Teaching in Thailand: 5 Challenges I Faced in a Thai Public School

I was not wrong about what frustrated me.

Classes started late. Students talked through lessons. Grades changed in ways I did not understand. Classroom rules could be undercut. Foreign staff sometimes learned important information after everyone else seemed to know it.

Where I was younger was in assuming the explanation for all of that was obvious.

I taught in Thailand for five years, which was long enough to learn that being irritated by something and understanding it are not the same skill.

If you want the practical side of the job first, including salary, school calendars, visas, and travel, start with my main guide to teaching in Thailand.

1. The Clock Was More Negotiable Than I Expected

If class was scheduled for noon, I expected class to begin at noon.

At my school, that was often more of a target than a guarantee.

• A 12:00 class might begin at 12:10 or 12:15.
• A school activity could rearrange the day.
• Students might still be coming from another activity.
• A schedule could change without everyone treating the change like a crisis.

I was the one treating it like a crisis.

I had grown up thinking punctuality was part of professionalism, so I often read flexibility as disorganization.

Years later, I can see another interpretation: a looser relationship with the timetable could feel normal, forgiving, or practical to someone else.

2. Classroom Management Was Harder When Students Could Not Understand Me

My students talked.

A lot.

I could get the room quiet, turn toward the board, and hear conversations start behind me again.

At 23, I saw that mostly as a classroom-management problem.

That was only part of it.

I was teaching science in English inside a Thai public school. Some students could follow comfortably. Others were trying to learn a difficult subject in a language they barely understood.

For those students, a 40- or 50-minute lesson could become endurance rather than learning.

Understanding that did not magically make the classroom quiet. It did make my interpretation more accurate.

3. The Grade I Entered Was Not Always the Grade That Stayed

This was one of the harder adjustments for me.

At my school, a student could do very little work, submit almost nothing, or sleep through much of class and still finish the term with a passing result.

At 23, I saw that mainly as a question of standards.

With more distance, I can see that grading sits inside a larger system:

• students and families are affected by failure
• teachers have institutional expectations
• schools have statistics and progression targets
• administrators may be balancing pressures I never saw from my classroom

I still cannot tell you exactly which pressures shaped every decision at my school.

The academic gaps were real. Some students were ready for the material. Others struggled to read basic English. Moving everyone forward did not make those differences disappear.

My younger mistake was not noticing the problem. It was assuming the policy could only have one explanation.

4. Being Responsible for a Classroom Did Not Always Mean Having the Final Say

One day, I assigned seats.

The next day, everyone had moved.

The students told me another teacher had said they did not need to follow my seating chart.

She had not discussed it with me first.

I was furious.

The issue was not really the chairs. I thought I had been given responsibility for classroom management and then learned that my authority could be overridden without a conversation.

I still think that was poor communication.

What I would not do now is turn one coworker's choice into a grand theory about Thai teachers or Thai culture.

One coworker made one decision that made my job harder. That experience was enough on its own.

5. Foreign Staff Were Sometimes the Last to Know

I expected some information to get lost across a language barrier.

I was working in a Thai institution. English was not the dominant language. I was the foreign employee.

What frustrated me were the moments when important information existed, English-speaking staff knew it, and foreign teachers still found out late.

• a schedule changed
• an event appeared
• a responsibility shifted
• someone eventually told us

Eventually was doing a lot of work.

With hindsight, I also understand that I was standing at the edge of an institution built to function in Thai.

I was not at the center of its communication system, even when my job sometimes made me feel as though I should be.

That did not make late information less inconvenient. It did make the bigger picture easier to see.

My Coworkers Were Not Nearly as Bothered as I Was

This is one of the most useful things I understand differently now.

My Filipino coworkers noticed many of the same frustrations I did. If I asked, they had opinions.

But most of the time, they seemed much better at letting an irritation remain small.

I do not know exactly why. I did not ask enough questions then to separate personality, culture, money, family obligations, job security, or simple temperament.

What I can say is that they seemed to spend less emotional energy replaying the problem.

If a schedule changed, I wanted to know why.

If a classroom rule was overridden, I replayed it.

If communication was messy, I wanted the system fixed.

Some of my coworkers appeared much better at deciding which problems deserved their energy.

That was a skill I had not developed yet.

It also connects to something I wrote about in Living in Thailand as a Woman of Color: working somewhere teaches you things about hierarchy, professionalism, belonging, and daily life that a short visit rarely exposes.

“Teaching in Thailand” Is Not One Job

Another mistake I made when I was younger was talking about teaching in Thailand as though one workplace represented the entire country.

It did not.

We could all say we were “teaching in Thailand.”

We were not doing the same job.

The older I get, the less useful I find the question “What is teaching in Thailand like?” without immediately adding: at what kind of school, in what role, and with what expectations?

Teaching Back Home Is Not Exactly Paradise Either

There is a temptation when describing frustrations abroad to imagine that the version of the profession back home is somehow the neutral one.

It is not.

U.S. teachers also deal with institutional pressure, paperwork, long hours, burnout, large classes, and administrative demands.

I include that comparison for one reason:

The alternative to an imperfect workplace abroad is not an imaginary perfect workplace at home.

The useful question is which tradeoffs matter to you, which problems you can tolerate, and what the job gives you in return.

I Did Not Love Everything About the Job. I Loved What the Job Made Possible.

This is the part my original complaint list could not hold very well.

I did not love everything about the job.

I loved what the job made possible.

• a regular monthly income
• a stable home base in Thailand
• a school calendar with predictable breaks
• weekends close to beaches, islands, and other parts of southern Thailand
• a way to build travel into life without becoming a digital nomad

These were not always school-break trips. Sometimes this was the geography around an ordinary work week.

I could finish a frustrating day and still live somewhere where beaches, islands, boats, festivals, and sunsets were part of the week instead of one annual vacation.

That is why I keep pushing back on the idea that remote work is the only way to build a life with travel.

A stationary job abroad can change the distances, costs, and calendar around you. Mine did.

If You Are Considering Teaching in Thailand, Ask Better Questions

I would not use one person's complaint list to decide whether you should teach in Thailand.

I would use it to build better questions.

• What kind of school is it? Public, private, international, language center, or tutoring program?
• How strict is the timetable?
• How are grades handled?
• Who has final authority over classroom rules?
• How are foreign teachers included in staff communication?
• What happens when plans change?
• How much vacation time is actually usable?
• What support exists for visas, work permits, and teacher documentation?

Those answers will tell you far more than a generic promise that teaching in Thailand is either amazing or terrible.

If Christmas matters to you, ask about that specifically too. Christmas in Thailand was not automatically a school holiday for me.

Do You Need a TEFL or TESOL Certificate to Teach in Thailand?

Not for every role.

Requirements vary by employer and the kind of teaching you want to do.

My later position was teaching science, so my academic background mattered more to that job than an English-teaching certificate.

If you are looking at English-teaching roles, a TEFL or TESOL course can still be useful, especially if you have little classroom experience.

I would care less about the acronym and more about whether the course includes:

• supervised teaching practice
• observation and useful feedback
• experienced trainers
• clear assessment standards
• recognition by the kinds of schools where you hope to work

For current Thailand-specific teaching vacancies, Ajarn.com remains a useful job board.

For immigration and employment documentation, use current information from the Thailand Ministry of Foreign Affairs and the school hiring you rather than assuming a previous teacher's paperwork will match yours.
