This text deals with moral values at school and their implications to the formation of teachers. It will therefore discuss briefly and at first what moral or ethical values are, and how the school may position itself with regard to them. Some observations related to teacher's values and the practices engendered by them will then be presented. Comments are made on the results of a research that illustrates the transmission of values in an indoctrinal manner, and the civic and moral education as carried out during the military dictatorship, and, on the other hand, the relativistic and/or laissez-faire position certain schools can adopt, in methodological terms, with respect to the education of values. Finally, the text will defend the idea that a discussion about values is necessary among the several members of the school, leading to a methodological choice to teach both the teachers, in their continuing education, and the pupils. Jean Piaget's theory of moral development will be presented as a possible reference to the education of values. Examples of situations of conflict of values at school involving the management, parents and pupils will be discussed to illustrate how a school can adopt a democratic procedure in the education of values, which presents itself as a possible third path in the education of values at school, beyond indoctrinal or relativistic positions.
