Framework overlap

Does SSAE 18 cover OECD AI Principles?

You hold SSAE 18 and have been told to do OECD AI Principles. Here is how much overlaps, control by control.

63% of OECD AI Principles you already have

SSAE 18 already covers about 63% of OECD AI Principles, leaving 3 of 8 controls as genuinely new work.

Already covered 0 Likely covered 5 New work 3

No control in SSAE 18 maps directly to one in OECD AI Principles. Everything counted as covered is covered because both map to the same third standard, which is what a crosswalk is, but it is an inference rather than a lookup.

What is genuinely new work

Nothing in SSAE 18 reaches these. This is the list to scope.

OECDAI-4
Accountability, Lifecycle Coverage, Documentation, and Record-Keeping
OECDAI-6
Human Oversight, Redress, and Contestation Mechanisms
OECDAI-7
Third-Party AI Audit, Impact Assessments, and Metrics for Trustworthy AI

OECDAI-1

OECDAI-2

OECDAI-3

OECDAI-5
Data Governance, Training Data Quality, Privacy, and Bias Mitigation
OECDAI-8
AI Incident Reporting, Regulatory Compliance, Public Reporting, and International Cooperation

How this is calculated

Already covered means a mapping runs from a control in SSAE 18 to that control. Likely covered means no direct mapping exists but both frameworks map to the same control in a third standard. New work means neither. We keep those separate rather than adding them into one friendlier number, because blending them would present a two-hop inference as a verified fact.

Coverage is not symmetric. Run it the other way and you will get a different number; both are correct.

From 332,959 cross-framework control mappings across 723 frameworks, 531 of them verified against their source documents. It does not tell you that you are compliant: a mapped control means the two standards ask for the same thing, not that you have done it.
