Data collected are analyzed by a psychometric model and a latent trait is found. Results are verified and validated. Moreover, external robustness is assured by comparing the Rasch Analysis results with other statistical methods. The purpose of this work is to measure the level of openness of managers through the Open MOOd Questionnaire. Which aspects allow us to identify different management styles, and if the openness characterises spe-cific clusters of managers. The study shows that the openness attitude in the professional activity of the managers is very high. the Open MOOd Questionnaire can be improved by considering some dichotomic items. The study highlights the model proposed identifies the Open Manager´s competencies, and identifies teaching methods for their develop-ment. The authors propose a new model to study openness. Diagnostic tools of consoli-dated statistical methods show that the Open MOOd Questionnaire is an effective tool to evaluate the openness.
