Before making the move to an online TEFL course, take some time and think if online TEFL training is right for you. Yes, an online TEFL certificate is going to be less intense (and probably less expensive) than an onsite course like The Language House TEFL, or any variety of onsite providers you could choose from, but will the training be the same? Even though ITA is our favorite online TEFL provider, it can’t match the experience of training onsite in a beautiful city like Prague.
