The Australian Tertiary Admission Rank (ATAR) is a numerical measure used to assess a student's academic performance in high school. It ranges from 0 to 99.95 and is primarily used for university admissions in Australia. The ATAR is calculated based on a student's results in their final year of secondary education, typically the Higher School Certificate (HSC) or the Victorian Certificate of Education (VCE). The ATAR allows universities to compare students from different schools and states. A higher ATAR indicates better academic performance, making it easier for students to gain entry into competitive courses. Each university sets its own ATAR requirements for various programs.
