AGBIS is a registered charity (No 1108756) and company (No 0521716) limited by guarantee governed by a Board which meets at least once every school term. Board members are nominated by school governing bodies and serve initially for a three year period. The Board is advised by three committees: Training and Membership, Nominations & Governance and Finance. The Board is entrusted with the management of the Association and has absolute discretion in applying the funds in furtherance of the objects of the Association.

As one of seven Associations which are members of the Independent Schools Council (ISC), AGBIS has two seats on the ISC Board and a similar level of membership on relevant ISC committees. The Chief Executive and Director of Training also meet informally with their opposite numbers in the ISC Associations.
