Preparing students in social work and occupational therapy to practice in a context of diversity is a major current challenge. However, little information is available on the consequences of fieldwork and the encounter with people with various reference frameworks on intercultural competence. The purpose of this study is to document the students’ perception of their practice with the Otherness during their fieldwork, the learning they think they have achieved and the changes they identify in their approach to diversity. Fifteen students from the French-speaking part of Switzerland wrote a practical account of a major event in connection with the intercultural encounter. The thematic analysis of the comments gathered illustrates how these internship experiences contributed to the process of transformation into a culturally sensitive practice.
