Peking Union Medical College (PUMC) launched the “4+4” Medical Doctor (MD) pilot program in 2018, admitting students with non-medical backgrounds from top universities, aligning with national medical talent training policies to foster diverse and eager learners in medicine. On the occasion of the graduation of the first class of the “4+4” MD pilot class at PUMC in 2023, we reviewed the teaching reform in the pilot program and carried out a systematic survey and interviews with students, faculties, and management staff of the pilot class. This article reports on the measures taken by the pilot class at PUMC in enrollment and curriculum setting, and demonstrates the achievements of the pilot class in terms of student academic background structure, knowledge acquisition and skill learning, scientific research ability, and course evaluation. The results indicated that the pilot class had met the national demand for the “Medicine + X” talent training model. More specifically, with a diverse academic backgrounds, the pilot class graduates had academic levels comparable to the eight-year medical education graduates, and their scientific research abilities were satisfactory. The pilot program at PUMC will optimize the curriculum setting, strengthen the construction of faculty, learning resources, and teaching facilities, and reform the academic evaluation methods, thus deepening the reform of medical education and improving the “4+4” MD program as a novel medical education model.
