Wisconsin Card Sorting Test

The Wisconsin Card Sorting Test (WCST) is interpreted by analyzing many metrics, such as the number of categories attained, perseverative errors, non-perseverative errors, and failure to maintain set, and comparing them to normative data for the subject's age and educational level to spot any potential executive dysfunction or cognitive impairments.

To score the Wisconsin Card Sorting Test (WCST), categories attained, perseverative errors, non-perseverative errors, and failures to retain set must be counted and compared to normative data for the test taker's age and educational level.

The Wisconsin Card Sorting Test (WCST) should only be administered by trained professionals, such as clinical or neuropsychologists, who have expertise in administering and interpreting the test and are licensed or certified to do so in their respective jurisdictions.
