Today I had a Thai language lesson with Dr Ying. The lesson was delivered in an up beat and friendly manner and the target material was delivered highly effectively. I probably learnt more Thai in one lesson than I have in several self guided efforts.

Dr. Ying使用了語言教學當中的PPP教學方法,在使用全泰語的課程環境當中,學生能夠跟著她的講解與步驟進行課程。 這堂課之後我非常能夠有自信地說,我能夠使用泰語進行點飲料(order drinks)了。

Dr. Yang gave me the courage to learn thai. She was determined to make us learn thai in three days and definitely did it in the best way possible. I was very impressed and enjoyed thai classes with her. Thank you very much Dr. Yang

As part of my TEFL course we had 3 hours of lessons with a Thai teacher. The final hour lesson was a fully immersive lesson where we learned how to order drinks. Non of the material was from the previous 2 hours. So from having no knowledge of the subject the whole class agreed that they could confidently order drinks in Thai. Dr Ying's method and instruction was very good especially as she got 16 non Thai speakers with no previous knowledge of the subject to be able to confidently speak Thai.

I really enjoyed these lessons!!! I was impressed with how much I learned in such a short time! But I also really liked that we learned more about Thai culture during the first two lessons! I really liked that!

As part of my EFL Training, I had the pleasure of receiving some basic Thai language instruction and cultural awareness from Dr. Ying Quinn. She is so warm and joyful, it was really fun learning from her, plus she has inspired me to pursue deeper learning of this beautiful language in the future.

I had the pleasure and honour to attend classes with the wonderful Dr Ying Quinn. I was amazed at what was accomplished in a short time. I learnt that respect (3 levels) is embedded in the culture of Thailand. We were taught about the 5 tones and practiced how they sound. Then, we went through some fun games with the different words and tones and learned a simple sentence structure.. by the end of the lesson, I feel confident I could order my drink of choice at a cafe or bar in a polite manner… I am so impressed with the Teacher and her methods. I would recommend 100% and hope to learn more Thai with Dr Quinn as soon as possible. ขอบคุณมากครับ

Myself and my wife Rajni had a truly effective and thoroughly enjoyable review doing the Beginners Thai lessons for the past few months. Our teacher Kru Oil was an amazingly accomplished instructor. She was extreme patient, clear and engaging. We had a small group, so the classes were very interesting, with much learning about Thai culture, customs and cuisine etc along with the language skills! Overall a very satisfactory and enjoyable way to commence our efforts to learn Thai. 👍😀💥

The school was professional all around. The staff were great at helping us stay on top of our visa paperwork and class schedule; very organized and excellent in their bilingual or multilingual abilities. The teachers were well organized, yet flexible and willing to tailor lessons to students' needs and ability levels. Teaching methods and content were given from a variety of approaches and content. I would recommend the school to anyone serious about learning the language and culture.

My husband and I took Thai language lessons with Effective Thai Chiang Mai throughout our first year of living in Chiang Mai. I was very nervous learning such a foreign language, but with the family classroom option, it was just my husband and me and the instructor. When we traveled — which was often — our classes were simply paused until our return. The flexibility was so appreciated. We were able to learn at our own pace and at our own learning style. Everyone at Effective Thai Chiang Mai is so warm and accommodating. We literally started classes within a week of moving here. The whole school has such a friendly atmosphere, and it’s so clean and comfortable. It was a wonderful welcome to Chiang Mai. We made many friends our first week, many that were taking Thai language classes like us, or were enrolled in their SEE TEFL certification program. Because we were on a Thai language visa our first year, the school went above and beyond to help make that process as smooth as possible. We are so very thankful that we made the choice with this school!

Excellent Effective Thai course. There were three students on my course, which was a lovely small group. Teacher View was very good and very patient. We were taught speaking, writing and reading, I especially enjoyed the reading and writing and have booked a further course to progress further with this very intriguing language, Thank you Effective Thai for a wonderful course.
