Internationalisation in higher education was primarily defined as the process of integrating an international, intercultural or global dimension into the purpose, functions or ways of delivery of tertiary education (Knight, 2003). Hence, internationalisation can be assumed either as a response to globalisation or as an agent of globalisation itself. In this context, the internationalisation of teacher education, which is considered a sub-field in teacher education, seems to derive from international/global education in general and particularly from the internationalisation of higher education (Koh et al., 2022). It emerges together with the recognition of teaching as a cosmopolitan work and profession amidst critical and economic relations to flows, contexts and consequences linked to the globalisation of dimensions centred on economy and culture (Luke, 2004). Apparently, the internationalisation of teacher education has become imperative in the last decades, with important global players in education, such as UNESCO and the OECD, devoting themselves to developing and endorsing policies to enhance education and societies (Sieber & Mantel, 2012). Obviously, while internationalisation is comprehended as a means to develop society as a whole, in light of an international competence that reveals to be critical to the cultural, technological, economic and political health of nations, institutions and individuals (Yemini et al., 2017), different organisations influencing its processes certainly detain varied, if not opposing, purposes (Sieber & Mantel, 2012). Within this scenario, more recently, the internationalisation debate has also shed light on a different nuance – the idea of internationalisation at home, i.e., the purposeful integration of international and intercultural dimensions into the formal and informal curriculum for all students in the scope of domestic learning environments (Beelen & Jones, 2015). Internationalisation at home is realised as promoting the development of international/global understanding and intercultural skills (Wächter, 2016) while equipping students with transversal competencies essential to thrive in a globalised world (Beelen & Jones, 2015). The approached theoretical framework is the basis of the project DITE – Diverse Internationalisation of Teacher Education, which focuses on the element of internationalisation (at home) to increase the capabilities of future teachers by sensitising Teacher Education students to international perspectives. The project network comprises six partners, namely, two networks specialised in the theme of internationalisation, and four higher education institutions spread over three countries - Portugal, Spain and Poland. In the project's first phase, an empirical study was led to explore the current state of the internationalisation of teacher education in the participating higher education institutions. In this communication, we explore the results of this study, organising how different stakeholders (course directors, teacher educators, students, etc.) conceptualise internationalisation and associated values, challenges, enablers and barriers.
