Until the end of 2019, CBM operated as a federation with 11 member associations worldwide and its own program-implementing umbrella organisation (CBM International). In 2020, CBM International was united with the German member association to form the CBM Christoffel-Blindenmission Christian Blind Mission e. V. (CBM) to strengthen the effectiveness and efficiency of the worldwide program work.
Until December 2019, CBM served as a global network of 11 member organizations and its own supporting entity, CBM International. In 2020, CBM International merged with the German branch to create the revamped CBM, focusing on enhancing international program effectiveness.
