S1 is Harmony’s English-medium middle school program designed for students who are ready to learn core subjects through English while continuing to build strong academic language skills.

We keep class sizes small so teachers can give frequent feedback, adjust pacing, and coach each student’s next steps. Our program combines clear structure with student independence: explicit teaching, guided practice, discussion, and project-based learning.

Alongside academics, we teach skills-based learning that transfers beyond school—communication, collaboration, research, problem-solving, and presentation—so students can use what they learn in real situations.
