Gifted Issues Discussion homepage Forums Age or Ability Specific Forums High School Verbal SATs and the Verbal Comprehension Index

I don't have the answer to your question, but would like to share my personal experience with SAT and IQ.

I have a WAIS III 145 VCI (although my other 3 indexes are much, much lower with a FSIQ only in the average range). I achieved only a 680 on Verbal SAT at the end of Junior year of high school.

I believe that while there is a definite correlation between Verbal SAT and VCI, it's only moderate, since two thirds of the SAT Verbal section is composed of reading comprehension, which is not a factor for VCI at all. Only a third of the section relies on vocabulary and verbal reasoning which correlate to VCI more.
