The AISSA is an advocate for non-government independent school education and it also contributes significantly to improvements in education.
- Constituent interests are represented by a Board and Reference Groups of the AISSA, which comprise representatives from Principals/Heads, Governors of schools, school systems/groups and Bursars/Business Managers. This provides an opportunity for various groups to discuss and formulate policies and strategies to enhance the distinctive characteristics of independent schooling.
- The AISSA is committed to providing appropriate professional expertise and advice and to maintaining an extensive network with other education sectors, government agencies and community organisations.
- AISSA nominees are members of key regulatory and advisory bodies including:
- the Education and Early Childhood Services Registration and Standards Board of South Australia
- Teachers Registration Board of SA
- SACE Board
- National Partnerships Advisory Council
- At the national level the AISSA represents member schools on the Independent Schools Council of Australia (ISCA) which plays a key role in advising and lobbying Commonwealth politicians and government agencies.
- Staff from the AISSA Office and schools are members of committees that coordinate educational projects (eg, key competencies, national statements and profiles) and administer legislative requirements such as OHS&W, copyright, animal ethics and child protection.
- The AISSA also administers funds allocated to non-government independent schools under the Commonwealth's Targeted and Quality Teacher Program and the Capital Grants Program.
- There is a high degree of cooperation between the AISSA, Catholic Education Office and the Department for Education and Child Development in South Australia to ensure the common interests of the sectors are strongly presented.
