摘要:AbstractTwo related researches are presented in this paper: the first study tested a predicting model of the job performance based on competency matching indices analysis, on a sample of 200 Romanian employees, while the second one analyzed the influence of three persistence factors on the job performance. Surprisingly, results showed that job competency matching index proved a low predictive power for the job performance, while two persistence factors seemed to be high predictive. These results might question the general assessment practice beliefs in the human resources field.
