Does anyone else have a PG preschooler?

Are you worried about them starting school? Considering a tutor? Private? Homeschool? The whole thing seems overwhelming if I'm honest. It feels like this country isn't set up to handle PG tots. The school mine has been offered does have a (i think from what they've said) HG child in reception who they've had to readjust for which is a bit of a relief though.

My ‘academically advanced’ (horrid word) children played very happily with children with average abilities and children with learning difficulties. They grew up living surrounded by children with special needs. It was very good for them and taught them to communicate with people from a very wide social and intellectual spectrum. That has stood them in good stead as they entered careers which were communication dependent for success.
Peers with similar IQs (again somewhat disproven measure) are not essential. Intellectual stimulation can come from many sources - music lessons, language clubs, time with adults building mechano or Lego, trips out and family. Socialisation needs peers. Physical activities need to generate be age banded.
Work on the things your child isn’t so good at - even true genius has other limitations. Teach them to swim, to play rugby or dance, have them baking and sewing, craft and artwork to improve their imaginative and creative skills.

IQ is definitely not 'disproven'. There have been many attempts to discredit the concept but they have failed. IQ as a measure of intelligence (defined as abstract reasoning and problem solving ability) is one of the most robust and supported concepts in psychology, with high reliability and predictive validity. Criticise the OP if you must, but you can't dismiss the dilemma she faces on the grounds of IQ being 'somewhat disproven'. IQ measures something real, and big differences in IQ amongst classmates are going to have real effects on learning, behaviour and relationships within that environment.

Iq can be extremely inaccurate with 2e kids tbh. Better to do full psychometric tests with someone like potential plus tbh

I thought it was widely known that IQ tests for young children are not as accurate as adults' results. I thought a test at the age of 10 (or is it 11) is much more likely to be accurate.

I'd put them in school and see how they get on in the first year then reassess if necessary. It's important that he has the chance to socialise properly with children of his or her own age.

I would be worried if I thought my child would struggle but not if I thought they'd find it too easy.

Hopefully your dc will remain PG but I'd give it a bit of time and see how they do at school first...

Wisc doesn't measure to 160, only about 145 or so.
Some of the tests use different standard deviations. The ones Mensa use have a standard deviation of 25, whereas Wisc and Bas (used by Ed psychs and camhs) have a standard deviation of 15. So a child scoring 150 on a Mensa test (think it's Stanford Binet, but wouldn't swear to it) would only be scoring at 130 on a Bas or Wisc, but both are 2 standard deviations and top 2 percent. I disingenuously wonder why Mensa favours the one that gives the higher "score" 😁

So that 180 iq is meaningless, without knowing the standard deviation. On a 25 point standard deviation 180 would be a little over 3 standard deviation from 100, so it would probably equate to a score of around 147 or soon Wisc or Bas....much less impressive sounding.

Well sadly, my children (both of whom have SEN) are only four standard deviations above the norm, so we just bunged them into selective pre-prep and hoped they swam rather than sank.
I am somewhat disappointed that neither has tackled Euclidian geometry or Ovid in the vernacular yet
