Prompt Engineering Certification — Free & Publicly Verifiable
Master practical prompt design used by professional LLM engineers — not generic tips. Earn a publicly verifiable prompt engineering certificate. 100% free, no upsell.
What you can do after this course
- Write system, user, and tool prompts that consistently produce the output you want.
- Apply structured techniques: few-shot, chain-of-thought, self-critique, decomposition.
- Design retrieval-augmented prompts that ground answers in real data (RAG basics).
- Build prompt evals — measure quality, regressions, and cost per prompt change.
- Defend against prompt injection and unsafe outputs in production.
Who this prompt engineering course is for
Builders & engineers
You're shipping LLM features and want reliable prompts instead of "vibes-based" tuning.
Analysts & ops
You use ChatGPT or Claude daily for work and want repeatable, professional-grade output.
PMs & founders
You're scoping LLM features and need to understand what makes prompts reliable enough for production.
What you'll cover
- 1. How LLMs read prompts — tokens, context windows, sampling.
- 2. System / user / tool messages — the modern prompt anatomy.
- 3. Few-shot, zero-shot, and chain-of-thought patterns that actually generalize.
- 4. Decomposition & self-critique loops for hard reasoning tasks.
- 5. Structured output — JSON mode, schemas, function calling.
- 6. Retrieval-augmented prompting (RAG basics) — grounding answers in real data.
- 7. Prompt evals — how to measure quality, cost, and regressions per change.
- 8. Prompt safety — injection, jailbreaks, and safe-completion patterns.
- 9. Capstone exam — prove you can design and ship production-quality prompts.
A certificate anyone can verify
Pass the exam and you earn the GACS Prompt Engineering certificate with a unique ID and a public verification page. Add it to LinkedIn, your CV, or your portfolio.
Frequently asked questions
Is this prompt engineering certification really free?
Yes. The full study material, exam, and printable certificate are 100% free. No credit card, no per-query limit.
Is the certificate recognized by employers?
Every GACS certificate has a unique ID and a public verification page anyone (including recruiters) can use to confirm it. We don't claim accreditation we don't have — we offer transparent, verifiable proof you completed the work.
How long does it take?
Most learners finish the study material in 6–10 hours and pass the exam on the first or second attempt.
Do I need a coding background?
No. The core prompt-engineering material is language-agnostic and works for ChatGPT, Claude, Gemini, and open-source models. If you want to combine prompt engineering with code, the LLM Engineering diploma is the next step.
