1. Certificates and complete transcripts of undergraduate and postgraduate studies
Please upload official certificates and complete official transcripts of your undergraduate and postgraduate studies. The back side of the transcript(s) should also be provided if it contains information on the grading system. Documents which are not in English should be accompanied by a formally translated version in English. If it is the policy of your institution that the transcript should remain confidential, please request your institution to send it directly to the HKU Graduate School.
For current undergraduate or postgraduate students: it is to your advantage to let us have a photocopy of the interim transcript showing the results of courses you have so far completed.
For qualifications obtained from HKU (except HKU SPACE): Certified certificates and official transcripts are not required. If you are a graduate, you are requested to upload a photocopy of the transcript; if you are a current student, you are requested to upload a photocopy of the printout of your examination results from the Student Information System (SIS) or your examination result slips.
