Your answer was that you spend a huge amount of time on MN criticizing other teachers and schools.
No it wasn't. It must totally baffle you how many posters came on this thread to say they find my posts helpful, but then they've actually read them.
incredibly disparaging of so many of your colleagues
Teachers usually don't have much of a choice and have to follow school policy. I have to do this sort of stuff myself, see the thread I linked to 'I make up sublevels'. My thinking on reporting to parents has partly been informed by the vast numbers of posts I've made over the years explaining stuff to parents who don't understand how their DC are doing and have asked for help interpreting reports.
do you ever get out of your own department
Teachers have 5 days INSET per year, what do you think they do in it? In addition I spend lots of time on twitter reading the latest thinking on e.g. Assessment by writers such as Daisy Christodoulou. Also, I attend education conferences in my own time and out of my own pocket because my school doesn't have any budget for CPD.
What do you do?
