The Wisconsin Card Sorting Test (WCST) has been widely used with many different patient groups. Recently, concerns for patient comfort, managed care, and tighter research budgets have encouraged both clinicians and researchers to use shorter test batteries. 

The new WCST-64™ uses only the first 64 WCST cards, thereby shortening the administration time for most individuals while retaining the task requirements of the standard version. 

The WCST-64™ also eliminates variability in the number of cards administered, facilitating straightforward comparisons of test-retest stability and comparisons of individual test results with normative and validity data. 

Features include: 

• WCST-64™ normative, reliability, and validity data are derived from the same samples described in the Wisconsin Card Sorting Manual-Revised and Expanded (Heaton, Chelune, Talley, Kay, and Curtiss, 1993).

• Individual WCST protocols were obtained and rescored for the first 64 cards administered. 

• The normative sample includes adults aged 18 to 89 years, as well as children and adolescents aged 6 to 17 years. 

• WCST-64™ raw scores with corresponding demographically corrected normative data for the WCST-64 variables are provided in the WCST-64™ Professional Manual. 

How do I upgrade?
If you already have the standard version of the WCST, just by purchasing the WCST-64™ Professional Manual, you will be substantially extending the clinical utility of the test.
