From the perspective of historical institutionalism, based on several critical junctures of the past half-century in China, this paper divides over 40-year history of China's teacher certification institution into four stages and elaborates on mechanisms and processes of critical junctures that impact even determine teacher certification institution reforms. The features of China's teacher certification institution are as follows: Its examination system is increasingly perfect; its direct accreditation depends more on graduates' quality rather than major categories; its history is a seesaw effect history between pedagogic and academic orientation of teacher education; teacher certification institution and normal specialty students' quality is the bottom line of teacher workforce performance under the open teacher education system; and the intersection between pedagogic and academic orientation of teacher education leads to the standardization and professionalization of teacher education in all respects.
