Training is one of the main goals of ITA, since its origins; nevertheless this activity is actively developing during the last couple of years. ITA has been involved in the preparation of Master course for some years and is developing a “University network”. ITA is also organizing training courses for Young Professionals at the occasion of the World Tunnel Congresses, since 2005. ITA also organizes at the demand of its members workshops and symposium on specific topics. Finally ITA will now deliver a didactic form for all the publications of its WGs.
