TEFL Certification and Accredited Courses

When applying for English teaching jobs abroad or online, an accredited TEFL (Teaching English as a Foreign Language) certification is required by most schools, language institutes and online teaching companies as they seek to hire English teachers who have been professionally trained. TEFL certification can be done online, in class or combined together in a hybrid course.

What's the difference between online, in-class and hybrid TEFL certification?

Online TEFL certification

Online TEFL courses give you flexibility to work on assignments at your own pace, studying wherever or whenever you like. These reasonably priced courses teach the same curriculum as in-class TEFL programs, but offer a more theoretical approach to teaching English as a foreign language. These types of courses are ideal for people who are working, travelling or don’t have access to an onsite TEFL program.

In-class TEFL certification

In-class TEFL courses offer would-be teachers a more hands-on approach to learning. These courses are full-time and require you to attend in-person training at a specified location and time for up to six weeks. In-class TEFL courses focus on practical teaching applications and usually include teaching practice where you can hone your skills and get feedback from an experienced instructor. Many in-class TEFL programs assist new teachers with job placement and are located in popular teaching destinations across the globe.

Hybrid TEFL certification

Hybrid TEFL courses let you study the theory of ESL teaching online and complete practice teaching sessions onsite. These types of courses are great for students who want the flexibility of studying online, but also the chance to complete in-person practice teaching and receive feedback from a qualified instructor.

So, which TEFL course is right for me?

TEFL CertificationChoosing the right type of TEFL course can seem like a minefield as there are so many companies offering a range of TEFL courses at varying prices. The main thing you need to consider is your ultimate goal. Are you looking to teach ESL online, teach English abroad, or looking to establish a long term career as an English teacher?

If you are looking for an online ESL teaching job or to teach abroad, then an accredited online 100-hour TEFL course will be enough to fulfill the requirements and land you a decent teaching job online or abroad.

If you are aiming for a career in teaching ESL or looking to teach abroad in countries like South Korea, Japan, the Middle East and China, it is recommended that you take a reputable 120-hour TEFL course with in-class training at the very least. This is highly preferred by schools and companies. Taking longer courses that include in-class training dramatically increases your chances of getting a great teaching job and shows potential employers that you have put in the effort to become a well-trained teacher.

What are TEFL course entry requirements?

There are hardly any prerequisites to enroll in an online TEFL course. You just need a fluent-level of English and the tuition fee. You don't need a bachelor’s degree or teaching credential. For in-class TEFL courses, you need a high school diploma/GED or equivalent. You will usually have an interview with a TEFL course advisor before being accepted on the course. Non-native speakers may also be asked to submit an English language proficiency test score such as an IELTS score.

Who should my TEFL certification be accredited by?

Whichever TEFL course you decide to take, you must make sure that your certification is accredited by either the Accrediting Council for Continuing Education and Training (ACCET), which is recognized by the U.S. Department of Education, Training Qualifications UK (TQUK), or the United Kingdom Accreditation Service (UKAS). These organizations are widely recognized by schools and companies throughout the world.
