ABSTRACT
This chapter provides a more direct stance in defending the use of dimensions in assessment Centres (ACs) as measures of important skills and abilities. An assessment centre (AC) is a standardized evaluation of behaviour based on inputs from multiple assessment methods. The source of much of the momentum behind the move by Lance to reinterpret the historical pattern of AC results is a series of meta-analytic reviews that summarized the convergent and divergent validity from AC post exercise dimension ratings (PEDRs) over the last 30 years. The design features that have been shown to have some impact on the convergent and divergent validity of assessment centres are by now well known. The developmental ACs on which these data are based relate to the High Performance Behaviour (HPB) leadership competency model. The HPB model contains some dimensions of leadership behaviour, and was developed based on a qualitative review of the academic literature on effective leadership behaviour.
