The Woodcock-Johnson IV (WJ IV)

A comprehensive assessment system on the cutting edge of clinical practice.

The Woodcock-Johnson® IV (WJ IV) system is structured to offer the ease of use and flexibility that examiners need to accurately evaluate learning problems for children and adults in a way that no other assessment solution can.

Facilitate exploration of strengths and weaknesses across cognitive, oral language, and academic abilities
Batteries can be used in conjunction with one another or as standalone assessments
Clusters engineered to provide the most diagnostically useful interpretations
Simplified and reframed procedures for evaluating ability/achievement comparisons and intra-ability variations
Expanded focus beyond the original broad CHC
theory that was the foundation for the WJ III®
