Between intelligence test %26amp; achievement test w/c do you think is better in predicting academic performance?
I'm not sure either type of test would predict academic performance, although the person who does well on an achievment test at least knows x amount of material, which would give them at least that much of a head-start toward future academic performance.





Many students do well in both types of test, but find school unchallenging or otherwise not suited to them - and underachieve. For children who do extremely well on intelligence tests there could actually be a higher risk of academic underachievement.





Provided a child does not score below average on intelligence or achievement tests, I am under the impression that - in general - children who score slightly above average on any tests may be the most likely to thrive academically. Schools are generally aimed at the broadest part of the bell curve, which means children who are around the average mark. Of course, the child who is just above average will have an advantage. Since schools are aimed at the average and just above it would make sense that the students who thrive will be those to whom the policies, material, and environment are aimed.





Of course, there can be exceptions; but I believe, in general, the students who thrive most are the slightly above average while the well above average and extremely above average students tend to get lost to the point where they may be satisifed with B's or even C's without much participation and effort; but because they are intelligent enough not to allow themselves to sink too low academically, they tend to do just enough work to have acceptable but not outstanding achievement in school.
