The level of predjudice/stereotyping being proudly proclaimed by some "professionals" as "Knowledge" on this thread is truly frightening.
There's an old joke my mother (a special needs teacher with 40 years experience) used to tell - "If you come from Hampstead you are dyslexic, & if you come from peckham you are just thick". It seems that is still the public "truth". No wonder so she's angry about the sheer waste of human potential in the UK.
How can anyone claim to care enough about children to make a career out of working with them confidently declare "it's too late" at FOUR? In many countries that incidentially score far higher in the International educational league tables, children won't even START school for another 3 years. Homeschooling is rising at an exponential rate each year, amongst ordinary families & I can see why.
I have one sibling who was a straight A student, the other had a serious neurological disability. The one with the disability required infinately more parenting expertise, dedication and attention to achieve 1/10th of the A student. Any fool could have raised the A* child - all she needed was 3 meals a day and access to a library.
We are heading straight back to the dark ages at a headlong pace it seems, judging by the views expressed on this thread. It paints a very bleak picture for UK society 2 decades into the future.
