What’s the difference between TEFL, TESL & CELTA?

TEFL (Teaching English as a Foreign Language) teachers teach English in non-native English speaking countries. TESL (Teaching English as a Second Language) teachers teach English in native English speaking countries. CELTA (Certificate in English Language Teaching to Adults) is a separate qualification you can get to teach English.

TEFL: One of the most accepted certificates worldwide, this allows you to teach English to non-native speakers across the globe. 

TESL: As a TESL teacher, you would likely be teaching English in your home country to students who have moved or live in an English speaking country. In other words, they are continuously surrounded by the language and will be using it every day outside of the classroom, unlike TEFL students who are likely learning in their home country.

CELTA: A very prestigious certification that follows a strict regulation created by Cambridge University. You must complete a 120-hour TEFL course and six hours of teaching real ESL students. Most of the programmes are held over a month and are full time. However, you may be able to find some courses that are part-time and are spread over three months. Due to its intense nature and requirements, the cost tends to be much higher and can be up to €1700!
