Model-Driven Engineering (MDE) is changing the way we build, operate, and maintain our software-intensive systems. Several projects using MDE practices are reporting signi cant improvements in quality and perfor- mance but, to be able to handle these projects, software engineers need a set of technical and interpersonal skills that are currently not widely available. The MDE postgraduate diploma intends to ll this gap by o ering a full-time one year formation on MDE. The course syllabus is designed to teach students how to work at a higher abstraction level by the rigorous use of (software) models as the main artifacts in all software engineering activities. Contents include the conceptual framework of MDE plus all techniques and tools (e.g., for de ning modeling languages, models, model transformations and so on) required to successfully complete software engineering projects following a MDE approach. The organizational impact (and challenges) of adopting MDE are exempli ed using real industrial experiences. This paper describes the MDE Diploma and the lessons that we learned after completing its first edition.
