In line with the primary purpose of ISEI, to provide a framework and forum for professionals from around the world to communicate about advances in the field of early intervention, this symposium aims to discuss and raise issues related to the added value of international collaboration in early childhood intervention research and education today and in the future. It is informed by experiences of the EU-US Transatlantic Consortium on Early Intervention (EU-US Atlantis Programme, Excellence Mobility Project 2001-2013) and from collaboration in ISEI. Building on multilateral collaboration and agreements between universities and funding agencies, based on equal standards for quality we can share and learn from each other. By developing joint priorities building on the strengths in individual countries a common theoretical framework for research and education related to early intervention has been created guiding policy and practice.
