Tree House

The Tree House program is for students with an English or bilingual preschool background. Foreign teachers further develop students’ natural English speaking skills from 1st through 6th grades in a total immersion environment. The program is theme-based with different units or themes per semester. Each unit includes a theme-related storybook, song, dialogue, writing and phonic exercises, grammar component, poem, and integrated activities.

Step Ahead

Step Ahead is a standalone course that takes children in 3rd grade with no prior English knowledge and by 6th grade, transforms them into confident, near-fluent English communicators. Our program has a strategic balance of listening, speaking, reading, and writing. Regular lessons are broken into phonics, reading, grammar patterns, conversation, songs, and homework preview
