The G-Series Governance Framework provides a structured basis for examining how board, institutional, technology and AI governance arrangements are documented, attributed, reviewed and evidenced in practice. The standards are designed to complement applicable law, regulation, recognised standards, internal governance systems and professional assurance. They do not replace those arrangements or confirm compliance with them.
Governance frameworks commonly describe the structures, responsibilities and controls that organisations should establish.
The G-Series focuses on the related evidential question: what records, decisions, oversight activity, control ownership, escalation evidence and review history demonstrate that those arrangements operate within a defined scope? IGSB applies the G-Series to submitted documentary information. Findings remain limited to the evidence provided and do not establish that a control operates effectively outside the reviewed material.
G1 examines the evidence supporting board-level oversight, decision authority, accountability, challenge and governance traceability.
Its scope may include defined board responsibilities, delegated authority, documented decisions, oversight records, escalation arrangements, conflict management, review and challenge, and accountability for material governance matters.
Explore G1 Board GovernanceG2 examines the evidence supporting organisational governance structures, delegated responsibility, control ownership, institutional oversight and accountability. Its scope may include governance roles and responsibilities, operational ownership, delegated decision-making, internal controls, risk and issue escalation, management oversight, governance reporting, and institutional review arrangements.
Explore G2 Institutional GovernanceG3 examines the governance evidence supporting technology, automated decision-making and AI-enabled systems. Its scope may include defined system ownership, decision authority, human oversight, risk acceptance, change control, incident and escalation records, vendor and third-party governance, monitoring and review, and traceability of material decisions.
Explore G3 Technology & AI GovernanceG1, G2 and G3 address different but connected levels of governance. G1 considers board authority and oversight. G2 considers institutional structures, delegated responsibilities and organisational controls. G3 considers the governance evidence surrounding technology and AI-enabled systems.
A defined review may draw on one standard or more than one standard, depending on the organisation, system, use case, evidence question and agreed scope. The use of multiple standards does not imply that every domain is assessed or that every enquiry proceeds into a formal engagement.
IGSB records evidence positions using four controlled classifications: Not submitted, Not evidenced, Partially evidenced, and Evidenced within submitted information. These classifications describe the submitted evidence position only. They do not confirm legal compliance, technical safety, operational effectiveness, regulatory approval, audit assurance or certification.
Information required for the defined evidence question has not been provided.
Submitted information does not evidence the relevant governance requirement or control.
Submitted information provides some relevant evidence, but material elements remain incomplete, unclear or insufficiently traceable.
The relevant governance requirement or control is evidenced within the material reviewed.
The G-Series is applied through controlled written routes, which may include a written enquiry, an evidence request, an AI Governance Evidence Gap Map, a G-Series AI Governance Evidence Passport, a G3 Readiness Snapshot, or a separately authorised controlled pre-assessment. IGSB determines the appropriate route after considering the enquiry, defined scope, available evidence, institutional capacity and applicable boundaries. Not every enquiry proceeds through every stage.
An initial written enquiry identifying the organisation, system or use case, followed by a written evidence request where required.
A structured review mapping submitted governance evidence against the relevant G-Series standard and identifying evidence gaps.
A G-Series AI Governance Evidence Passport or G3 Readiness Snapshot may be produced, structuring the evidence position for further consideration.
Where IGSB has separately determined eligibility, a controlled pre-assessment may follow written engagement and acceptance.
Organisations may also review the G-Series AI Governance Evidence Readiness Programme, which brings together the framework, evidence protocol and readiness review pathway.
View the AI Governance Evidence RouteThe G-Series is not a substitute for law, regulation, recognised technical or management-system standards, internal governance responsibility, professional audit or specialist assurance.
It may help organisations organise and examine the documentary evidence supporting governance arrangements within a defined scope.
Existing frameworks may describe what should exist. The G-Series helps assess what can be evidenced within submitted information.
IGSB does not presently issue certification, accreditation, regulatory approval, legal opinions, audit assurance or confirmation of compliance. Any Evidence Gap Map, Governance Evidence Passport, Readiness Snapshot or controlled pre-assessment remains limited to the agreed scope and the information submitted. Future certification activity, if developed, would require separately established governance, independence, decision-control and quality-assurance arrangements. It must not be presented on this page as a current service or operating capability.
Organisations may submit a written enquiry identifying the relevant organisation, system, vendor platform, internal use case or operational technology environment and the governance evidence question being considered. Do not submit confidential, privileged, personal or operationally sensitive evidence at initial contact. IGSB will confirm any controlled evidence-submission route in writing.
