It was me who made that suggestion elsewhere. 'Link' is my other pseudonym.
I was not (I don't think) referring to the 'standardisation' of the CAT test as such, but merely the spread of the scores, which I feel could be similar to cats. It seems to me that the difficulty of the test has caused a much larger amount of dc's than normal to score close to the mean (100).
So I expect to see a large clump of scores around and close to the average (90-110), with far fewer scores in the higher and lower range. This is just literally what I think and I am not an expert, I have no analytic skills to speak of other than typical Maths. I'm just an over-interested/obsessed/scared parent
Edit: I just checked elsewhere and have seen new info (from an expert) that you may have been referring to. So please ignore me on both accounts
