3 sets for DD all paid for by state schools.
First at 7 when they were working out why she couldn't read or write at all but had a very extensive vocabulary and was obviously clever. She has extremely high VR, NVR and spatial scores and exceptionally low working memory and is severely dyslexic.
Second set at 10 to support school applications.
Third set in Y8 as school gave them to all students as no SATs.
Lots of parents are just interested, but I suspect it is quite rare to have an IQ that high without some additional issues to contend with.
Had primary not paid for the first set, we would have done as she was obviously struggling and it wasn't clear exactly where the problems were.
