One of the priorities of the programme is to train doctoral candidates in teamwork and multidisciplinary collaboration, both within Spain and at the international level. This is accomplished by encouraging students to complete research stays at public and private research centres within Europe and around the world. Doctoral candidates who spend a minimum of three months at a renowned research centre or a higher education institution outside Spain are entitled to have an International Doctorate mention included on their doctoral degree certificate.

This activity involves a total of around 480 hours (three months). Research stays abroad may be completed at any stage over the three years that the programme runs.
