling and all the other million ways in which a school can game the inspections (asking difficult children to stay home, etc)
