Top 5 Online TEFL Courses Reviewed
#1 Top Pick
The TEFL Institute
If you are looking for the gold standard in accreditation without taking out a student loan, The TEFL Institute currently holds the top spot. What sets them apart is their focus on “fast-track” methodology without cutting corners on quality.
Their 120-Hour Advanced TEFL Course is fully accredited and recognized globally. Unlike some clunky legacy platforms, their course interface is modern, mobile-friendly (they have a dedicated app), and designed for people who want to get certified and start earning quickly.
They are particularly strong for aspiring online teachers because their curriculum includes specific modules on digital classroom management—a skill set that is totally different from managing a physical classroom.
- Accreditation: Highfield (Ofqual regulated) & ACDL.
- Support: Lifetime job support and employer verification.
- Best For: Serious applicants who want a prestigious certificate fast.
#2 Best Value
Premier TEFL
Coming in a very close second is Premier TEFL. If you are nervous about standing in front of a camera for the first time, this provider is for you. They are one of the few online providers that have really nailed the “practicum” aspect of remote learning.
While many courses are 100% text-based, Premier TEFL offers excellent hybrid options. For example, their virtual teacher training allows you to practice teaching with peers on Zoom before you ever face real students. This confidence booster is worth its weight in gold.
Additionally, they offer a specific 30-Hour Advanced Course in Teaching English Online. This is perfect as an add-on if you already have a basic certificate but are struggling to understand the tech side of platforms like Zoom, DingTalk, or ClassIn.
Pros
- Includes real teaching practice options.
- Highly rated mobile app for studying on the go.
- Regular live webinar workshops.
Cons
- The specialized short courses are addictive (you’ll want to take more than one!).
#3 Trusted Name
I-TO-I
The ITOI is a solid, middle-of-the-road choice that has been around for years. They are known for their Level 5 Diploma options. If you are looking for a very academic approach to English grammar, they are a good contender.
However, their course structure can feel a bit more rigid compared to the flexibility offered by The TEFL Institute or Premier TEFL. They are a great option if you have plenty of time to study and aren’t in a rush to launch your career immediately.
#4 Budget Friendly
TEFL UK
If budget is your primary concern and you need a piece of paper to tick a box for a visa, TEFL UK offers very affordable entry-level certificates. They are legitimate and accredited, but the content is lighter than that of the top three contenders.
This is a good choice if you are volunteering or teaching casual conversation classes. Still, it might not be enough if you are aiming for top-tier international schools or high-paying corporate online gigs.
#5 Premium Price
International TEFL Academy (ITA)
ITA is often considered the “Ivy League” of TEFL certificates—with a price tag to match. Their courses are excellent, rigorous, and university-level. However, for most people wanting to teach online specifically, the cost (often $1,500+) is overkill.
You can get the same level of online employer recognition from The TEFL Institute or Premier TEFL for a fraction of the cost. Choose ITA if you plan to make a lifelong career in academia or university teaching.
Buying Guide: How to Choose Your TEFL Course
Not all certificates are created equal. When searching for the best courses for teaching English online, keep these three non-negotiables in mind:
1. Accreditation is Everything
If a course isn’t accredited by a recognized body (like Ofqual in the UK or DEAC in the US), it is essentially just a PDF receipt. Employers know the difference. Both The TEFL Institute and Premier TEFL use verifiable accreditation bodies, ensuring your certificate is accepted by major platforms like Cambly, Preply, and AmazingTalker.
2. Look for “Online” Specific Modules
Teaching in a physical classroom is different from keeping a 6-year-old engaged through a webcam. The best courses will have dedicated modules on:
- TPR (Total Physical Response) for video: How to use your hands and body within the frame.
- Digital Props: Using software like ManyCam.
- Platform tech: Troubleshooting audio/video issues.
3. Hours Matter
Do not buy a “40-hour” or “weekend” course. The international industry standard is 120 hours. Anything less will automatically disqualify you from the higher-paying jobs. If you want to future-proof your resume, consider a Level 5 Diploma (usually 168+ hours), which is equivalent to an associate degree in teaching difficulty.
Frequently Asked Questions
Can I teach English online without a degree?
Yes! While some specific countries (like China or South Korea) require degrees for visa purposes, the “online” world is much more flexible. Many platforms and private tutoring marketplaces only require a 120-hour accredited TEFL certificate. Premier TEFL has a great guide on teaching without a degree that delves deeper into the topic.
How much can I earn teaching online?
Rates vary wildly. Non-native speakers or those with cheap certificates might earn $10/hour. However, with a high-quality certificate from a top provider like The TEFL Institute, native speakers can command $20–$30+ per hour, especially if they specialize in Business English or Exam Preparation (IELTS/TOEFL).
Is the market saturated in 2025?
The “easy money” days of 2018 are gone, but the market isn’t saturated—it’s specialized. There is a shortage of qualified teachers in specific niches (such as teaching adults, business English, or science in English). A generic teacher struggles; a specialized teacher with a top-tier certification thrives.
Choosing the right course is the first investment in your new online teaching business. Don’t cheap out on the foundation.
For the best balance of prestige, speed, and modern curriculum, The TEFL Institute is our #1 pick for 2025. If you need a bit more hand-holding with practicum and specialized online training, Premier TEFL is the perfect alternative.
