Some have worked as inspectors, advisers or administrators in Ministries of Education or other public offices. Others have worked for private schools or companies as language trainers or managers. Some have gained experience as materials writers and course designers. They may be expecting to take on new responsibilities or they may want to gain more advanced qualifications and develop or update their expertise. A number come straight from university after completing a first degree in English, language study or education and have made a decision, perhaps with some experience of tutoring or teaching, that they will pursue a career in the teaching of English language, either in the public or private sector.
Some people embark on a career in English language after working in another capacity for a while.
The diversity of the student population also means that you can discuss your experience and your new learning with classfellows and colleagues from many parts of the world and many sectors of the ELT profession.
