TESOL/TEFL Certification Guide for Teaching English Abroad

The TEFL/TESOL certification market includes everything from rigorous accredited programs to weekend courses of questionable value, and because the field is largely unregulated, the burden is on you to tell the difference before enrolling.

The 120-hour benchmark

Most reputable employers — language schools, government teaching programs — specifically look for a certificate of at least 120 hours, and increasingly ask whether it included a practicum (actual supervised teaching practice, not just coursework). Anything significantly shorter is unlikely to satisfy hiring requirements at established schools, regardless of what the course itself claims.

Accreditation matters more than the provider's name recognition

Look for external accreditation from a recognized body rather than trusting a provider's own marketing claims about quality. Some countries' visa or work-permit programs specifically require accredited certification, and finding this out after enrolling in an unaccredited course is a common, costly mistake.

In-person practicum vs fully online

A fully online, no-practicum certificate is faster and cheaper, but many employers — especially in more competitive placement countries — prefer or require a program that included real supervised teaching practice. If you have a specific target country in mind, check its typical requirements before choosing a course format.

What actually helps you get hired beyond the certificate

Any prior tutoring, volunteering, or teaching experience — even informal — meaningfully strengthens an application beyond the certificate alone. Schools hiring TEFL teachers are ultimately hiring for classroom management and communication ability, which a certificate signals but doesn't guarantee.
