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 (120 is the standard minimum), the level, and the accreditation behind your certificate. Every course below qualifies you for both "TEFL" and "TESOL" jobs. Read the full TEFL vs TESOL guide →

Course questions

Online TEFL/TESOL course FAQs

Which TEFL course level should I choose?

Choose Level 3 (120 hours) to get qualified quickly to the industry standard; Level 4 (150 hours) to stand out to employers with extra online-teaching training; or Level 5 (250 hours) for the strongest CV, covering phonetics, linguistics, IELTS teaching and SEND inclusion. You can start at Level 3 and upgrade later.

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 Level 4 or Level 5 qualification can help your application stand out.

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?

Every Global English course includes a real personal tutor who marks your assignments and gives individual feedback throughout. Nothing is auto-marked - tutor feedback 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 prestigious hard-copy ACTDEC certificate at Level 3, 4 or 5 depending on your course. Global English has been ACTDEC-accredited and training teachers since 1997.

Can I upgrade to a higher course later?

Yes. If you complete the 120-hour Premier course, our 30-hour upgrade course takes you to the Level 4 Advanced qualification, and the Advanced course leads on to the Level 5 Professional. You never lose the study you've already done.

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 building independent income, 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.
