CIAO Standard Document Registry

An authoritative index of all governing documents published under the CIAO Standard, for governance, assurance, and oversight practitioners.

1. Registry Overview

The CIAO Standard Document Registry is a structured, version-controlled index of all governing documents published under the CIAO Standard. Each entry is assigned a unique document reference—for example, C-AO/POL/ISP/001:2026—encoding the document type, tier, and year of issue to ensure consistent traceability. All documents are web-native and accessible without download, with each record displaying the current version, ACTIVE status, classification, and Review Date for full transparency.

Organised across six membership tiers—Commons, Core, Essential, Professional, Enterprise, and Conglomerate—the registry reflects the progressive scope of the standard. The foundational document set is active at Version 1.0, providing a complete baseline for governance, policy, and compliance frameworks. Whether establishing a new programme or auditing an existing one, this registry offers a clear, authoritative view of the controls and supporting materials that constitute the CIAO Standard, maintained with version integrity to support governance continuity and regulatory alignment.

3. Document Access and Use

All Commons through Professional tier documents in the CIAO Standard Document Registry are web-native and freely accessible without download, published under the Creative Commons Attribution-ShareAlike 4.0 International Licence (CC BY-SA 4.0). Enterprise and Conglomerate tier documents are issued under a proprietary licence and are accessible to credentialled members only. Each document may be cited using its unique document reference in the format C-AO/[TYPE]/[CODE]/001:YYYY. Users are encouraged to reference the registry as the single authoritative source for validated, current versions.

4. Review and Update Protocols

All CIAO Standard documents are subject to a scheduled annual review cycle. The Review Date field in the registry table indicates when each document is next due for assessment. Upon review, documents may be reissued at an incremented version number, amended in scope, or withdrawn. Any changes to document status or version are recorded in the Version History section below. The maintained-by field for all documents is www.c-ao.com.

5. Governance Context

The Document Registry sits at the centre of the CIAO Standard governance framework. All registered documents are published under the parent standard C-AO/STD/001:2026. Documents are organised across six membership tiers — Commons, Core, Essential, Professional, Enterprise, and Conglomerate — each tier building cumulatively on the one below. Commons through Professional tier documents are licensed under CC BY-SA 4.0. Enterprise and Conglomerate tier documents are issued under proprietary licence terms. Higher-tier documents reference and extend the policies and frameworks established at lower tiers, forming an integrated and interdependent governance system.
