The phenomenon of school dropout is perceived as a process that is caused by a variety of factors. Through a questionnaire, teachers in different academic functions (teaching and management) are surveyed to study their perception of school dropout factors at the secondary education level. Factors related to the student, school, family and commitment to learning were noted. According to teachers, the group of factors that most affect school dropout is related to commitment and support for students. In addition, statistically significant relationships between the different groups of dropout factors are verified, and no significant differences were observed between the responses of teachers with teaching functions and those with management functions. Various strategies for preventing school failure are proposed.
