This study was to develop the simulation learning scenario using standardized patients, and to evaluate the effect of it. This study was a pre-post test design with a single group and participants were recruited from fourth-year nursing students at a university. This study has developed the case scenario for a patient with spontaneous intracerebral hemorrhage and the simulation learning using standardized patients, which was applied in this study, had improved problem solving ability and clinical performance ability on nursing students. Through this study, the nursing student will grow up to be a professional nurse by learning the nursing assessment including consciousness assessment. Also, the simulation learning scenario using standardized patient should be developed in the various fields.
