The Departments of Higher Education that have incorporated postgraduate courses in their curriculum must acquire provision and adaptability mechanisms so that the courses can correspond to the current and future needs of their students. Important factors, such as many disadvantages that the extremely competitive postgraduate courses abroad face, compared to the postgraduate courses in Greece, lead the potential students to choose the Greek ones. This research paper aims to find the right methodology for the postgraduate courses to attract more students. Specifically the research will be conducted through questionnaires, using Likert method and SPSS system for the processing of data. Our goal is to collect primary data from active postgraduate students of the Technological Educational Institute of Thessaly. The results of the research will serve as useful tools for the administrative members of both Higher Education Universities and Technological Education Institutes, as well for the teachers, since they can showcase the Greek postgraduate courses in comparison to the ones abroad.
