Jzioquitarrak is the name given to the participants in EuskarAbentura expedition:  125 youth aged 15-17 and original from the seven Basque territories plus the diaspora.

In order to participate in the expedition, they must submit an application (personal project + video presentation) and pass a selection process. Projects must deal with one of the three themes proposed each year by EuskarAbentura, and can be carried out in six different formats (historical, literary, audiovisual, musical, plastic or digital), respecting the requirements detailed in the registration bases.

Applications will be evaluated on the basis of originality, style, technique and quality. The jury is composed by members of Eusko Ikaskuntza and PuntuEUS Foundation.

The top 125 projects will get a place in the expedition. As well as the quality of the application project, the gender, origin and sociolinguistic reality of the candidates will also be taken into account, in order to form an expeditionary group that will reflect the diversity of the Basque youth.
