Graph the results.  There is a free website that allows you to simply input the info and it graphs for you.  You can print it and save it.  It's really easy.  Graphs speak volumes.  Make sure that you use the subtest scores.  There are conversion charts for changing the scores to standard scores.  Make sure that you start the graph with the full scale IQ.  That helps to show the standard deviations.
