European Credit Transfer and Accumulation System

The European Credit Transfer and Accumulation System (ECTS) is a standard means for comparing academic credits, i.e., the "volume of learning based on the defined learning outcomes and their associated workload" for higher education across the European Higher Education Area (EHEA). ECTS credits are awarded for successfully completed studies, with the basic definition being that one full time academic year corresponds to a total of 60 ECTS credits; typically this corresponds to an annual workload of 1,500 to 1,800 hours, although this can vary as defined by national regulations.
