Is a 120-hour TEFL course enough?

Why 120 hours became the standard

Over time, language schools, recruiters and visa processes settled on 120 hours as the point where a course covers methodology, grammar, phonology, lesson planning and classroom management in enough depth. Many job adverts simply say '120-hour TEFL required'.

When 120 hours is enough

• Teaching English online with most platforms and marketplaces
• Entry-level jobs in language centres in Vietnam, Thailand, Cambodia, Turkey and Latin America
• Meeting the TEFL part of the visa requirement in countries such as China (where it can replace two years' experience)
• Private tutoring and spoken-English classes

When to choose more

• You want to teach children: add the 60-hour Young Learners course
• You want corporate clients: add Business English Teacher Training
• You want better pay, senior or training roles: choose the 150-hour Diploma or higher
• Your employer wants observed practice: arrange teaching practice (London College of Teachers provides a recommendation letter)

What employers check besides hours

Your degree (for most visas), your English level, any teaching experience, whether the certificate can be verified, and how you perform in a demo lesson. A 120-hour TEFL gets you through the door; your teaching gets you the job.

What a 120-hour course should contain

Hours alone do not make a course good. A credible 120-hour TEFL should cover teaching methodology, how languages are learned, grammar for teachers, pronunciation, vocabulary, lesson planning, classroom management and the four skills, and it should assess you through quizzes and written work such as lesson plans.

London College of Teachers' 120-hour Certificate covers nine core modules: the world of teaching English, the history of methodologies, language acquisition, English grammar, phonology, vocabulary, lesson planning, drama and games, and the four skills.

120 hours compared with longer courses

• 120 hours: the standard entry level; enough for most first jobs and online teaching.
• 150 hours: adds advanced grammar and phonetics; useful if you want to stand out.
• 250 hours: adds a specialism (young learners or business English), a research project and management basics.
• 350–480 hours: postgraduate-level depth with research and management, for graduates aiming at senior roles.

Is a 120-hour TEFL enough for specific countries?

• China: yes for the TEFL part of the visa route (with a degree and native-speaker nationality usually required).
• South Korea and Japan: yes as the TEFL; visas depend on degree and, for Korea's E-2, nationality.
• Vietnam and Thailand: yes, alongside a degree for the work permit.
• UAE and Saudi Arabia: yes as the TEFL; employers also want a degree and experience, and some ask for CELTA.
• Latin America and Cambodia: usually yes, sometimes without a degree.
• UK accredited language schools: often no; many ask for CELTA or Trinity CertTESOL.

What about online teaching?

For online platforms, 120 hours is almost always enough. Some companies ask for a degree as well, while marketplaces where you set your own rate usually only want a TEFL and strong English. A specialism in young learners or business English helps you get regular students.

How to make a 120-hour TEFL go further

• Add 6 to 20 hours of real teaching practice and keep a short log and references.
• Add a specialism: Young Learners (60 hours) or Business English (120 hours).
• Record a 5-minute demo lesson for applications.
• Prepare evidence of your English level if you are a non-native speaker.
• Upgrade later to a Diploma or PG Diploma as your career grows.

Cost and time

London College of Teachers' 120-hour TEFL Certificate costs US$185, £160 or ₹14,750 including GST, and it is designed for up to four months of self-paced study. Many learners finish faster by studying 8 to 10 hours a week.

Signs a 120-hour course is not good enough

• It promises a certificate in a few days.
• It has no assessment beyond clicking through slides.
• There is no tutor support or way to ask questions.
• The certificate cannot be verified by employers.
• The provider is not a registered organisation you can check.

Frequently compared: 120 hours vs 150 hours at LCT

At London College of Teachers the 120-hour Certificate (US$185) covers the nine core modules. The 150-hour Diploma (US$275) adds Advanced Grammar and Advanced Phonetics and access to a senior mentor with more than 35 years of ESL experience. If you plan to teach higher-level adults, prepare IELTS candidates or you are a non-native speaker improving pronunciation, the Diploma's extra units are worth the difference.

The bottom line

For most people, a well-taught 120-hour TEFL plus some real teaching practice is enough to start. Choose longer courses for depth, specialisms and career progression, not because 120 hours is too few.
