TEFL Certification

Having English-teaching certification is a door opener.  Some schools require it and others give preference to candidates with certification.  Not only does having ESL teaching certification makes you more attractive as a candidate, it also ensures a certain standard of teaching knowledge and prepares you for a career in English teaching with hands-on practice developing lesson plans and teaching in a classroom environment.

TEFL/TESOL/CELTA certificates are MANDATORY for all applicants who want to apply for public schools in South Korea except teachers who have a Bachelor’s or Master’s in Education or a teaching license or graduated with a major in Teaching, TESOL, Second Language Studies, or any field of Education (Physical Education, Math Education etc.). A 20-hour in-class component is recommended by the Korean public schools.

Private schools in South Korea also prefer applicants who have completed at least 100 hour of TEFL, TESOL, TESL or CELTA courses.

To secure a great job with a reliable and reputable school, TEFL certification is one of what you will need.


TEFL, TESL, TESOL, CELTA could be quite confusing. These acronyms are often used interchangeably. Here is a breakdown of their specific meaning:

TEFL (Teaching English as a Foreign Language) refers to teaching English to students whose first language is not English.

TESL (Teaching English as a Second Language) refers to teaching English to students whose first language is not English, usually offered in a region where English is the dominant language and natural English language immersion situations are apt to be plentiful.

TESOL (Teaching English to Speakers of Other Languages) This encompasses TEFL and TESL and can mean either one or both. The course prepares a teacher to teach a student whose native language isn’t English and who may know other languages in addition to his or her native one, meaning that English might be the student’s third or fourth language.

CELTA (Certificate in Teaching English to Speakers of Other Languages)  is an initial teacher training qualification for teaching English as a second or foreign language (ESL and EFL). It is provided by Cambridge English Language Assessment through authorised Cambridge English Teaching Qualification centres and can be taken either full-time or part-time. CELTA was developed to be suitable both for those interested in Teaching English as a Foreign Language (TEFL) and for Teaching English as a Second Language (TESOL).
