Following the integration of GIS into the national curriculum standards of senior high school geography, Taiwan has systematically implemented GIS education for over a decade. However, the effectiveness of this implementation is currently unclear. Therefore, this study investigates the status of GIS education in Taiwanese senior high schools. A nationwide questionnaire survey and ten personal interviews were conducted between 2009 and 2010. The results indicate that approximately 99 percent of teachers are confident to teach about GIS. The current educational strategies of promoting GIS have proven effective and shall be continued and expanded. (Contains 6 tables and 5 figures.)
