Only 15 per cent of Open University students are awarded a degree because the institute is determined to ensure the quality of its graduates was recognised, according to its president. Professor Tam Sheung-wai said that since the Open University was set up in 1989, more than 120,000 students had been admitted. However, only about 18,000 had obtained degrees, he told an RTHK programme. He said tuition fees were 10 to 15 per cent higher than at other universities because it received no government subsidies. He said his demand that public money be pumped in had been rejected.
