I think some of those changes needed to come in though.
If I reflect on my own school days I can recall 2 subjects where we didnt study anything for a year, one where we spend more time than was reasonable running around the room and writing in bubble writing on sugar paper. Very little learning happened at KS3.
The way I see it on reflection of my own school days, if you were bright and motivated then you would get A/A*, if you were C/D borderline then you got extra help, if you were lazy but above a C you could coast and nobody bothered with you and if you were below a C then it was essentially baby sitting because you'd do level 2 again at FE college anyway.
I've never had my planning checked as a teacher but have had book looks. I don't see an issue with it as a common sense approach.
Learning walks: maybe if people had checked what was going on in some of my lessons we might have learned more, spent less time making board games in KS3 etc. If you're doing your job then learning walks as part of a sensible overview shouldn't be a problem.
Book looks: If you're teaching what you should be teaching then you can stand by what your books look like. I did no written work for a fortnight with one class. Nobody said anything to me because from learning walks and book checks it was clear I was doing what I should be doing and therefore was using professional judgement
I like Stephen Ball's work a lot. I do think in practice that a lot comes down to differing ideas of what reasonable is.
E.g. Multiple data drops for y11 every 2 weeks is a ridiculous waste of time and probably not giving useful or accurate data to so anything with.
A marking policy of mark in detail every 5 lessons and have 4 different colours for peer and self response is a waste of everyone's time.
Both of those are an issue with stupid and ineffective school policies more than they are to do with reasonable professional accountability. The only people I've worked with who have had an issue with reasonable professional QA in schools with reasonable policies are people who want to do their own thing and then if students don't do that well, they blame the students.
