5yo DS excluded from school - what now?

[IsItMeOr]

DS is in reception, and is currently on school action plus with a 1-1 support intervention this half term for his behaviour issues (primarily hurting other children). We're gradually getting through the health assessment process, seeing CAMHS for an initial assessment, have an assessment appointment booked with SLT in a few weeks and on a 6-12 month waiting list for a multidisciplinary assessment for a possible social communication disorder.

DS has today been excluded for two days because he attacked another child in his class. This is described in the letter from the school as an assault.

We have a meeting with school on Monday. Can anybody advise on what we should expect, and what we should be asking?

Thank you in advance - feeling a bit overwhelmed right now.

Hi I've only signed up to mumsnet as I was googling about my son and came across your post. We are in an all but exact same situation although the school are very good with us it is very frustrating to know what to do for the best.
Our school have a meeting with us to set up plans of action every 6 weeks.
May I ask how it came about that your son has a 1-1 support? It's fantastic that he does. Our school have said that until he has a diagnosis and possibly a statement that this wouldn't be possible.
