Since Davidson only accepts the SAT as a college placement test in place of an achievement test, I wouldn't say that their doing so really weighs in favor of a high IQ correlation. The correlation is whatever it is; we don't know it; and it's likely lowered in the newest version.
That is an interesting point and brings to mind the achievement/ability correlation question. Do we accept high achievement as proof of high IQ/intelligence in all instances? I'd argue not. I know plenty of kids/teens/probably even adults who achieve at a level that is higher than their IQ. I do think that hard work, motivation, exposure, and probably a number of other things play as heavily into achievement as does intelligence. I'm curious as to others' thoughts, though.
