I've just accepted a job in a new school. After 4 years in a RI school, and 2 DC's in between, it was either that or leave teaching altogether.
The Head is amazing. He's taken the school from 4 to 2 (with outstanding for behaviour and leadership) in 4 years. He doesn't believe in graded lesson observations, but supportive peer observation which helps teachers improve, all his slt teach so they can empathise with teacher experiences - and they do all duties and detentions. He doesn't believe in overly structured lessons or mini plenaries, and teachers can be as creative as they want.
It makes me feel that there's hope for the teaching profession. We need more Heads like this! Just thought I'd share.
