Assessment centers have become widespread in Western Europe, Northern America,
and Australia (Newell & Shackleton, 1994). The Task Force on Assessment Center
Guidelines (1989) defined assessment centers as “a standardized evaluation of behavior
based on multiple inputs. Multiple trained observers and techniques are used. Judgments
about behaviors are made, in major part, from specifically developed assessment
simulations. These judgments are pooled in a meeting among the assessors or by a
statistical integration process” (p. 460).
