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, obtaining your TEFL (Teaching English as a Foreign Language) certification 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 enroll in 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 earn my TEFL certificate. 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 2024, 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!
Key factors to consider when picking an online TEFL program
Before we dive in, let's go over criteria to consider when picking a TEFL program. You'll want to research and identify these key factors before you invest your time and money in a TEFL course!
- Accreditation: Opting for an accredited TEFL course will help verify that your class will meet industry standards, cover the required hours of training, and provide you with the necessary amount of instruction and teaching practice.
- Length of course: In order to ensure your chances of getting a teaching job after your course ends, your online TEFL certification course must cover at least 100 hours of class time and 20 hours of teaching practice.
- Cost: While it's important to pick an affordable TEFL course, you should also be wary of any super cheap classes. Online classes tend to already be less expensive, but be sure it includes practical teaching experience, otherwise you're potentially wasting money!
- Job placement assistance: You're taking this TEFL course to get a job after, right? So if you're going to invest your time, make sure this course can also provide you with important resources such as interview assistance, referrals, and job guidance.

What are the benefits of an online TEFL certification?

Additionally, online programs also tend to be lower in cost (read: better for your wallet). The instruction itself online is more heavily focused on theory than classroom practice. This can be very beneficial for those who have limited teaching experience as understanding the theory and methodology behind teaching practices is fundamental in helping new teachers succeed in the classroom.
Where can I teach with an online TEFL certification?
The regions where online TEFL certification it is most widely accepted or required are Latin America and Asia. However, no matter where in the world you are planning to teach, having a TEFL certification will be an asset. Not only will it help you stand out from other applicants, it will also better prepare you to be a more effective classroom teacher which will have a positive impact on your students -- no matter if they are in South Korea, Nepal, Brazil, Hungary or beyond.
How many hours should my online TEFL certification be?
The length of online TEFL certifications vary widely. The bare minimum is usually 20 hours, but some are up to 240 hours. Choosing which course level is right for you largely depends on your long-term teaching goals, as different teaching jobs require different levels of TEFL qualifications. For most new teachers a 100-hour course will open up the most job opportunities, as well as give you the confidence to teach effectively. You can always take more classes later should you choose to pursue TEFL as a serious career. Shorter courses are good for teachers who may only be exploring TEFL as a short-term career break.
