The SKT is a simple and short test for assessing cognitive impairment of memory and attention. The test consists of nine subtests, each limited to a maximum performance time of 60 seconds. Thus, total testing time normally does not exceed 10 to 15 minutes. Test scoring and auditing are also accomplished within a short time and are easily learned. The test is useful for staging the severity of cognitive deficits and for assessing the benefits of therapy, especially with patients suffering from dementia. The SKT is highly accepted both by patients, who are motivated by the appealing character of the tasks and their play-like nature, and hospital clinicians and general practitioners (GPs) because of its brevity and simplicity. The SKT was introduced in Germany two decades ago and has been successfully validated. Test versions of the SKT in English and other languages have confirmed its international applicability and validity, a point of particular importance in light of the current attempts to harmonize methods for assessing the efficacy of pharmaceutical products.
