The trustees are responsible for the overall management of Addaction, its strategic direction and decision making. There are several subcommittees of the board:
- Resources committee
- Income and profile committee
- Service delivery and clinical governance committee
New trustees are provided with a thorough induction into their role through a meeting with the Chief Executive Officer and members of the Executive Team, at least two project visits in the first few months of their tenure and briefings from key members of staff on Addaction's work and their legal responsibilities as trustees. New trustees also sign an agreement that sets out Addaction's expectations of their role and responsibilities. All trustees undergo annual appraisals conducted by the Chair of the Trustees, who is in turn appraised by the Board of Trustees as a whole. Trustees are recruited in response to an identified skills gap following a rigorous external recruitment process. Being a trustee of Addaction is a voluntary role.
