This research intends to investigate the teacher selection process that candidates go through in order to become formal teachers. Narrative research has been used to understand a primary school teacher's motivation for being a teacher. By following the process of the teacher selection experience, the significance and effects of the teacher selecting experience on the teacher's expectations and career could be discovered. With the implementation of the "Teacher Training Law" and the phenomenon of Taiwan's low fertility rate, the path from teacher selection to formal teacher training has become even more challenging. The interviewee in the story acted as a substitute teacher for 7 years and has now become a formal teacher. By reflecting on and sharing his or her life experiences, he or she has acted as a reminder that teaching requires not only the professional skills of patience, communication, cross-curricular teaching, and bilingualism, but also the need to keep in mind the reason why one became a teacher in the first place. By doing this, educators could assist students in realizing their goals and aspirations.
