ISO 9001 is the world's most widely adopted quality management standard, and its next revision is at an advanced stage. The draft has reached Draft International Standard (ISO/DIS 9001:2025) and the standard will be published on 16 September 2026, followed by a transition period expected to be three years, projecting to around September 2029. The transition length is not yet officially confirmed; organisations should plan on that timeline but watch for the formal announcement from Global Accreditation Cooperation Incorporated, the body that took over the IAF's role on 1 January 2026.
The important thing to understand early is that ISO 9001:2026 is an evolutionary update, not a structural overhaul. The 2015 harmonised structure, process approach, and risk-based thinking all remain intact. What changes is the level of explicitness on quality culture, climate context, and the separation of risks from opportunities, plus a substantially expanded informative annex (Annex A).

Once ISO 9001:2026 is formally published, the transition clock starts. Organisations certified to ISO 9001:2015 will need to transition within the expected three-year window. Because the structural changes are modest, the practical effort for a certified organisation is mainly an awareness and understanding exercise, not a wholesale re-documentation of the quality management system.
That said, do not underestimate the understanding gap. Auditors, process owners, and certification consultants who assume they already know the standard are precisely the group most at risk of missing the intent of the new requirements. Demonstrating genuine comprehension, not just familiarity, is what an ISTO Test of Understanding is designed to measure.
Quality culture and ethical behaviour
The most philosophically significant addition in ISO 9001:2026 is an explicit requirement for top management to promote a quality culture and ethical behaviour within the organisation. In the 2015 edition, quality culture was implicit, expected but not named. The 2026 revision makes it a formal expectation in clause 5.1 (leadership and commitment), with a corresponding awareness requirement in clause 7.3 so that employees understand what quality culture means and how their work contributes.
This matters because culture cannot be documented into existence. An organisation can have immaculate procedures and still have a culture that cuts corners under pressure. Recognising this, the revision moves quality culture from a hoped-for by-product to an explicit management responsibility. Examiners and auditors will increasingly look for evidence that the culture expectation is understood at all levels, not just written into a policy statement.
| Topic | ISO 9001:2015 | ISO 9001:2026 |
|---|---|---|
| Quality culture | Not explicitly required — implicit in leadership expectations | Clause 5.1 requires top management to actively promote quality culture and ethical behaviour |
| Employee awareness | Clause 7.3: awareness of quality policy and QMS contribution | Clause 7.3 extended to include awareness of quality culture expectations |
| Climate change | Not present in 2015; added by Amd 1:2024 to clauses 4.1 and 4.2 | Formally integrated into the organisational context clauses — 4.1 and 4.2 |
| Risk and opportunity | Clause 6.1 addresses risks and opportunities together | Clause 6.1 splits into sub-clauses so risks and opportunities are handled distinctly |
| Supplementary guidance | Informative Annex A clarifying new structure and terminology; broader guidance relied on external ISO 9000 family documents | A substantially expanded informative Annex A clarifying structure, terminology and clause intent |
| Terminology | Many quality-specific terms cross-referenced to ISO 9000 | More QMS-specific terms built directly into the standard itself |
Climate change and sustainability context
ISO 9001:2015 was published before climate change was a mainstream organisational risk lens. The 2024 Annex SL amendment (Amd 1:2024) bridged that gap by adding climate-change considerations to the organisational context clauses across 31 management-system standards, including ISO 9001. ISO 9001:2026 takes the next step by formally integrating those requirements directly into the revised standard, rather than leaving them as an amendment bolt-on.
In practice this means:
- Clause 4.1 requires the organisation to determine whether climate change is a relevant issue for its context. It is an explicit consideration when scanning the internal and external environment.
- Clause 4.2 extends the interested-parties analysis to note that interested parties can have climate-related requirements and expectations.
For most organisations this will not be a seismic change in day-to-day quality operations. What it does require is that the environmental scanning and interested-party analysis are done thoughtfully, with climate explicitly on the agenda, and that the conclusions are documented so they can be demonstrated during audit.
Risk vs opportunity — a clearer split
In ISO 9001:2015, clause 6.1 treated risks and opportunities in a single combined clause, which sometimes led to confusion about whether an organisation needed to track them separately or together. ISO 9001:2026 addresses this by splitting clause 6.1 into distinct sub-clauses for risks and for opportunities.
This is a practical clarification rather than a fundamentally new concept. Most mature QMSs already treat risks and opportunities separately in practice. The revision simply aligns the standard's language with how organisations actually operate, and makes it unambiguous that the two must each receive deliberate attention. From an exam and audit perspective, expect questions to become more specific about whether a given action plan addresses a risk, an opportunity, or both.
The expanded Annex A
One of the more notable structural changes in ISO 9001:2026 is a substantially expanded informative Annex A, based on the current draft. The 2015 edition already carried an informative Annex A clarifying its new structure, terminology and concepts; the 2026 revision broadens that guidance considerably, drawing in interpretive material that previous editions largely left to the wider ISO 9000 family (particularly ISO 9004) and bringing more of it inside the standard itself.
The annex is informative (it does not add requirements), but it does clarify intent, terminology, and how clauses relate to each other. This is particularly useful for complex areas like the quality-culture expectation and the risk/opportunity split, where practitioners have historically relied on third-party interpretations. Having authoritative guidance inside the standard reduces that ambiguity.
What this means for candidates and organisations
For candidates preparing for an ISTO Test of Understanding, the 2026 revision is a prompt to review the new and clarified requirements carefully, even if the 2015 edition remains in force at the time of your exam. Understanding the intent behind quality culture, the explicit climate context, and the risk/opportunity distinction will sharpen comprehension of the 2015 requirements too. They were always implied; the 2026 revision just makes them explicit.
For certified organisations, the preparation work is straightforward:
- Map the gaps — compare your current QMS documentation and awareness training against the new and revised clauses, particularly 5.1, 6.1, and 7.3.
- Update training — ensure process owners and internal auditors understand what quality culture and ethical behaviour mean in practice, not just on paper.
- Review your context analysis — confirm that climate change is formally considered in clauses 4.1 and 4.2, with the conclusions documented.
- Revisit risk registers — check that risks and opportunities are treated distinctly, with separate action plans where appropriate.
