ABSTRACT
Difficulties encountered in nursing clinical education, limited clinical practice time, and the COVID-19 outbreak negatively affect the clinical practice and duration of students with real patients. For this reason, it is aimed to develop nursing students' competencies such as critical thinking skills, learning and self-confidence through various teaching approaches. Educational strategies such as simulation-based education offer students the opportunity to clinical practice in a safe environment by providing realistic clinical situations. The concept of fidelity plays an important role in the selection of the simulation method. Selection of simulation method and fidelity level, depend on factors such as the goals and results of the education, student level and facilitator. In the literature, there are different classifications related to simulation methods and the concept of fidelity. Although the classifications made are similar to each other, there are also differences between them. In this review, different classifications and definitions of fidelity regarding simulation-based education features found in the literature are examined. © 2022, Dokuz Eylul University.
