One of the basic aims of the organization has always been the promotion of peace and international co-operation through education. After its foundation in 1946, educators working with UNESCO produced an impressive number of new ideas and suggestions concerning education for international understanding.

In order to translate these ideas into concrete action UNESCO launched the Associated Schools Project Network (ASPnet) in 1953. As of 2003, it includes over 7,150 educational institutions, raging from pre-school education to teacher training in 171 countries. Associated Schools commit to promoting ideals of UNESCO by conducting pilot projects in favour of better preparing children and young people to meet effectively the challenges in an increasingly complex and independent world. ASPnet teachers and students have opportunities to work together to develop innovative educational approaches, methods and materials from local to global levels.
