Why are TEFL course hours important?
For many aspiring English teachers, the choice eventually comes down to a 120-hour or 150-hour TEFL course. Both can provide substantial training, but they are designed for slightly different levels of depth.
What does a 120-hour course offer?
The 120-hour level is commonly used as an industry benchmark. It provides enough time to cover core methodology, lesson planning, classroom management, language systems and the four language skills in meaningful detail. For many first-time teachers, it offers a practical balance between training depth and study commitment.
What does a 150-hour course add?
A 150-hour course goes further. The additional hours can allow more detailed treatment of methodology, planning and specialist or advanced topics. This can be valuable if you are new to teaching, want a stronger theoretical foundation or intend to pursue TEFL as a longer-term career rather than a short experience abroad.
Which course is better for beginners?
More hours do not automatically make someone a better teacher. Course quality, assessment, support and how seriously you engage with the material are equally important. A strong 120-hour course is more useful than a poorly designed programme with a larger number printed on the certificate.
How should you decide?
At TEFLEN, the Advanced 120-Hour course is designed as a comprehensive route for aspiring teachers, while the Master 150-Hour course provides a broader programme for learners seeking additional depth.
If an employer specifies a minimum of 120 hours, both a 120-hour and 150-hour qualification may satisfy the hours component, subject to the employer’s other requirements. However, never assume that course hours alone determine eligibility. Degree, visa, nationality, experience and language requirements can also apply.
Choose the 120-hour route if you want comprehensive core preparation and a widely used qualification level. Consider 150 hours if you value additional training, want to strengthen your professional profile or simply prefer to enter teaching with more preparation.
The most useful question is not “Which certificate is bigger?” but “Which course will prepare me best for the type of teaching I want to do?”
