The core training programme for new teachers is the IH Certificate in Teaching Languages (IHCTL). The format and content is very similar to the CELTA and Trinity TESOL; the difference is that the course is assessed and accredited by IHWO’s Assessment Unit but not by an external exam board. The IHCTL is an intensive 120-hour 4-week comprehensive and practical teacher training course which provides candidates with the methodology and hands-on teaching practice required to effectively manage an ESL classroom. Trainees get the necessary competencies to become successful language instructors and a solid foundation to continue learning and developing as a teacher.
