Wow, you guys are great!
This is a great discussion. Cathy I don't understand also how it works. It does not make sense.
My DS at 4yr 9mo
Information: raw score 31, scaled score 19, >7:2, 99.9%
Vocabulary 29, 15, 7:2, 95%
Word Reasoning 24, 17, >7:2, 99%
Block Design raw score 36, scaled score 19, >7:2, 99.9%
matrix reasoning 23, 17, >7:2, 99.9%
Picture concepts 20, 17, >7:2, 99%

I would think that anything as >7:2 is as high as it goes provided by the test. What would constitute 7:3?
