@Lebr ,
‘The number of children with SEN in private schools at 111,336, or 20.0% of pupils. Of these, only 7646 had an EHC plan, so around 103000 did not.’
I think it is really important to define SEN.
The private secondary I taught in had loads of SEN on the register, but only about 20% had a formal diagnosis. Pushy parents can easily get schools to put their children on the list. We had three classifications: EHCP, diagnosis of (say) dyslexia but not severe enough for formal diagnosis and ‘keep an eye on’, normally due to a ‘spiky’ cognitive profile and poor school performance.
The tertiary classification was often heavily parentally influenced as most parents don’t want their child thought of as just not that bright and, of course, SEN is linked to special consideration in examinations (extra time, rest breaks, private invigilation in a separate room etc).
It is a constant battle between private school SENCOs and pushy parents to not add to the list, as with a massive list it is hard to support those pupils genuinely in need.
The reality is that most private schools are very good at supporting mild and non disruptive SEN (mild dyslexia, dyspraxia etc) but have no interest in anyone disruptive, for obvious reasons.
In addition, of course, one reason private schools are so expensive is that the parents of high performing children (in large sets, say 24 pupils) cross subsidise the weaker pupils and SEN who tend to be in the smaller weaker sets (of 10 to 14 pupils). This isn’t much discussed, for obvious reasons.
