The aim of this mini-course is to show an approach to develop prospective primary teachers’ diagnostic competency. Every teacher encounters errors in their students' mathematical work. However, the identification, understanding and appropriate response to those errors is not a straightforward process. It requires a competency that is a crucial part of mathematics teachers' professional competence. During the mini-course, the theoretical background of the promotion of diagnostic competency will be presented and participants will be encouraged to actively participate in an error analysis teaching sequence. Finally, the characteristics of the activity will be discussed with the participants, considering theoretical perspectives and the challenges of initial teacher education.
