You read in English constantly and attend English meetings throughout each day. You listen to English podcasts during your commute. You also write reports, emails, and client communications in English with ease. English fills much of your professional day.
Yet your English does not feel better. In meetings, you still use the same words as two years ago. The gap remains, so you question whether you can move past this limit.
Many advanced non-native professionals share this experience, yet it receives little discussion. The frustration may bring a private thought: something must be wrong with you. Perhaps your effort or ability is the problem. That conclusion is often false. This experience can be a normal part of advanced language development. Your practice method, rather than your effort, may be the issue.
Why progress felt different before
From B1 to B2, progress can be fast and easy to see. New grammar rules become clear, and you learn many useful words. Difficult conversations become possible, so you can measure these gains directly. You now follow texts that were too hard before, while fast speech becomes manageable. This immediate feedback can keep you going.
From C1 to C2, progress looks different, but many learners use old measures. You may learn fewer new grammar rules and improve the grammar you already control. You may also add fewer broad groups of words. Instead, you activate specific words you already know. These gains are smaller, slower, and harder to see. They feel different because the type of progress has changed.
This may limit how well you see progress, not what you can do. As a result, your growth can feel as if it has stopped.

Lyra Practice helps you learn the nuance of high-value workplace expressions, then practice using them in realistic situations.
See how Lyra Practice works →At an intermediate level, the milestones are clear because you can do something new. At an advanced level, you have met most large milestones. What remains is subtle and hard to notice. A word comes too slowly, or a tone feels slightly wrong. You miss a phrase that another skilled speaker might use. These gaps are real and can matter at work, as the research on passive versus active vocabulary shows. Yet standard tests may not capture them because they appear during real work. The right word could shape how people see you. Instead, a safer but less exact word comes out.
You may still improve, but your usual tools may not show it. There is a real gap between "can hold a professional conversation in English" and "can quickly find the right word in many situations." This gap differs from the one between B1 and B2.
Why passive immersion stops working
At an intermediate level, passive exposure can work well. It includes reading, listening, and simply being around English. This exposure can produce visible gains because much grammar and vocabulary is unfamiliar. Each new item may teach you something useful.
At an advanced level, you already know a great deal. Some known words may not come quickly under pressure at work. Passive exposure can still add words, but may not activate known ones alone. What actually builds active recall includes using each word in context. Seeing or hearing the word is often not enough. More immersion may bring smaller gains at this stage. Your goal has shifted from finding words to using known words. That shift calls for more active practice.
This is why the plateau can feel so stubborn. Your effort, time, purpose, and immersion are all real. But that effort may not fit the problem you have left.
What progress actually looks like at this level
Advanced progress may not look like new skills; instead, specific words become easier to use.
You reach for "mitigate" in a meeting, and it comes quickly. You do not pause to ask whether it fits. You write an email that sounds like you: exact, confident, and intentional. It is not a flat version of your voice. Word by word, your speech gets closer to your thinking.
Each moment is small, but these moments gradually add up over time. Your language can then match your thinking more precisely. As the evidence on how long activation takes shows, deliberate practice can support this change. Use each word intentionally in realistic situations, then track it and get feedback.
At this level, track the words that become automatic in professional situations. Do not focus only on new skills; measure and practice progress differently.
What the plateau actually is
Not seeing progress does not prove that you hit a ceiling. Your old method may no longer fit the problem. Passive immersion helped when you needed many new words. It may help less when you need to activate known words. Therefore, the plateau may be in your method, not your ability.
The remaining gap is specific: you know some words but cannot use them under pressure. This is a practical problem, not a deep flaw. You can work to close the gap with different tools and practice.
