CELTA TEFL Teacher Training Course

Asia’s Biggest Cambridge CELTA Training School

When the Director of Studies at your first teaching interview asks, “Have you got a TEFL qualification?” A great answer would be, “Yes, I have the Cambridge CELTA from International House Bangkok”.


And why are International House and the Cambridge CELTA held in such high regard?

  • Every CELTA trainer is an experienced teacher, fully qualified and accredited with Cambridge ESOL
  • Every course is externally assessed by a University of Cambridge ESOL moderator
  • The course is highly practical to equip you with the skills required to teach English to adults in a variety of contexts.
  • International House schools are renowned in the TEFL world for the quality of their teacher training.
  • It was a pioneer in the field of teacher training, developing the original CELTA, also the DELTA and is the organisation that wrote and runs the distance DELTA.
  • It has the highest number of teachers and trainers who wrote the course books we use in the TEFL industry.


The 4 week course includes the observation of experienced teachers, actual teaching practice, participation in the trainer input sessions and the completion of a range of practically focused written assignments. There is no end-of-course exam but you are expected to have successfully:

  • Attended and participated in the course
  • Completed 6 hours of teaching practice
  • Observed 6 hours of lessons taught by experienced teachers
  • Submitted 4 written assignments
  • Maintained and submitted a portfolio of coursework, including lesson plans and self-evaluations.


Those trainees who have successfully completed the course will be awarded either a pass, pass B or pass A, according to the continuous assessment by our trainers.
