Ethical formation is a preparation for the professional world of Veterinary Medicine and Animal Husbandry in which the University, besides preparing good professionals, is also committed to build citizens with ethical competences thus contributing for their professional decisions to be based on moral principles, and strengthening their critical capacity so that they can act responsibly. Veterinarians and animal husbandry professionals frequently find in their professional practice a diversity of moral situations where the wellness and the balance of society and the environment are at stake. From these contexts, the ethical level of the sampling groups, according to the stages established in the scale of moral judgment described by Lawrence Kohlberg, was analyzed. Through a descriptive methodology a series of dilemmatic exercises was performed in which students and graduate students were confronted on a scale of hypothetical problems that classified them in the stages of moral development explained by Kohlberg. The evaluation was conducted with three groups of Veterinary Medicine and Animal Husbandry students attending different semesters (Start, mid-career and last semester) and a survey was applied to a group of graduate students. It was concluded that students of all academic semesters and graduate students are located, in higher percentage, in conventional and post conventional levels, with some variations depending on the typology evaluated and the academic level of the learners.
