Plurilingual competence or repertoire of languages refers to all individuals being potentially plurilingual. As plurilingual competence and language repertoires are individual, assessment modes targeted to the individual and localized to the context should be encouraged. This study explored and depicted the plurilingual profile of Italian Studies students (and thus student language teachers) in the Greek context through various modes. The role of the Italian language in this localized context was also explored and the language trajectory was attempted to be depicted qualitatively. The instruments used were the Language Passport, the DIALANG diagnostic test, the ECML 'Self-evaluate your language skills' tool, a plurilingual portrait (to make the language repertoire visible), and a short personal written narrative. It is mainly a qualitative study, and instances of multi-method research are also present. Moreover, the whole procedure contributed to incorporating plurilingualism and multiculturalism into language teacher education for student Italian language teachers in higher education.
