Ability, Demographic and Personality Predictors of Work Success

Abstract

794 working people aged around 30 years completed three intelligence (Ravens Progressive matrices: GMA Numerical and GMA Verbal) and one personality test (16PF) before entering jobs in public service. They were all graduates and there were various sex differences on all measures. They were rated by supervisors each year after they joined the organisation and data were kept on their promotions. Correlations between individual difference factors and the rated criterion scores showed many significant patterns. A series of multiple regressions entered demographic factors (sex, age, social class), arts vs science background, impression management, intelligence test scores, and the personality variables. A mean rating score as well as three years supervisor ratings and number of promotions acted as the criterion scale. Whilst there were some differences between the different criteria, there were some consistent findings. Gender was a consistent predictor whilst there were relatively few personality and ability correlates. Limitations are acknowledged.
