The classes in Tsinglan Preschool are made up of PreK class (2.5-5-year-old mixed-age) and K class (5-6-year-old).

Based on the Montessori Education Philosophy, the PreK class combines thematic teaching with the Montessori method. To develop children's cognition, concentration, coordination, independence, creativity, and sociality, contents such as virtues education, sports, and library reading course have been added to the five areas of the Montessori Curriculum i.e., the practical life area, the sensorial area, the math area, the language area, and the cultural studies area. Meanwhile, the English immersive environment we created allows children to pick up the language naturally in their daily lives.

Class K also adopts the theme-based learning model whereby the teachers focus on children's comprehensive development and bilingual proficiency at the same time. This model promotes the integration of Chinese and Western languages and cultures and prepares the children for a smooth transition to Grade one.
