I am pleased to announce that version 1.1 of the WJ IV Evolving Web of Knowledge (WJ IV EWOK) is now available.   This is your one stop internet source for keeping abreast of announcements, research, etc. regarding the new Woodcock-Johnson IV Battery.  It is the same concept used for the prior WJ III EWOK.

The WJ IV Cognitive Battery and Beyond CHC Theory

For individuals who could not attend my NASP 2015 WJ IV mini-skills workshop, or those who did and who would like to view all slides shown (and those not shown) or others who want to know, you can now view the slides below that are posted at SlideShare. Enjoy.  If you click on the SlideShare link you can view other PPT shows I have available for review.

The WJ IV Test of Achievement--Alternate Forms Equivalence Assessment Service Bulletin

A supplement to the WJ IV technical manual, which provides new (and some previously published) equivalence evidence for the alternate forms of the WJ IV Tests of Achievement, is now available from the publisher (click here). As described at the website:

This bulletin is an executive summary and discussion of all extant alternate-forms equivalence data gathered for the WJ IV Tests of Achievement.

The WJ IV Technical Manual (McGrew, LaForte & Schrank, 2014) contains information about how the three forms of each test were constructed to be equivalent in content coverage, difficulty, and measurement error. A summary of these procedures is included in Part A of this bulletin. Part B includes the descriptions and results of two recently completed alternate-forms studies. These studies contribute to the accumulation of evidence regarding the equivalence of the WJ IV ACH Standard tests. Additionally, these studies present an example of methodology appropriate for evaluating empirical evidence for alternate-forms equivalence in the context of individually administered assessments.

WJ IV update: WJ IV g-scores (GIA,BIA,Gf-Gc composite) correlations with WISC-IV/WAIS-IV FS and GAI IQ scores

In the WJ IV technical manual (McGrew, LaForte, Schrank, 2014) concurrent validity results are presented for the WJ IV COG with the WISC-IV and WAIS-IV (click here for WJ IV COG overview and select correlation information from tech. manual).

A number of psychologists have asked about correlations between the primary WJ IV COG g-scores and the Wechsler General Ability Index (GAI).  They are not presented in the technical manual.  I have now computed those correlations, as well as a few others with the Wechsler GAI, and they are now part of the SlideShare at the link above and are also reported below.  Click on image to enlarge.
