What is Communicative Language Teaching (CLT)?
The most claimed and least understood approach in ELT, explained properly.
A few years ago, I sat in on a teacher’s lesson, and before class, I remember asking him about his teaching approach. “Oh, I do CLT,” he said, with the confidence of someone telling me he breathed oxygen.
The lesson started. Students opened their books. They did a gap-fill on the second conditional. Then they read sentences aloud in closed pairs. Then they did another gap-fill. Then the class finished.
He looked at me expectantly.
I’ve seen this soooo many times. CLT is the most overused (allegedly) and least understood approach in ELT. Teachers say they do it, coursebooks say they’re built around it, job ads ask for it - but it’s like gold at the end of a rainbow. Ask ten teachers what it actually is, and you’ll get ten different answers (each with various amounts of truth).
I hope that this article will help fix that. Here’s what CLT actually is, what it isn’t, and what it should look like in your classroom.
What Communicative Language Teaching is
First of all, CLT is an approach, not a method.
That distinction does actually matters - methods tell you what to do in a lesson while approaches tell you what to believe about how languages are learned. So CLT doesn’t dictate your lesson structure, it tells you what the lesson is for.
The core idea of CLT is simple: students learn a language by using it for real purposes.
That’s it!
CLT emerged in the 1970s as a reaction against the methods that came before it. Grammar-translation, where students translated literary texts and learned rules in isolation. Audiolingualism, where students drilled sentence patterns until they became “automatic.” Both struggled to efficiently produce students who could actually talk to anyone. CLT was the re-evaluation of the language learning process.
What CLT isn’t
A lot of the confusion around CLT comes from what people think it means but doesn’t.
It isn’t “just chatting.” Free conversation with no goal isn’t CLT. It’s just free conversation.
It isn’t anti-grammar. CLT teachers teach grammar. They just teach it in service of communication, not as the end in itself.
It isn’t a lesson structure. PPP, TBLT, ESA, Test-Teach-Test - all of these can be communicative. Or not. CLT doesn’t replace lesson structures. It sits above them.
And it isn’t optional anymore.
CLT is the dominant approach in mainstream ELT. Almost every coursebook from the major publishers is built on its principles. If you’re teaching English in 2026, you’re probably doing some form of CLT whether you call it that or not.
The core principles
Strip away the academic writing, and CLT is really four principles.
Meaning before form. What students are saying matters more than how they’re saying it, at least at first. You build accuracy on top of meaningful communication, not the other way round.
Authentic language use. Real tasks, real purposes, real materials where you can. If the language wouldn’t be used outside the classroom, ask yourself why you’re using it inside.
Fluency and accuracy both matter, but fluency comes first. Students need to be able to say something before they can say it well. Stopping every error in the moment kills fluency before it can develop.
The learner does the work. If you’re talking more than your students, you’ve drifted away from CLT. The teacher’s job is to set up the conditions for communication, then get out of the way (see my article Whoever Does the Thinking Gets The Language).
What CLT looks like in a lesson
Information gaps. Student A has half the information, Student B has the other half, and they need each other to complete the task. Not a workaround for pair work, an actual reason to speak.
Role-plays with a purpose. Not “act out the dialogue on page 47.” Something like: you’re at a restaurant, you have a dietary restriction, the waiter doesn’t speak your first language, sort it out.
Pair and group work where students need each other’s input. If one student could do the activity alone with a dictionary, it’s not communicative.
Tasks where the outcome matters. The students should care, even a little, whether they get it right. A debate where the winner gets bragging rights beats a discussion with no stakes.
Grammar taught in service of communication. Students need the past simple to tell their weekend story. Teach them what they need to do the thing.
The two versions you should know about
Academics talk about “strong” and “weak” CLT. Here’s what that means:
Strong CLT says learners acquire language by using it. You don’t teach grammar explicitly. You give students tasks, they communicate, and the language develops through use. This is close to Task-Based Language Teaching.
Weak CLT says learners are taught language first, then given opportunities to use it communicatively. This is what most coursebooks do. Present the language, practise it, then a freer activity at the end - close to Presentation, Practice Production (PPP).
Most of us teach somewhere between these two. That’s fine. Pure strong CLT is hard to plan and requires confident, motivated students. Pure weak CLT can slide back into PPP with a role-play tacked on. The middle ground is where most good teaching lives.
Common ways CLT goes wrong
I’ve watched a lot of “communicative” lessons that weren’t. The same problems come up again and again.
Pair work with no information gap. Both students have the same worksheet, so they take turns reading the answers to each other. There’s no reason to communicate, so they don’t.
Role-plays where students recite a script. If the language is fixed in advance, it’s a drill, not a role-play. Real communication requires choices.
“Free practice” that’s actually controlled practice. The teacher says “discuss in pairs” but expects specific target language, then corrects every deviation. The students learn to produce what the teacher wants, not what they mean.
Skipping grammar entirely. Someone told these teachers CLT means no grammar, and they said “hell yes!” with it.
How to test your own lessons
Here’s the question I use, and you can use it too: are my students using English to do something meaningful, or are they just producing English because I asked them to?
If the answer is the second one, the activity isn’t communicative. It doesn’t matter how much speaking is happening. It doesn’t matter how many pair work activities you’ve slotted in. If there’s no real purpose, there’s no real communication.
The fix is usually small - add a gap, a choice, a reason to care about the outcome. Most non-communicative activities can be made communicative with a small tweak.
Final thought
You don’t need to completely rewrite your lesson plans to get to CLT. Just pick one activity from your next lesson. Check it against the four principles and tweak it until it passes.
