In essence, there shouldn’t be any difference between online and on-site courses. Thanks to current technologies, it is possible to deliver top TESOL/TEFL training online without lowering the quality of the course. TESL Canada has been accepting online TESOL programs (many of which are offered by the most reputable Canadian universities) for almost a decade, CELTA is about to launch its own online TEFL course, and both Cambridge and Trinity College of London have been offering a large online component for their diploma courses, DELTA and Trinity DipTESOL respectively.
The main problem with most online TESOL courses is not the delivery mode, but the content of the course and the level of the assignments. Few online schools have experience delivering advanced programs such as TESL Canada, Trinity CertTESOL, or CELTA. Their courses are quick and easy and they offer poor training in lesson planning, which is the most essential component of a TESOL or TEFL course.
Coventry House International is the first Trinity CertTESOL center in North America and offers quality online TESOL courses. You can choose from the 100-hour TESOL certificate program or the advanced 250-hour TESOL Diploma, which is recognized by TESL Canada Professional Standard 2 after a 20-hour Practicum is completed and is more advanced than any 5-week on-site TESOL course.
