what isTESOL and TEFL certifications are the most commonly recognized qualifications around the world for teaching English to non-native speakers. While the two types of certification are very similar, the technical difference is that TESOL designates teaching English to second-language speakers (ESL) in an English-speaking country, while TEFL designates teaching ESL in a non-English speaking country. Most positions you apply to, though, will treat either certification as equivalent to the other.

The major benefit of online as opposed to in-class courses is practicality. Earning your TESOL/TEFL certificate online enables you to complete the training at your leisure time, starting immediately whenever you want to begin, remotely from anywhere in the world. Understandably, online training programs are also significantly more affordable than in-classroom training. The quality of the content you are learning will not be effected in anyway.
