Board of Trustees

Executive Board members are the trustees of the SPAB and directors of the Incorporated Association. They are responsible under charity law for governance of the SPAB, delegating management responsibility to the director and staff. The Board has up to 12 members, 8 of whom must be Guardians - one appointed from each of the Guardians’ committees. It can also co-opt additional members with specialist skills who become Guardians. The Board meets five times a year. Guardian-trustees and co-optees serve for three years. No member may serve for more than six years in succession. Guardian-trustees must step down once their Guardian tenure comes to an end. Honorary officers – Chair, Vice Chair and Treasurer – are elected by the Board.
