Each WJ IV test battery comes with a selective testing table (see example below), that is listed in the Examiner's Manual and Test Item Book.

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.
