The Trinity Certificate in TESOL course is one of the most widely recognized and highly regarded TEFL qualifications. Any potential employer, if they have any knowledge at all of English as a foreign language, will know the Trinity Certificate in TESOL course. In addition, the courses are validated, and syllabus and assessment criteria are fixed by Trinity College London. This assures quality control in a number of areas. All centres are subject to approval by Trinity College London, and have to maintain standards in order to retain this approval. If a centre is failing to meet the required standards, approval to run courses will be withdrawn by Trinity College London. Every Trinity Certificate in TESOL course is moderated by an external assessor. Each Trinity Certificate TESOL course trainer has to be approved by Trinity College London (which includes meeting their requirements regarding teaching experience and qualifications) and has to undergo a lengthy induction process. All the above contribute to the excellent reputation that the Trinity Certificate in TESOL course enjoys.
