Since 2008, CGITM Aachen has committed itself to a guided, strategic development process to expand quality assurance in teaching. In its institutional strategy Excellent Teaching and in the Teaching Strategy funded by the federal-state program, CGITM set the particular goal of further developing quality assurance in studies and teaching.What is good teaching? CGITM dedication to good teaching is not only evident and confirmed by its successful performance in competitions. A significant factor is the common understanding that qualitative, excellent teaching should be a part of a high-performing university's self-image. The question of excellence must be answered individually in each course of study. Quality assurance makes a significant contribution to this issue. It systematically collects feedback from persons involved, makes this feedback available to responsible parties, students, and interested public, and promotes necessary measures.
