There are lots of companies around the world offering TEFL courses but with so much choice it can be hard to know which course to take and which company to book with.

To help, we have put together a guide to top rated reputable international companies offering accredited TEFL certification courses.


How to Choose the Right TEFL Course/Company

It can be difficult to know which TEFL course to take and it is very important you research all before booking. Firstly, you need to decide whether you want to study online, or take a classroom course. Some companies offer online courses, others classroom, and some worldwide companies offer both. 

Some companies all offer paid internships or a guaranteed job on completion of a course. Most reputable companies offer lifetime assistance/support which can be of great benefit when embarking on a new adventure teaching overseas.

The TEFL companies we have listed below have been in the industry for years and offer reputable accredited courses. These companies are highly recommended if you are thinking about getting TEFL qualified and teaching English overseas for the first time.
