This study is to investigate the effect of CPR education on the knowledge, attitude, and self-efficacy of kindergarten, elementary, and secondary teachers. For the study, a total of 176 kindergartens, elementary schools, and secondary school teachers in J province who received CPR education at an Emergency Medical Education Center from March 21 to June 20, 2023 were surveyed. For the collected data, SPSS WIN 20.0 was used to analyze general characteristics, knowledge, attitude, self-efficacy, and educational program effects. As a result of the study, the knowledge score after education (t=-15.93, p<.001), attitude score (t=-5.11, p<.001), self-efficacy score (t=-12.52, p<.001) was significantly increased. After the education by experts, knowledge, attitude, and self-efficacy improved, and it is thought that the increase in knowledge increased attitude and self-efficacy. This is a result proving that the CPR education of the Emergency Medical Education Center was effective. Therefore, it is necessary to find ways for effective CPR education.
