To assist in resolving the perceived lack of transversal competencies (TCs) of engineering graduates by industry, this study investigates the characteristics of transforming an existing industry TC instrument for use in engineering education. The instrument consists of 36 nuanced sub-competencies with the corresponding definitions and descriptive mastery levels. This instrument was first used to determine required TCs mastery levels for BSc and MSc graduates by European industry and subsequently, using two representative curricula as case studies to map TCs course outcomes and lecturer perceptions of TCs course outcomes, using interviews for further exploration. The main findings are that the TC instrument is suitable to determine desired industry mastery levels as well as to map TCs course outcomes both in formal documentation and by lecturers. Also, a gap between the formal and perceived curriculum was found i.e. discrepancies in reported TC learning outcomes between formal documentation and lecturer-reported TCs in courses.
