Abstract: Objective　To clarify the causes of the choice of professional diversion of undergraduate medical technology students enrolled in broad category in independent medical schools, in order to provide suggestions for the professional diversion policy of medical technology in universities.Methods　Twenty undergraduates currently enrolled in the School of Medical Technology of Tianjin Medical University who had participated in professional triage were selected for semi-structured interviews, and the Colaizzi phenomenological study data analysis method was used to investigate the causes for their choice of majors during professional triage.Results　Factors that contributed to the selection of the current major by the undergraduate students who participated in the interviews included their first-year comprehensive assessment score ranking, future major course difficulty, major employment prospects, family background, and interpersonal relationships during the school year.Conclusion　Major diversion plays an important role in students' personal development, quality improvement and ability cultivation. The current major diversion policy has problems such as students' blindness in major diversion, insufficient content of career planning courses before diversion, lack of flexibility in major diversion, and unreasonable enrollment ratio. In response to these problems, schools should enrich career planning courses for students involved in professional triage; schools can also give students a second chance to choose their majors after professional triage; schools also need to make a comprehensive plan for the size and enrollment ratio of medical technology colleges.
