🤚 Raise your hand if you are teaching Intermediate learners where everything seems “fine”, but nothing is improving. New TEFL teachers, this one is also for you.
Enter the “Intermediate plateau”.
What is the Intermediate plateau?
The Intermediate plateau in language learning is a state of limbo when Intermediate-level language students experience a lull in their learning despite their best efforts.
The speed in which they were able to make visible progress has slowed down, and frustration sets in. For us TEFL teachers, we feel our students’ pain and start questioning our own abilities!
The good news is that plateauing is normal, even good! It shows that your students have achieved comfort with the language components they have learnt. It is a phase of consolidation, not failure.
That being said, understanding why the Intermediate plateau happens makes it far easier to help students move past it.
Causes of the Intermediate plateau: Why Intermediate ESL students stop progressing
There are a few reasons why students plateau at an Intermediate level. Bear in mind that it’s a natural part of language acquisition. It only becomes problematic when students don’t move out of this phase.
Let’s take a look at why students get stuck in the Intermediate plateau.
Staying in the comfort zone
Once students have reached the B1 Intermediate-level, they tend to rely on using the grammar structures and vocabulary that feel comfortable to them. They get stuck by reusing the same phrases, sentence structures, and expressions.
This is not necessarily problematic when it comes to speaking a language, because Intermediate level is enough to get by in a basic conversation. But it limits growth. If students don’t intentionally push themselves to get out of this plateau, progress naturally slows down.

Limited speaking and immersive practice
At the Beginner A1 level, simply being in a classroom setting leads to visible progress. At the Intermediate level, classroom exposure is not enough.
What usually happens is that Intermediate-level students leave English in the classroom, and go back to speaking in their native tongue everywhere else. In most cases, they don’t have anyone to practice their English with in their daily lives, besides their teacher.
Not getting organic exposure or a chance to converse in English outside the classroom robs them of developing their confidence, fluency, and opportunities for more learning.
Fewer “easy wins”
“Easy wins” like simple grammar structures, basic vocabulary, and common expressions, are many and frequent at the Beginner level. However, as language gets more complex and nuanced at the Intermediate level, progress is a bit slower and more subtle. Progress is still happening, even if your students don’t feel it.
Fossilised errors
Students find themselves carrying over the mistakes they learnt in the early stages of their learning into the B1 stage. These errors are often the result of first language transference or overgeneralisation.
Despite repeated corrections, they continue to make the same mistakes over and over again.

Can you guess what one of the most common fossilised errors is? It’s … pronunciation. In English, there are certain sounds that don’t exist in other languages, like the sound “r” in Japanese, Mandarin, and Korean, or the sound “th” in Spanish.
I vividly remember trying to teach my South Korean Co-teacher how to say “railway”. The mouth action that was going on was both hilarious and frustrating for her. She struggled so much to sound out the “r” and “l” together. It definitely was a learning moment for both of us – to teach and be taught.
Breaking through fossilized errors is one of the hardest parts of being an Intermediate-level student. It’s one of the biggest causes of frustration in students and teachers alike. Breaking the habit is hard!
Signs your students are at a plateau
Plateauing is quite insidious. It’s easy to miss the signs as a teacher. Here are some common signs of plateauing that you should look out for in your Intermediate students:
- Slow progress despite regular lessons and studying.
- Understanding English well, but trouble articulating their thoughts clearly.
- Making the same mistakes over and over again.
- Vocabulary remains limited even after new words have been taught.
- Frustration sets in, and motivation and confidence drop.
It’s fair to say that we have all been there at one time or another. We try our darndest to learn something new, but it just won’t stick.
Similarly, your students start off feeling frustrated, then their confidence whittles away. They may not be as engaging as they were before and may be more subdued. Next, motivation dwindles, and students just stop trying.
This emotional shift is a glaring warning sign to look out for.
How teachers can address the Intermediate plateau
For some teachers, the go-to strategy to attempt defeating plateauing is to rinse and repeat what they have been doing all along. Which just doesn’t work. In fact, it worsens the issue.
At the Intermediate stage, both student and teacher need to change how they engage with English. As they say, “Be the change you want to see in the world.”
What doesn’t work
Doing more of the same
Continuing with the same lesson formats and activities will keep your students in stagnation-mode. To get a different result, the formula needs to change.
Over-focusing on accuracy
Overly focusing on correction to ensure accuracy doesn’t work. It not only makes your students feel self-conscious about how much they are doing wrong, but also makes them hesitant to engage, which limits fluency.
Overloading students with new content
Adding new content into the mix, like new grammar and vocabulary, is like increasing your reps when your muscles haven’t recovered yet. If there are gaps in knowledge, moving on to more complex concepts will overwhelm students.
What does work
Switching things up
Change lesson formats and activities. Focus more on fluency than accuracy with activities like discussions, problem-solving, and role-plays. Get students excited again with opportunities to speak without the pressure of needing to be 100% accurate.

Focus on expression
Instead of teaching or re-teaching single-word vocabulary items, teach chunks. That is, combining words together. For example, instead of just teaching “appreciate”, teach the chunk “I’d appreciate it if …”.
Additionally, throw more collocations into the mix and functional language. Get your students expressing themselves with useful expressions that will help them outside the classroom.
Increase exposure to authentic English
Get students to interact with authentic English content and people. Podcasts, videos, articles, music, and language exchange apps work like a charm!

Encourage reading
I cannot stress enough the power of how reading can transform one’s English-speaking abilities.
Recommend B1 level books and set small reading goals to make learning goal-driven, too. Organic exposure to language components from reading reinforces learning. Plus, reading is awesome.

Small goals and track progress
As progress appears to slow down during the Intermediate phase, set smaller and achievable goals. Remind students of these and their progress, often. Seeing any progress really boosts one’s confidence.
My parting words to you are that you should always remember that the Intermediate plateau is normal. By no means is it easy, but it is manageable with the right strategies.
Keep in mind that students have and will progress past this phase; it just takes some time and effort on both sides.
As a TEFL teacher, developing your teaching skillset through continuous personal development (like a TEFL Top-Up Course) will sharpen your skills and better equip you to not only recognise plateaus early on, but to meet them head-on with tried and tested strategies that lead to your students’ success.
