Why WJ IV™ and WJ V™ Scores Should Not Be Directly Compared

The WJ V is a significant revision of the WJ IV, not a renorming of it. Although many test and cluster names are preserved across editions, the changes in item content, test composition, cluster membership, administrator mode, and normative samples are substantial enough that the WJ IV and WJ V scores cannot be treated as equivalent.

WJ V Nonverbal: Development, Validation, and Interpretive Guidance

The WJ V Nonverbal (WJ V NV) was developed to minimize the linguistic demands of cognitive assessment while preserving the cognitive constructs measured by the original Woodcock-Johnson V Tests of Cognitive Abilities (WJ V COG).  The WJ V Nonverbal is intended to support equitable assessment practices for individuals whose performance may be affected by language-based barriers rather than limitations in cognitive functioning.
