In recent years, at both European and international levels, International Sign (IS) has gained increasing popularity, with more and more deaf people actively engaged in the international arena (EU Knowledge Centre on Interpretation). IS is a communication system that has evolved among deaf people who need to interact without sharing a common sign language. Unlike most pidgin languages with relatively simplified syntactic structures, IS incorporates many grammatical features typical of sign languages, such as spatial use, directionality, personification, and iconicity. This makes it more similar to a language than other pidgin systems (WASLI). Sign language users of different nationalities use IS to communicate in transnational contexts, both in work and social settings. Additionally, IS is increasingly used in the online streaming of events and meetings, allowing sign language users to participate in conferences and gatherings where interpretation is provided in various spoken languages (WFD). A significant part of the advocacy work carried out by the World Federation of the Deaf (WFD) and the World Association of Sign Language Interpreters (WASLI) is conducted through IS in international forums, making it the primary mode of communication in these settings. Since its first appearance at the WFD Congress in 1979, the demand for IS skills has consistently increased. However, there are no formal or informal training programs to learn and develop these skills, representing a significant barrier to the participation of deaf people in Erasmus+ and European Solidarity Corps activities. In the Erasmus+ Youth Programme (KA1) context, the primary communication language is English. To ensure the participation of deaf organizations, it is often necessary to provide interpreters for both the participants' national sign language and English. This process presents a challenge, as interpreters must be able to translate between English and the national sign language— a skill not always available, as sign languages are typically taught in relation to the spoken language of the country of origin. Furthermore, multiple translations slow down communication and increase complexity, with additional financial considerations. The main objective of this project was to bring together youth workers, youth leaders, and trainers—both new and experienced—who were already involved or interested in participating in international activities using sign language. The event served as a networking forum, facilitating dialogue on strategies to improve support for both emerging and experienced professionals working with deaf youth, while raising awareness of the sector. Additionally, the project provided support to deaf youth workers, deaf youth leaders, and deaf trainers with IS knowledge or those aspiring to acquire it. This facilitated the exploration and acquisition of knowledge about the Erasmus+ youth sector, which they could use in the future to participate more actively in international projects.
