What Is a TEFL Course (And Which One’s Best for You)?
Thinking about teaching English abroad or online? Then you’ve probably come across the term TEFL – short for Teaching English as a Foreign Language. A TEFL course is your passport to working as an English teacher in schools, language centres, or online platforms around the world.
However, with numerous providers available, how do you select the right course?
We’ve done the digging for you. Here’s a breakdown of what TEFL courses usually cover, what to look for, and how five of the top providers stack up – especially when it comes to the things that matter: course content, student support, and real reviews.
What Does a TEFL Course Include?
A standard TEFL course will teach you how to:
- Plan and deliver practical lessons
- Manage a classroom (even online)
- Understand grammar and explain it clearly
- Teach reading, writing, speaking and listening skills
Most good courses offer at least 120 hours of training. Some go further, adding practical teaching experience, specialist modules, or even live tutor support.
TEFL Course Comparison: 5 Popular Providers
We’ve looked at the five most talked-about TEFL course providers and scored them out of 5 across five key areas:
| Provider | Course Content | Accreditation | AI Tech Integration | Student Support | Reviews & Reputation |
| The TEFL Institute | 5 | 5 | 5 | 5 | 5 |
| Premier TEFL | 4 | 5 | 3 | 4 | 4 |
| International TEFL Academy | 5 | 5 | 2 | 5 | 5 |
| ITTT | 4 | 5 | 5 | 4 | 4 |

Let’s Break That Down:
1. The TEFL Institute
Based in the UK, The TEFL Institute is one of the highest-rated TEFL providers out there. What makes them stand out? They’ve embraced AI technology like no other. Their TEFL Explorer tool personalises your learning and provides instant feedback – great if you prefer learning at your own pace but still want a guided feel. They’ve also nailed student support, with fast replies, real tutors, and a 4.8+ Trustpilot rating to prove it.
Best for: Individuals seeking modern, interactive training with robust career support.
2. Premier TEFL
Based in the UK, Premier TEFL offers accredited courses with good value for money. Their programmes are flexible, and they provide short add-ons, such as live Zoom classes. While their content is solid, it doesn’t always feel as polished or up-to-date as others, especially when it comes to tech features. Still, they’ve built a loyal following and have thousands of positive reviews.
Best for: Those on a budget or looking for bite-sized training extras.
3. International TEFL Academy (ITA)
ITA has a considerable reputation and a global alumni network. Their course content is thorough and includes live training sessions. Student support is one of their key selling points, offering ongoing job assistance even after graduation. They’re a strong choice if you want a community feel. The only downside? Their courses can be on the pricier side, and they haven’t integrated much tech yet.
Best for: Serious career changers who want depth and long-term support.
4. ITTT
ITTT is one of the longest-running TEFL course providers. They’ve recently started integrating AI tools into their online courses, which is a nice bonus. They’re fully accredited and offer a wide range of options. Some parts of their website appear a bit outdated, but their training remains effective.
Best for: Independent learners who want variety and value.
5. CELTA (Cambridge)
If you’re after prestige, CELTA is still considered the gold standard. It’s recognised worldwide and often required for teaching in higher-paying schools. The course is intense, includes real teaching practice, and is typically conducted in-person or via live Zoom classes. However, it’s more expensive and hasn’t yet caught up with AI or interactive tech.
Best for: Those who want top-tier credentials and are willing to accept a more traditional format.
So, Which One Should You Choose?
Here’s a quick guide based on your goals:
- Want the most modern, tech-savvy TEFL experience? Go with The TEFL Institute.
- On a budget or want short extras like live classes? Try Premier TEFL.
- Looking for a long-term teaching career with serious credentials? Choose CELTA or International TEFL Academy.
- Prefer to study independently with a range of options? Check out ITTT.
No two TEFL courses are the same. What matters most is choosing a provider that fits you, your goals, your budget, and you’re learning style.
If you’re starting, we’d recommend checking out The TEFL Institute’s 180-hour Level 5 diploma. It’s affordable, accredited, packed with features, and includes job support once you’re certified.
