This study aims to examine the implementation of Taiwan's textbook selection policy. First, the literature in this study explores the background and the philosophy of this policy. Second, owing to English, the subject of the most editions in Taiwan, the public junior high school English teachers in Hsinchu City are surveyed to investigate their attitudes and considerations on textbook selection. Furthermore, by interviewing the stakeholders, a more comprehensive understanding can be gathered to represent the current situation and to expose the policy flaws. Finally, based on the conclusions of this study, some suggestions for improving the system of textbook selection are provided for the authorities concerned, schools, and teachers. Findings: 1. Preparation Phase (1) Textbooks are selected by teachers. (2) School administrative units help establish project teams and collect different textbooks. 2. Analysis Phase: 19.8% teachers do not read the books in advance that they will choose from, and the process of voting in some school is not secrecy. 3. Determination Phase (1) Inexperienced teachers are troubled with no usable evaluation sheets. (2) Most teachers highly concern about irrelevant factors, such as publishers' service. (3) Most teachers agree that yielding to group pressure is a serious problem. 4. Feedback Phase: Most schools lack a formal or systematical feedback system. 5. Related Influence (1) Some schools and teachers don't avoid conflicts of interest. (2)The prices of reference books, which are locked in the selected publisher, are rising rapidly. (3)To improve the quality of textbooks, teachers should provide their professional advice for the publishers to make up the deficiency of the Textbook Review System.
