Three Months of Thai Lessons Is Nothing and Everybody Is Surprised
The gap between knowing the tones and being able to hold a conversation is about two hundred hours, and a school can compress it, but not as much as the marketing says.
Everybody who studies Thai for a month believes they will be able to use it. Almost nobody can, and it is not because the language is impossible, it is because a month is about a hundred hours and a hundred hours is not a conversation.
That is the whole article, really, and everything else is detail.

What Thai actually is, and why it is the way it is
It is an isolating language, which means word order carries the grammar, so there is no conjugating verbs and no grammatical gender and no plural forms and no articles. That is a genuinely easier grammar than a European language and it is the one thing Thai learners consistently underestimate.
It is tonal, which means the same syllable can be a different word entirely depending on the pitch contour, and getting the tone wrong can change the meaning in a way that is not funny and is occasionally the opposite of what you meant.
And it has no word for most of the concepts that make English heavy, which is why Thai is often described as having fewer words and it actually has more. The count is different because the counting system is different.
The hundred hour rule
Two hundred hours gets you to a genuine basic conversation, on a specific subject, slowly, with mistakes. That is the number most reputable schools use and it is roughly what the Foreign Service Training Program and comparable programmes assume.
A hundred hours gets you functional in a specific context. You can order, you can ask where things are, you can buy a ticket, you can handle a taxi. You cannot handle a conversation where somebody tells you something you did not expect.
A month of full-time study is about a hundred and twenty hours, and the honest expectation after it is that you will recognise a great deal, order a great deal, and speak very little.
And most of that knowledge decays at a rate people do not expect. A hundred hours of study six months ago is worth maybe half of what it was. The retention curve is the reason people conclude the school was bad when it was not.
One to one or group
One to one is three times the price and roughly twice the value per hour, early on, because you are speaking for most of the lesson instead of watching other people speak and waiting.
Group classes are better after the first two hundred hours, when the problem stops being "can I make a sound" and becomes "can I keep going when I do not understand", and you need other people to keep going against.
The most common mistake is starting with one to one for a month, because it feels productive and you leave able to converse with a teacher who was paid to be patient with you.
What to study first
Tone pairs, and the four sentence tones, and the fact that mid tone is not optional. Every word has a tone. Ignoring this is the mistake that costs people a year.
Then the polite particles, which carry most of the social information in the language. Krap and ka do an enormous amount of work and are almost always used.
Then numbers, which you already partly have from the price system, and dates and times, because a country is navigable as soon as you can read a timetable.
And then about a hundred nouns, plus the verbs to eat, go, buy and ask. That is a starter vocabulary, not a course, and it will carry you a long way.
Choosing a school
Look for a school that is large and busy, because a small school with ten students and a friendly owner is usually a school with two teachers who are teaching at their level rather than yours.
Ask what the teacher to student ratio actually is, and ask to sit in on a lesson before you pay. Both are reasonable requests and a good school will agree immediately.
Ask whether teachers are native speakers with a recognised teaching qualification, which is a different thing from a native speaker, and a big difference.
And check the class schedule matches your life, because the best school in the country is the one whose timetable you can actually get to, and everybody makes this decision based on reputation rather than geography.
Where, and what kind of trip
Chiang Mai has the most schools and the strongest infrastructure for this, and it is a good place to do a long course because the city is cheap, the food is good, and you are among other people doing the same thing.
Bangkok has the best schools for absolute beginners who want to be in the capital, and it is a worse place to spend three months studying because the city is distracting and expensive.
Pai has schools and a specific atmosphere that suits people who want a quiet, cheap, cold place to study, and it is a genuinely different experience from either of the other two.
And there is a fourth option that is the best one for a lot of people: three months of two hours a day at home. It is slower in total hours and it is the version you will still remember in five years, because you used it on the second day you arrived instead of on the last day before you flew home.
