The IEB is accredited by Umalusi, the Council for Quality Assurance in General and Further Education and Training, and serves as a recognised assessment body.

[1] The IEB was established in 1988, replacing the Joint Matriculation Board as an alternative examination body that was for schools not affiliated with state assessment agencies.

[2] Its main goal was to offer high-quality assessments to schools that supported non-racial policies, during a time when many independent schools wanted alternatives to state-run exam boards.

Initially focused on providing an inclusive examination option, the IEB has since expanded its role, now offering a variety of assessments that meet high standards and encourage innovative practices.

The NSC includes both continuous assessments—such as oral exams, practical evaluations, and portfolios—and a final summative examination.
