Cathy, I understand that they would have to add in the decimal digits since HG seems to start at 99, and PG seems to start around 99.9? Such a difference within that one percentile point.
ColinsMum, It may be that in my sleep deprived state I just couldn't find where the author indicated the test used. (In addition to my DD5, I have baby twins that seem to think that sleep is for wimps.) I am reading A Parent's Guide to Gifted Children and many, many websites. The book was recommended to me by the psychologist that administered my DD's test. He also recommended Hoagie's Gifted website to me, so I'm hoping I can assume it is well regarded to be accurate.
