Objective To construct a framework and relevant evaluation items for evaluating the core competence of clinical nursing teachers. Methods We explored the whole frame of competence structure and established behavior items for evaluating competences with corresponding level-marking standards through theory analysis, literature study, expert consultation and a small sample test. We also investigated 237 nursing managers, teachers, and students from six medical schools in China using a 5-point Likert-type scale. Item analysis and factor analysis were performed to reveal competence construction and connotation, and the evaluation model for core competence of clinical nursing teachers were constructed. Results Content, structure and internal consistency coefficient were checked for validity. Cronbach＇s alpha of the total system was 0. 9109 and of each domain ranged from 0. 6064 to 0. 8474. Results of Split-half Reliability demonstrated that of total system was 0. 8765 and of each domain ranged from 0. 634 2 to 0. 8369. Conclusions The evaluation model for core competence of clinical nursing teachers is composed of three parts： competence domains, behavior items and their corresponding grade standards. Core competence of clinical nursing teachers consist of four domains：leadership ability, problem-solving ability, teaching ability and nursing ability, each of which contains several behavior items and corresponding four grades standards reflecting different abilities.
