A public school is a good option for a family that wants to introduce their child to the local education system. Not an international one, but a regular one. Here the child studies alongside local students. And is immediately immersed in the language and culture of the country.
That said, admission conditions, age requirements, the curriculum, and opportunities for foreigners differ. Across different countries. And even across different regions of the same country. So a school should be chosen not just on the principle of "public or private." You need to look at the child's specific situation.

Public schools operate according to national standards. The curriculum includes compulsory subjects. And in the upper grades, additional disciplines and tracks appear. That the student chooses themselves. Depending on their interests and plans.
A separate question is the language of instruction. For a foreign child, this is both an advantage and a challenge at the same time. Constant communication with native speakers helps them adapt faster. But in the first few months, studying can be hard.
The main advantage of a public school abroad is that the language is used not only in class. But also in ordinary school life. The child chats with classmates. Works on group projects. Attends extracurricular activities and clubs.
If the child's language skills aren't yet enough for normal studying — find out in advance whether the school or region offers additional language support for foreigners. In some systems, there are special classes or adaptation programs for this.
It's not just about the price. Public schools are part of the national system. They operate by rules set by the state. Private ones usually offer more program options. And may have their own approaches to teaching.
The specific conditions vary greatly from country to country. In some places, foreigners can enroll in public schools under certain conditions. And in others, access for them is limited. Or requires meeting additional requirements.
Before enrolling, it's worth checking several things in advance:
And one more thing. The curriculum and requirements may differ greatly from the school the child is used to. So adaptation sometimes takes time.
A public school is a good fit for a child who is ready to actively communicate in a foreign language. Wants to integrate into the local environment faster. And plans to continue their education in that country.
Younger students usually adapt more easily. Teenagers may need more time. Especially when it comes to the upper grades and preparation for final exams.
If it's still difficult for the child to study in a foreign language — you can consider language preparation. Or a different school format. Where international students receive more attention.
When choosing, you shouldn't look only at whether it's public or not. What matters more is the curriculum, the language of instruction, the location, the size of the school, and extracurricular activities. And the opportunities for further education.
