Published: 23rd July 2025 (Updated: 31st July 2025) · 5 min read

Thinking about becoming TEFL certified but unsure whether to choose an online or offline course?

In this detailed guide, we have broken down the differences between online and classroom-based TEFL courses and the pros and cons of each option to help you decide the best path for your teaching journey.

What’s the Difference Between Online and In-Person TEFL Diploma?

Both online and classroom TEFL diplomas lead to the same result: a globally recognised TEFL qualification that qualifies you to teach English around the world.

Online TEFL courses give you the flexibility to study anytime, anywhere. They’re a great option if you’re working full-time or managing other responsibilities.
In-person TEFL courses are typically full-time, four-week, classroom-based programs held in physical locations around the world.

Whichever route you choose, make sure your course is accredited and includes teaching practice.

1. Consider Your Budget

We get it—cost matters. Whether you’re saving for flights, visa costs, or a few extra months of travel, choosing the right TEFL diploma can impact how much you can set aside.

Online TEFL courses, like our 180-Hour Level 5 TEFL Diploma, are more cost-effective. You won’t need to factor in travel, accommodation, or extra living expenses while you study.
In-person TEFL courses often require you to relocate for a month, which adds travel and accommodation to your overall costs.

2. Timelines & Scheduling: How Soon Do You Want to Teach?

If you’re looking to teach abroad in the next few months, your choice of course might depend on your timeline.

Online TEFL courses are often part-time and take around 10–12 weeks to complete, giving you the flexibility to start applying for jobs while you’re still studying.
Offline TEFL courses are intensive and can be completed in just four weeks—perfect if you’re ready to dive in and start teaching immediately afterwards.

Online study can also give you time to prepare important documents like your CV, intro video, and background check. Our TEFL jobs section is a great place to start your research.

3. Where (and How) You Want to Teach

Some countries prefer to interview and hire candidates in advance from overseas, while others mostly hire teachers who are already on the ground.

If you plan to teach in Asia or the Middle East, where schools often recruit remotely, an online TEFL course is a smart, strategic choice. You can apply and interview while completing your certification.
If you’re heading to regions like Latin America or parts of Europe, where face-to-face interviews are more common, it can be helpful to already be in-country. Some teachers take in-person courses locally as a way to acclimate and connect.

4. Learning Style & Teaching Practice

Do you love working independently or thrive in a group setting? Your learning style is key in choosing between online and classroom learning.

Online TEFL courses with The TEFL Institute are interactive and supported by expert tutors. You’ll have access to peer forums, webinars, and personal feedback throughout. Plus, you’ll complete a practical teaching component (practicum) to gain real-world classroom experience.

Offline courses offer face-to-face instruction in a classroom environment, usually with other students. You’ll work closely with a tutor and complete your teaching practicum in person, often with local ESL learners.

No matter your choice, you’ll walk away with the tools and experience needed to lead your first class with confidence.

5. Job Support & Guidance

Whether you take your TEFL diploma online or in a classroom, support matters—especially when it comes to finding your first job abroad.

All of our TEFL courses include lifetime job support, which means you’ll get help with:

Crafting a standout TEFL CV
Recording a strong self-intro video
Finding reputable job boards and recruiters
Navigating interview prep and contract review
