Frequently Asked Questions

As an example: If a Milestone contains 10 PCI DSS requirements, and an entity identifies 5 requirements as “N/A”, 3 requirements a “No” (not in place), and 2 requirements as “Yes” (in place), the resulting calculation would be:

• For v3.1 of the Prioritized Approach: The calculation considered 7 requirements (the sum of “N/A” and “Yes” responses) as “in place” out of the total 10 requirements, resulting in a score of 70% for that milestone.
• For v3.2 of the Prioritized Approach: Because the 5 “N/A” responses are excluded from the calculation, there will be 2 requirements (“Yes” responses) identified as “in place” out of the 5 applicable requirements, resulting in a score of 40% for that milestone.

This example calculation is also summarized in the following table:

While this change simplifies and improves accuracy of the calculation process, the result is that a non-compliant merchant may appear to show a “drop” in compliance when using the Prioritized Approach Tool for PCI DSS v3.2 when compared to their report for PCI DSS 3.1 (or earlier), even if they report the same requirements as being in place, not in place, and not applicable.  Organizations and their compliance reporting entities will need to take this into consideration when comparing results from the Prioritized Approach v3.2 to results from previous versions.

Entities that are able to report all applicable PCI DSS controls as being in place will achieve an Overall result of 100%.
