Tuning develops reference points for common curricula on the basis of agreed competences and learning outcomes as well as cycle level descriptors for many subject areas. This should enhance recognition and European integration of diplomas, taking into consideration the diversity of cultures.

During phase 1 and 2 (2000 - 2004), Tuning worked with 9 subject areas (Business, Chemistry, Earth Sciences, Education, European Studies, History, Mathematics, Nursing and Physics). In phase 3 (2005 - 2006) Tuning aims to encourage the use of the Tuning methodology and related tools and products (for example the model for determining student workload, the model for designing curricula and the model for organising and applying quality enhancement and assurance) in existing and new thematic Socrates networks as well as in other existing international networks and associations of subject areas.
