The College is a national professional membership association for educators. It has eight Branches - located in each state/territory - and approximately forty regional groups. While virtually all work at Branch and regional level is conducted on a voluntary basis, there is a national office in Melbourne that operates under the leadership of a full-time Chief Executive Officer.

The College is a not for profit organisation and operates as a company limited by guarantee. In 2008 the Constitution was amended implement changes to the structure, incorporating:

The ACE Board is responsible for the governance of the Australian College of Educators. Members include the National President (Chair), the National President Elect and/or the Immediate Past President (the latter for one year after the term as President has elapsed) (Deputy Chair) and three state presidents. The Board has the power to co-opt outside expertise, especially in the area of finance and business.

The National Council is a forum for debate and communication with the responsibility for ensuring the interests of members at State level are considered in planning and decision making. It will also be consulted in shaping the future directions for the College in the interests of Members. Members of the National Council include the National President, National President Elect and the eight state/territory Presidents. Two State Presidents are selected from amongst the eight Presidents to act as the Chair and Deputy Chair of the National Council.

Regional Committees are responsible for promoting the College goals by providing strategic activities and initiatives for members in the local area. Regional Committees normally have about 5 people under the leadership of a Regional President. Regions are established by the ACE Board.

The National Awards Committee has responsibility for judging nominations for the College Medal and College Fellowships. The College Medal is an annual award designed to recognise an outstanding contribution to education at any level and in any field. Fellowship is another award designed to acknowledge excellence in education. It is not a reward for service but in recognition of a distinctive contribution to the advancement of education. Nominations for the College Medal and College Fellowship are sought from Branches by the end of September of each year.
