Why Duke

A better way to learn English

Small classes, native teachers, and a proven method that’s worked for thousands of students across Bangkok.

Native, Certified Teachers

All English teachers are native speakers with CELTA, TESOL, or DELTA certification — and years of teaching experience here in Bangkok.

Small Class Sizes

Maximum 8 students per class, so every learner gets real speaking time and personal attention from the teacher.

Speak From Day One

Our method puts speaking front and centre — you’ll be using English actively from your first lesson, not just memorising grammar.

Clear Learning Path

Six structured levels from beginner to advanced, with placement tests, progress checks, and end-of-course certificates.

Monthly Intakes

New courses start every month — you never have to wait long to begin, and you can join the level that fits you.

Central Location

Right on Sukhumvit Soi 13, 5 minutes’ walk from Nana BTS — easy access whether you live in town or commute in.

Course Format

Built for real progress

Every Duke English course follows a proven 4-week intensive format with structured progression, regular assessments, and a clear path from your starting level to fluency.

Monthly intensive cycles Each level runs as a focused 4-week course — long enough to make real progress, short enough to fit your schedule.
6 levels, A1 to C1 From absolute beginner (A1) through to advanced (C1) — with placement tests so you join exactly the right level.
Active speaking practice Pair work, group discussions, role-plays, and presentations — you’ll speak English in every single class.
Progress assessments Weekly mini-tests and an end-of-course assessment, with a certificate when you complete each level.
