How We Evaluate Online TEFL Courses

We consider several factors when reviewing and ranking online TEFL/TESOL providers:

Verified student reviews: Feedback from people who have taken the courses.
Course quality: The usefulness and relevance of the training for prospective English teachers.
Tutor and customer support: The level of assistance available during and after the course.
Business practices: Clear pricing, transparent course information, and the way providers handle student concerns.
Certification and recognition: The accreditation status of the program and the extent to which its certificate may be accepted by employers.

Our rankings reflect the information and reviews available to us and may change as new feedback is received.

Check Accreditation Before You Enroll

Not all TEFL/TESOL certificates carry the same level of recognition. Before paying for a course, check its accreditation, the organization behind that accreditation, and whether the qualification meets the requirements of the employers and countries where you intend to teach.

You can read our TEFL Accreditation Guide for more information about the distinctions we make between Accredited and Fully Accredited programs. These are classifications used by Trusted TEFL Reviews; accreditation terminology and requirements can vary between organizations and countries.

Read Verified TEFL/TESOL Course Reviews

Before making your decision, take time to read the individual reviews for each provider. Consider both positive and critical feedback, compare course costs and support services, and check what is included in the advertised price.

If you have completed an online TEFL/TESOL course, you can also submit your own review. Student experiences help other prospective teachers make better-informed decisions.
