Colin D. Elliott (1937-2016)

This article memorializes Colin D. Elliott (1937-2016). For 7 years, in his work as a school psychologist, Elliott studied the ability profiles of children with learning disabilities and the measurement of children's developmental stages. Subsequently, he trained school psychologists for over 20 years at the University of Manchester. In 1983, he made a major, enduring contribution to the field of psychometric assessment in both his home country and the wider field with the publication of the innovative British Ability Scales (BAS). An American version, the Differential Ability Scales (DAS), followed in 1990, and both versions of the test have been widely used and revised several times (BAS 2, BAS 3, and DAS-II). Many of his innovations in those tests have been adopted in other instruments. His other research and many publications focused on individual differences in children's temperament and personality and specific learning difficulties. Elliott moved to the United States in 1992 and was adjunct professor at the Gevirtz Graduate School of Education at the University of California, Santa Barbara. (PsycINFO Database Record
