Abstract This study is based on a curiosity about the language education policy and its background after Taiwan’s liberalization in 1987. Suggestions based on the study results are made with an aim to providing some references for any future language policy and other relevant researches. Theoretically, I begin by analyzing the value of social linguistics and the concept of multi-cultural education. I then explain the target of the language development plan as well as the possibility of bilingual education (mother tongue and English). Tracing language development in Taiwan, I tried to collect more information on Taiwan’s language policy after the liberalization, together with the global language development trend. After Taiwan’s liberalization, language education in schools, foreign language education, overseas Chinese education and immigrant language education have become the main themes of Taiwan’s language education policy. With limited time and capability, I can only focus on the segment of language education in schools, to analyze the contribution and influence of Taiwan’s language education policy. The information in the documents is expected to present a dynamic feature of Taiwan’s language education policy including the determining factors, organization, language choices and planning. This study has divided Taiwan’s language education policy into two stages with two significant elements: Stage 1: 1987-2000, multi-dimensional rapid development; stage 2: 2001-present, stabilized, in-depth development. Finally, based on the study results, I make some suggestions for those who are in charge of language education policy designation, language choice, and those social revolutionists, hopefully to enhance the language education in Taiwan.
