Peer teaching is an effective educational approach for nursing students. It has been used in nursing as an adjunct to lectures and to support learning in clinical practice. This study evaluated the efficacy of peer teaching model which is used in skills training of student nurses. As an experimental study, it included 57 first years and 10 senior students from the nursing department. First years constituted the interventional group and the control group while seniors made up the peer educators. This study revealed that the experimental group students had obtained adequate skills in nasopharyngeal aspiration, permanent bladder catheterization practices and take blood pressure compare to their counterparts (p<0.05). The approach is helpful for improving students' ability in practical training. The study results add to the literature supporting the use of peer teaching approach in nursing training practical education.
