FAQ 1: How Do I Choose The Best TEFL / TESL / TESOL Certification Course?
The best TESOL / TEFL / TESL course will teach you the most common methodologies and lesson planning formats to develop your capacity to adapt to different teaching materials and groups of learners.
Knowing how to supplement the textbook with communicative activities and authentic material (Ei: songs, movies, news stories, podcasts, and other media) is a very important skill that you must have as an ESL teacher. Whether you are planning to teach English abroad, in an English immersion program at home, or teach English online, the textbook is often outdated and boring. In some countries, there isn’t even a textbook to follow because students cannot afford one.
How Does OnTESOL Offer the Best Training?
Most courses out there offer an introduction to TESOL / TEFL / TESL methodology. This means that they introduce the topic of lesson planning but they do not assess their trainees via lesson planning assignments that follow the international formats (Ei: PPP, TBL, ESA, etc). Some courses do not even require trainees to create a single lesson plan and they assess via reflection essays and multiple-choice tests only.
After completing your advanced TESOL course with OnTESOL, you will be able to create fun and effective lesson plans using your own authentic materials, integrate skills activities, role-playing, simulations, drama, storytelling, debating techniques, presentations, and many more CLT strategies and techniques.
Our advanced TESOL courses also include a comprehensive grammar and phonology module that will test your knowledge and serve you as a reference throughout your teaching career.

TEACH ENGLISH ABROAD
TEACHING ABROAD VS TEACHING IMMERSION PROGRAMS AT HOME
Teaching abroad is a great way to travel the world while doing a job that makes a difference in the lives of many people. Most people teach English abroad for a year or two, but there are plenty of highly paid job opportunities in native-English countries, so there are thousands of teachers who continue their TESOL career at home or keep traveling around the world. The advanced TESOL courses offered by OnTESOL provide great flexibility to native-English speakers from Canada, USA, UK, Ireland, Australia, New Zealand, and South Africa who want a credential that is accepted abroad and also at home.
TESOL COURSE REVIEWS
REVIEWS BY ONTESOL GRADUATES
I had a very accommodating tutor named Danielle. Though we didn’t get to see other, I felt very comfortable with her. I value and really appreciate her efforts and time on checking my assignments, especially when I was having trouble in making a lesson plan. I learned so much with my tutor. The ideas that she shared had been a great help in my class. Thank you for the great experience OnTESOL!
Teresa Legria – Teaching English in South Korea
The course was really helpful and beneficial. I have been an ESL for 3 years but I still learned a lot and I am now a much more effective teacher. I finished the course feeling more confident because I am better equipped after in taking the 120-hour TESOL certificate course with OnTESOL. Furthermore, the tutors are great. They encourage you to ask questions and they also provide lots of comments and feedback. They are really committed in your learning. Choosing OnTESOL is a very good decision!
Michelle Chavez – Teaching English in Thailand
Even after completing a Bachelor of Education, Master’s Degree in Educational Psychology with a thesis on English Language Learner Achievement, two years teaching in South Korean international schools and five years teaching in Canadian public secondary schools, which includes international programming, I found OnTESOL’s program incredibly useful, relevant, theoretically sound and pedagogically inspiring. Not only is this program fundamental for those who wish to teach abroad, but it is also practical and helpful for teachers working with international students who need greater insight into linguistic development, language learner needs and adapted teaching strategies.

TEFL / TESOL / TESL CERTIFICATION
AND TEACHING ENGLISH ABROAD
IS TEACHING EXPERIENCE REQUIRED TO TEACH ENGLISH ABROAD?
Teaching experience is not required to teach English abroad. Teaching experience may be required in native-English speaking countries, the Middle East, and Hong Kong, where teachers earn up to $70,000/year plus benefits.
DO I NEED TO LEARN A NEW LANGUAGE TO TEACH ENGLISH ABROAD?
You don’t need to speak the local language to teach English abroad, but you should take advantage of your TESL experience to learn a new language for your own personal development. The English-only policy prevails in most programs and schools want certified teachers who know how to use the Communicative Approach. Our TESOL courses will prepare you for the job.
HOW IS ONTESOL DIFFERENT?
Most course providers offer introductory TESOL courses for people who just want to teach English abroad and travel. Even CELTA is an introductory program for entry-level teachers. Our goal is to raise the standards of the industry by providing professional teacher training programs that are accredited and affordable. Learn more about us
HOW DOES ONTESOL COMPARE WITH CELTA?
CELTA is an entry-level 120-hour TESL / TEFL / TESOL certification course that includes a Practicum module. OnTESOL offers advanced online TESOL courses with an optional Practicum module that is offered separately. Our 120-hour Advanced TESOL Certificate is academically equivalent to CELTA. Our 250-hour TESOL Diploma is more comprehensive than the CELTA certification course. Graduates who wish to gain supervised teaching experience can take the 20-hour Practicum module anywhere in the world.
DOES ONTESOL PROVIDE TUTOR SUPPORT?
All our TESOL courses come with professional tutor support! An experienced and accredited teacher trainer will assist you throughout the program and provide you with extensive feedback on every assignment.
IS ONLINE TEFL / TESOL CERTIFICATION ACCEPTED WORLDWIDE?
In most countries, the minimum TEFL / TESOL certification requirement is 100 hours. If your goal is to teach English abroad, you can get an entry-level job anywhere in the world with an online TESOL or TEFL course. If you want to teach English in a native-speaking country, you need to complete a 20-hour Practicum module after the online course. The Practicum module is also recommended for certain teach abroad programs in Hong Kong and the Middle East. OnTESOL graduates can complete an optional Practicum module after completing any of our advanced TESOL certificate courses.
HOW DOES THE PRACTICUM WORK?
You can take the Practicum module anywhere in the world after completing any of our advanced TESOL courses (The Practicum is not available for TEFL certificate graduates). The Practicum must take place with adult students, as per TESL Canada requirements. Graduates are required to find a qualified supervising teacher and OnTESOL will provide the guidelines after we approve the supervising teacher.
