The Trinity CertTESOL (Certificate in Teaching English to Speakers of Other Languages) is one of the two globally benchmark qualifications for English language teachers — alongside the Cambridge CELTA — and is widely regarded as the entry-level qualification of choice for those who want a career in serious, professional English language teaching. At Level 5 on the Regulated Qualifications Framework (RQF), it sits at the same level as a foundation degree or the first year of an honours degree, reflecting the depth of knowledge and classroom competence it develops.
The qualification is awarded by Trinity College London, one of the UK's most respected awarding organisations with over 160 years of history in arts, music, and English language assessment. Trinity's CertTESOL is accepted by language schools, English teaching institutes, universities, and international education providers in over 100 countries. It is regulated by Ofqual in England and accredited by Quality and Qualifications Ireland (QQI), giving it the regulatory standing that many employers — particularly in the Middle East, Asia, and Latin America — specifically require.
The part-time programme at Learnfast is structured across two progressive phases. The first phase introduces the essential foundations of English language teaching through a 120-hour Level 3 preparatory course covering lesson planning, classroom methodology, language awareness, and the principles of effective instruction. This phase ensures all learners — regardless of prior teaching experience — arrive at the Level 5 component with a robust shared understanding of TEFL fundamentals.
The second phase is the full Level 5 Trinity CertTESOL itself. This covers language-teaching methodologies in depth, exploring communicative language teaching, task-based learning, the lexical approach, and contemporary blended and online methods. Learners study language awareness across English grammar, vocabulary, and phonology, learning how to explain and teach linguistic concepts accurately and accessibly to non-native speakers. Unit input sessions cover lesson planning and design, material development, teaching across specialisms including Young Learners, Business English, and Academic English, and reflective professional practice.
The teaching practice component is a defining feature of the CertTESOL and distinguishes it from purely online TEFL certificates. Candidates complete supervised teaching practice sessions with real English language learners, receiving observer feedback and completing post-lesson reflective tasks. This component ensures that CertTESOL holders have demonstrated actual teaching competence, not just theoretical knowledge — which is why it commands such respect from employers worldwide.
Assessment is by a combination of written assignments, language awareness tasks, a teaching practice portfolio, and observer assessments during teaching practice sessions. On successful completion, candidates receive the internationally recognised Trinity CertTESOL certificate directly from Trinity College London.
