The Maslach Burnout Inventory (MBI) was projected to evaluate the Burnout Syndrome in working people. This article analyses the psychometric behaviour (reliability and construct validity) of the MBI in a sample of 563 teachers, workers from private institutions of elementary, high school and college levels in the metropolitan area of Porto Alegre-RS. The factorial analysis identified three factors originally related to the three dimensions identified in the inventory: emotional exhaustion, depersonalization and professional accomplishment. The three factors explained in this study 47% of the total variance of the answers by the individuals subjected to MBI. All of them reached a satisfactory level of consistence, and the factor 1 (emotional exhaustion) and the factor 2 (professional accomplishment) could function independently. As for the factor 3 (depersonalization), in the present study it is used in an explanatory level, contributing to a wider understanding concerning the configuration of Burnout in teachers.
