While writing is a critical part of the medical profession, longitudinal studies exploring the social apprenticeship and genre knowledge development of medical practitioners are almost nonexistent. Through interviews and writing samples, this article traces a 10-year journey of one writer’s engagement with the Patient SOAP note, following his experiences from the first year of his undergraduate education to the end of medical school. Drawing upon theories of social apprenticeship and the RIME framework (reporter, interpreter, mediator, educator) from the field of medicine, we offer an in-depth case study of our focal participant’s growing medical expertise as he masters the Patient SOAP note. Through this in-depth analysis, we argue that the SOAP note functions as a “threshold genre” to assist entry into the medical profession. We conclude by offering additional evidence about the role that key threshold genres play in the development of professional expertise and offer implications for genre theory.

虽然写作是医学专业的重要组成部分，但探索医学从业者的社会学徒和体裁知识发展的纵向研究几乎不存在。通过采访和写作样本，本文追溯了一位作家从本科教育第一年到医学院结束的经历，他与患者 SOAP 笔记接触的 10 年历程。借鉴医学领域的社会学徒制理论和 RIME 框架（报告者、解释者、调解者、教育者），我们提供了一个深入的案例研究，说明我们的焦点参与者在掌握患者 SOAP 笔记时不断增长的医学专业知识。通过这种深入的分析，我们认为 SOAP 笔记作为一种“门槛类型”来帮助进入医学行业。
