We asked a simple question in the international teaching community: looking back, what advice would you give yourself as a beginner international teacher?

More than fifty educators answered — some with two decades abroad behind them, some just a few years in. What came back wasn’t the usual glossy “follow your dreams” encouragement. It was honest, specific, occasionally blunt, and genuinely useful.

We’ve pulled the responses together into the themes that came up again and again. If you’re about to sign your first international contract, or you’re still deciding whether to leap, this is the advice experienced teachers wish someone had given them.

1. Research the leadership before you research anything else

The single most repeated warning had nothing to do with salary or location. It was about who runs the school.

Experienced teachers described a profession where school culture is set almost entirely at the top, and where a certain kind of leader — someone who climbed fast, without much classroom experience — is treated as a red flag. The recurring advice: look up the leadership team on LinkedIn before you apply. If the people running the school became leaders after only two or three years in the classroom, teaching subjects unrelated to what they now oversee, take it as a warning sign.

The phrase one veteran used stuck with a lot of commenters: a school like that isn’t really a school. It’s something else wearing a school’s clothes.

2. It’s a small world, and your reputation travels

Over and over, teachers described the international circuit as far smaller than its 10,000-plus schools would suggest. Wherever you go, you’ll eventually meet someone who worked with someone you worked with. Word gets around.

The practical takeaways were consistent:

• Leave every school on good terms, even one you disliked. Finish your contract, don’t burn bridges, don’t leave a trail of angry emails.
• Be mindful that references travel informally as well as formally — a casual conversation between two heads of school can matter as much as a written reference.
• Keep in touch with recruiters and former colleagues. Several teachers specifically recommended keeping a recruiting agency profile active even when you’re not job-hunting, because things can change fast.

3. Observe first. Speak later.

One of the most upvoted pieces of advice was about your first year specifically: watch before you act.

Experienced teachers advised new arrivals to resist the urge to share ideas and make sweeping suggestions in the first months. Instead, spend that time reading the room — noticing the cliques, the informal power structures, who actually gets things done, and where the tension sits. Get involved and be supportive, but treat the first year as the year you learn how the place really works. Several teachers said this instinct had genuinely protected their jobs down the line.

4. Talk to people on the ground, not YouTube

A striking number of teachers warned against relying on polished online content to understand a country. The advice was to find real people who actually live where you’re going, and ask them the unglamorous questions: what are the day-to-day norms, the local laws, the scams that target newcomers, the things your school won’t mention in an interview.

One teacher shared a hard lesson — losing an entire month’s salary to a scammer posing as police in their first weeks, something a single conversation with an experienced expat could have prevented. The theme was clear: the information that protects you usually comes from people, not marketing.

5. Think about money, but don’t let it run your life

This was the theme with the most internal debate, and it’s worth presenting both sides because the community didn’t fully agree.

The financial-discipline camp was firm: start saving from your first paycheck, invest consistently in globally diversified index funds, and take advantage of “geographic arbitrage” — choosing higher-saving locations early in your career so you have freedom of choice later. Several credited this approach with the ability to retire a decade earlier than colleagues who never invested. A commonly recommended starting point for the financial side was Andrew Hallam’s writing on expat investing.

The counterpoint camp pushed back and got just as much support: it’s easy in this profession to treat savings as the only measure of success, and that’s a trap. You can work a few extra years for more money at the end of your career — but you can’t go back and redo your twenties and thirties. Making friends, finding a partner, building a life, and actually enjoying where you are all matter. The happiest teachers weren’t always the ones who earned the most.

The synthesis most people seemed to land on: be financially disciplined and deliberate about quality of life. Neither one alone is the answer

6. Never stop building your CV

Upskilling came up constantly. Teachers who invested in extra qualifications — additional certifications, IB training, weekend professional development — described it as directly moving them from lower-tier to higher-tier schools.

One useful nuance emerged in the replies, though: several experienced teachers cautioned against paying out of pocket for expensive qualifications like IB workshops. Good schools, they said, will often hire you without prior IB experience and pay for the training themselves. So upskill relentlessly — but be strategic about what you pay for versus what you let an employer fund.

7. Protect your wellbeing and your boundaries

A quieter but persistent theme was that this career can quietly grind you down if you let it.

The advice here was practical and human:

• Homesickness is real, especially early on. Find your people, build a community outside of just your coworkers, and don’t make permanent decisions based on a temporary low.
• Set boundaries around your time. In international schools, it’s easy to be pulled into endless extra commitments — learn to say no.
• Keep your private life private, and be cautious about becoming too personally entangled with the school.
• Have a fallback. Several teachers recommended keeping a modest side skill or income stream, and somewhere you could go if a job ends suddenly, because in this profession, sometimes it does.

8. Know when to walk away

Finally, a theme that ran through many of the most upvoted comments: trust your read on a place, and don’t be afraid to leave.

If a school doesn’t feel right, finish your contract and move on rather than trying to fix a culture set from above. If you’re not paid what you agreed on, treat it seriously. As one teacher put it simply, “No” is a complete sentence. Knowing your worth and being willing to remove yourself from a genuinely toxic environment was framed not as giving up but as basic professional self-preservation.
