There would be only a PRINCE2 Agile Practitioner level exam and certification. Candidates have to be PRINCE2 Practitioner certified before taking the exam.
This might limit the exposure of this new system, since it’s harder to get certified and it might discourage some people who might have otherwise get involved. It’s also harder for companies who want to adopt it: since they could ask their team members to get the Foundation level certificate to understand the general idea and have the common language; but they can’t.
It’s the current decision. Let’s hope AXELOS revises it.
