Age 11 CAT scores vs US SAT results

[countryl]

There's some research which suggests that UK CAT score results at age 11 have an 81% correlation with GCSE results at age 16.

My question is, has anyone ever seen research with has looked at UK CAT scores at age 11 and compared them to US SAT (not UK) results? I'm looking for data/research on the subject. ta

SAT stands for Scholastic Aptitude Test and I believe it is supposed to be an aptitude test rather than an achievement test. (The firm also offer subject matter achievement exams). There is a big difference between the two concepts.

To what extent does the CAT assess aptitude vs achievement? If the answer is ‘not much’ I would expect a weak correlation with the SAT. However I am personally convinced that solid achievement helps a great deal with the SAT, as does practise

That's a good point you make. The GCSE tests are achievement tests. So, the research I linked is measuring the correlation between a cognitive ability test (CAT) and an achievement test (GCSE).

Given that one can sit the SAT as many times as one likes (or can afford), which SAT results would you use in the comparison?

’Cognitive ability’ in the four domains assessed by the CAT and ‘scholastic aptitude’ as assessed by the SAT seem broadly similar. (Knowing nothing about the CAT I had to look this up) Bearing in mind the comment from @MarchingFrogs one might therefore expect a reasonable correlation with the first SAT attempt, at least as good as with GCSEs.

I suspect this is a niche area and I am not aware of research, but education is not my specialism

Another good point. Hmm, I suppose you would want to use the first one taken. That said, it would be fun to see it done for first test taken compared to best results to see what if any was the difference.

@poetryandwine I think what you raised earlier is important. The original research I referred to was mixing cognitive ability and achievement testing. I think a CAT-to-SAT is intuitively a better comparison. Mixing UK and US tests is most certainly very niche. I doubt I'll uncover any such research.

Maybe I can find a UK analysis that looks at CATs versus another aptitude test at older ages. That might at least sort of get at what I'm after.

Thanks for your input.
