Firstly, I will confess I have changed some details as the real situation will identify me completely. If my story doesn't add up, it's because I am crap at sticking to the story and the changes, not because I am lying totally!
DC started school at school A. Was lovely to start with but a child there was a complete nightmare, causing injuries to lots of children, huge disruptions etc. DC got hurt on a number of occasions, as did lots of others. School refused to deal with situation and actively lied. After a severe head injury, we moved schools, to school B.
DC settled wonderfully. Less than a year later, the child also moved to the new school
. They left before being excluded from school A.
We were devastated, as were a number of other parents - this child is well known throughout the local area. We decided to move schools, but school insisted they could cope, so we stayed.
Initially all was fine. However, on moving up to next class the situation has deteriorated massively. I have struggled to get DC to school. Some DC have already left the school because of them. Many children have been hurt. The school, whilst initially on the ball are floundering and now becoming defensive. There are fights everyday, which are ignored.
It is a small village school and the ethos has changed completely. The school and governors are not dealing with this, the children do not seem to be being punished - not kept in, not excluded - for extreme violent behaviour.
The incidents are so extreme we, and others, are concerned about safety. Some parents have contacted the LEA and are awaiting response.
We have contacted some local schools and have identified places.
But, should we move again? What if child leaves again and comes to new school -we didn't believe it would happen the first time so now anything seems possible. If we wait too long, spaces could fill up, school A is now in special measures so children could be leaving both school A and B. We don't want to move and then they exclude anyway, but we have lost a lot of faith in the school and can see DC personality changing.
We are going in to see the head again, but just don't know what to do 
Any advice anyone?
