What’s CELT-S?

Secondary school teachers can develop their classroom skills and teaching confidence with CELT-S. It’s a practical English teaching qualification that gives teachers the relevant skills to get the best from 11–18 year old learners.

The course helps teachers to create strategies for the key challenges of Teaching English as a Foreign Language (TEFL) in a secondary school context, such as classroom management with large classes and motivating learners.

Teachers build on their teaching knowledge and skills, through a combination of online study and observed teaching practice with an approved trainer.

International House Mexico is highly recognized worldwide in the teacher training area. International House was one of the pioneers in the development of practical teacher training courses. Our courses are recognized for training more efficient, more productive, more creative and more professional teachers.
