The toolkit is a set of instruments that seek to support HEIs, and in particular, their university staff and services (international relations office, student services, faculties, research departments, etc.) in their efforts to integrate or develop actions on issues related to migration and diversity through universities’ social responsibility. The challenge of this toolkit is to accompany university staff and services willing to engage in this process through a tailor-made approach, from their starting point to the objective that they have set for themselves. For this purpose, the Toolkit is conceived to offer users the possibility to navigate and narrow down the selection of tools according to their profile, needs and objectives.
