The psychometric properties of Pitcher Adjective Test, to assess leadership, were obtained. Participants were 400 health workers in the cities of Bogota, Cali, Bucaramanga and Barranquilla, in Colombia. By applying a logistic model, with difficulty and discrimination parameters, they were analyzed the properties of the items. The function of information of the test resulted more informative at the intermediate level (from -1.4 to 1.6), the indicators of difficulty and discrimination, were appropriate. A marginal reliability coefficient of.94 was obtained. Multiple correspondence analysis drew a two-dimension solution of leadership and by a latent class analysis, with a partial credit model, participants were classified into three leadership styles. According to this, it is concluded that psychometric properties are appropriate, and Pitcher Adjective Test is of interest, yielding a classification that does not correspond with those commonly used.
