The primary school my children attend has under 100 pupils in total (reception up to year 6). They have a high amount of SN and SEN numbers.
My eldest has SEN along with 5 others (that we know of) in his class of 23. My youngest does not have sen but there are 8 children (that we know of) who do have SEN/SN in his class of 27. This ranges from developmental delays to an Autism diagnosis (Asperger's, Sensory Processing Disorder etc).
Unfortunately I cannot answer your question regarding why numbers are "'so high'" however I can tell you that SN/SEN children are able to access intervention, help and diagnosis much more easily compared to 'back in the day' when so many were left to struggle through the education system or sent to 'naughty schools'. Thankfully there is a better understanding and awareness and significant research has been carried out over the years. Teachers and Early Years workers are also trained to recognise signs.
It is not ''accepted as a normal level of dysfunction'' as you have worded it. There is nothing 'dysfunctional' about my child. He requires a high level of support in order to access the curriculum which he is entitled to access just like every other child in his class.
To answer your other question asking ''why so many children have physical or cognitive issues that affect their learning?"
My son does not have a physical or cognitive 'issue' and neither do his friends who share the same diagnosis as him. It is neurological and present from birth with no apparent reason or scientifically proven reason. He was born completely naturally on his due date. I was a very health conscious, non smoker or drinker prior to his pregnancy and during.
My youngest who is neurologically typical was born 6.5 weeks prematurely following a very traumatic birth due to lots of complications in pregnancy. He has always been very advanced for his age. Walking without help at 10.5 months, toilet trained day & night before aged 2. Reading and writing fluently at 3 years old.
