<![CDATA[Abstract. This study is motivated by the importance of expressive language development as a foundation for early childhood communication skills and the ability to articulate ideas, feelings, and needs. Vidya Montessori Studio employs a child-centered Montessori method; thus, it is essential to examine its application in fostering expressive language development.This study aims to describe the planning, implementation, and outcomes, as well as the supporting and inhibiting factors, associated with the use of the Montessori method for expressive language development among young children at Vidya Montessori Studio. A qualitative approach with a descriptive method was employed. The research subjects were teachers at Vidya Montessori Studio. Data were collected through interviews and subsequently analyzed using data reduction, data presentation, and conclusion drawing. Data validity was verified through triangulation of sources, techniques, and time. The results indicate that lesson planning begins with observing child development to serve as the basis for creating Individual Lesson Plans (ILPs). Implementation adheres to Montessori principles, featuring teachers as facilitators, the use of Montessori materials, two-way communication, and "freedom within limits." The findings demonstrate an improvement in the children's expressive language abilities. Supporting factors include teacher competence, a conducive learning environment, the availability of Montessori materials, and parental cooperation; conversely, inhibiting factors include variations in children's characteristics, mood, and the process of adapting to Montessori-style learning. The application of the Montessori method effectively supports optimal expressive language development through child-centered learning. Abstrak.
