A TEFL demo lesson is a short, usually 10 to 20-minute sample class you teach during a job interview so a school can see how you actually run a lesson, not just talk about it. The safest structure is the PPP framework: a quick presentation of the target language, a controlled practice activity, then a freer production task where students use the language on their own. Nail those three stages with good timing and you'll clear almost any demo lesson a school throws at you.
If you've never taught a real class before, the idea of performing a lesson in front of a hiring panel (sometimes with actual students, sometimes with your interviewers pretending to be students) is genuinely nerve-wracking. The good news is that demo lessons reward preparation more than natural talent. Bring a solid plan with clear timings and you'll look far more confident than someone winging it, degree or no degree.
Key Takeaways
- Most TEFL demo lessons run 10 to 20 minutes and follow the PPP structure: presentation, practice, production.
- Interviewers are watching how you manage timing, instructions, and student engagement, not just your grammar knowledge.
- A ready-made 15-minute demo plan (below) covers a full PPP cycle around a simple, universally teachable topic.
- Simple visuals, clear instructions, and checking for understanding matter more than fancy materials.
TEFL demo lesson structure: a ready-made 15-minute plan
Here's the master table. This is a complete, timed demo lesson plan built around teaching simple future plans ("I'm going to..."), a topic that works for almost any level and needs no props beyond a whiteboard or a shared screen.
| Stage | Time | What you do |
|---|---|---|
| Warmer | 2 minutes | Ask students what they did last weekend to activate past tense, then pivot: "What about next weekend?" |
| Presentation | 4 minutes | Introduce "I'm going to + verb" with 3 example sentences and a quick concept check question |
| Controlled practice | 4 minutes | Gap-fill or sentence-building drill using the target structure, checked as a group |
| Freer production | 4 minutes | Pair or small-group activity: students tell a partner three things they're going to do this week |
| Wrap-up | 1 minute | Quick recap question and a genuine, specific compliment to end on a high note |
Why the PPP framework works so well under interview pressure
PPP (Presentation, Practice, Production) is the backbone of TEFL methodology for a reason: it gives you a built-in structure to fall back on when your brain is racing. Presentation is you modeling the language clearly. Practice is students using it in a controlled, low-risk way where mistakes are easy to catch. Production is students using it more freely, which is where interviewers see whether the lesson actually stuck. If you stick to that order and give each stage a fixed amount of time, you'll rarely run into the two most common demo lesson failures: running out of time before production, or having so little structure that the "lesson" turns into a chat.
One of our tutors likes to tell new graduates that a demo lesson isn't really being tested on your English, it's being tested on your ability to run a room. Interviewers are watching whether you give instructions clearly, check that students actually understood before moving on, and adjust on the fly if something isn't landing. A slightly imperfect grammar explanation delivered with calm, clear classroom management will usually beat a technically perfect one delivered nervously and too fast.
Choosing a topic that won't backfire
Pick something universally teachable and low-risk: simple present, going to for future plans, comparatives, basic vocabulary sets like food or daily routines. Avoid anything that assumes specific cultural context, requires students to already know a lot of vocabulary, or depends on props you can't guarantee will be available. If you're told the demo will be with real students, ask their approximate level beforehand. If you're told your interviewers will role-play as students, keep the content simple enough that adults playing along won't feel silly, since that awkwardness tends to derail the pacing more than the lesson content itself.
| Topic | Best for | Watch out for |
|---|---|---|
| Simple present routines | Beginners, young learners | Can feel too basic for adult interviewers role-playing students |
| Going to for future plans | Almost any level, adults or teens | Keep example sentences personally relevant, not generic |
| Comparatives and superlatives | Intermediate learners | Needs a clear visual (photos or objects) to land well |
| Food and ordering vocabulary | Young learners, beginners | Fun but can run long if not tightly timed |
Mistakes that sink an otherwise decent demo lesson
Talking too much is the number one issue. New teachers often explain a grammar point for five straight minutes when ninety seconds would do, which eats into the practice and production time that actually shows off your teaching. Skipping a concept check is a close second: ask a quick question to confirm students understood before moving on, rather than just asking "does that make sense?" and taking silence as a yes.
Overloading the lesson with too much content is another common trap. A demo lesson isn't the moment to prove how much you know, it's the moment to prove you can teach one thing well in a short window. Pick one target structure, teach it cleanly, and resist the urge to add a second grammar point "just in case."
Finally, don't ignore timing. Practice your plan out loud at home with a timer running, not just in your head. Most people are shocked at how much longer instructions take to give out loud than they expect, and running out of time before your production stage is one of the most common reasons a genuinely good demo lesson gets a lukewarm review.
What if you're asked to demo a skill instead of grammar?
Not every demo lesson is grammar-focused. Some schools, especially those hiring for younger learners or conversation-heavy roles, will ask you to demo a vocabulary set, a pronunciation drill, or even a short reading activity instead. The PPP structure still applies, you're just swapping the target language for a target skill: present the vocabulary or sound clearly, practice it in a controlled way (repetition, matching, a simple drill), then let students use it more freely in a short game or conversation task. Don't panic if the topic assigned to you isn't the one you rehearsed most, the underlying structure of a good lesson barely changes.
How to practice before the real thing
Run your plan on a friend, a partner, or even a pet if you have to (talking through a lesson plan out loud is what matters, not who's listening). Time each stage with a phone timer and adjust your plan if a section runs long. If you took your TEFL course through Premier TEFL's courses, you'll already be familiar with PPP-style lesson planning from your coursework, so this is really just applying the same structure under slightly more pressure.
Frequently asked questions
Below are common questions people ask about preparing for a TEFL demo lesson.
A TEFL demo lesson is far less mysterious once you have a structure to lean on. Stick to PPP, pick a simple and universally teachable topic, time your stages out loud beforehand, and focus more on clear instructions and checking understanding than on proving how much grammar you know. If you want more on what schools are actually assessing you against once you're through the interview stage, our guide on what schools really look for in TEFL teachers is a natural next read, and if you're still deciding on interview soft skills more broadly, our post on rocking your online teaching demo class covers that side in more depth.
