Objective To evaluate the effect of hierarchical authorization and accumulative point system employed in selection and management of clinical mentors. Methods One hundred and eighty nursing students on clinical practice were assigned into a control group and an intervention group chronologically, with 90 in each group. Students in the control group were mentored by clinical teachers who were designated by head nurses, while their counterparts in the intervention group were tutored by teachers who were categorized into 3 levels of junior, medium, and senior according to their qualifications and teaching capacity, then these teachers were managed using accumulative point system. The effect was evaluated after 1 year of intervention. Results The scores of knowledge and operation tests, as well as students′ satisfaction with their mentors and practicing departments in the intervention group were significantly higher compared with the control group (P<0.01 for all). The qualified rate of completion of teaching task was increased from 96.83%（275/284） to 100%（289/289）. Conclusion Employing hierarchical authorization and accumulative point system in management of clinical mentors, can mobilize their teaching responsibility, initiative and creativity, thus to improve teaching effect and satisfaction of nursing students.
