ITIL 4 vs ITIL 5 Foundation: Which Should You Take in 2026?

For six years, "should I do ITIL?" had one answer: ITIL 4 Foundation. That changed in February 2026, when PeopleCert released ITIL Version 5 — the first full refresh of the framework since 2019. Both Foundation exams are bookable today, both are 40 questions in 60 minutes at a 65% pass mark, and both carry the same name on your CV. So which one should you actually sit? This guide explains what changed, what stayed, and how to choose without wasting a fee.

The short answer

If you are certifying for the first time in 2026 and have no deadline forcing your hand, take ITIL Version 5 Foundation. It is the current framework, it will stay current longer, and the exam is no harder. Take ITIL 4 Foundation instead if a specific employer, training package or funded course names it, or if you have already studied ITIL 4 material and want to sit while it is fresh. If you already hold ITIL 4 Foundation, you do not need to retake Foundation to move into higher Version 5 modules.

What actually changed in ITIL 5

The service value chain became a lifecycle model

This is the structural change. ITIL 4's service value chain had six activities: plan, improve, engage, design and transition, obtain/build, and deliver and support. ITIL 5 replaces it with the Product & Service Lifecycle Model, which has eight: discover, design, acquire, build, transition, operate, deliver and support.

It is not just renaming. Two distinctions in particular are new and are heavily examined:

• Discover is now an explicit first activity — understanding demand and opportunity before you design anything.
• Operate and Support are separated. Operate is running and maintaining the product in the live environment so it keeps performing. Support is helping users — answering questions, resolving their issues. In ITIL 4 both sat inside a single "deliver and support" activity. Expect at least one exam question that hinges on telling them apart.

"Service value system" became "ITIL Value System"

The concept is recognisable: opportunity and demand go in, value comes out, with governance and continual improvement wrapped around it. The naming and framing have been modernised, and the emphasis has shifted from services to digital products and services — reflecting how most organisations now actually deliver.

AI governance is genuinely new

ITIL 5 adds AI governance as first-class content, built around accountability (who is answerable when an AI-assisted decision goes wrong), transparency (can you explain how the decision was reached) and risk management (managing the chance of biased, unsafe or undesirable output). This is the clearest signal of why the version was refreshed at all, and it is examinable.

What stayed the same

Reassuringly, much of it:

• The four dimensions — organisations and people; information and technology; partners and suppliers; value streams and processes. Unchanged.
• The seven guiding principles — focus on value; start where you are; progress iteratively with feedback; collaborate and promote visibility; think and work holistically; keep it simple and practical; optimise and automate. Titles unchanged from ITIL 4.
• Core practices — incident management, problem management, change enablement, service desk and the rest remain the operational backbone.
• Continual improvement — still central, still examined.

If you have studied ITIL 4, a very large share of what you learned still applies. The genuinely new material is the lifecycle model, the AI governance content and the digital-product framing.

The exams are identical in shape

This surprises people who assume a new version means a harder exam. Both Foundation papers are:

• 40 multiple-choice questions
• 60 minutes
• 65% to pass — 26 correct out of 40
• Closed book: no notes, no manual, no reference material
• No prerequisites

Both are recall-and-comprehension exams. Neither asks you to apply the framework to a complex scenario — that comes at the levels above Foundation. Ninety seconds per question is comfortable if you know the material and uncomfortable if you are reasoning from first principles, which is the real argument for question practice over re-reading.

Confirm the current format, languages and fees on PeopleCert's website before booking — they are the awarding body and the only authoritative source.

So which should you sit?

Take ITIL Version 5 Foundation if…

• You are certifying for the first time and have no external constraint.
• You want the credential to stay current as long as possible.
• Your organisation is actively grappling with AI governance — the new content is immediately applicable, not just examinable.
• You intend to progress to higher modules and would rather enter the Version 5 path directly.

Take ITIL 4 Foundation if…

• A job advert, employer or funded training package specifically names ITIL 4.
• You have already worked through ITIL 4 material and sitting soon costs you less than restudying.
• Your organisation runs its service management on ITIL 4 and you want the certificate to match the language your colleagues use daily.

One thing you do not need to worry about: an ITIL 4 certificate does not stop being valid when a new version appears. PeopleCert has confirmed the two frameworks run in parallel and has not published a retirement date for ITIL 4. You will see specific sunset dates quoted on third-party sites — treat them as speculation until PeopleCert announces one. If you already hold ITIL 4 Foundation, you also do not need to repeat Foundation to enter eligible higher-level Version 5 modules.

How to pass either Foundation exam

1. Learn the structure before the detail. Whichever version you take, get the shape in your head first — four dimensions, seven guiding principles, the value system, then the lifecycle activities or value chain. Individual practices are much easier to remember once they have somewhere to attach.

2. Drill the definitions that are deliberately confusable. ITIL exams routinely test pairs that sound similar. Incident versus problem. Change enablement versus release management. Service desk versus support. In Version 5, operate versus support. These are free marks if you have separated them and lost marks if you have not.

3. Do not rote-learn the guiding principles as a list. Questions describe a behaviour and ask which principle it illustrates. "Reuse what already exists rather than rebuilding" is start where you are. "Optimise the process before you automate it, or you automate waste" is optimise and automate. You need to recognise them in action, not recite them in order.

4. Sit timed 40-question mocks. The exam is short and the clock is the main pressure. Practising at the real length turns pacing into a non-issue.

5. Check the version stamped on every resource you use. This is the single biggest risk in 2026. Material written for ITIL 4 will teach you a six-activity value chain that does not exist in Version 5, and will not mention AI governance at all. Make sure everything you revise from names the version it targets.

Frequently asked questions

When was ITIL 5 released?

PeopleCert released ITIL Version 5, including the Foundation module, in February 2026, as the successor to ITIL 4.

Is ITIL 4 being retired?

Not yet. ITIL 4 Foundation remains available to book and PeopleCert has not published a retirement date. The two versions currently run in parallel.

Is my ITIL 4 certificate still valid?

Yes. A new version does not invalidate an existing certificate. If you hold ITIL 4 Foundation you also do not need to retake Foundation to progress into eligible Version 5 modules.

What is the ITIL 5 Foundation pass mark?

65% — 26 correct answers out of 40, in 60 minutes, closed book. ITIL 4 Foundation uses the same format and pass mark.

What is the main difference between ITIL 4 and ITIL 5?

ITIL 4's six-activity service value chain is replaced by an eight-activity Product & Service Lifecycle Model — discover, design, acquire, build, transition, operate, deliver, support — with Operate and Support now separated. ITIL 5 also adds AI governance and reframes the content around digital products and services. The four dimensions and seven guiding principles carry over unchanged.

Do I need experience in IT service management to take Foundation?

No. Neither Foundation exam has prerequisites. It is designed as an entry point, and plenty of candidates come from project management, operations or support backgrounds rather than ITSM.

The bottom line

ITIL Version 5 is an evolution, not a rebuild. The dimensions and guiding principles you may already know are intact; the value chain has been reworked into a fuller lifecycle model, and AI governance has been added because service management genuinely needed it. The exams are the same shape, so the choice comes down to which version your employer speaks and how long you want the certificate to stay current.

PassNova keeps ITIL 5 Foundation and ITIL 4 Foundation as separate question banks precisely because mixing them is how people learn the wrong value chain. Each has 200 exam-style questions and six timed mocks with an explanation on every answer; the first 15 questions of either are free to try. If you are building a broader service-and-delivery profile, PRINCE2 Foundation, DevOps Foundation and COBIT Foundation sit naturally alongside it.
