São Paulo, April 2026 — Despite growing interest in language learning, fluency remains a challenge for many Brazilians. Surveys indicate that only 13% of people who say they have some knowledge of English—the most sought-after language in the country—consider themselves truly fluent, even after years of study and participation in lifelong learning courses.

This data reinforces a common perception: formal education is essential for building a foundation and vocabulary, but on its own, it does not always guarantee confidence in using the language in everyday life.

It is in this context that language immersion—especially in exchange programs—is cited by experts as a consistent strategy for putting knowledge into practice. By complementing structured learning, immersion integrates the language into the exchange student’s daily routine and encourages its continuous use in real-life situations, thereby fostering the natural development of fluency.

During an international experience, students need to communicate in order to handle simple, essential tasks, such as asking for information, shopping, getting around the city, and socializing. These everyday situations become constant learning opportunities, as they require comprehension, quick responses, and adaptation to the real-life context of the language.

Studies on second-language acquisition indicate that learning tends to be more effective when the language is used in a functional and contextualized way. Immersive environments are particularly conducive to developing oral fluency and listening comprehension, in addition to helping reduce the fear of making mistakes—a common barrier among students who learn languages only in formal settings and one that is often noticed by families throughout the learning process.

Another important factor is the consistency of exposure. While traditional courses offer limited exposure throughout the week, immersion extends this exposure throughout the day. Active listening becomes part of the routine, with frequent exposure to different accents, grammatical structures, and forms of expression. Over time, sentence construction becomes more natural, reducing the need for constant mental translation.

The process involves mistakes, which are a natural part of learning. By interacting with native speakers and other students in real-life situations, exchange students gradually pick up informal usage, cultural expressions, and nuances of the language, thereby increasing their confidence and communication skills.

According to experts in the field of second-language acquisition, significant progress can be observed as early as the first few weeks of intensive immersion, particularly in terms of comprehension and confidence in communication. Over time, these gains deepen and are reflected not only in fluency but also in the student’s confidence and poise.

For Carla Gama, CEO of Experimento Intercâmbio Cultural—a brand of CVC CORP—the practical use of the language is a key differentiator in the learning process. “Fluency isn’t built solely on grammatical rules, but on the actual use of the language. When students experience the language in their daily lives, they begin to respond and communicate more naturally, which consistently accelerates their learning,” she says.

She points out that, in the Brazilian context, immersion serves as a valuable complement to formal education. “Limited practical exposure, combined with an education that is often more theoretical, can hinder progress toward fluency. International immersion combines structured study with real-world experiences, creating a more well-rounded learning environment, ” she adds.

A point that is often misunderstood when discussing language learning is the relationship between fluency and accent. Speaking a language fluently is not the same as speaking without an accent, and that is natural.

Carla Gama explains that “fluency has to do with being able to communicate naturally, understand, argue, play with words, and make oneself understood with confidence. An accent, on the other hand, is the ‘sonic fingerprint’ we carry from our native language—an almost inevitable trait for anyone who learns another language after childhood. It reveals where we come from, but it doesn’t define how much we know. Striving for fluency is like learning to dance: the important thing is to follow the rhythm with confidence; one’s own style—in this case, the accent—is part of each person’s identity.”
