The Montessori educational philosophy, founded by Maria Montessori, emphasizes the holistic development of preschool children, focusing on their innate abilities and fostering independence and self-regulation. In Vietnam, the application of Montessori principles in preschool education has gained traction, albeit with several challenges. This paper assesses the implementation of Montessori education in Vietnamese preschools, examining successful cases and existing hurdles. Drawing from a range of sources, including scholarly articles, books, and dissertations, the analysis highlights the shortage of adequately trained Montessori teachers, high tuition fees, and misconceptions about the Montessori approach. The study proposes solutions such as enhancing teacher training, international collaboration, and improving infrastructure and financial support for Montessori preschools. Furthermore, the paper underscores the significance of applying Montessori principles in Vietnamese early childhood education and suggests future directions for development. By adhering to Montessori's core principles and addressing the identified challenges, this approach has the potential to optimize preschool children's capacities and contribute to the nation's future development.
