[quote=Anonymous][quote=Anonymous][quote=Anonymous]For most of the tests, the average is 100 and the standard deviation is 15. I'd look to see what scores are more than 2 SDs from the mean (so below 70 or above 130) and then make sure I understood the implications of that.[/quote]

In addition to this, I'd compare scores and sub scores within and across all tests, looking at places where there was a difference of more than 22 points (on the tests which have 3 digit scores) and more than 3 points (on the tests which have single digit scores.  The significance of testing lies not just in how far from the median a student is but also in significant discrepancies among abilities and/or achievement.  A kid who has a 115 verbal IQ should not have a 85 in reading comprehension. School will tell you that both scores are "average" (although one is "high average" and one is "low average), that is a significant discrepancy of 30 points where IQ indicates good verbal ability and achievement is significantly below ability (suspicious).  Similarly, a kid with a Perceptual Reasoning Index score of 10 but who has a Block Design score of 15 and a Visual Puzzles score of 5 may appear to have "average" perceptual reasoning overall, but actually has an extremely wide significant difference in sub scores that makes the overall average meaningless.

Is it true that if you have at least 20 points between verbal IQ and written IQ that indicates a learning disability.  [/quote]
