For most beginners, a 120-hour TEFL certificate is the recommended starting level, as it is the widely accepted entry standard. Those wanting more depth, specialisation or stronger prospects can choose longer diploma or advanced pathways. For most newcomers the 120-hour certificate is the pragmatic starting point, with room to build from there. The 120-hour certificate is the pragmatic start, with room to build from there.
The 120-hour standard
The 120-hour TEFL certificate is the most widely recognised entry-level qualification and is accepted by many employers and platforms.
For most newcomers, it is the sensible starting point.
When to go further
Longer courses — 150, 250 or 350 hours — add depth, specialisation and can strengthen competitiveness, especially for better-paid roles.
They suit those serious about a TEFL career.
Specialisation options
Higher levels and add-ons cover areas like teaching young learners or business English, widening the roles open to you.
Specialisation can set you apart.
Choosing your level
Base your choice on your goals, budget and how committed you are to teaching English long term.
You can also start at 120 hours and build up later.
When beginners should consider more than 120 hours
Some beginners are better served starting higher. If you are committed to TEFL as a career, aiming at competitive markets, or want to specialise early in areas like young learners or business English, a longer or combined pathway can pay off.
If you are testing the water or want to start earning sooner, the 120-hour certificate lets you begin and add further study later. Matching the level to your commitment avoids both under- and over-investing at the start.
Choosing a quality course, not just a level
Beyond the number of hours, the quality of a course matters: look for solid content, tutor support and good employer recognition rather than hours alone.
A well-structured 120-hour course can serve you better than a longer but thinner one, so compare what is actually taught.
Checking how your target employers or platforms view a course helps ensure your investment opens the doors you want.
What to check
- Whether 120 hours meets your goal
- Interest in deeper or specialist study
- Budget and time available
- Target roles and their expectations
- Option to build up later
- Your level of commitment to TEFL
- Whether to specialise early
Important distinction
Course hours indicate depth, not a guarantee of recognition. Check what your target employers, platforms or countries actually require.
