A new WJ IV Assessment Service Bulletin (ASB) is now available at the WJ-IV Riverside website. It is a free download. The description at the site is below. Click here to visit the page.
This bulletin provides a summary of the procedures followed in developing and validating the WJ IV.
Throughout the development and design of the WJ IV,
the test standards outlined in the Standards for Educational and Psychological Testing (American
Educational Research Association [AERA], American Psychological Association [APA], & National Council on Measurement in Education [NCME], 2014) were followed carefully.
Information in this bulletin is abstracted from the Woodcock-Johnson
IV Technical Manual (McGrew, LaForte, & Schrank, 2014) and is intended as an overview to highlight important aspects of the WJ IV
test design, reliability, and validity. Readers who are interested in more detailed information should consult the WJ IV Technical Manual.
ASB 1 (WJ IV Tests of Achievement Alternate-Forms Equivalence) is also available for download on the same web page.
