OCAA is one of many Associations which make up the NSW Teachers Federation. OCAA has over 500 Federation members. These members have been allocated to OCAA as their Federation association because they work at a non school based workplace in the Department of Education or NESA.
Like all associations, OCAA has elected representatives on the Federation's decision making bodies, including Federation Council and Annual Conference. There is also an OCAA Restricted Committee of five members elected by Federation Council every two years.
