Dealing with problems of environmental, economic and social concern emphasis is placed on developing learners′ interdisciplinary and action competence to participate actively in building more sustainable futures. Higher education is called to play a critical role in this process. This paper deals with a European Commission funded programme CLIMASP that aims to develop interdisciplinary minors in climate change and sustainability policy in 10 Middle-Eastern universities. In this chapter, we present the results of the pre-test and post-test surveys that were carried out during the piloting phase in the spring semester of 2014–2015 academic year. Our aim was both to test reliability and validity of learning models as well as to examine possible changes during the implementation process. The statistical analyses show that the instruments are reliable, although improvement and enrichment is possible as well as increased changes experienced by students at the end of the piloting courses.
