The primary purpose of the first level called “Foundation” is to demonstrate knowledge of PPPs as described in the PPP Guide, the set of experience on which the PPP certificate is based.
You can find more information in the Program Guide.
The Foundation exam tests whether a candidate has sufficient knowledge and understanding of the PPP Guide to act as an informed team member of a PPP finance project. The Foundation certification is a pre-requisite for the Practitioner certifications. The base of this examination is the Chapter 1 of the PPP Guide (“PPP Introduction and Overview”).
