DS is 9 and in year 5. There is another boy in his class who has SEND issues and whose disruptive behaviour in the classroom has been an issue for at least two years. DS told us recently that this child regularly has "crash outs" and is violent to other kids. Yesterday they were all in the library when DS mentioned he didn't like the Dog Man books. This other boy overheard him and started yelling, then hurled himself on top of DS. DS fought back to get the boy off him and was not hurt.
The whole class was taken into the hall, where a deputy head came and shouted at them all and said "This class is a mess". They were then told they weren't having their marble time (reward time for having a good week). The boy who had jumped on DS was sent home for the rest of the day.
DS's teacher tried to call me that afternoon but I was busy and missed the calls. We've asked for a meeting with the teacher and deputy head next week. I'm angry that 1) the school can't keep my child safe, 2) his and other children's learning is being regularly disrupted, 3) the school uses collective punishment which is unfair and unproductive.
What do you think would be a reasonable response to expect from the school?
