Simulation-Based Learning (SBL) has emerged as a transformative educational strategy in healthcare education, enabling students and professionals to acquire, practice, and refine clinical skills within a safe and controlled environment. Traditional apprenticeship-based training models often expose learners to variability in patient cases and limited opportunities for repetitive practice. Simulation technologies, including high-fidelity manikins, virtual reality systems, standardized patients, and computer-based simulations, address these limitations by providing realistic clinical scenarios without compromising patient safety. This review explores the role of simulation-based learning in clinical skills development, examining its educational foundations, applications, benefits, challenges, and future directions. Evidence suggests that simulation significantly improves clinical competence, decision-making abilities, teamwork, communication skills, and patient outcomes. Furthermore, advances in artificial intelligence, immersive technologies, and digital healthcare systems are expanding the capabilities of simulation-based education. The study concludes that simulation-based learning should be integrated into healthcare curricula as a core component of competency-based education to prepare healthcare professionals for increasingly complex clinical environments.
