The Communication des organisations program trains experts capable of playing a central role in the transformation of companies, local authorities, and non-profit organizations through communication. Positioned at the crossroads of information and communication sciences, social sciences, and management, this program offers an interdisciplinary approach to decipher the complex challenges of professional environments and to act accordingly. The Master’s program in Communication des Organisations is an interdisciplinary and career-oriented training that draws on the combined contributions of information and communication sciences, management, and social and political sciences. It prepares students to understand, reflect on, and lead communication in all its complexity within private, public, or non-profit organizations. Conceived as a strategic lever for action, communication is approached not merely as a tool for dissemination or promotion, but as a central function in the transformation of organizations, closely tied to issues of governance, legitimacy, change, innovation, and social responsibility. Offered as a work-study program, this master's degree anchors theoretical learning in the realities of professional practice. Students work in communication departments, agencies, local authorities, or institutions, and can immediately apply the knowledge acquired during the course.
