Versatile testing options

The WJ IV consists of three independent and co-normed batteries that can be used independently or in any combination, depending on an examiner's needs.

WJ IV Tests of Cognitive Abilities

Designed to place emphasis on the most useful identifiers for strengths and weaknesses in cognitive abilities through seven different broad CHC abilities, this battery captures Gf-Gc composite, Gwm clusters, and other scores for interpretation.

WJ IV Tests of Achievement

This battery is ideal for accurately screening, diagnosing, and monitoring progress in reading, writing, and mathematics achievement areas. Three forms (A, B, C) with parallel content provide the means to monitor progress two to three times per year.

WJ IV Tests of Oral Language

This new battery can help determine and describe a student’s ability to use expressive language. It includes nine English tests and three Spanish tests, all in a single easel.

“The WJ IV … allows practitioners to complete thorough evaluations using the same family of instruments. When I administer a battery that is less comprehensive, I complement my evaluations and test my hypotheses with the WJ IV.”
