Frequently Asked Questions

  1. Do I need to sit for the DET? / Can I be exempted from the DET?

    You will be notified via your Offer of Admission Letter or by your Faculty Administrator whether you are required to sit for the DET. The DET is held in July and January before the start of each semester and registration for the DET will be held around 3 weeks before the day of the Test. Students who are required to sit for the DET will receive an email notification from the Registrar's Office to register for the Test when registration opens.

    For matters regarding exemption, please contact your Faculty Administrator.

  2. I am unable to make it for the coming DET. Can I sit for the next one?

    If you have been informed to sit for the DET, please note that it is a university-level requirement which must be fulfilled before graduation. Based on your DET result, you may also need to read and complete additional Graduate English courses (GEC) during your study at NUS. As such, we do not advise you to postpone sitting for the DET as your study / graduation schedule may be affected. You should also check with your Faculty Administrator on the faculty's stand regarding this.

    If you have weighed the pros and cons and/or have your faculty's approval to sit for the next DET, simply register for it during the relevant registration period.
