Abstract: Objective Discussion on the application value of a competence-based teaching mode in the teaching of prenatal ultrasound. Methods Eighty-seven people from a teaching hospital from July 2015 to December 2019 in the ultrasound were selected.Forty-five students in the experimental group were trained with a new model targeted at “post competence”, while forty-two students in the control group were trained on the traditional teaching mode. Results The theoretical and technical scores of the experimental group are higher than those of the control group.The total theoretical and technical scores of the students with working experience are higher than those of the non-experienced group.The total theoretical and skills scores of master candidates are higher than the undergraduate group. Conclusions The teaching mode targeting at“post competence” can achieve good results in prenatal ultrasound teaching.
