Despite a more prominent role of arts education in the school curriculum, artistic creativity does not occur to a great extent in primary school practice. More opportunities for teachers to strengthen their know-how in the field of artistic creativity can therefore be considered important. Arts education projects focus on pupils' development of creativity by means of introducing artists with their divergent working methods into primary schools. Beside fostering pupils' creative openness and skills, arts education organisations aim to transfer artistic enthusiasm to teachers in each project. Collaboration with artists can encourage teachers' artistic creative work. New working methods, techniques or ways of experimenting are more likely to be adopted in daily teaching practice when the project duration consists of several years. However, most projects are short-lived and the means for a long-term project policy are limited. Consequently, results in the area of sustainable outcomes concerning artistic creative work with teachers are limited. To create a long-term view, the availability of financial resources is an important condition in order to realise a mentality change towards artistic creativity in education. Finally, continuing debate with several participants about making artistic creative work sustainable remains necessary.
