The
Universities Admission Index (
UAI) was used in
New South Wales and the
Australian Capital Territory,
Australia, as the primary criterion for entry into most undergraduate-entry university programs. It was a number between 0 and 100 (though those below 30 were not reported), occurring in increments of 0.05 and indicating the rounded percentile rank of a student who undertook the
Higher School Certificate or ACT Year 12 Certificate with a valid quantity and combination of units of study. It was replaced in N.S.W with the
Australian Tertiary Admission Rank (ATAR) in 2009.
