This chapter was inspired by SALTO report (Bortini and Behrooz in SALTO Youth, 2012). The work presented ‘working’ definition of intercultural competence, focused on theories of acculturation and emotional-cognitive processes involved in the creation and preservation of the bias of intercultural skills approach. The process of the development of basic skills such as: coping with insecurity, critical thinking, tolerance of ambiguity, communication were described. The review of the literature and some applications of this subject were presented as a step to use them in everyday practice. Having a framework of intercultural competence such as these presented and discussed above, it can be helpful in ensuring a more comprehensive, integrated approach in everyday work and life and promoting a better cross-cultural dialogue.
