This was their response:
As you say, I had intended to get back to you at the end of November and did not until yesterday for which I apologise. This is my own fault, for which I apologise again.
You have written that you were "wondering what was happening, especially at school as it is silent." However, I understand that you have communication from class staff via Class Dojo. I am unclear as to what you mean by you having "had to push for answers with no luck." I have now responded to this issue which you have raised with me. I am also not clear what you mean by "It's becoming suspicious.".
You say "We have not seen anything like it before 25/11/21 when DS was in school or since." This reassures me that you agree DS is not coming home with bruising after having been in school. "We don't know how it happened, could he have been bitten by another child?" From the looks of the photos, I wouldn't think they are the result of biting. I do not believe that an interaction between DS and a peer which resulted in bruising would have gone unnoticed. As mentioned previously, I am interested as to your thoughts whether these may have come from his unsupervised outings in the community.
You note that at home you de-escalate heightened behaviours quickly, which we as we also endeavour to do. Please could you share some examples of what you have found to be effective strategies? It is a shame to hear that he has dented your car and attempted to break mirrors, however I am glad that the bubble bath helped him to regulate. As you mention, there is information regarding self-injury on the federation's website; this is an information section.
At this precise moment, I do not know the exact reference to the head banging behaviours from the EHCP Review report you have attached. I will be seeking further clarification around this. Would you like to arrange a time to discuss this specific reference with me before half term, or would you like to discuss it at the recently arranged CIN Review which is scheduled for 23/02? I am unable to comment on your engagement with ASD Specialist School as our school has not been party to this.
You have put that "school is uncommunicative and secretive, ignoring me.". On the contrary, I would remind you that a CIN Review meeting was recently brought forward at my suggestion to ensure you felt heard and supported. I understand that you have made a Subject Access Request (SAR) which will be responded to in due course.
I know that we all share the same wish for DS to have the best support to help him fulfil his potential. We are, as ever, keen to work collaboratively with you on this.
They are avoiding any mention that they investigated (or didn't) the self injury. I don't believe they did. I think it happened in school but can't say so to them because I actually can't prove anything/know.
The class teacher has not been in for a week and only TA's covering. Should they be covering with someone of similar qualifications?
Should there be an official procedure to self injury?
What do you think?
