Communication skills among multidisciplinary teams and communication skills among nursing teams were shown to be the most important competencies to be improved. @*Conclusion@#The results of this study are meaningful in terms of how the core competencies of nurses were derived and evaluated for the fourth cycle of nursing education accreditation according to the changes of time and culture.
