All 58 international Online TEFL/TESOL certification course programs currently listed on Trusted TEFL Reviews are ranked based on verified customer reviews.
Customers rate programs using the star-rating system:
5-star review: ‘Excellent’.
4-star review: ‘Very Good’.
3-star review: ‘Good’.
2-star review: ‘Very Bad’.
1-star review: ‘Terrible’.
Online TEFL/TESOL courses can be either ‘Unaccredited’, ‘Accredited’, or ‘Fully Accredited’.
‘Fully Accredited’ is the highest form of accreditation. A TEFL/TESOL certificate from a fully accredited program equates to the worldwide recognition of the certification and access to the best-paid teaching jobs.
A TEFL/TESOL certificate from an ‘Accredited’ program won’t necessarily be internationally recognized and will place you at a significant disadvantage when applying for teaching English jobs when you are up against applicants with fully accredited certificates.
‘Unaccredited’ TEFL/TESOL certificates are sometimes accepted by employers, but your employment options are dramatically reduced and the schools that will employ you tend to have poor reputations.
