Hong Kong is traditionally an examination-oriented culture, a legacy of its Confucian heritage. Since the 1990s, the Hong Kong government has shown its determination to make a change to this deep-rooted examination-oriented culture with assessment for learning highlighted as an important aspect in the reform agenda.
