is not a standard in itself but a tool of the European Higher Education Area (EHEA) for making studies and courses more transparent and thus helping to enhance the quality of higher education. ECTS is the basis for all transfer of educational data since it defines words like credit (what workload should one credit be), courses, programs, levels and diplomas. It has resulted in the ECTS Users guide which has been adopted by Ministers for Higher Education of the European Higher Education Area in 2015 at the Yerevan ministerial conference. It is therefore the official Guide for the use of ECTS.
