ABSTRACT Purpose The aim of the study is to analyse the experiences of 7 students (4 girls and 3 boys) from different continents (Africa, Asia and South America) in Physical Education, in order to know to what extent, they have perceived racism. Their guardians also participated. All the students have experienced their compulsory schooling in Spain. Methods The research is framed under the theory of culturally relevant pedagogy. A qualitative approach is used in which three categories of analysis are established: (a) Perception of social discrimination; (b) Effect on self-esteem and emotional implications; (c) Learning limitations in Physical Education. Interviews with students and focus groups with guardians, where the data collection techniques are/were used. Findings & conclusions The results show how students have suffered covert racism in the classroom, specifically in Physical Education, observed in a diversity of behaviours and actions linked to the colour of their skin, their accent, their physical features and even their body odour. This, despite their subliminal acceptance of it, has generated frustration, powerlessness and diminished self-esteem, as well as a bad relationship with the subject. Guardians recognize the experience of these forms of discrimination and emphasize that racism still exists in society and in schools, and that there is a lack of mechanisms and procedures to eradicate it. It is essential to continue researching how to approach a teaching of Physical Education that moves away from any type of discrimination, but this article is already a first step in giving a voice to those who suffer from it.
