When I completed the CELTA, I felt like I had unlocked a whole new level of teaching. I had techniques, structure, feedback—and most importantly, confidence.
Now, as I work through Delta Module 2, I’m realizing something bigger: CELTA gave me the skills to teach; Delta is giving me the mindset to grow.
Although both are Cambridge qualifications, CELTA and Delta Module 2 are entirely different animals. And in this post, I want to unpack those differences—based on my own journey as someone who’s been through CELTA and is currently experiencing the deep dive of Delta.
1. CELTA Says “Teach Like This.” Delta Asks, “But Why?”
The CELTA approach is highly practical. You’re given effective methods and structured lesson models. It’s a fast-paced program designed to get you classroom-ready, fast.
Delta Module 2, on the other hand, demands that you pause and reflect. It’s about justifying your choices, linking them to theory, learner needs, and context.
🔹 CELTA: “Use task-based speaking activities.”
🔹 Delta: “Why this task? Why now? What would you do if it failed?”
It’s not just about delivery anymore. It’s about professional judgment.
2. The Rhythm: Fast Execution vs. Deep Reflection
CELTA is famously intense. Input sessions in the morning. Lesson planning in the afternoon. Teaching and feedback in the evening. Every day is action-packed.
Delta’s pressure feels different. It’s not a sprint; it’s a mental marathon. Writing 2,500-word background essays, revising lesson frameworks, analyzing student output—it’s a more academic, introspective process.
3. The Feedback Hits Harder—In a Good Way
CELTA feedback is developmental. Tutors guide you with specific comments on what worked and what didn’t.
Delta feedback is often layered and analytical. It requires you to look at your lesson through a theoretical lens. The tutor doesn’t just tell you what to fix—they expect you to explain why it went wrong, and how you’ll change it next time.
4. Assessment Structure: From Assignments to a Full Portfolio
CELTA assessments are clear and structured: four assignments and observed lessons. Simple.
Delta Module 2 includes:
- Four LSAs (Language Systems/Skills Assignments)
- Four Background Essays (2,000–2,500 words each)
- A Professional Development Assignment
- A complete portfolio
- Continuous reflection
And every piece connects to another.
It’s demanding—but it also feels like you’re building a legacy of your own growth.
5. Where It Takes You
CELTA opens the door.
Delta builds the corridor, the rooms, and the staircase.
CELTA enables you to teach in a range of settings and contexts.
Delta prepares you for:
- Academic coordination
- Teacher training
- Curriculum development
- Speaking at ELT conferences
- Writing and publishing in the field
If CELTA makes you a teacher, Delta makes you a specialist.
Final Thoughts
I’m still working through Delta Module 2, and I’ll be honest: it’s the most challenging professional development I’ve undertaken so far. But it’s also the most rewarding.
I’ve questioned everything—from how I correct errors to how I define success in a lesson.
So if you’ve done CELTA and you’re wondering, “What next?”—consider Delta. Not because it’s the next step, but because it’s the step that will change how you think, not just how you teach.
If you’re on the same path, I’d love to connect.
Whether you’re a CELTA graduate, a current Delta candidate, or just curious—drop your thoughts in the comments or reach out. Let’s grow together.
