General Category

1TEFL vs TESOL vs TEFL/TESOL - what’s the difference?

The Dux TEFL/TESOL Courses are designed to offer the best combination of academic and practical English teaching education.

For those who may not be aware - Teaching English as a Foreign Language (TEFL) and Teaching English to Speakers of Other Languages (TESOL) are often used interchangeably. However, there is a slight difference in these types of courses. TEFL courses often focus on the more academic and theoretical side of learning and teaching the English language (popular with native English speakers); while TESOL tends to focus more on the practical application of everyday life (popular with non-native English speakers). Both types of courses empower teachers to help students improve their English and can have a lot of overlap between them, which explains why so many people tend to confuse the two terms.

However, the academic developers at Dux wanted to ensure all of our students received the best of both worlds, so they intentionally developed a course that included the academic English theory of TEFL and the practical everyday application of TESOL. This is just another way that the Dux team ensure that the students who complete our TEFL/TESOL courses are properly prepared and able to teach with confidence.

2Why can’t I get access to my Dux course?
Please note that course access can only be granted once the payment for your selected course has been cleared by your bank or financial provider. Once Dux receives confirmation that your payment has been successful, we will send you an email with your log-in details for your course. You can then access your course directly from that email and begin learning your Dux course content!
3How do I get my Dux TEFL certificate?

The digital certificate and the printed certificate are available once you complete any of the accredited Dux Courses. The digital version is sufficient for teaching online and the original printed version is needed for most work visa applications.

If you need the original certificate, then we will professionally print it, emboss it with a Dux seal and have it signed by our course director. It will then be delivered to the address of your choice all for the small fee of $30 USD. Simply click the ‘order certificate’ button after you have completed the course and enter your details.

Please note that certificates are sent by post and a postal address is required. Certificates are not sent by courier to a residential address. Kindly enter your postal address when ordering.

9Can I go back and study in the same section where I left off?
Yes. Your progress is saved and you will return to the same chapter that you were on before you left.
10How do I know which TEFL/TESOL provider to use?

There is an excess of TEFL/TESOL providers online -but you must be careful of the many fake or unaccredited courses available! An unaccredited course could be the reason you do not receive a job offer or are denied a work visa. To avoid these time-wasters, make sure that the TEFL/TESOL course you choose is accredited by an official accrediting body, such as Accreditat.

This Dux TEFL certificate gives you peace of mind knowing that your Dux TEFL Courses are fully accredited by Accreditat in the UK.

11Who do I contact if I need help in my course?
A Dux tutor is available to answer questions and provide support whenever needed. You can contact a tutor before, during and after the course by sending an email to and a dedicated tutor will respond promptly.
12Are there any age restrictions?
There are no official age restrictions for this course. However, if you are wanting to teach in-person abroad as soon as possible, we do suggest that you be over the age of 18 years as this is also an immigration requirement to be able to obtain a work visa for teaching abroad.
13Certificate Authentication - what it is, why you need it, where to get it done?
Some countries (mainly China), require that any TEFL/TESOL certificate must be authenticated to apply for a work visa. A hard copy certificate with the original signature of the TEFL course director is required to have it authenticated. This is usually done by a notary public attorney. Not all countries require authentication, so be sure to check the visa requirements of the country you are applying to.
