Small Group Thai Language Classes

Small Group Thai Language Classes

Our Small Group language classes are much more effective than larger classes of 10 students or more, common at other Thai Language schools. Great for families or friends who want to study together. 

1-to-1 Thai Language Classes

Thai Language Classes are most effective with 1-to-1 tutoring. While it costs twice as much as the small group rate, the speed of learning can be twice as fast. For students who are advancing beyond the basics, this is the best approach. Students have different strengths and areas for improvement, different interests and learning styles. 1-to-1 is the best approach, including a flexible schedule.

  • We have 1-to-1 Thai language classes available to begin at any time
  • 1-to-1 courses are in bundles of 10, 25, 50, 100, 200 lessons (each lesson 50 minutes)
  • Deposit Payments (50%) to secure a place via PayPal, bank transfer, credit card, and cash.
  • Balance Payments should be completed by the end of the first day of study.

Small Group Thai Language Classes (2-6 students)

Our Small Group language classes are much more effective than larger classes of 10 students or more, common at other Thai Language schools. Great for families or friends who want to study together. If the students create their own group, they can choose study dates/times convenient to them.

  • We have new small group language classes starting each month

EXCLUSIVE TAILOR-MADE THAI LANGUAGE CLASSES

Effective Thai students are exposed to authentic Thai language and culture inside and outside the classroom. The goals of the program are to develop careful listening skills, cultural and linguistic awareness, and interest in real Thai society, as well as to learn essential and modern words and phrases used in Thailand.

What do we offer that is very different and exclusive from the rest?
  • Individual tailored courses that focus on your exact needs and in the manner in which you learn most effectively.
  • Learn the art of dealing with difficult situations in an intelligent and pleasant manner specific to Thai culture.
  • Enable you to make a considerable impression in all aspects of Thai society.
  • Access to our highly qualified and wide network to practice Thai, make connections, and develop future opportunities.
  • Do you want to develop strong professional and/or personal relationships? Improving all four disciplines (reading, writing, Speaking, and listening) of any language is key to overall comprehension. These disciplines are essential to nurturing relationships in Thailand, be they for business or pleasure, and Effective Thai prides itself on preparing our clients to exceed those expectations.
  • Language of influence
    In addition to improving your language proficiency, we teach you how to gain clear advantages by ‘reading’ distinctly Thai situations, enabling you to communicate the perfect response. Knowing the ‘how and when’-the exact phrase at the most precise time-is often the difference between communicating in Thai and Effective Thai. We are the latter.
  • Corporate Training  is an exclusive tailor-made program at Effective Thai for corporate training.

The course is not for everyone; it takes commitment and desire, which is best-suited to goal-orientated people. Effective Thai Language is a unique experience for those who are willing and eager to not only improve their language proficiency but who want to understand, and be effective within, sophisticated Thai culture. The course is targeted for people who wish to make connections with all types of Thai people with an emphasis on developing meaningful personal and professional relationships.
