A NEW era of expansion awaits Lingnan College as the tertiary institute passed its 25th year milestone with 400 graduates emerging from its 23rd graduation ceremony, recently held in the Queen Elizabeth Stadium. Governor Mr Chris Patten, Visitor of the College, officiated at the ceremony which was attended by families and friends of the graduates. Mr John Chen, the college president, told the audience of the most significant development in prospect - the move to a new campus in Tuen Mun in 1995. The site - at Fu Tei - is situated near the Tai Lam Country Park. ''This ambitious project will distinguish Lingnan as the only fully residential local tertiary institution,'' Mr Chen said. ''It will not only save the students' commuting time but also help them develop a sense of sharing and community, and encourage their personal growth and their commitment to social service.'' While the Government will provide funds to build a functional campus and hostels for 750 students, the college still needs to raise over $230 million to house 1,250 students and build an auditorium. Lingnan College has made landmarks since its inauguration in 1967. From a private school, it became a post-secondary college and then a degree-conferring tertiary institution in November 1992. By 1994-5, the whole of the college's study programme will be at degree level. Meanwhile, Lingnan is designing four new streams: Public Policy and Resource Allocation, International Political and Legal Affairs, Company Secretaryship and Administration Studies and Human Resources Management. ''Moreover, we will start offering postgraduate programmes in Social Sciences and Translation in 1995-6, and in Chinese and Business in 1997-8. All these developments represent significant steps forward,'' Mr Chen said. Early this year, the institution also upgraded its staff by creating its first professorship. It plans to appoint three more next year. Lingnan has now become a member of the Association of Commonwealth Universities, but at the same time it has extended its academic links with those in China.
