What changes with the 2026 edition
Structure aligned with the 17000 family
The 2026 edition is restructured to align with the format and terminology of the ISO/IEC 17000 family and the common CASCO elements, and introduces a new Annex B explaining how activities, processes, assessments, examinations and schemes relate to one another.
Explicit requirements for AI
The most substantive new content introduces a definition and requirements for the use of artificial intelligence in the certification of persons: human oversight and validation of AI-generated results.
Transition window
The sector’s usual practice for revisions of this scope is a two-to-three-year transition from publication. IAC runs its own documentary transition through 2026, with a published quarterly review.
The IAC transition
What IAC reviews
Schemes, public language, internal criteria and training and assessment references, without transferring protected normative text or exposing reserved procedures. Internal adoption v2026.05 · quarterly review (next: 2026-Q3).
Standards & Research →What happens to current registry entries
Published registry entries keep the validity declared in their record: status, scope and expiry date are the governing data and are consulted by code. Any change of status is recorded in the public traceability.
Verify a code →How AI is governed in assessment
Standing IAC rule: AI explains, it does not decide. Assisted readings are indicative; status, scope and validity are set by the file with a documented human decision. This principle is consistent with the human oversight required by the 2026 edition.
Scope and limits →IAC operates a private registry of verifiable technical evidence; the reference to ISO/IEC standards is one of reading and criteria, with no copying of requirements and no substitution of competent bodies.
