After the Diploma, How Do You Keep a Language?

What research on language attrition, memory and spaced practice tells us about staying fluent after an exam.

You pass your C1 exam. After months of speaking practice, writing assignments and mock tests, the certificate arrives. You put it somewhere safe. A year later, a colleague asks you a question in that language. You understand it immediately. You know what you want to say. And yet, the answer takes longer to put together than you remember.

Has your level changed? Or have you simply had fewer chances to use what you know?

Think about someone who has trained for years at the gym. After a long break, they still remember how to perform a lift, but the weight they used to handle comfortably may feel different. Returning to a language can feel similar. A diploma records what you demonstrated on exam day. The way you use the language afterwards helps shape how readily you can draw on it.

What do we keep after we stop studying?

In 1984, psychologist Harry Bahrick tested 587 people who had studied Spanish at school or university between one and 50 years earlier. He examined reading, grammar and vocabulary, including whether people could recognise words and recall them. A substantial amount of knowledge remained accessible years later, and the level of initial training helped predict how much people retained. The study found no statistically significant effect of participants’ reported practice on the skills it measured. Spontaneous conversation would put those skills to a different test.

Imagine seeing a word in a French article and knowing immediately what it means. Now imagine trying to find that same word while explaining your opinion to someone. In the article, the word is already there and the sentence gives you clues. In conversation, you have to find it yourself and fit it into an answer while the exchange moves on.

That difference is easy to miss when most of your contact with a language comes from podcasts, books or films. Those are valuable ways to stay in touch with a language. Conversation gives you a chance to formulate an answer, handle an unexpected follow-up and rephrase when the exact word escapes you.

What happens to advanced speakers after classes end?

Nicole Tracy-Ventura and colleagues followed 28 advanced second-language users over eight years, including six years after formal instruction ended. Participants completed speaking assessments, interviews and vocabulary tests at several points. Continued exposure was linked to long-term retention and some further development of oral proficiency and fluency. The level participants had reached by the end of instruction also mattered for some aspects of performance. Even participants with limited exposure showed little decline in this small study.

In a separate study, researchers recorded 114 multilingual students shortly before they left secondary school and again about 16 months later. They examined fluency and vocabulary variety in English and in either French or Italian. Post-school use had a clearer relationship with changes in French or Italian, where the students’ starting proficiency was lower. The relationship was weaker in English, where they had started at a higher level. Some participants also felt they had lost more speaking ability than their recordings showed.

If you’ve ever come away from a conversation thinking, I used to speak much better than that, one exchange can give you something more specific to work on. Perhaps you struggled to find a particular expression or realized you’d rarely discussed that topic in the language. Your foundation can still be there, and the difficulty you noticed gives you somewhere to start.

Why make room for one conversation a week?

Su Kyung Kim and Stuart Webb analyzed 48 second-language experiments involving 3,411 participants. On average, learners benefited from spreading practice across sessions. Longer gaps between sessions tended to help more on delayed tests, though the results varied with the material, the activity and other factors. The research supports returning to what you practise over time. The ideal frequency for maintaining advanced conversation skills remains an open question.

At Glossart Languages, if you rarely speak the language in daily life, I suggest starting with one real conversation a week. A lesson, a language exchange or a regular call with a friend can give you a place to use what you worked so hard to learn. If you already speak the language regularly with family, friends or colleagues, those conversations count too.

What does maintenance look like at an advanced level?

Imagine discussing a decision you made at work. You can explain your reasoning clearly, but when someone challenges it, your answer sounds more abrupt than you intended. In a lesson, you can pause and try a different response.

I see why you’d be concerned. My main reason for choosing this approach was…

Then you go back into the discussion and see how the new wording feels in context.

The following week, you might discuss a book, a news story or a decision in your own life. If a similar moment comes up, can you acknowledge the other person’s point and explain where you differ? The language is familiar. The situation is new. That gives you a way to see whether the expression is becoming easier to use.

If class is your only speaking opportunity that week, you can do the whole exercise in the lesson. Talk about something that matters to you, notice one moment you’d like to handle differently and try it again. Over time, you can look for changes that matter in your life. Perhaps you can tell a story without losing the thread, explain a technical idea to someone outside your field or get through a meeting without rehearsing every sentence in advance.

What do you want to be able to do a year after your exam?

A diploma is worth celebrating. It can also be a good moment to ask where the language fits into your life now. Maybe you learned Italian to speak with family, English to participate in international meetings or French because you love the books you can read in it. The answer gives you a reason to make room for the language once the exam is over.

If you had one conversation a week in a language you already speak well, what would you want to talk about?
