I'm looking for any books that can help me understand the achievement vs intelligence gap that occurs with some children. It seems like most the books on child development, gifted children discuss issues that occur when IQ is greater than achievement. Yet,I'm actually looking for information on the reverse situation (i.e. IQ < achievement). I have seen a couple of books that address that this does happen but not in detail nor any theory as to why. I appreciate any resources that you can suggest!
