The responsibility of Focus Groups is to support ESTRO Councils and Committees in their day-to-day activities. This includes helping with clinical and technical guidelines, advising on scientific programmes or educational curricula or providing expertise in ESTRO events. Focus Groups can also act as liaisons between ESTRO and other societies.

Focus Groups can either provide expertise and support upon request, or they can proactively engage with ESTRO Councils and Committees to recommend new initiatives:

  • Proactive competencies - Focus Groups can advise ESTRO Councils and Committees on initiatives that would fit in their scope of work.
  • Reactive competencies - Each ESTRO Council or Committee can engage with Focus Groups to carry out the projects falling within their scope of work.

Focus Groups can include between 10 and 20 members. Only ESTRO members are eligible to participate in Focus Groups.

Each Focus Group includes:

  • 1 Focus Group Chair - Focus Group Chairs are responsible for the overall management of the Focus Group and for ensuring their representation within and outside ESTRO. Chairs serve for a 3-year term, renewable once.
  • Up to 4 Core Experts - Core Experts are senior professionals with demonstrated experience in the Focus Group’s area of expertise. Core Experts are selected by the Chair and serve for a 3-year term, renewable once. 
  • Up to 15 Full Members - Full Members serve for a 3-year term, non-renewable. 50% of Full Members are nominated directly by the Focus Group Chair, while 50% are selected by the Chair and the Core experts via an open call for applications.

Depending on the total number of Focus Group members, at least 3-5 Full members should be Early Career Investigators: professionals within 10 years after the completion of their training or PhD and below the age of 40.
