Summary
This article helps candidates understand the differences between certification types and provides guidance on selecting the path that best aligns with their experience, goals, and career stage.
Overview
The Open Group Certification programs generally fall into two categories:
- Knowledge‑based certifications, which validate your understanding of a defined Body of Knowledge
- Experience‑based certifications, which validate your ability to apply that knowledge in real‑world practice
Choosing the right path depends on your background, your professional objectives, and where you are in your career journey.

2. Experience‑Based Open Professions Certifications
What They Are
Experience‑based certifications assess your real‑world professional practice. Instead of an exam, you submit evidence of your work, which is reviewed by qualified assessors.

3. How to Decide Which Path Is Right for You
Start with Your Career Stage
- Early‑career or transitioning: Knowledge‑based certifications provide a strong foundation.
- Mid‑career or senior practitioner: Experience‑based certifications validate your applied expertise.
Consider Your Learning Style
- Prefer structured study and exams → Knowledge‑based
- Prefer demonstrating real work and outcomes → Experience‑based
Think About Your Goals
- Building credibility quickly → Knowledge‑based
- Showcasing professional maturity → Experience‑based
- Long‑term progression → Many candidates pursue both over time
4. Combining Both Paths
Many professionals choose to earn both types of certification as they advance:
- Start with a knowledge‑based certification to establish foundational understanding.
- Progress to an experience‑based certification once you have accumulated real‑world practice.
This creates a complete, well‑rounded professional profile.
