Squishys - I recall something about a discrepancy of two (three?) or more standard deviations (15 pts per) between high and low scores qualifying as a disability, regardless of how
high the "low" is. Not sure if it's 2 or 3 SDs.
So you can be well above average in your weakness, but as long as it's at least 2 SDs below
your strength(s), it's still considered a disability.
(FWIW my poor DS had such a huge discrepancy "consistent with only 7% of the population" that the psych. couldn't even calculate his IQ.)
EDIT - it's TWO SDs... (just looked it up in my school notes

) We discussed it in our 3 hour session on gifted. Not NEARLY enough time to adequately cover the topic...
