Every two years, the International Week of the High School of Social Work (HETS) of the HES-SO Valais-Wallis brings together training and research partners, from Switzerland and elsewhere. During this one week, there are conferences, workshops and meetings organized allowing them to concretize their international agreements, to strengthen their collaborations, to exchange on their social work practices and to deepen the present stakes of the social work, particularly with regards to professional intervention and training.
