Staff at the National University of Singapore (NUS) are not allowed to have intimate relationships with an undergraduate student, even if it is consensual.

According to the university's code of conduct for staff, found on the NUS website, the rule also extends to graduate students or any other student over whom the staff member "exercises or expects to have any pedagogical, supervisory or mentorship responsibilities, including, but not limited to, course teaching, examining, grading and advising".
