The Open Group Open Professions program provides globally recognized, experience‑based certifications for professionals working in architecture, data science, technical specialisms, and trusted technology.

This article provides an overview of the program and where to find further information.
How Open Professions Certification Works
Open Professions certifications are experience‑based.
There are no training requirements, tests, or exams.
Instead, each candidate is evaluated against a defined set of Conformance Requirements, which measure:
- Professional skills
- Practical experience
- Breadth and depth of capability
- Leadership (for higher levels)
Assessment is conducted through a peer‑based board interview process, ensuring that certification reflects real‑world professional performance.
