Objective　To explore the application of formative assessment in clinical skills simulated training course. Methods　The clinical skills simulated training course for excellent doctors in our school was selected as the research focus

students of Grade 2014 adopted traditional summative evaluation (control group)

and the multi-station examination was used as evaluation method. Students of Grade 2015 adopted the formative evaluation on the basis of summative evaluation (experimental group)

a diversified evaluation system was established

including inter-group evaluation by students

random evaluation by teachers

feedback of operation videos of different stages and real-time feedback of students' opinions after class. Questionnaires were conducted among students and teachers at the end of the course. Results　The scores of the experimental group were higher than those of the control group

with differences being statistically significant (P<0.05). Questionnaires showed that the proportion of good selected by teachers and students in the feedback of formative assessment was markedly higher than that of just so-so and bad

indicating that formative assessment is conducive to increasing students' initiative for self-studying

improving students' learning effect

comprehensively and accurately evaluating students' clinical operational skills

as well as improving the teaching level of clinical practice skills. Conclusion　The diversified evaluation system

which combines formative evaluation with summative evaluation

has achieved good teaching results in clinical skills simulated training course and it is worth to be widely applied.
