Annotation	The clock-drawing test has achieved widespread clinical use in recent years as a cognitive screening instrument. A significant amount of literature relates to its psychometric properties and clinical utility. This review aims to synthesise the available evidence and to assess the value of this screening test according to well-defined criteria. A Medline and Psycho-Info literature search of all languages was done from 1983 to 1998. A brief summary of all original scoring is provided as well as a review of replication studies. Psychometric data including correlation with other cognitive tests were recorded. Qualitative aspects of the test are also described. The review concludes that despite significant variability in scoring systems, all studies report similar psychometric properties. The clock test thus shows a sensitivity to cognitive change with good predictive validity. (RH).
