Selected results from a study designed to characterize the difficulties teachers face when starting their careers are presented in this article.The analysis is organized around the following questions: What difficulties do new, inexperienced teachers face in the classroom?How do they cope with those difficulties and what type of response do they offer?The study was exploratory and qualitative in nature.The sample was comprised of thirty male and female teachers who work at high schools in Resistencia, Chaco (Argentina).Two semi-structured questionnaires were used.The most significant findings show these teachers cope with problematic situations, fundamentally within the framework of multiple informal learning processes generated in exchanges with experienced colleagues and in their own successful experiences in the high school context.
