ROC Friese Poort has, together with 12 other European countries, developed an educational platform, where students from all countries can work together on tasks. The tasks are vocationally oriented and can be used in the different levels of the European Language Portfolio. The first effect of the platform was that students who will do their workplacement abroad could prepare themselves by making contact with students from the host country. Now Rainbow is used by students to learn a foreign language in direct contact with students in other countries.
