School advice

Hi 

I am looking for advice or even some strategies that may help us. We have a little boy that has started reception class and he has very limited communication with us, we have tried many different things such as, visuals, a communication book, learning around his favourite toys, quiet room and many more. He has outbursts of violence towards the teachers and staff trying to support the child. He is in mainstream school which have other autism children but none that harm others or is not learning. Our concern is that everyday that the child is in school he is not learning as he is running around the school, climbing and being violent to any members of staff that try to comfort or stop him from what he wants to do at the time.

Any advice would be appreciated 

Thank you
