Policies vary widely: outreach and recruitment targets, preferences in admissions or hiring, and in some countries formal quotas or reserved places. The aim is to widen opportunity for groups that have faced discrimination and to make institutions more representative.
Examples include India’s system of reservations for historically disadvantaged castes and tribes, university admissions programs in the United States and employment equity laws in Canada. In 2023 the US Supreme Court ruled that race-conscious admissions at Harvard and the University of North Carolina violated the Constitution, which changed the practice at American universities.
