Comparing the effectiveness of verbal and numerical tests for predicting results of employees’ productivity

Abstract

This paper is devoted to the analysis of criterial validity for numerical and verbal tests widely used for the assessment, evaluation and selection purposes in human resourses. The research databse was compiled from two sourses, that is, testing data of employees from a broad range of companies, and criterial data from assessment centers. Criterial validity is a correlation coefficient between the resulting score and the indicator of work efficiency. The results show that tests on numerical and verbal skills are instructive and valid tools among other methods of human resourse assessment and selection. The link between the verbal test results and competences aimed at organising, learning and development has been found. The numerical test results were assossiated with such competences as goal orientation, learning abilities and development orientation. The results of both tests correlated to the results of competences related to problem solving and decision making.
