Most TEFL courses cover the practical foundations of English teaching, including lesson planning, classroom management, grammar teaching, and teaching speaking skills. Better TEFL certifications also include tutor support, assessment tasks, and career or job guidance.

TEFL is the most common route for people who want to teach English abroad or online. TESOL is broader in wording, while CELTA is usually treated as the higher-end Cambridge option.
| Certificate | Meaning | Best For | Difficulty | Notes |
|---|---|---|---|---|
| TEFL | Teaching English as a Foreign Language | Most people teaching abroad or online | Standard | The most common label for entry-level English teaching certification and the phrase employers search for most often. |
| TESOL | Teaching English to Speakers of Other Languages | Broader teaching contexts | Standard | Often overlaps heavily with TEFL, but the label can sound broader because it includes non-native English learners in different settings. |
| CELTA | Cambridge English Level 5 Certificate | Higher-end schools and serious career paths | More intensive | A better-known premium qualification with stricter standards, usually more expensive and more demanding than a typical online TEFL course. |
Accreditation: Level 5 preferred

Reviews
Most TEFL courses take between 4 and 12 weeks depending on the format and study pace.
Shorter online courses can be completed quickly, while more substantial Level 5 courses often take longer because they include more assignments, tutor support, and structured modules.
Most online TEFL courses cost between £120 and £1500+.
Lower-cost TEFL courses tend to focus on certification only, while premium providers often charge more for Level 5 branding, tutor support, career services, or classroom and internship add-ons.
Sometimes, but it is much harder. Some informal or low-paying roles may not insist on TEFL certification, but many schools, language centres, and online teaching platforms either prefer it or treat it as a practical requirement.
If you want to teach English abroad with stronger job prospects, or teach online with more credibility, TEFL certification is usually the simplest and safest route.
Popular destinations include Asia, the Middle East, and parts of Europe, where TEFL certification helps you qualify for language school roles.
Many TEFL graduates use their certificate to teach online through platforms, language companies, or direct private lessons.
A TEFL certificate can also support freelance tutoring, niche English teaching, and location-independent teaching work.
If your goal is teaching abroad or online, comparing accredited 120-hour and Level 5 courses is usually the most practical next step.
| Type of Work | Typical Range | Notes |
|---|---|---|
| Online teaching | £8-£25/hour | Often depends on platform, experience, niche, and whether you teach privately or through a company. |
| Teaching abroad | Varies by country | Pay and benefits vary heavily depending on destination, visa rules, school type, and your experience level. |

TEFL courses usually range from around £120 for lower-cost online options to £1500 or more for premium courses with stronger support or classroom components.

Level 5 is usually the strongest keyword to look for in the online TEFL market. You should also check course hours, tutor support, reputation, and independent reviews.
In practice, there is often a lot of overlap. TEFL is the more common term for teaching English abroad, while TESOL can sound broader and may include more general English-language teaching contexts.
CELTA is often seen as the more prestigious option, but it is not automatically the best choice for everyone. If you want a lower-cost or faster route into teaching, a solid TEFL course may be more practical.
