There’s something uniquely nerve-wracking about being asked to “teach a class” before you’ve even landed the job. Whether it’s in front of real students, a couple of staff members, or just a webcam, the TEFL demo lesson is your moment to turn a piece of paper—your CV—into something real. Schools want to see how you carry yourself, how you explain things, how you connect. And more than anything, they want to know if you'd be a good fit for their classroom.
For many new teachers, this part of the process is more intimidating than the actual job. But here’s the secret: schools aren’t expecting perfection. They’re looking for someone who is prepared, clear, engaging, and in control of their time and space. Someone who knows how to speak simply without sounding robotic, and who shows up with genuine energy—whether in person or online.
Even experienced teachers feel the pressure. That’s normal. The key is preparation—not just knowing your lesson plan, but understanding what the school is watching for and why they care. Once you shift your mindset from “performing” to “connecting,” the demo lesson becomes far less intimidating—and a whole lot more fun.
A demo lesson isn’t about showing off how much grammar terminology you know or how many games you can cram into 20 minutes. It’s a test of your classroom presence. Think of it as an audition, not an exam. The school is trying to answer one core question: Would we feel confident putting this person in front of our students?
It’s not about reciting rules or theory. Most schools assume you already have your TEFL certificate. What they don’t know is how you apply that knowledge in real time. Can you:
These are the things that really matter in the classroom—and they’re exactly what demo lessons reveal.
Here’s what schools usually evaluate:
In most cases, you won’t be teaching an actual class. Instead, your “students” might be:
Either way, assume your observers know exactly what they’re looking for—and they’re more interested in your attitude and clarity than in fancy tricks. Your job is to show them you’re someone students can learn from and feel comfortable around.
Before you even start planning your demo, make sure you have all the information you need. The more details you gather upfront, the easier it is to deliver a demo that feels natural, age-appropriate, and level-appropriate. A well-planned 10-minute lesson is far more impressive than a generic one that misses the mark.
Don’t be afraid to ask questions. Schools want you to be prepared—and thoughtful questions show that you care about doing the job well. Here’s what you should find out:
Student level: Are they complete beginners (A1), false beginners (A2), pre-intermediate (B1), or beyond? Knowing this helps you grade your language and choose appropriate vocabulary and grammar.
Age group: Teaching 6-year-olds and teaching adults are two completely different experiences. You need to know if your activities should involve songs and gestures—or conversation prompts and real-life scenarios.
Class size: Will your demo be assessed as if you’re teaching one student or a full class? This affects your interaction style and group activity planning.
Time limit: Some demos are just 5–10 minutes. Others might be up to 30. Either way, it’s not enough time to “teach everything,” so plan for depth, not breadth.
Grammar/vocab focus vs. free choice: Some schools assign a topic. Others want to see what you choose and how you teach it. If they don’t give you a topic, make sure to pick one that fits the age and level well (see next section).
In-person or online: Are you expected to be on Zoom with a webcam, or standing in front of a classroom? This changes everything—from your materials to your tone to your tech setup.
These details affect your entire approach:
The clearer the brief, the more confident you’ll feel. And the more tailored your lesson is to the imagined students, the more likely it is to impress your observers.
If you’re given free rein over what to teach, don’t overthink it. The goal isn’t to impress with complexity—it’s to show that you can teach something clearly, effectively, and with confidence. The best demo lessons are simple, focused, and student-centered.
Here are some tried-and-tested demo lesson themes that work well across a variety of age groups and settings:
Greetings and Introductions
Great for young learners or true beginners. Simple phrases like “What’s your name?” and “Nice to meet you” give you lots of room for interaction, repetition, and roleplay.
Daily Routines or Telling the Time
These lessons work well for pre-intermediate students and are easy to make visual with flashcards or drawings. They also lead naturally into pair work or surveys.
Likes/Dislikes or Food Vocabulary
Perfect for teenagers and kids. It’s engaging, easy to personalize, and gives you a chance to use realia (menus, pictures, etc.) or introduce simple grammar like “I like…” vs. “I don’t like…”
There Is/There Are & Prepositions of Place
A fantastic choice for interactive whiteboard demos or physical classroom settings. Use simple room layouts or classroom objects to get students describing what they see.
Pick a topic that allows for active student participation. You want your observers to see students speaking, moving, or reacting—not just nodding while you talk. That interaction is where the real “teaching” shines through.
A strong demo lesson starts with a solid plan—but don’t make the mistake of overcomplicating it. Simplicity, structure, and clarity are what matter most. Even if your lesson is only 10 minutes long, your plan should show that you understand how lessons flow and how students learn.
Stick to the basic four-stage model:
You don’t need to squeeze all four in if your time is limited. But your plan should show where you're going and why—even if it's just a focused "presentation + practice" mini-lesson.
One of the biggest rookie mistakes in demo lessons is trying to teach too much. Focus on one target structure (e.g., “I like ___”), one function (e.g., ordering food), or one short vocabulary set (e.g., animals, school subjects, or time phrases).
Your objectives should be realistic for the time limit and the level. For example:
Objective: Students will be able to ask and answer simple questions about favorite foods using "Do you like...?" and "Yes, I do / No, I don’t."
If you can achieve that goal in 10–15 minutes and show student interaction along the way, you’ve done your job.
Your plan should be clear enough that someone could teach it just by reading it. Include:
If you're submitting a written plan, keep the formatting clean and easy to follow. Bullet points work better than long paragraphs. Avoid jargon. Show that you’ve thought it through—but don’t make it overly academic.
You’re not there to prove how much you know—you’re there to show how clearly you can teach. Pick one simple point and teach it well. Let your confidence and clarity come through in your planning, not just your delivery.
No matter how experienced you are, the first time you deliver a new lesson shouldn’t be when you're in front of a camera or an observer. Practicing your demo lesson out loud—even if it feels silly—is one of the best ways to work out the kinks and build confidence.
Don’t guesstimate. Use a stopwatch and actually go through the entire lesson. You might be surprised by how fast 10 minutes goes—or how long it takes to give clear instructions.
Timing also helps you:
Teaching isn’t just talking—it’s movement, gestures, facial expressions, tone. Stand up while you practice. Use the space around you. Pretend there are real students in front of you and walk through the steps as if you're there.
Even if you’re teaching online, you’ll project more confidence and warmth when you feel like you're in teacher mode.
This is one of the most powerful prep tools available—and most teachers skip it.
Recording your rehearsal helps you:
Even watching it once can lead to big improvements.
If you’re nervous about speaking to a screen, get a family member, friend, or fellow teacher to sit in as your “student.” If that’s not possible, rehearse in front of a mirror or your webcam. Say the instructions aloud. Wait for imaginary student responses. Walk through the transitions.
It might feel silly—but it’s better to feel silly now than awkward during your demo.
If your lesson involves flashcards, realia (menus, food items, toys), or a whiteboard—have them ready and tested. For online lessons:
The smoother your materials are integrated, the more confident and professional you’ll appear.
If your demo lesson is online, your "classroom" is now your webcam—and everything from your lighting to your energy level plays a bigger role than you might think. Teaching through a screen means you need to work a little harder to build presence and connection, but with the right setup, you can absolutely shine.
Make sure your head and shoulders are clearly visible, with enough space for natural gestures. You don’t need a fancy setup, but your background should be clean and uncluttered—avoid messy beds, distracting posters, or kitchen chaos. A plain wall, bookshelf, or teaching corner is ideal.
If you’re teaching kids, consider adding a small, age-appropriate visual behind you (alphabet letters, a small world map, etc.), but keep it tidy. You want to look prepared, not chaotic.
You don’t need studio lighting—but you do need to be well-lit and clearly heard.
Poor lighting and muffled sound are easy ways to lose engagement—even if your lesson is great.
Test your:
Have a backup plan in case your main device crashes. Keep a second device handy if possible, and have your lesson plan saved both locally and in the cloud.
Don’t just talk—show. The best online demo lessons make use of:
But don’t overdo it. Keep visuals clean and purposeful—less is more when students only have a few seconds to take it in.
Online lessons need more voice modulation, facial expression, and gesture than in-person teaching. Your screen shrinks your presence, so make it count:
Even if you're nervous, a friendly tone and well-paced delivery make a big difference.
When it’s finally time to teach your demo, take a breath. You’ve prepped. You’ve practiced. Now it’s about showing up and doing what you’ve trained to do—teach in a way that feels calm, confident, and connected.
Whether you’re walking into a classroom or joining a video call, arrive 10–15 minutes early. Check your tech one last time. Have your lesson plan, materials, and backup ready to go. Take a moment to center yourself—you’re not just trying to impress; you’re here to teach.
Dress professionally, even if it’s online. Clean, smart attire (at least from the waist up!) helps you feel more focused and sends the right message to your observers.
Greet your observers and any students with a confident smile. If it’s a mock class, treat the observers like students and set the tone early. Make eye contact (with the camera, if online), speak clearly, and give the impression that you’re fully in control—even if your heart’s racing.
Slow down, especially if your demo is for beginner-level students. Use short, clear instructions, demonstrate as you go, and pause often to check understanding.
Avoid teacher talk. Instead of “I’d now like you to open your books and find page 12 where we’ll begin a short warm-up,” say: “Open your book. Page 12. Let’s start the warm-up together.”
Clarity beats cleverness every time.
If you’re given a class list or student names, use them. If not, invent names or just say “you” and use gestures. Either way, get students talking within the first few minutes—even if it’s just repeating after you or answering yes/no questions.
A demo isn’t a lecture. The sooner students are interacting, the better your lesson will flow.
It’s not enough to explain. You need to check that your “students” understand. Use:
This shows you're not just delivering content—you’re monitoring learning, too.
Sometimes your activity finishes early. Sometimes a student doesn’t respond. Sometimes tech glitches throw off your timing. That’s fine.
What matters is how you handle it.
Have a short backup activity ready (a game, a quick pair share, or a review question). Staying calm and transitioning smoothly—even when things shift—is often the most impressive thing you can do.
It’s easy to focus so much on impressing the observers that you forget who the lesson is actually for—the learners. Whether your “students” are real people or imaginary participants in a mock setup, your demo should feel like a real class, not a scripted performance. Schools want to see that you know how to connect, involve, and respond—not just deliver.
You’re being observed, yes—but don’t fall into the trap of over-performing. A calm, student-centered teacher who interacts naturally will almost always stand out more than someone who is overly animated or rehearsed.
Ask yourself: Are you talking to your learners—or just at them? Are they doing anything, or are they just watching you go through your slides?
A lot of teachers fall back on “What’s this?” or “What’s the answer?” Those are fine for brief checks, but they don’t give insight into how well students actually understand or apply the language.
Instead, aim for meaningful interaction:
Even with beginners, small open-ended tasks show you're building communication, not just testing memorization.
It’s your lesson—but it’s their class. Observers want to see that you know how to step back and let students take the spotlight.
Use techniques that increase student talk time (STT):
As a rule of thumb: If you’re talking for more than 60–70% of the demo, that’s probably too much.
Mistakes are part of learning, and schools want to see how you handle them. Don’t freeze up—or overcorrect. Instead:
Positive energy goes a long way. A simple “Nice try,” “Great sentence,” or “Well done, everyone!” can boost student confidence and make your class feel more welcoming.
You want your observers to see that students would enjoy learning with you—not just survive it.
Once your demo’s over, don’t be surprised if the interview continues. Many schools will ask questions about your lesson plan, your decisions, and how you’d adapt the lesson in real-life situations. This isn’t a trick—it’s a chance to show your ability to reflect, adapt, and think like a teacher.
“Why did you choose this topic?”
They want to hear that your choice matched the student level, allowed for interaction, and had a clear objective. Be specific.
“How would you extend the lesson if you had more time?”
Show that you can build on what you taught—e.g., move from controlled practice to a freer activity, or assign a follow-up task.
“What would you change for a stronger or weaker group?”
Talk about adjusting pace, simplifying instructions, or increasing the challenge through more complex language or less scaffolding.
“How did you know if students were learning?”
Mention concept checking, student output, error correction, or engagement during tasks.
If something didn’t go perfectly (and it probably won’t), it’s okay to acknowledge it—but don’t turn it into a confessional. Instead of saying, “I messed up the timing,” try:
“I noticed I ran a bit short on time. Next time, I’d add a short review or follow-up task to keep the flow going.”
That shows self-awareness, not insecurity.
This part of the process is about showing that you’re thoughtful, adaptable, and genuinely care about your students’ experience. Even if your lesson was strong, how you reflect on it can be what seals the deal.
Even great teachers can stumble during a demo lesson—not because they aren’t capable, but because nerves, over-preparation, or poor guidance get in the way. Here’s a quick list of common pitfalls to watch out for, so you can avoid them and focus on what really matters.
You’ve only got 10, maybe 20 minutes. Trying to cram in multiple grammar points, a long vocab list, or several activities is a recipe for stress and confusion. Keep it simple. One clear objective is more powerful—and more memorable—than a cluttered lesson that feels rushed.
This one’s tempting. You’re nervous, you want to show you know your stuff, and suddenly... it becomes a monologue. But a good demo lesson isn’t about your performance—it’s about creating space for students to speak, practice, and engage. If you’re speaking for more than two-thirds of the time, try cutting back.
A brilliant activity can fall flat if students don’t understand how to do it. Avoid long-winded instructions. Break them into small, clear steps. Demonstrate what you want them to do. And always check they’ve understood before starting the task.
Example: Instead of “You’re going to form groups and ask each other questions using the past simple tense about your weekend activities,” try:
“Ask your partner: ‘What did you do on Saturday?’ Then answer. Go!”
It’s easy to assume students understand—especially if they’re quiet and nodding. But silence isn’t comprehension. Use CCQs (concept-checking questions), examples, or mini-practice to confirm they’ve got the target language before moving on.
“Can I say, ‘He go to school yesterday’?”
“No? Right—what’s the correct sentence?”
This shows you’re monitoring learning, not just delivering content.
Yes, it’s a demo. But schools aren’t looking for a show—they’re looking for a teacher. Don’t get lost in buzzwords, fancy tech, or over-scripted delivery. Smile. Teach clearly. Get your “students” involved. That’s what wins people over.
Running out of time—or finishing way too early—can throw off your whole lesson. This often happens when teachers forget to practice with a timer. Plan a flexible final task you can shorten or extend, and always have a small backup activity in your pocket, just in case.
A TEFL demo lesson isn’t a test of perfection—it’s a chance to show how you teach, how you think, and how you connect. You don’t need to blow anyone away with theatrics or complex content. What employers are really looking for is clarity, confidence, and a calm, student-centered approach.
They’re hiring you, not your PowerPoint.
So take a breath. Prepare well. Practice with intention. And walk into that lesson—whether online or in-person—with the mindset that you’re here to help students learn, even in a 10-minute window.
The demo might seem like a hurdle, but it can also be a highlight—a moment where everything clicks and your new teaching journey begins.
