Introduction: The comparison of educational systems to develop new policies in higher education is increasing, which creates opportunities to learn about the educational programs of other countries and evaluate the educational system of Iran at the same time. Therefore, this study was conducted to compare the nursing master's programs (all fields) in Iran and the Vanderbilt School of Nursing in the United States (Tennessee).
Methods: The current study is descriptive-comparative research conducted using Bereday's four-stage model, including description, interpretation, proximity, and comparison. The information given from Iran's nursing master's curriculum was taken from the Ministry of Health and Nursing Schools and Vanderbilt University website and the Vanderbilt School of Nursing website
 Results: At Vanderbilt College, students are recruited internationally and independently, but in Iran, student admission is centralized and through a national exam. Paying attention to society's needs and diversity in nursing fields, the selection of diverse educational and evaluation strategies was common in Iran and Vanderbilt. In both environments, different roles and tasks of nursing have been mentioned, which are related to the field, consistent with the mission, and realistic. However, at Vanderbilt University, most of the roles are related to applying clinical reasoning and critical thinking in the clinical environment and emphasizing the use of evidence-based changes, which are not noticeable in Iran's educational curriculum.
 Conclusions: Due to the increasing progress of science and technology and continuous changes in the needs of society, the necessary changes in the curriculum of this course seem necessary so that competent and capable graduates can be delivered to society, who can provide quality and evidence-based care.
