Senior Executive Team

The Senior Executive Team (SET) brings together the most senior leaders within UNHCR.

Drawing on their expertise in protection, operations and management, its members advise the High Commissioner on matters of strategic importance, both to support his decision making on high-level political analysis and to strengthen his capacity to provide strategic direction to the organization.

SET members share responsibility for the implementation of the decisions taken by the High Commissioner and play a critical role in supporting the overall institutional coherence and maintaining unity of purpose across the management structure.

The SET comprises the High Commissioner, the Deputy High Commissioner, the Assistant High Commissioner for Protection, the Assistant High Commissioner for Operations and the Chef de Cabinet. Additional senior staff members may be invited to join the SET to share their expertise on a particular topic of relevance. The High Commissioner chairs the SET and may request that it convene in his absence to deliberate on specific issues and to provide their collective advice for his final decision.
