This paper focuses on the practice of writing in teacher training. The research was carried out from an autobiographical perspective, analysing records and reflections resulting from experiences in the school and university contexts. This analysis sought to understand the issues that were problematised and the knowledge that was built up through these writings. The aim of this work is to help recognise the formative potential of autobiographical writing, encouraging teachers to record their experiences and use this practice as an important tool for personal and professional growth.
