Certificate in Teaching English to Speakers of Other Languages (TESOL)

TESOL certificates teach the craft of language teaching — lesson planning, classroom technique, how grammar is actually acquired versus how it is explained — with observed teaching practice at the core of any credible programme. University-issued certificates carry more weight than the unregulated short courses the field is cluttered with, which is exactly why the provider matters more here than in most certificate study.

The qualification's appeal is portability: English teaching demand exists on every continent, and the certificate is a fast, legitimate credential for graduates funding travel, career changers testing education, and teachers adding a specialism.

A short, practical teaching qualification with genuinely open entry — its purpose is to make you employable quickly.

• Completed secondary education at minimum; many providers ask for a bachelor's degree because employers abroad usually do.
• Strong English — native-level or a high proficiency score. Non-native speakers are accepted and widely employed.
• No teaching experience required; the course assumes none.
• An interview or written task at the more reputable providers, which is a good sign rather than an obstacle.
• Minimum age of eighteen or twenty, depending on the provider.

Course quality varies enormously and so does employer recognition. Prioritise a provider with externally moderated assessment and, crucially, observed teaching practice with real learners.

A qualification that opens teaching work internationally, quickly, at entry level.

• English language teaching abroad — private language schools across Asia, Europe, Latin America and the Middle East.
• Online English teaching, now a large and flexible market.
• Examination preparation — IELTS, TOEFL and Cambridge courses, generally better paid than general English.
• Business English and corporate training.
• Young learners, a large share of the global market and often requiring a further specialist module.
• Progression to a diploma-level qualification and then to senior teaching or academic management.

Pay and conditions vary widely by country and by school, and visa requirements differ — many countries require a bachelor's degree for a work permit regardless of the certificate. Research the specific destination before committing.

Typically four to twelve weeks, intensive and overwhelmingly practical — the observed teaching is the qualification.

• Language awareness — the grammar, phonology and lexis of English described well enough to teach it.
• Teaching methodology — lesson planning, staging, and communicative approaches.
• The four skills — teaching reading, writing, listening and speaking.
• Classroom management and adapting to mixed-ability groups.
• Assessment and feedback, including error correction.
• Observed teaching practice with real learners, plus observation of experienced teachers. This is the part that matters.

A course without assessed teaching practice on real students is worth very little to an employer, whatever it is called. It is the first thing to check and the first thing a good school asks about.
