To be eligible for the award of a PhD, a student must fulfil the following conditions:

  • Obtain the total AU required for the completion of the programme within a period between the minimum and maximum candidature period stipulated for the programme.
  • Fulfil the course requirements for the degree programme.
  • Fulfil the minimum Cumulative Grade Point Average (CGPA) for graduation.
  • Complete thesis examination and oral defence for the PhD programme, and thesis examination for Master’s by Research programme.
  • Fulfil 50% of the total AU required with courses from their Academic College (for research programmes except Interdisciplinary Graduate Programme).

  • Satisfy all other requirements prescribed by the programme of study or School.

Curricular and Academic Unit (AU) Requirement

Doctor of Philosophy (PhD)

To graduate with a PhD, students must complete a total of 20 Academic Units (AUs).

Requirement TypeAUs RequiredGrading
Prescribed Electives (PE) (inclusive of any exemptions)12 AUsGraded (Included in CGPA)
Critical Literacy Modules8 AUsPass / Fail
Total20 AUs 

Important Note on Additional AUs: Any AUs taken beyond the required amount should be taken after your Qualifying Examination (QE) so they are graded as Pass/Fail. If taken before the QE, they will be graded and included in your CGPA computation.

 

PhD Critical Literacy Modules (8 AUs)

These modules are mandatory and graded on a Pass/Fail basis. They will be reflected on your official transcript (e.g., "Seminars 3 AUs Pass").

*Communications / Writing Training for PhD students

The courses will be Pass/Fail courses. Students can take any one of these courses to fulfil this requirement: Communications / Writing Training Programme | Graduate College | NTU Singapore. Students are encouraged to register for the Communication course early to secure a place, as class capacity is very limited.

Optional:  Should students need one-on-one tutoring/mentoring, they can schedule appointments with special tutors at LCC Communications Cube or NIE Grad Centre for individualised feedback on their writing and oral communication skills. 

Graduate English Requirement:
While not required for QE eligibility, Graduate English should be taken in Year 1, Semester 1. Clearing this early ensures you have the proficiency needed to read research literature, communicate effectively with your team, and draft high-quality papers.

English courses for postgraduate students – HWG703 (Graduate English)

Postgraduate students will be required to take and pass HWG703, unless exempted.

The School will inform new intake students to submit the HWG703 exemption form at the start of the semester.

Students who are not eligible for an exemption are required to register for HWG703 via GSLINK - Graduate Course Registration System during the Registration Period.

Enrichment Opportunities

All Postgraduate Research (PGR) students are encouraged to enroll in optional enrichment modules to build their transferable skills. Not Required for Graduation. Students’ Choices

Popular Options Include:

  • Scholarly Communication & Impact (Offered by NTU Library) – Counts as 2 seminars and can be counted in the requisite 40/26 PhD/MbR seminars.
  • Transferable Skills Series (TSS) (Offered by Graduate College) – Counts as 1 seminar and can be counted in the requisite 40/26 PhD/MbR seminars.
  • University Teaching for Teaching Assistants and other elective modules offered by CTLP.
  • Other Communications courses (Offered by LCC or other Schools/Colleges).
  • Internship
  • 3-Minute Thesis* (Submit entry).

*Note: 3MT remains mandatory for PhD students in COE

 

Important Notes on Enrichment:

  • Enrichment modules are not reflected on the official result transcript, though entities may offer certificates of participation/ completion. They will eventually be recorded in the NTU Achievements & Service Record (ASR) System when the system is ready for PGR.
  • If an enrichment module is graded, it must be taken after your QE so it registers as Pass/Fail. If taken before QE, it will affect your CGPA.
  • As the mandatory communication course is now 2 AUs, student can always take 3 AUs course to fulfill the 2 AU requirement.
