In order to get the most out of your course and to become a more rounded teacher it is advisable to back up your face-to-face weekend course with an online TEFL course.
If you add on online components up to the tune of 120 hours, you will find that not only is your TEFL course better respected around the world, but that you are eligible for job placement in one of several countries worldwide through the 120 hour course provider. See the 120 hour course pages for more information.
