My husband and I attended a seminar session by Dr. Deborah Ruf this summer.
Her book is definitely on my top five recommendation list for parents of gifted children.
She pointed out that she has met parents whose children have received astronomical numbers on IQ tests, but stated that their children did not meet the developmental milestones for levels four or five gifted. She commented that the high scores is those cases are misleading.
I tend to look at early developmental milestones over the course of years as a slightly more valid indication than a three hour test session. Most schools around here couldn�t care less about either of those, so I believe above level achievement test results are the strongest supporting indicator for academic modification (even these can be artifically low if the child has not been exposed to a higher level education). I have rediscovered through my son�s experiences how some teachers manipulate grading, so I don�t consider straight As the most compelling evidence of intellectual giftedness.
