A Wealth of Experience

I recently completed my TEFL certification at Vantage Siam in Bangkok, and I honestly couldn't recommend it more highly. From day one, the course was engaging, practical, and incredibly well organised. It was challenging in all the right ways, but also a lot of fun.

The trainers—Chris, Kevin, and Ryan—were fantastic. They brought a wealth of real classroom experience to every session and genuinely wanted each trainee to succeed. Their feedback was detailed, encouraging, and always helped me improve, making even the toughest parts of the course feel achievable.

The course itself is very comprehensive. It takes you step by step through English grammar, vocabulary, lesson planning, and teaching methodology, giving you not only a solid understanding of the language but, more importantly, the confidence to teach it effectively. Everything you learn is reinforced through plenty of practical teaching experience.

During the course, I taught seven observed lessons lasting between 30 and 50 minutes to students ranging from kindergarten through to teenagers, across levels from CEFR Pre-A1 to B2. That amount of real classroom experience made a huge difference, and by the end of the course, I felt genuinely ready to walk into my own classroom.

The lesson planning support, detailed feedback, excellent facilities, and ongoing job assistance were all outstanding. You leave the course feeling well prepared, supported, and confident about starting your teaching career.

If you're thinking about taking a TEFL course in Bangkok, I wholeheartedly recommend Vantage Siam. It exceeded my expectations, and I'm incredibly glad I chose it. Five stars!

my Tefl experience at Vantage

I can honestly say this TEFL course exceeded my expectations. Even after 25 years of teaching, I learned so much that I can take into my own classroom. The course introduced me to different teaching methodologies and, more importantly, helped me understand why certain approaches work better in different situations. It definitely made me reflect on my own teaching and gave me new ideas that I can put into practice.

One of the things I really appreciated was the focus on Thai culture and the school environment. It wasn't just about learning how to teach English—it also prepared us for what it's actually like to live and work in Thailand. That insight has given me much more confidence about teaching in Thai schools.

The teaching practicums were incredibly valuable. They gave me a realistic idea of what to expect in the classroom, and the feedback after each session was constructive, and encouraging. Being able to put what we'd learned into practice and then receive guidance on how to improve made a real difference.

As a native English speaker, I was surprised by how much I learned about my own language. There were many grammar points and language features that I had never really thought about before because they come naturally to me. The course helped me understand how English works from a learner's perspective, which has made me feel far more confident about teaching it.

A big thank you to the instructors, who were highly knowledgeable, supportive, and genuinely invested in everyone's success. They created a positive learning environment where questions were always welcomed, and their regular feedback helped us grow in confidence throughout the course.

I would highly recommend this course to anyone thinking about teaching English in Thailand. Whether you're completely new to teaching or, like me, have years of classroom experience, you'll come away with practical skills, a deeper understanding of teaching English, and the confidence to step into the classroom.

An Incredible, Eye-Opening, and Highly Interactive Experience!

I had an amazing experience with Vantage TEFL Certification in Bangkok. From day one, the course was interactive, practical, and really well organized. It definitely lived up to all the positive reviews I had read beforehand.

One of the biggest highlights for me was Chris. His teaching style is energetic, engaging, and easy to follow. He has a real talent for explaining difficult concepts in a way that just makes sense, and he keeps the classroom fun and interactive throughout the course.

I also got so much value from the career preparation sessions with Kevin. Learning how to build a strong resume, create a PAR story (Problem, Actions, and Results), and even something as simple as sending a professional thank-you email after an interview completely changed the way I approach job applications. These were things I had never really thought about before, and they gave me a lot more confidence going into interviews.

What I appreciated most was that the course wasn't just about learning teaching theory. There were plenty of opportunities to put everything into practice, receive constructive feedback, and grow with each lesson. I finished the course feeling prepared and excited to start teaching.

If you're thinking about teaching English in Thailand-or anywhere else-I genuinely recommend Vantage TEFL. Whether you're completely new to teaching or looking to improve your skills, you'll leave with practical knowledge, confidence, and a great support team behind you.

From Learner to Confident Teacher

My journey with Vantage has been a transformative experience that shaped me into a more confident and capable teacher. The course didn’t just provide me with teaching techniques; it equipped me with the confidence, skills, and mindset needed to create meaningful learning experiences for students. Through practical sessions, observations, and continuous guidance from supportive trainers, I learned how to engage learners, adapt my teaching style, and step into the classroom with greater confidence. Vantage helped me discover my potential as an educator and gave me the foundation to become a better teacher every day. I’m truly grateful for the experience and the growth it brought to my teaching journey.

An Amazing Course!

I had an amazing experience learning at Vantage. Their training center feels like a home away from home, where people from different nationalities come together to learn and share ideas and experiences. And through their observed teaching practices, learn how to teach! For me, the practice teaching sessions were the highlight of the course--and how my classroom skills were developed.

It’s a very welcoming, supportive, and stimulating environment, and I thoroughly enjoyed my time there.

I highly recommend Vantage for anyone embarking in a new career in education.

Alumni Interviews

These are in-depth Q&A sessions with verified alumni.

Why did you choose this program?

I decided to do my TEFL when I was stuck in a dead end job with zero ambition. I looked at various way of traveling the world while earning some money and came across TEFL, and decided that I have nothing to lose and everything to gain. I love children and that is a main reason why I decided to do the TEFL.

What did your program provider assist you with, and what did you have to organize on your own?

I sent an email asking about the course and what it would entail. The institution (Vantage TEFL) I worked with had fast responses and answers to all my questions. They made it very easy to understand the requirements with constant feedback. I never had any doubt that I could do this through the confidence they gave me. A truly professional approach and I really enjoyed the journey of doing my TEFL.

What is one piece of advice you'd give to someone going on your program?

I moved to Thailand without doing any research about my surroundings and the cultural differences were the most challenging when I moved here, but people are so polite and friendly (it is contagious) that you adapt easily. I wish I knew about this earlier, as I would have loved to do this earlier in my life. Last piece of advice is to not underestimate the course as it was intense but enjoyable, and I truly believe, after this course I can teach English as a second language to anyone willing to learn.

What does an average day/week look like as a participant of this program?

My course was a 9:00 to 17:00 on weekdays for a month long. It is long days and sometimes you had to get the the facility at 07:00 to do practice teaching. On an average day, you are guided through the English language and it is not to teach you English it is to help you to teach English. You also get exposed to practice teaching, which really helps you gain confidence as an English teacher and removes all doubt you would have (I also had a lot of doubt and anxiety, but the practice teachings ensured that I gained confidence and became comfortable in teaching).

Going into your experience abroad, what was your biggest fear, and how did you overcome it? How did your views on the issue change?

Biggest fear I had was that I never left my hometown for more than 6 weeks before. I always thought how would I adapt to a place I do not know and people that I do not understand? To answer that question, the answer lies within yourself. You need to decide that you want to do this. Once you open yourself up to the idea, it is strange how things just fall into place through meeting amazing people and experiencing unique cultures.

I have no doubt this is one of the biggest changes I made in my life and I have no regrets that I did it. Sometimes fear dictates our decision making, but just think of all the amazing experiences you will have and be able to share with your friends and family when they come visit.

What do I think prospective travelers would like to know?

My answer will be based on Thailand, as this is where I am currently.

Firstly, food is absolutely amazing. I have gained so much weight just by indulging in Thai cuisine.

Secondly, make sure that, if you want to work here, that your employer can speak English where both parties understand to avoid unnecessary confusion.

What would I change or do differently?

I have not been here to long and I would say there is currently nothing I would change, as the experience has been challenging and breathtaking at the same time.

Last thing that I would say: do not run from you fears. Embrace them and just do it; you will not regret it.

Chris Demetsopoullos

Job Title
Lead TEFL Trainer
Headshot of staff

Chris, tell us about yourself.

Originally from the UK, I started my teaching career in the early 1990s where I taught a diverse range of Thai students. I then moved up to positions of corporate English assignments, which led to work as a developer of customized curriculums -- increasingly in digital eLearning materials -- for business skills courses and workshops.

Today, I specialize in one-on-one Executive Coaching for personal development programs and Leadership Coaching for Thailand’s blue chip corporations as well as being the Lead Trainer for Vantage’s TEFL program.

How have you changed/grown since working for your current company?

I have many years of business English teaching and corporate training with previous companies, along with training materials development.

However, I’ve really honed that skill with Vantage, as we offer customized corporate training programs — business English and management and corporate skills on an exclusive basis.

We specialize in blended learning programs, so a new and important skill I’ve developed is eLearning instructional design.

I’ve also become a teacher trainer since working at Vantage Siam, for which my experience and varied roles have been invaluable. Vantage has given me the opportunity to grow and develop professionally, and I’m sure there’s more to come.

What is the best story you’ve heard from a return student?

We had a recent trainee who had had a rather troubled past. He decided to essentially “grow up” and better himself by getting himself a respectable career.

He contacted us and, after meeting with him, we were pretty sure he could become a good English teacher. However, he had very little confidence that he could make it.

We soon discovered he was very good at drawing out language from the students by use of questions, prompts and cueing during the first phase of the ESA methodology (Engage, Study, and Activate).

With subsequent training in the Study and Activate phases -- along with observed teaching practices -- he became highly effective in delivering a class to non-English speaking students in a live classroom. In short, this ‘raw recruit” became a highly skilled teacher. The surprise was that we had no idea in the beginning how good he would turn out to be.

We then helped get him a good teaching position at a prestigious school that is very appreciative of the way he motivates his students into successful English language acquisition.

What makes your company unique? When were you especially proud of your team?

Vantage has always embraced the cutting edge in educational technology. We were among the first to offer customized courses in English for Special Purposes. We embraced eLearning and blended instruction in our classrooms in Thailand over fifteen years ago. We have been advocating computer-adaptive proficiency testing. Later this year, we will be educating the market in the first speaking and writing tests to be scored by AI technology.

And while we teach an American accredited TFFL course, we do supplement the curriculum with an introduction to both assessment methodology and emerging teaching technologies.

What do you believe to be the biggest factor in being a successful company?

I think one of the key factors in being successful is the ability to re-invent yourself -- or at least being open to change. And to change yourself effectively, you need to be able to hear what’s going on in the world around.

We like to think we’re good listeners. We listen to a couple of key voices to help point the company into head winds that we lead us to future successes.

We listen what the market is telling us in terms of what skills schools need for successful teachers.

We also hear what our TEFL candidates tell us during our time with us. We look at what skills they bring on day one --
what we do throughout the course -- and what the final product turned out to be. In other words, how well can they teach in a real classroom at the end of their training.

And finally, we follow key thought leaders in the education field. People that are talking today about what may be mainstream in learning tomorrow.
