WJ III EWOK (Evolving Web of Knowledge) v3.0 is now available

I'm very pleased and proud (actually, more relieved) to announce the third revision (v3.0) of the WJ III Evolving Web of Knowledge (EWOK), which was first announced in March of 2006. Click here to visit the original description and post. Click on the other link to go directly to the new WJ III EWOK.

Even if you do not like the Gv MindMap navigation option, I would urge you to view this "big picture" in order to see the information icons that designate branches/sections that include new material.

Feedback is always welcome.

It seems intelligence tests are all being affected by CHC Theory. However, the main serious difference in my mind between say a Wechsler and a WJIII is that the latter won't report differences between cluster scores. Am I right about this? In other words, while reporting normative scores for the clusters, there is no way to actual know if a difference is significant - say someone has 125 for both crystallized and fluid clusters but a 102 on a measure of working memory (102 is in the average range), there is no way to know if that 23 point difference is significantly suggestive of something interfering with short-term memory (though it sure looks like it!). Am I right about this as a limitation of the WJIII?

Hi Daniel,
If you use the variation and discrepancy procedures in the WJ III, you will get very precise information about the significance of differences as well as the frequency of those differences. If you have the NU Technical Manual, take a look at pages 7-12 for an overview of these procedures and then 34-37 for an explanaton of discrepancy norms in the WJ III. If your interest is in exploring differences among cognitive abilities, then you would use one of the intra-cognitive variation procedures, most likely the extended one. If you want to examine differences between the individual's GIA-Std score and one or more broad CHC factor scores, then you would use the GIA-Std/Cognitive cluster discrepancy procedure. Hope this helps clear things up.
