Thanks!

And, of course my daughter, being the perfectionist, wanted to take her time on the timed portions of the WISC. My understanding is some of those subtests are all but nulled out if even a guess isn't made. (?) We never coached her, nor even suggested guessing answers.

The argument for grade skipping by way of deviation scores kind of falls apart, no? After all, the age ratio thing would correspond to older-aged kids. I also understand that because the LM simply has more difficult questions and problems that it allows someone with a wide conciousness (for lack of a better word) to actually perform. When something like the Binet 5 is used, one or two missed questions can ruin the whole score.

Very interesting stuff. Thanks again
