The aim of this paper is to examine the relationship between transformational leadership and work satisfaction, as well as to analyse the mediating role of group identification and work engagement in a police training process at a Chilean professional military institution. The sample was made up of 985 candidates representing all the candidates that joined the units of the country in the different locations. Officers and non-commissioned officers acting as instructors were considered leaders', while their followers' were the young candidates in the training period. It was found that all the relevant variables were positively and significantly interrelated, and a model of structural equations revealed that both work engagement and group identification played a mediating role in the relationship between transformational leadership and work satisfaction. ResumenEste trabajo estudia la relacion del liderazgo transformacional con la satisfaccion laboral, y analiza el papel mediador de la identificacion con el grupo y el work engagement dentro del proceso de formacion policial en una institucion de caracter militar. La muestra estuvo compuesta por 985 participantes y constituye el total nacional de los funcionarios que se incorporan semestralmente a las diferentes reparticiones. Se considero como lider' a los oficiales y suboficiales que ocupan el cargo de Instructor' y a los jovenes en proceso de formacion policial, o Aspirantes a Carabinero', se los considero como los seguidores. A nivel descriptivo se demostro que todas las variables incluidas se relacionan entre si de manera significativa y positiva. A traves de un modelo de ecuaciones estructurales se comprobo que tanto el work engagement como la identificacion con el grupo ejercian un papel mediador en la relacion entre el liderazgo transformacional y la satisfaccion laboral.
