A board of trustees is a group of individuals who are charged with managing an organization, such as an educational or charitable institution, and working in the best interests of its stakeholders. The board typically consists of members from different backgrounds and professions, with a wide range of knowledge, experience, and expertise that can be drawn upon during decision-making processes. The board works to represent the interests of the organization’s stakeholders, and it is the board’s responsibility to ensure that the necessary decisions are taken and implemented to best serve the organization's mission and objectives.

Trustees can be compared to the board of directors found in a publicly traded company. Both boards are responsible for making decisions that affect the organization and holding people accountable, but while the board of directors is usually responsible for a public company, the board of trustees is typically responsible for the management of a private organization. The difference is that the trustees are not held financially liable if the organization fails, unlike the board of directors, who would be held personally liable in such an event.

The role of a board of trustees is critical for any organization. Trustees are responsible for ensuring that the organization carries out its activities in a responsible and ethical fashion, aligns its objectives with its mission and works to ensure the best outcomes for its stakeholders. Generally, boards of trustees operate at the highest level of governance, provide guidance, and ensure the interests of the organization and its stakeholders are upheld.

Trustees are typically elected to a set length of terms and can usually be removed from their positions if the organization's stakeholders feel the trustee is not adhering to the organization's policies or exhibiting any behavior that is disrepute to their position.

The board of trustees plays a critical role in the management and sustainability of an organization, as its members are responsible for upholding the organization’s values, goals, and mission, and for providing effective leadership to ensure an organization’s success. In addition, the board of trustees can be a valuable resource for making tough decisions, as the members of the board can leverage their individual experience and knowledge to provide insight and guidance within the organization. By working together, trustees can provide a variety of perspectives and ideas for problem solving affecting the organization and its stakeholders.
