In the field of health practices, there are different models of health education. The objective of this article was to identify undergraduates' concepts of health education. This descriptive exploratory study used a qualitative approach. It was developed in the Undergraduate Nursing Courses of the Federal University of Santa Maria and Federal University of Rio Grande do Sul, Brazil. Subjects were undergraduate students of the last semester before graduation. Data were collected using a semistructured interview, and submitted to thematic content analysis. The results suggest that the undergraduate nursing students' training as health educators is permeated by concepts that are a mixture of traditional and modern assumptions on health education.
