pdx, actually, Very Superior on this instrument is 130+. 120-129 would be considered Superior. But you may be including the confidence interval, in which case there is a little more latitude in aligning scores with classifications (though 120 is still too low to be Very Superior). Stable scores are generally more realistically acquired after about age eight or nine.

I would definitely agree that one must remember that any test is only a snapshot in time.
