This study consists of a survey that was performed over ten years, between 2000 and 2010. It aims to present concrete data regarding Chinese teachers' views on and satisfaction with Taiwan's Chinese teaching environment at university language training centers and private language schools. Three questionnaire surveys were conducted in 2000, 2005 and 2010. The purpose of these surveys is to compare changes in the teaching environment over time and provide a record of Taiwan's Chinese as a second language teachers' situation at the beginning of the 21st century.The results show that these Chinese teachers were most satisfied with the various aspect of their working environment in 2005, but their satisfaction rate showed a general decrease in 2010. This indicates that the working environment in Taiwan's Chinese language centers has made little progress during the last 5 years. This problem is worthy of further study and is in need of improvement.
