Sixty undergraduates of five-year program enrolled in 2015 in Harbin Medical University who was taking clinical probation from February in 2018 to January in 2019 were selected as the research objects. The students were randomly divided into control group and experimental group distributing with 30 in each. In clinical probation teaching, Mini-CEX evaluation method was used in the experimental group and traditional evaluation method was used in the control group. After the probation, comparing two groups for clinical diagnosis and treatment, and collect the comment from experimental group about students' satisfaction about Mini-CEX evaluation. Results The scores of medical history inquiry of experimental group and control group were (7.77 ± 0.82) and (7.10 ± 1.21), respectively; The physical examination scores were (7.40 ± 0.81) and (6.83 ± 0.99) respectively; The scores of humanistic care were (7.30 ± 1.12) and (6.07 ± 1.89) respectively; The clinical judgment scores were (7.47 ± 0.86) and (6.77 ± 1.48) respectively; The scores of communication skills were (7.77 ± 0.86) and (6.93 ± 1.53) respectively; The scores of organizational effectiveness were (7.20 ± 0.61) and (6.57 ± 1.10) respectively; The overall performance scores were (8.13 ± 0.68) and (7.40 ± 1.19) respectively; The differences were statistically significant (all P<0.05). The questionnaire results show that 93.3% (28/30) of the experimental group students are satisfied with the Mini-CEX method. Conclusions The application of Mini-CEX method in clinical probation can improve the quality of student probation.
