This is more for teachers/people who work in schools ...but happy for opinions from all....of a what would your school do...
If a pupil didnt come to school and hadn't been reported absent by their parent.
Then you when the parent is called they tell you to go and ask the child's sibling (who attends the school) why she isnt in and hangs up.
About an hour later the absent child (year 5) phones the school to say she's unwell with a tummy ache.
Would you expect this to be raised ad a safeguarding concern?
