Project-based learning methodology has been applied in a technical education Master programmes over almost the last almost nine years. The major results that have been achieved are that the graduated students have acquired a wide range of knowledge, together with deeper theoretical and practical skills in specific topics, and the effective enhancement of their analysis skills and training in constructive opposition to the examination of the research work of other groups. The main conclusion is that the course final written examination is not the only reliable examination form for judging the understanding of students. Project-based learning methodology provides a continuous examination of the gradual understanding of students instead of a final written examination.
