- **Jurisdiction**: United States
- **Category**: safety_testing
- **Binding**: No
- **Provision**: MEASURE function

## In brief

Measure and test trustworthiness characteristics (Measure) is a voluntary measure under the NIST AI RMF in the United States (MEASURE function). Measure covers selecting metrics and test methods, evaluating validity, safety, security, resilience, explainability, privacy, fairness and bias, and monitoring these over time, including through independent review and red-teaming for generative AI.

## What the duty requires

Measure covers selecting metrics and test methods, evaluating validity, safety, security, resilience, explainability, privacy, fairness and bias, and monitoring these over time, including through independent review and red-teaming for generative AI.

## What an organisation does about it

Define a test plan with metrics for each trustworthiness characteristic and record results.

## Controls that meet this duty

- Adversarial and red-team testing for generative AI (supports): https://aipolicytracker.org/controls/genai-red-team-testing
- Accuracy, robustness, fairness and security testing (satisfies): https://aipolicytracker.org/controls/accuracy-robustness-security-testing
- Post-deployment monitoring and drift detection (supports): https://aipolicytracker.org/controls/post-market-monitoring-and-drift-detection
