Differing views of what good behaviour is, and different emphases in training, means it is hard to tell what actually works best in developing good behaviour for all pupils.

Teachers’ Union The NASUWT has created posters, similar to ones seen in NHS hospitals and railway station, making clear that abuse to teachers is not tolerated.

Behaviour expert and former teacher Tom Bennett will lead a programme, where a network of expert schools will be identified to help teachers and school leaders in need of support.

The reforms to training will mean that all teachers will be shown how to effectively manage behaviour in their first two years in the profession.
