Simulation is an integral component of undergraduate nursing education because it allows for a safe, timely, and prescriptive approach to meet learning objectives at the levels of individual simulations, courses, and academic programs. This review of the literature provides an overview of steps taken to move simulation forward in undergraduate nursing education, and it highlights educational theories, research, best practices, and policy statements underpinning modern nursing simulation. This chapter outlines simulation and curriculum integration approaches and provides examples of participant, course, and program outcomes.
