I would suggest that it is engagement of multiple skills at once. For example the adults need to provide secure spaces while at the same time developing stronger personal networks with the community that surrounds the school. I have attached a flyer for a volume that might be of some help.

Thanks Curtis. I have sourced the document and will explore it to the fullest to be further empowered on the topic.

Defusing confrontation, empathy, non-violent responses - verbal, body language etc, good will, guts, salespersonship to maintain a focus on learning.

Thanks Mark. Clearly from your discussion teachers in troubled schools need skills way beyond academic and I am not sure the leaders of the Education System is ready to put the necessary facilities in place to ensure that teachers who work in these difficult schools acquire the needed additional skills required to eliminate violence and maintain the academic focus on students' learning.

The emotional input by and demand on teachers is undervalued by bureaucratls, politicians and even teachers. It is similar to that required by nurses and is similarly undervalued.

I share your view Mark.
