Although most course participants are native speakers of English there are sometimes non-native speakers who are fluent in English. A typical course will have several people in their early twenties, some who are recent graduates and want to travel overseas in order to get work experience. Other older trainees may want a career change or be approaching, at, or past retirement age and may want to start another career or earn money while they travel the world. Most trainees have come especially to do the course in their chosen location, while a few are already based there. In addition, although the Cert.TESOL is an initial training course, i.e. for those who have no previous experience of teaching English, there may be trainees on the course who have taught English before and who wish to gain an ELT qualification. However, seminar input and guidance for teaching practice will assume no prior teaching experience.
