# ISO 14066

## ISO 14066

Complementing the organizational requirements of ISO 14065, [ISO 14066:2023](https://www.iso.org/standard/82544.html) (*Environmental information - Competence requirements for teams validating and verifying environmental information*) outlines the competence requirements of the personnel conducting the assessments. 

ISO 14066 provides validation and verification bodies (VVBs) with a clear framework against which to assess, develop, and maintain the capabilities of their personnel.

### Key Principles of ISO 14066

The requirements of ISO 14066 address competence across the different roles involved in a validation or verification engagement, including:

* **Knowledge requirements** cover the technical expertise that team members must possess, including familiarity with the applicable environmental information programme, quantitative and qualitative methods, and sector-specific knowledge relevant to the engagement.
* **Skills requirements** define team member capability requirements, including evidence gathering and evaluation, material issue identification, and the communication of findings. Additional skills requirements apply specifically to team leaders.
* **Demonstration and maintenance requirements** set out how competence must be initially evidenced and maintained over time through ongoing professional development and periodic evaluation.
