In this paper, we propose a methodology to support the Curriculum Design and Development (CDD) process with the aim of aligning competences provided by Higher Education Institutions (HEIs) with the ones required by companies. The proposed methodology stems from the identification of companies' training needs and aims at classifying a set of specific competences that are derived through a desk analysis of the existing academic offer. The novelty of the proposed methodology is represented by the introduction of quantitative indicators used for competences' classification which may support decision-makers in the individuation of the expected learning objectives of the curriculum. The proposed approach has been developed and tested in the context of a European Project (TrainERGY -- Training for Energy Efficient Operations) involving four European countries (Italy, Poland, UK and Greece), whose objective was the definition of a transnational curriculum oriented to qualify better practitioners involved in energy efficiency operations in SMEs.
