For administrative purposes, four Celtic Affairs Working Groups provide the strategic and operational resources that deal with priority action items. Each Working Group Chair is a sitting member of the NB Celtic Affairs Committee and draws additional volunteer members from the larger Celtic community.
The NBCAC may form additional Working Groups as emerging operational needs dictate or redefine existing ones if no longer needed.
