The 11 Best Online TEFL Courses

You already know earning an online TEFL certificate is a great way to boost your teaching credentials, but how do you know which program is best for you? Check out these 11 top rated programs for inspiration!

Teaching English opens doors to a rewarding career that can take you all over the world. English is in demand and you'll find enthusiastic students of all ages just waiting to learn. Although some countries allow native speakers to teach without a degree or certificate, a TEFL (Teaching English as a Foreign Language) course could enhance your job prospects and earning potential. Most importantly though, it can give you the tools to be a more effective teacher for your students.

You may be wondering if it's better to get a TEFL course in person or online. Online TEFL courses provide the flexibility to study where and when is convenient for you. I teach English in Spain for a program that only requires a bachelor's degree in any subject. However, to give me more confidence, I decided to do an online TEFL course. I found the course really helpful for remembering grammar structures as well as generating new ideas for activities and games to use in the classroom. It was a small investment that I believe markedly enhanced my teaching skills.

In 2020, consider pursuing an online TEFL course. We have handpicked the best of the best for you and highlight their features below. Starting one of these courses could be the first step toward the adventure of a lifetime!
