Every school marketing brochure mentions small classes. Every school website has a number. At the International American School of Warsaw, that number is 7:1. If you have spent any time looking at international schools in Warsaw, you may be wondering what this actually means in practice. Here is a straightforward answer.
What Happens in a Class of 18
The maximum class size at IAS Warsaw is 18 students. In practice, many classes are smaller. Think about what that looks like in a typical lesson. A teacher presents a concept. A student does not understand it. In a class of 18, the teacher notices. There is time to stop, rephrase, check in. That same moment in a class of 28 is different. The teacher has more ground to cover, more behavior to manage, and less margin to slow down for one student. This is not a criticism of large-school teachers. It is simple math.
In a class of 18, there is also more room for discussion. Students speak more often. They get more feedback on their work. They are more likely to ask questions because the classroom feels smaller and less intimidating. For children who are still finding their confidence, or who are new to an English-speaking environment, that difference is significant.
What It Means for Shy or Struggling Students
For a child who is shy, moving to a new school is hard enough. Moving to a new country and a new school at the same time is harder. A smaller class does not eliminate that difficulty, but it changes the experience. A teacher who has 12 students in front of them every day knows their names, their history, their habits. They notice when a quiet child has not spoken in two days. They notice when a student who usually does fine on tests is suddenly getting things wrong.
For students who are struggling academically, early identification matters more than almost anything else. Research on learning is consistent on this: the sooner a learning difficulty or a gap in understanding is caught, the easier it is to address. In a small class with a low student-teacher ratio, that identification happens faster. Teachers are not waiting for an end-of-term grade to flag a problem. They see it in real time.
What It Means for Advanced Students
Small classes are sometimes assumed to be mainly for students who need extra support. That is only half the picture. For students who learn quickly and are ready to go deeper, a small class offers something large classes often cannot: time with the teacher. When a student finishes the assigned work and wants to explore the topic further, a teacher with 18 students has time to have that conversation. A teacher with 30 does not, at least not often.
At the International American School of Warsaw, advanced students benefit from this environment consistently. The IB Diploma Programme, for example, requires students to write an Extended Essay and to engage with Theory of Knowledge. Both demand close guidance from a supervisor. That guidance is more meaningful, and more frequent, when the teacher is not stretched across a large group.

How Parents Experience It
If you are a parent at IAS Warsaw, you will find that the communication from the school is more personal than you may be used to. Teachers email parents directly. They reach out when something is going well, not only when there is a problem. Parent-teacher meetings at IAS are actual conversations, not the five-minute slots that larger schools often use. When you call the school, people know your child’s name.
This is not a marketing claim. It is what happens when a school is small enough for everyone to know everyone. For parents who are navigating a relocation and trying to manage family life in a new city, knowing that the school is paying close attention to your child takes one significant worry off the list.

What Boutique Education Means at IAS Warsaw
At the International American School of Warsaw, the 7:1 student-teacher ratio is not a number chosen for a brochure. It reflects a deliberate choice about what kind of school IAS is. A larger school with more students generates more revenue and can build bigger facilities. A boutique school with small classes builds something different: depth of relationship, genuine personalization, and an environment where no student disappears. That is what 7:1 means in practice, and that is what families who choose the International American School of Warsaw are choosing.
