In Romania, the implementation of computers in social-economic life is being carried out with a view to creating a national data processing system. Parallel to the construction of electronic data processing equipment, there is a sustained concern for the selection and training of computer specialists. This study examined a psychological testing selection methodology for intensive courses for analyst programmers, junior programmers, card-punch operators, and computer operators. A psychological test battery was selected for each group, based on a job analysis of each occupation. Factor analyses and correlations between test performance and occupational success were used to investigate the validity of the test batteries. An optimum psychological selection strategy of the data processing personnel was worked out. This strategy reveals the necessity of complex psychological approaches in which selection is but one stage, a subroutine of the whole employment procedure and efficient socio-professional integration of an individual.
