The opportunity to build business and management skills or deepen knowledge in a specific area - and in the process increase job prospects in today's highly competitive workplace - propels many people towards postgraduate education. A perennial favourite in Hong Kong is the Master of Business Administration (MBA), with variations on the theme offered by dozens of local and overseas institutions. However, diversity is the hallmark of the times. As Kenneth Young, dean of the Graduate School at the Chinese University of Hong Kong, said: 'This relates to the economic downturn and changing social needs where good jobs are difficult to find and the knowledge explosion means things get outdated so quickly. These days, even people who already have good jobs know they have to keep on learning.' Business may dominate the postgraduate market but there also numerous options for the advancement of knowledge in other key areas of life in Hong Kong, from education and health and to a greater understanding of the mainland. Meanwhile, traditional academic subjects such as history and philosophy appeal to those who value advancing their knowledge for no worthier cause than for its own sake. The South China Morning Post's first Postgraduate Guide embraces all these interests, designed to help readers make the best choices.
