What is the difference between a TESOL, TEFL, TESL, ESL, ELT, ESOL teaching certificate?
TESOL: Teaching English to Speakers of Other Languages
TEFL: Teaching English as a Foreign Language
TESL: Teaching English as a Second Language
ESL: English as a Second Language
ELT: English Language Teaching
ESOL: English for Speakers of Other Languages
Nothing! All of these acronyms stand for teaching English to students from or in non-English speaking countries.
Internationally there is no ‘one’ acronym for this vast industry and so colleges and organizations’ from the many, different English speaking countries created their own acronym.
A certificate with any of the above acronyms would be recognized for teaching English as a second language internationally.
What is important, is that any course you undertake to teach English as a second language be 120 hrs+, contain a methodology, lesson planning, grammar, classroom management, communication and many other modules.
In addition, schools and colleges overseas look for teachers who have completed face-to-face training (in-class or online ‘live’) and a teaching practicum with actual international students, in their TESOL course.
