After nearly half a century of authoritarianism characterized by Chinese nationalism and Mandarin promotion, democratization in 1990s Taiwan was accompanied by a Taiwanization movement featuring calls for the revitalization of local languages and the promotion of linguistic equality. To that end, the government began planning for local language education, and, starting in 2001, children have had to attend one weekly hour of mandatory local language education. This curriculum, which is often referred to as "mother tongue education" in Taiwan, has been criticized as being of little value for language acquisition and transmission. Squeezed between Mandarin - the language of instruction, public affairs and increasingly language of home--and English--the international language--the so-called Taiwanese mother tongues are increasingly being learned, taught and used as second languages. Based on a review of secondary sources, public document analysis and interviews with Taiwanese public officials and language revivalists, this paper offers an overview of local language education policy and planning in Taiwan, with a special focus on the respective influences of democratization, human rights promotion and identity politics.
