This study focuses on the second round of Taiwanese teacher preparation program (TPP) evaluation (2012-2017) to analyze how evaluation policy shapes TPPs. In-depth interviews were conducted with 13 stakeholders, which included professors, administrators, researchers, and staff involved in TPP evaluation. First, the findings revealed that neoliberalism influences evaluation policy and restricts the diversity of TPP development. Second, different evaluation approaches may be used to bring more inclusiveness and flexibility to evaluation standards. Third, evaluation plays an important role in TPP development, and a professional organization responsible for evaluation should be established in Taiwan in the future. To conclude, it is significant for TPP evaluation policy to consider policy ideology, evaluation standards, and program diversity to aid in improving the quality of teacher education not only in Taiwan but also internationally.
