1979

In May 1979, the Independent Schools Board of Headmasters and Headmistresses in South Australia changes its name to the South Australian Independent Schools Board Inc. (ISB for short).

The membership includes all registered non-government schools, with Heads of schools acting as Board representatives. The South Australian Independent Schools Board Inc. offers 3 types of membership, with senior secondary paying more due to their complex needs:

• Membership: schools that offer Year 12;
• Associate Membership: Lutheran Primary schools; and
• Administrative Cover Schools: schools that receive general services from the ISB but are not part of decision-making.
