The Australian Tertiary Admission Rank (ATAR) is a numerical measure used to assess a student's academic performance in their final years of secondary education. It ranges from 0 to 99.95 and is calculated based on a student's results in their Higher School Certificate (HSC) or equivalent qualifications. The ATAR helps universities determine eligibility for admission into various courses. The ATAR is not a score that students can achieve directly; rather, it is derived from their subject results and is designed to rank students relative to their peers. A higher ATAR indicates better performance, making it easier for students to gain entry into competitive university programs.
