What is TESOL?
TESOL stands for Teaching English to Speakers of Other Languages. It describes the professional practice of teaching English to learners whose first language is not English.
TESOL teachers help students develop the language skills they need for education, employment, travel and international communication.
You may also see the term TEFL (Teaching English as a Foreign Language). Both terms refer to teaching English to non-native speakers in schools, universities, language centres and online learning platforms.
TESOL teachers work in many contexts, including:
- Language schools
- Universities and colleges
- International schools
- Community education programmes
- Corporate training
- Online learning platforms
Why TESOL qualifications matter
English is one of the most widely used languages in the world. Learning English can open access to education, employment and international opportunities.
TESOL teachers support learners to develop the language skills they need to succeed.
A recognised TESOL qualification can help you:
- Teach English abroad
- Teach English online
- Work in language schools and universities
- Specialise in teaching young learners
- Progress into teacher training or academic management
Many employers require teachers to hold a recognised TESOL qualification with supervised teaching practice.
