According to the European classification of skills, competencies, qualifications, and occupations (ESCO), transversal knowledge, skills, and competencies are pertinent to a wide array of occupations and sectors. Transversal knowledge, skills, and competencies are the foundational elements for developing the “hard” skills and competencies necessary for success in the labor market. In this paper, we introduce an online platform for assessing the attainment of transversal and soft skills. This tool allows us to define levels of competency acquisition and measure students’ development. The use of these competency levels helps improve the understanding of these skills and the evaluation process. The tool also enhances coordination among courses and teachers. The evaluation process can be established on three different levels: self-evaluation, peer evaluation, and teacher assessment. Developers, students, and teachers have assessed the tool has been developed following a lifecycle of evolutionary prototypes with successive refinements.
