The EORTC Board of Directors is the guardian of EORTC’s sustainability. The Board meets at least 4 times a year. It has strategic fiduciary responsibilities. It acts in good faith and for the benefit of the Organisation (duty of loyalty). It acts prudently with regards to the organisational resources (duty of care). It ensures legal compliance and non-engagement in illegal practices (duty of obedience). The board determines the Organisation’s mission, vision, and fundamentals. Therefore, it approves the EORTC global strategy inclusive of the scientific, operational, and financial strategies. The details of its functioning are regulated by a Charter. The Board of Directors is composed of the Chairs of the Board Committees and elected Members from the EORTC membership. The Board Committees represent multiple competences not only limited to sciences but also extended to fiduciary and fundraising expertise.
