5 year old leaving classroom unnoticed

[Charmtaste]

My 5 Year old has ASD. In Reception he used to run away a lot. His EHCP states that he might run away.
We have moved to a new area and they are re-doing his EHCP. An ED Psych observed him at his new school and her report states that he left the room to go to the toilet without permission and his teacher did not notice he had left. She also stated that he punched himself in the face on 3 separate occasions and this also went unnoticed.
Should I raise this as a safeguarding issue with the head? I do not know the classroom setup or how easy it is for him to escape from the toilet area.

I would broach the subject with the teacher to clarify what the process is.

They will have seen the report and should be considering appropriate action.

In our reception room, the toilets are adjacent to the classroom and can only be accessed via the classroom. Children use them independently.

Does he have extra support? How many members of staff are in the room?
If the teacher is on their own with the whole class then they cannot keep track of all children at all times.
If I’m dealing with one set of kids I’m not necessarily going to notice a child at the other side of the room punching themselves. And young children do similar kinds of things all the time just to get a reaction from a friend etc…
Leaving the room is a trickier one. Again if there is only one member of staff then you really are relying on the children to understand and follow the rules that they ask before leaving the room. In a busy classroom it is very difficult to keep track of all 30 skids all of the time. It’s also highly likely that you child is not the only who requires extra attention.
What does the EHCP suggest as a solution to this issue?

The teacher knew the ed psych was observing him and it's highly likely she ignored him on purpose (or seemed to be ignoring him). They need to see what your DC is like without constant supervision in the hope they'll get some/any funding for extra help.

I do think you should speak to the teacher about it though just so she can (hopefully) reassure you about it
