@frozendaisy , it's not just one poster and one school though.
I am a teacher, so see the attendance issue from both sides.
This stuff ‐like this poster‐ is pervasive and very much at the front and centre of attendance initiatives up and down the country.
Recognising that the reasons for low attendance differ between families and that the support put in place or sanctions applied should therefore reflect said differences would be a great starting point.
And yes, of course 'suck it up, buttercup' has been in most parents repertoire as they've sought to get their DC to school. And much stronger, bordering on harmful, strategies and approaches as encouraged by schools and local authorities when things have become difficult.
Children are different: I can raise an eyebrow at neurotypical DC2 (a +97% attendance pupil), and she automatically knows what is expected and gets on with it. Easy peasy. Autistic DC1, on the other hand, cannot be budged, swayed, cajoled or even coerced into doing something she's scared of. She has been threatened, blamed, shouted at, man-handled, locked up and deprived of privileges in order to get her inside the school building (by well-meaning school staff who have been coached in a no-nonsense approach and not to take 'no' for an answer in order to keep children safe in education). As a parent of a child who struggles to attend school, you are very much instructed to get behind the above measures, lest you yourself are deemed part of the problem. It has taken a considerable amount of evidence and intervention from health care professionals to convince school that this approach is not in DC1's best interest.
Please don't underestimate the immense effort most parents of children with EBSA undergo to get their children into school.
