AIBU to expect an apology?

[SpeedRunParent]

DC 12 goes to a naice grammar in Kent. One boy in her year group has physically assaulted her twice ( with witnesses) and has called her a slut; reiterating that slur after the second incident.
The first time he put his hands around her neck and squeezed, leaving her shocked and breathless, because someone ( not my dc) had annoyed him somehow. This is the occasion on which he called her a slut. (Not that it makes any difference but my dc loathes all the 'he fancies you', this one loves the other nonsense).
On the second occasion, same boy ( part of her wider social group) had an umbrella taken from him by two other group members and it sounds like the umbrella was damaged. My DC absolutely did not have anything to do with this either ( the school has assured me of that). This time the boy slaps one girl in the face, throttles a boy and punches my DC hard in the gut - resulting in her needing to go to the med. centre.
The only sanction this boy has received has been days isolating during lessons.
AIBU to have expected that my daughter receive an apology from this child? If a person does not acknowledge their misdeeds and make amends, how is he going to learn not to repeat them?
P.S. there is no suggestion that this child has any SEN, all we know is that the mother says things like 'boys will be boys'.

Your approach is excellent, I hope your daughter is doing okay. I've experience of schools being shockingly lax about vicious bullying. In my daughter's case it took the Head going on leave and a meeting with the deputy to get any sense from them. I'd advise backing up your conversation with the Head with a calm, detailed, letter outlining your concerns and repeating their response and why it is inadequate. Copying the governors. It will be useful when you speak to the police as well. For your daughter is there anything you can do to strengthen her friendship circle? Does she have friends not in this group who can be encouraged? There could be a backlash. You sound like a wonderful mother good luck x

Good for you taking it further. It’s completely unacceptable, and in some ways the school have done you a favour in that he admitted it during the reconciliation meetings and that member of staff can act as a witness to this.

And we wonder why DV is so prevalent, when you have Head Teachers wanting a fxxking reconciliation meeting after a child has been strangled.

OP, I feel so sorry for your daughter.

This is the sort of information that you would like to know about a school.

The head is appalling.

A blind piece in the local paper that the parents of a young student had to go to the police for support because of the Named school's refusal to take any action bar asking the victim take part in a reconciliation meeting, would definitely give parents pause for thought.

The optics would be very poor IMO.

The school needs its appalling reaction to unprovoked violence published.

Police involvement will have to be noted by the school its annual report?
Isn't this why some are so reluctant to take action.

The best of luck OP to you both.
