About the ChatGPT badge
Show employers and clients you actually know ChatGPT — prompts, iteration, model limits and all — with a 15-minute AI-graded oral exam and a shareable badge.
The Plume ChatGPT badge certifies how well you use the world's most popular generative AI tool in a real professional setting. During a 15-minute oral exam, an AI examiner questions you on how you build prompts, iterate on outputs, navigate advanced features like Custom Instructions, persistent Memory, the Code Interpreter, and web browsing, and how clearly you understand the model's limits — hallucinations, context window constraints, and the tradeoffs between GPT-4o, o1, and o3. A second AI, Claude Opus, reads the full transcript and produces a score out of 100 plus a level: Novice, Proficient, Advanced, or Expert.
Unlike a self-declared LinkedIn skill or a multiple-choice quiz you can game in five minutes, this is a live oral. The AI examiner follows up, probes your reasoning, and quickly spots whether you understand why a prompting technique works or whether you're just repeating something you saw in a YouTube thumbnail. The detailed report breaks down every evaluation dimension — prompt quality, iteration ability, awareness of model limits — with direct quotes from your answers.
This badge is built for anyone who already uses ChatGPT daily: writers, developers, project managers, consultants, marketers, and career-switchers who picked up the skill on their own and want an external, objective proof of it before a job interview, a freelance pitch, or a team onboarding.
What this badge evaluates
Here are the concrete dimensions the AI examines during the 15-minute oral.
Prompt architecture
Writing structured prompts with an explicit role, context, output format and constraints to get consistent, precise results rather than vague one-liners that produce random outputs.
Iteration and refinement
Knowing how to follow up intelligently, decompose complex tasks into sub-steps, and progressively sharpen the output without scrapping the whole conversation and starting over.
Awareness of model limits
Spotting hallucinations, understanding the context window, knowledge cutoff dates, and the specific task types where ChatGPT is likely to produce confidently wrong answers.
Advanced features
Using Custom Instructions, persistent Memory, the Code Interpreter for file analysis and chart generation, web browsing with citations, and building or using Custom GPTs for specific workflows.
Long-context management
Structuring long conversations, injecting documents effectively, managing coherence drift over extended threads, and knowing when to open a fresh chat versus continuing an existing one.
Real-world use cases
Applying ChatGPT to concrete professional tasks: drafting, document summarization, code generation, data analysis, translation, and structured reformulation with editorial constraints.
Privacy and data hygiene
Knowing what data to never paste into ChatGPT, understanding the difference between Free, Plus, Team, and Enterprise plans in terms of data retention and training opt-outs.
Choosing the right model
Distinguishing GPT-4o, GPT-4o mini, o1, and o3 by task type — speed, deep reasoning, cost efficiency — and justifying that choice in a professional context.

15% of scoreHands-on knowledge of Custom Instructions, Memory, the Code Interpreter, Custom GPTs, and web browsing with sources — beyond just knowing they exist.
Relevance of professional use cases
10% of scoreAbility to connect ChatGPT features to real work problems and to assess honestly when the tool adds genuine value versus when a different approach would be more effective.
How the oral exam unfolds
A Plume session takes about 20 minutes, from tech check to badge delivery.
- Step 1
Tech check (1 min)
You join the session via a browser link. The AI checks your mic, confirms your connection is stable, and walks you through the format before the clock starts.
- Step 2
Warm-up — your ChatGPT setup (2 min)
The AI examiner asks how long you've been using ChatGPT, in what professional context, and which version or plan you use most. No trick questions — just getting you talking naturally.
- Step 3
Core questioning — prompts, limits, features (10 min)
The heart of the exam. The AI digs into how you build prompts, how you react when the model hallucinates, how you use the Code Interpreter or Custom GPTs, and your understanding of the differences between GPT-4o, o1, and o3.
- Step 4
Practical scenario (2 min)
The examiner gives you a real-world situation — for example: 'You need to analyze a 500-row CSV in ChatGPT — walk me through your approach' — and evaluates your reasoning on the spot.
- Step 5
Score and badge (within 24 h)
Claude Opus analyzes the transcript and generates your score out of 100, your level, a detailed per-criterion report, and a public badge URL you can share on LinkedIn with one click.
The 4 proficiency levels
Your score out of 100 translates into a level a recruiter can grasp at a glance.
Novice
Score 0-39You use ChatGPT occasionally with simple, unstructured prompts. You haven't explored advanced features yet and have limited awareness of when and how the model makes mistakes.
Proficient
Score 40-59ChatGPT is part of your daily workflow. You write prompts with a role and context, know how to follow up when answers fall short, use Custom Instructions, and catch the most obvious hallucinations.
Advanced
Score 60-79You use the Code Interpreter to analyze data and build charts, create Custom GPTs for specific team workflows, manage long conversations with structure, and deliberately choose between GPT-4o and o1 based on the task.
Expert
Score 80-100You design complex prompt systems, train others on ChatGPT, benchmark models on objective performance and cost criteria, and integrate ChatGPT into automated workflows or hybrid API pipelines.
Who this badge is for
No degree or years of experience required to take the badge. Here are the profiles it makes the most sense for.
Consultant or project manager
You use ChatGPT to synthesize reports, draft deliverables, and cut repetitive work. This badge shows clients your usage is structured and intentional, not just vibes-based copy-pasting.
Developer or data analyst
You rely on ChatGPT for code generation, debugging, and data analysis via the Code Interpreter. The badge proves you know how to get reliable outputs, not just plausible-looking ones.
Writer or content creator
ChatGPT is your editorial co-pilot. This badge demonstrates you know how to direct it — voice, editorial constraints, iteration — rather than publishing its raw output.
Student or career-switcher
You taught yourself ChatGPT and need a tangible proof of your level before a job interview or before launching a freelance profile in an AI-heavy market.
Trainer or in-house AI lead
You roll out ChatGPT across your team or run internal training sessions. This badge gives your AI champion role external, objective credibility.
Concrete use cases
Where and how your ChatGPT badge will help you day to day.
Job interview
A recruiter asks if you're comfortable with AI tools. You share your Plume badge URL with your score and Advanced level — concrete proof that replaces the hollow 'yes, I use ChatGPT'.
Freelance pitch
You offer writing or AI automation services. The badge on your Upwork or LinkedIn profile reassures the client about your actual skill level and supports your rate.
