TEFL or TESOL - which do I need? To international employers the acronyms mean the same thing, and certificates are accepted interchangeably. What employers actually check is the number of hours, the course, and the accreditation behind your certificate. Every course below qualifies you for both "TEFL" and "TESOL" jobs.

Course questions

Online TEFL/TESOL course FAQs

Which TEFL course should I choose?

Choose the 120-hour TEFL / TESOL course to get qualified quickly; the 150-hour Advanced TEFL / TESOL for extra online-teaching training; or the 250-hour TEFL / TESOL for 250 hours of training, covering phonetics, linguistics, IELTS teaching and SEND inclusion.

Is a 120-hour TEFL certificate enough to get a job?

Yes - 120 hours is the minimum most schools, recruiters and online teaching platforms ask for worldwide. In competitive markets such as the Middle East, Japan and South Korea, a 150-hour or 250-hour qualification gives you more training to show employers.

How long do I have to complete my course?

You get 180 days' access to the 120-hour and 150-hour courses and 365 days' access to the 250-hour Professional course. All courses are self-paced, so you can finish faster or spread your study out - most students complete in 6 to 20 weeks depending on the course.

Is there a tutor, or is it all automated?

There is always a real personal tutor. On our interactive courses the short knowledge checks inside each module mark themselves instantly, so you get immediate confirmation as you study, but every assignment - the written tasks, the reflections and your lesson plans - is read and marked by a qualified tutor who writes you individual feedback. That human marking is how you develop genuine teaching skill, not just a certificate.

What certificate do I receive?

You receive a free Global English PDF certificate on completion, and can order a hard-copy ACTDEC-accredited certificate for your course. Global English has trained teachers since 1997 and has been ACTDEC-accredited since 2004.

Can I upgrade to a higher course later?

Yes. Completing the 120-hour TEFL / TESOL course lets you continue to the 150-hour Advanced TEFL / TESOL, and that course leads on to the 250-hour Level 5 TEFL / TESOL. You never lose the study you have already done. A short specialist upgrade exists only for graduates who already hold the matching Global English certificate.

Do these courses qualify me to teach English online?

Yes. Teaching English online is built into all three main courses - the 150-hour Advanced includes a full 30 hours on online teaching and setting up as a self-employed teacher, and the 250-hour Professional covers professional online teaching, including running classes on Zoom.

What payment options are there, and is there a guarantee?

You can enrol securely online and start immediately. Every course is covered by our 14-day money-back guarantee, so you can begin your training completely risk-free.
