Of all the items in an ESL teaching portfolio, the demo lesson is the one recruiters scrutinize most closely. A strong demo lesson proves you can plan, instruct, manage a classroom, and adapt on the fly — all in a single, observable artifact. Whether you’re submitting a recorded demo video, teaching a live sample lesson during an interview, or simply showcasing a written lesson plan in your portfolio, this guide walks you through exactly how to design, deliver, and present a demo lesson that wins jobs.
What Is a Demo Lesson?
A demo lesson is a sample lesson you teach (or present as a written plan) to demonstrate your teaching ability to an employer. It typically takes one of three forms:
- Written demo lesson plan included in your portfolio — the focus of this guide.
- Live demo lesson taught to real students or interviewers during the hiring process.
- Recorded demo video submitted in advance, common for online teaching platforms.
All three draw on the same underlying skill: the ability to design a coherent, engaging, well-paced lesson with clear objectives and visible student learning.
Why Demo Lessons Matter So Much
Resumes can be padded. References can be flattering. But a demo lesson is hard to fake — it shows your actual teaching in action, or at minimum your actual thinking as a planner. For ESL roles specifically, recruiters use demo lessons to evaluate:
- Lesson structure and pacing
- Clarity of instructions and concept-checking
- Student-centeredness vs. teacher talk time
- Materials design and use of resources
- Classroom management instincts
- Adaptability and responsiveness
For senior roles, the demo lesson may be the single most weighted component of the entire application.
Recruiters can forgive a thin resume. They rarely forgive a weak demo lesson.
Anatomy of a Strong Demo Lesson Plan
Whether it lives in your portfolio or forms the basis of a live demo, a strong lesson plan follows a predictable structure. The framework below is widely accepted across TEFL, CELTA, and Trinity training, and it’s the structure recruiters expect to see.
The Standard Lesson Shape
- Lead-in / warm-up — engages students, activates prior knowledge, sets the topic.
- Context and presentation — introduces the target language or skill in a meaningful context.
- Controlled practice — students practice the new language in a structured, supported way.
- Freer practice / production — students use the language more independently in a communicative task.
- Review and closure — summarizes learning, addresses errors, sets up next steps.
Missing any of these stages is a red flag for recruiters trained in communicative methodology.
Required Header Information
Every demo lesson plan should open with a clear header that lets the recruiter understand the context at a glance:
- Lesson topic and target language
- CEFR level (A1, A2, B1, B2, C1)
- Student age group
- Class size
- Lesson duration
- Assumed prior knowledge
- Main aim and subsidiary aims
- Materials needed
Choosing the Right Lesson to Demo
Not every lesson makes a good demo. When selecting a lesson for your portfolio or interview, prioritize:
- A clear, single language focus — one grammar point, one vocabulary set, or one functional language area. Avoid “skills soup” lessons.
- A level you’re genuinely comfortable teaching. Don’t demo a C1 lesson if your strength is A2.
- A communicative aim that culminates in students producing language, not just drilling it.
- A context that’s engaging — a story, a problem, a real-life situation students can relate to.
- A lesson that showcases your strengths — if you’re great with materials, pick a lesson where your handouts shine.
Strong demo lesson topics include: present perfect for experiences, conditionals for hypothetical situations, functional language for giving advice, vocabulary for describing people, or a reading lesson on an engaging topic.

Writing the Lesson Plan: Stage by Stage
Here’s how to write each stage so that it both teaches well and reads well to a recruiter.
Stage 1: Lead-In (3–5 minutes)
Hook the students and activate prior knowledge. Use a picture, a short anecdote, a question, or a quick personalization task. The aim is engagement, not teaching yet.
Example: Show three pictures of people doing extreme sports. Ask students: “Have you ever tried any of these? Would you like to?” This sets up a present-perfect lesson without pre-teaching anything.
Stage 2: Context and Presentation (8–12 minutes)
Introduce the target language in a meaningful context — ideally through a listening or reading text where the language appears naturally. Elicit or present the form, meaning, and pronunciation of the target language. Use concept-checking questions (CCQs) rather than “do you understand?”
Example CCQs for present perfect: “Are we talking about a specific time in the past? No. Is the experience important now? Yes.”
Stage 3: Controlled Practice (5–8 minutes)
Students practice the new language in a structured way — a gap-fill, a matching exercise, a transformation drill. The focus is accuracy. Provide clear answers and immediate feedback.
Stage 4: Freer Practice / Production (8–12 minutes)
Students use the language in a communicative task — a role-play, a discussion, an interview, a problem-solving activity. The focus is fluency. Monitor but don’t interrupt; note errors for delayed feedback.
Stage 5: Review and Closure (3–5 minutes)
Summarize the lesson, address two or three common errors from the production stage (anonymously), and set a brief homework task that reinforces the aim.
The Power of Annotations
The single highest-leverage addition to a portfolio demo lesson plan is the annotation. For each stage, include short margin notes explaining why you made each choice. Annotations turn a static plan into a window into your thinking and dramatically increase the plan’s value to recruiters.
Example Annotation
Next to the lead-in stage: “I chose pictures over a text lead-in because visual hooks work especially well with this age group, and the question ‘would you like to?’ primes the modal language we’ll encounter later.”
Recruiters consistently rate annotated plans higher than unannotated ones, because annotations demonstrate reflective practice — a core marker of a strong teacher.
Demo Lesson Plan Evaluation Rubric
Use this rubric to self-assess your plan before adding it to your portfolio or teaching it live.
| Criterion | What Strong Looks Like |
|---|---|
| Clarity of aim | One main aim, stated as student ability (“students will be able to…”) |
| Logical staging | Clear progression from presentation to controlled to freer practice |
| Context | Target language emerges from a meaningful, engaging context |
| Concept checking | Specific CCQs that verify meaning, not “do you understand?” |
| Student-centeredness | Majority of lesson time is student production, not teacher talk |
| Materials | Original, well-designed, and supportive of the aim |
| Pacing | Realistic time allocations that sum to the lesson length |
| Anticipated problems | Foresees likely difficulties and notes solutions |
| Differentiation | Accounts for mixed ability within the class |
| Assessment | Includes a way to check learning has happened |
Live Demo Lessons: Practical Tips
If your demo is taught live — whether to real students or to interviewers role-playing as students — the plan is only half the battle. Execution matters just as much.
- Arrive early and test the tech. Projector, speakers, slides — confirm everything works.
- Bring backups of everything. Print materials in case tech fails.
- Keep your instructions short and check them. “You have three minutes. Compare your answers with your partner. Go.”
- Monitor actively during practice. Move around; don’t sit at the front.
- Smile and build rapport quickly. Especially with students you’ve never met.
- Stick roughly to your timing. Running significantly over signals weak planning.
- Be ready to adapt. If students struggle, slow down; if they excel, push further.
Recorded Demo Videos: Practical Tips
For online teaching platforms, a recorded demo video is often required. Treat it as a real lesson with high production quality.
- Use good lighting and audio. A cheap ring light and USB microphone transform the result.
- Teach to an imaginary class or recruit a friend to play a student.
- Show energy and clear pronunciation. Platforms evaluate presence as much as pedagogy.
- Use visible slides or props to demonstrate your materials skills.
- Keep it short — 3 to 5 minutes unless the platform specifies longer.
- Include a clear opening, a mini presentation, and a short practice stage. Don’t try to cram a full lesson in.
- Edit lightly. Cut dead air, but don’t overproduce — authenticity matters.
Common Demo Lesson Mistakes
- No clear aim. A lesson without a stated aim looks unstructured.
- Too much teacher talk. Recruiters watch the ratio of teacher-to-student talk time.
- Skipping concept checking. “Do you understand?” is not a check.
- Overloading the lesson. Trying to teach three grammar points in one lesson.
- Ignoring timing. Stages with no time allocations look vague.
- No anticipated problems. Strong plans acknowledge what could go wrong.
- Generic materials copied from a textbook — show original design.
- Forgetting the freer practice stage. Skipping production is a major red flag.
