Levels of indicator development for education for sustainable development

The article summarizes some considerations about the development of indicators for education for sustainable development (ESD). It reflects the present state of discussion, especially from a German perspective, and includes present developments in the area of quality criteria and standards for ESD. These discussion threads only denote the beginning of a discourse that will eventually lead to a practicable instrument for estimating the progress of ESD. This article shall give suggestions for the systematic development of an indicator system for ESD linking three dimensions: levels of educational systems, key functions of indicators, and key aspects of indicator development.
