TEFL / TESOL Certification for K-12 Teaching jobs in Thailand

The minimum TESOL certification requirement for English teaching jobs in Thai public schools, International Schools, or private after-school English classes is a 120-hour TEFL / TESOL certificate; however, aiming for the minimum requirements may not the best option in terms of job opportunities and job satisfaction. 

One of the challenges of entry-level K-12 jobs in Thailand is that classes tend to be large, with a minimum of 25 and a maximum of 50 students.

FAQs TEFL / TESOL Certification Thailand

How Does OnTESOL Compare with CELTA?

The UK-based CELTA certification course does not offer comprehensive training in lesson planning. Their main focus is the Practicum and lesson planning is introduced lightly in preparation for this module. The 120-hour and 168-hour TEFL / TESOL certification courses offered by OnTESOL include 3 lesson planning Lab Assignments that will prepare you to use a variety of communicative and task-based lesson planning frameworks in Thailand and internationally.

Should I Take the Cheapest TEFL / TESOL Certification for Thailand? 

Cheap online TEFL courses under $200 may get you an entry-level teaching job in Thailand because they only serve to tick a box on the work visa application, but they won’t prepare you much for the classroom. This is because cheap online TEFL / TESOL certification courses asses their trainees through quick multiple-choice assignments or reflection essays instead of giving trainees the opportunity to practice the ESL lesson planning frameworks they need to become a successful ESL teacher in Thailand. 

Do I Need to Renew My TEFL / TESOL Certification If I Don’t Want to Teach in Thailand Forever? 

Your OnTESOL credential will be valid for life. You can use it to teach English abroad anywhere you want to go, and it’s also valid for teaching jobs in native English-speaking countries such as Canada and the United States.

“My tutor was extremely supportive in giving constructive criticism that was very beneficial for my professional growth as a teacher. She also gave me many ideas for extending lessons and introducing further materials for students. I feel that my career as an international teacher has been boosted with new confidence.”
