In our district students who have borderline scores or have really high scores in a particular area (but not overall) are put in a "Challenge" pull-out.  This is especially beneficial to the low-SES students who have not had a home environment conducive to intellectual development.  We have found that many low-SES students later score in the gifted range after being exposed to enrichment activities in a challenge class for a year or two.
This made me smile!  I hope there are other districts doing the same!
