  • TEFL – (Teaching English as a Foreign Language)
    This expression is most often used when English is taught in countries where it is not the mother tongue. (for example, teaching English to Spaniards in Spain)
  • TESL – (Teaching English as a Second Language)
    TESL is the teaching of English to people whose mother tongue is another language in an English-speaking country. (for example, immigrants in the UK)

Questions about TEFL-TESOL

The abbreviation TEFL means to teach English as a foreign language. It is generally used to refer to training courses that almost everyone around the world can take to learn the skills and knowledge required to teach English to non-native speakers.

TEFL means teaching English as a foreign language and TESOL means teaching English to speakers of other languages. These images are generally used interchangeably, but TESOL is more common in the United States and TEFL is more common in the United Kingdom.

Although it is possible to teach abroad without a TEFL certificate, we recommend that you take a TEFL course before you leave. Many countries now require teachers to be TEFL certified, and many employers fire unskilled teachers because they think they do not have enough skills and knowledge.

Although it is possible to teach English online without any formal skills, it is definitely recommended that you complete a TEFL course before you begin, as many online learning platforms require applicants to obtain a TEFL certificate.

An “ESL teacher” can be used to describe different situations because teachers in this field work in different environments and teach very different groups of students. However, the common goal of every ESL teacher is to help people develop their speaking and writing skills in English.

For many years, we have provided people of all ages to start a new career as an English teacher. As long as you are open to new ideas and want to work in the classroom, your age should not be a problem.
