The process of personal development implies valuing critical-reflective work on the practices carried out and the experiences shared. And it is from this perspective that this research is taking place, which could lead to better reflections on internships and proposals for improvements. For this reason, the reflections of this research aim to report on the conception of students and school management about the presence of trainees in the maths subject and what relevance these conceptions had for the trainees during the course of their internship. It is also hoped that it will contribute to reflecting on the relationship between the initial training of maths teachers, their inclusion in the school community and the expectations of this community.
