Background and purpose: The interest in raising the competence of teachers through networks and network activities is increasing. This article is based on the voices of four newly qualified teachers who give us the opportunity to listen to experiences in authentic surroundings. The purpose of this article is to gain better insight into the type of networks newly qualified teachers maintain, develop and create to develop as teachers. The research question is: What is the importance of networks for the professional development of newly qualified teachers in upper secondary education? Main argument: The main finding of the article, based on in-depth interviews with four newly qualified teachers, is that being acknowledged by colleagues is decisive for professional development. Furthermore, the school's programme of meetings to some extent contributes to developing the respect and trust of the newly qualified teachers, who also need to find time and opportunities for reflection in personal networks outside school. The relational and emotional aspects of the teaching profession produce a need for guidance processes where the ethical dilemmas of the profession can be raised. When these dilemmas arise, the newly qualified teachers actively look outside school to grasp opportunities for professional development. The teachers appear to be very active in their own professional development, and they have ambitions to develop as teachers for the benefit of the pupils and the school. Conclusions: Systematic guidance is highlighted as fundamental for these teachers' learning.
