At SMU, 58 per cent of students have done between two and six internships, when they are required to fulfil only one 10-week stint. An SMU spokesman said that the University has seen a 40 per cent increase in the number of students going on more than one internship over the last three years. NTU said that it does not track the number of stints students do beyond internships that carry credits for their graduation. At least half of NUS' students have done work stints, although it does not track the number of internships they take part in.
