The Teaching of English:

The most generic term for the field of teaching English is ELT. This simply means:

English Language Teaching.

ELT is a large area, and there are many subdivisions and specialisms. One subdivision is the teaching of English to learners whose first language is not English. The three terms most commonly seen here are TESOL, TEFL and TESL.

A lot of confusion exists around these terms and in particular the question of TESOL vs TEFL, which leads to a number of inevitable questions. You might ask…

  • Is one better than the other?
  • Do employers have a preference?
  • Are they the same?
  • How are they different?
  • Is one preferable to another in certain countries?

In looking at these various terms we will show that the idea of comparing one against the other, i.e. “TESOL vs TEFL” isn’t very helpful. So what do they mean?

TEFL:    Teaching English as a Foreign Language

When the English teaching takes place in a country where the predominant language is not English, such as teaching English in Germany or Japan.

TESL:    Teaching English as a Second Language

TESL (sometimes just ESL) applies when teaching English to non-native speakers of English in a country where English is the first language. Examples would be teaching English to Pakistani students in the UK or teaching non-native English-speaking students in an international school with an English curriculum.

While both the above terms are often used in a similar way, the next acronym puts both these terms under one umbrella:

TESOL:    Teaching English to Speakers of Other Languages

This combines TEFL and TESL/ESL. The students’ first language is not English, but the environment in which they are learning English is inconsequential.

The bottom line is that the two terms are used interchangeably throughout the English-teaching world, and we shouldn’t really think in terms of TESOL vs TEFL. However, some countries are more familiar with one term than the other, for example TESOL is more common in the USA and TEFL more widely used in the UK
