Sorry, long...
Ok imagine I have 2 kids, coming from very academic family. Younger one has always been in-your-face clever, it's very plain to relatives friends teachers parents. Reads obsessively and incessantly.
Older one has done fine, above average with flashes of brilliance in areas that grab her, but often seems away with the fairies, teachers don't rate her as very special but some are impressed with some products-like I said, as long as they are among the few that appeal to her wide and quirky interests.
Both want IQ tests out of sheer curiosity, so I have two done, one English language based and one non verbal, by a well known provider, supervised, official-not a full Ed Psych job just a taster (me economising!). I had thought about it in the past but the £500 each put me off.
Now just say that younger got to top 1% of the population (age normed) in the English based only. Elder got top 1% in both.
Ya ya I know this means nothing, very narrow, dated, etc but that said, assume they are both chuffed and it has boosted their confidence (and mine-I've always said number 1 was just as quick just not so focused and obvious).
What would happen if I told school about it, in anyone's experience? Good and bad stories or failing that your predictions? I'm talking about KS3 secondary school and an underestimated child who is having some underachievement and alienation (before the test!) issues.
