The SACE Board of South Australia is an independent statutory authority of the South Australian Government involved in educating and training students in senior secondary education. The Board sets the curriculum statements of subjects to be studied in years 11 and 12 and is responsible for the assessment of student achievement in these subjects. The Board issues the South Australian Certificate of Education (SACE) to all students who are successful in meeting the objectives of senior secondary assessment.

As an independent statutory authority established by Act of Parliament, the SACE Board of South Australia serves all members of the three school sectors: the Association of Independent Schools of South Australia, Catholic Education South Australia and the Department of Education and Children's Services. It also assesses the achievement of students in the Northern Territory and at centres in South-East Asia.

The SACE Board of South Australia is served by twelve Board members. The office of the SACE Board has a full-time staff of approximately eighty, who help schools and teachers to implement the Board's curriculum and assessment policies. More than 2000 people are also employed at various times of the year as members of curriculum committees, examiners, moderators and markers.
