Each Woodcock-Johnson IV (WJ IV) test battery comes with a selective testing table, printed in the Examiner's Manual and Test Item Book, that lists which individual tests combine to form each cluster (for example, the Visual Processing cluster requires Test 7: Visualization and Test 14: Picture Recognition).
Examiners should review the selective testing table to determine what tests they need to administer to derive the cluster they are looking for.
For example, examiners seeking to obtain the Visual Processing cluster must administer WJ IV COG Test 7: Visualization and WJ IV COG Test 14: Picture Recognition.
