No, I didn't (I've forgotten your affiliations with this stuff... but if I recall something public sector so maybe now you've said that, NUT?

).
It should be easier to dismiss under performing teachers, and they should be held more accountable for outcomes (granted we need to fix measurement of outcomes too). Fundamentally there should naturally be greater attrition and churn in the profession, but there isn't. Poor teachers are being shuffled around, rather than dismissed - I mostly blame the NUT for that.
