The recruitment and selection of high performing leaders and managers are central to the human resources strategy of most organisations. Numerous studies attest to the efficacy of combining both cognitive ability and personality assessment tools in selection, promotion and development as these yield high validity (Busato, Prins, Elshout & Hamaker, 2000; Lievens, Harris, Van Keer & Bisqueret, 2003; Roberts, Kuncel, Shiner, Caspi & Goldberg, 2007).
A recent South African study looked at two ability and personality assessment tools, the Swift Analysis Aptitude-R and the Wave Professional Styles to evaluate the extent to which these were able to predict managerial performance. The study found significant relationships between these assessment tools and how managers performed their jobs.
