The best teachers my DC's have had have either been the NQT's or those in their last year or two before retirement.
The ones that have been doing it for 5-15 years are the ones who look permanently stressed, tired, and worn out.
I don't know what the answer is, I just know what I want from a teacher, as a parent.
I don't care about Ofsted - out of the 4 Primaries my DC have attended, the best one for my DC's was the one that was never rated higher than 'satisfactory', as it was a school on an army estate with an exceedingly high turnover of pupils - by the end of Y6, you were lucky if one of your original 15-20 pupils from YR were left in the class!
The 'Outstanding' school my DC's currently attend is anything BUT.
They struggle to differentiate effectively for my DS1, who is working on lvl 7/8 in Maths, and lvl 6 in English, and they found it impossible to differentiate at ALL for my DD that was still on p-scales in Y6.
What matters to me, as a parent, when looking for a school is : How do they differentiate for 'high flyers', and how do they differentiate for DC's with SN's? Can they manage my DC's medical issues effectively? What do they do in the event of bullying?
Anything else is irrelevant, really. If my DC's all left Y6 able to read, write, and have FUNCTIONAL maths skills, I don't care about the displays, I don't want teachers doing paperwork instead of teaching my DC's, I don't want job shares because it is too stressful for my DC's.
That's all I want from a teacher, but Ofsted rules and sodding paperwork make that impossible.
