The schwelle Foundation's board of trustees is at the centre of the foundations decision making body.

Board members decide over resource allocation, sponsorship, support of new projects, and chair the jury of the foundation's Bremen Peace Award. The board of trustees is formed out of the executive committee and other people. Together, they appoint new members to join their board of trustees. 

Currently, the board of trustees consists of 16 members, out of which five are part of the executive committee and two are counsellors.
