Course Reviews: 120-hour Advanced TESOL Certificate


“I found the 120-hour TESOL certificate program challenging and rewarding. This course allowed me to gain a proper understanding of the concepts and methods that work in the ESL classroom. This TESOL course helped me to better organize my classes and ultimately benefit my students”.

Erik Sorenson

Teaching in South Korea

My 120-hours OnTESOL course was an effective, efficient, and high-quality expenditure of my time and money. My instructor was easy to communicate with, responsive, and provided in-depth feedback that was entirely specific to my work. I appreciated the time and effort that she put into providing me with feedback. Since completing this certificate, I have had steady work as an ESL instructor at various post-secondary institutions in Canada. I have recommended OnTESOL’s program to my friends and will continue to recommend it to anyone who is interested in TESL certification.


Teaching in Canada

The lesson planning assignments and reflection essays challenged me to think about what I would actually do if I were in a classroom, making the learning experience all that more experiential. The online course prepared me really well for the Practicum and my tutor provided me with invaluable support as he shared his own personal perspective on teaching and how he structures his lessons.

Frequently Asked Questions

What is an Advanced TESOL Course?

The minimum requirement for teaching jobs is a 120-hour TESOL / TEFL / TESL certificate, but not every course is built the same way.

Most online TESOL courses offer introductory training and lack the necessary training to pursue a career in Education. They assess students via quick reflection essays and multiple choice questions. Some courses cover lesson planning in the materials but don’t offer assignments to teach how to write a CLT-based lesson plan. Furthermore, most introductory courses lack grammar and phonology modules.

An advanced TESOL certification program offers comprehensive training in every area of TESOL theory and methodology: grammar, phonology, and methodology. In particular, an advanced TESOL course assesses trainees through major lesson planning assignments that integrate grammar and vocabulary lessons with speaking, writing, reading, and listening skills.

An advanced TESOL course is generally accredited by one of the top 3 accrediting bodies in the world: TESL Canada, Trinity CertTESOL, and/or CELTA. These organizations check the course material, level of assignments, and tutor support to ensure trainees receive professional training. Courses accredited by one of the 3 major bodies are considered advanced because the course material and level of assignments are very comprehensive. By the end of an accredited program, students have the advanced lesson planning skills they need to adapt to any curriculum in the world.

How long do I have to complete the 120-hour TESOL Certificate course?

This online TESOL course was designed for trainees who need to take a TESOL certificate course at their own pace in order to meet other work or study commitments. The minimum time necessary to complete this online TESOL program is 4 weeks. The maximum time given to complete this course is 6 months.

Do I need a university degree to take this course?

No. We welcome applicants from a variety of backgrounds. Most of our students have a degree but others are either at College or University or they do not have any formal qualifications beyond a high school diploma. However, most employers require applicants to have a degree and in most countries a degree is necessary to obtain a work permit.

It is important to highlight that if you are interested in applying for a TESL Canada Professional Certificate, you must hold a university degree or equivalent.
