Many educational systems worldwide are making substantial efforts to integrate an international dimension into local schools, fostering significant changes in the processes of instruction and learning as well as transformations at pedagogical and organisational levels. In this paper, we analyse data collected in four schools in Israel that the local press and educational authorities have acknowledged as schools that prominently and comprehensively incorporated international, global and intercultural dimensions. We employ a case-study approach based on interviews with principals and teachers; analysis of schools' websites and documents; and on-site observations, in order to analyse the expression of internationalisation, understand who is involved in the implementation process, and stimulate thinking about the broader impact of this process.
