That why I stress procedure.
You don't comment on what happens to the other child - other than say you think they need intervention and keep repeating this rather than punishment.
If you have an incident you keep saying 'what are you doing to safeguard my child'. You can't comment about other children. You can get an answer to this question - you want an action to safeguard your child. How can this be prevented from happening again, with steps of action and implementation. They have to do this. They can't do nothing.
If another child is then hurt, after you have done this, they need to ask the same questions. Get everyone on the same page. It tightens the screws.
If it happens to multiple children over a course of time and you all have it on record (remember you want to create a papertrail on all this), this is the point you can start to go over the school and raise it with governors and then on from there.
You need to understand the system and how to get the school tied in knots and be able to prove failure to safeguard your child.
If multiple child then get sucked in, you show a clear problem. This creates a greater case for intervention for the school - including removing the child if necessary.
Schools can't get rid of a child without evidence and a papertrail.
In our case we were fully aware that parents concerned we're not taking the issue seriously enough and refused to engage with services. By saying to school what are you doing to safeguard, documenting everything, it meant they had to get a third party organisation involved because of concerns. This in turn put pressure on the parents. They were ultimately forced to engage this way. This child is now recieving support they need and child themselves is much happier. It has improved things for the whole class. He is still in the class, but it's a world away from what it was.
This child had physically assaulted at least seven classmates over the course of some time. Some were not in school time and were witnessed directly by parents. I reported one such incident to school, against another child, as part of what was happening to mine stressing that I knew they couldn't do anything about it but to make sure they had on record it was happening in multiple settings and when the parents were present as it's part of a wider safeguarding picture.
We knew one other set of parents were making complaints about what was happening to their child, separately. We did not coordinate and they were much more confrontational and didn't go by the book in the same way and weren't getting taken as seriously. We kept each other informed though.
Genuinely I do think going by the book made us much harder to dismiss as the school had to demonstrate responses were correctly handled and appropriately. Going by the book, the school knows they don't have a way out because you understand how the system works and that you are capable of navigating it and ultimately dropping them in it if they aren't squeaky clean.
