Schmidt ( International Journal of Selection and Assessment , 20, 1–13 (2012)) argues that it is possible for scores based on measures of general cognitive ability ( GCA ) to have content validity evidence. This commentary examines this argument further. I first decompose the various lines of validity evidence that may exist for GCA scores. Next, I consider whether GCA scores can have content validity evidence and whether they cannot. I conclude with several observations about the meaning of content validity within GCA research and practice. The bottom line is that although I agree with Schmidt that GCA scores can have content validity evidence, I am not sure such evidence tells us much about the overall validity of GCA .
