Abstract

Talent Management is essential within an organization, its success or failure depends on its collaborators. Reliability, validity and security on the interpretation of its results are essential to make decisions about talent and statistics is the ideal means to provide it. In this study, the statistical methodology applied in psychometric and educational evaluation is adapted for its analysis. Evaluate the reliability and validity of the instrument used to evaluate using Cronbach´s and Spearman Brown´s Alpha tests; detect evaluation differences among evaluators using Mood test, which indicates the need to empower evaluators on how to evaluate. And the detection of the influence of the sociodemographic variables on the assigned scores, which made it possible to see the need to design a scale to objectively categorize the performance of the evaluated workers on the horizontal axis of a nine-box system. Leads to the conclusion that the credibility it gives to the performance evaluation is significant.
