The Problem

AI Skills Are Invisible.
We Make Them Measurable.

Everyone claims they can "prompt AI effectively." But until now, there was no standard, no measure, no credential — just vibes.

🎭

No Standard Exists

Prompt engineering has no recognized curriculum, no proficiency standard, and no industry benchmark — so skill claims are unverifiable.

📋

Subjective Certifications

Existing AI certs test theory knowledge, not practical execution. An MCQ about "what is a prompt" proves nothing about real capability.

🔒

Skills Are Siloed

Employers can't assess candidates. Freelancers can't differentiate. Teams can't identify skill gaps. There's no shared language for AI proficiency.

Assessment Method

Three-Layer Assessment.
One Definitive Score.

Our scoring formula: Score = (KBA × 30%) + (PPA × 60%) + (PSV × 10%)

1
KBA · 30%

Knowledge-Based Assessment

Adaptive multiple-choice questions covering prompt principles, LLM behavior, and theory. 60 questions, 45 minutes. Covers all 5 PECMAS pillars.

2
PPA · 60%

Practical Prompt Assessment

Real tasks in a live sandbox. You write prompts, AI executes them, and our LLM judge scores outputs on a 9-axis PEEM rubric. Accuracy, tone, creativity, efficiency.

3
PSV · 10%

Peer Sample Validation

Community cross-review of prompt samples. Blinded peer scoring validates the LLM judge and surfaces edge cases. Builds community quality standards.

Proficiency Levels

Five Levels.
One Clear Path.

PECMAS Framework

Five Pillars of
Prompt Competency

Built on the open PECMAS standard. Every assessment question maps to one or more pillars, ensuring comprehensive, multi-dimensional measurement.

✍️
P

Prompt Design

Clarity, structure, instruction specificity, format control, constraint definition. The craft of writing prompts that work first time.

⚡
E

Execution & Iteration

Testing, debugging, systematic refinement, prompt versioning, A/B comparison. Turning prompts into reliable systems.

🧩
C

Context Management

Memory strategies, context windows, document injection, conversation flow, retrieval-augmented generation patterns.

🧠
M

Meta-Cognition

Model theory, emergent behavior understanding, bias awareness, failure mode recognition, calibrated self-evaluation.

🤖
A

Agentic Prompting

Multi-step pipelines, tool use orchestration, autonomous agents, prompt chaining, delegation patterns for complex workflows.
