Should You Take ITIL® 4 or ITIL® 5?

Start With Your Employer's Requirement

Before weighing anything else, check whether your employer, client contract, or job posting specifies a version. Some organizations standardize on a particular certification for procurement or compliance reasons, and this single factor should override general advice. If there's no specific requirement, the rest of this guide applies.

Decision Factor: Career Stage and Timeline

If you're early in your career or have flexibility in timing, ITIL® 5 Foundation is generally the safer long-term bet — it's the current version, and certifications tend to hold more relevance the newer they are relative to when you're job-searching. If you need a certification quickly for an imminent job requirement and you're already deep into ITIL® 4 study materials, finishing that path may be faster than switching mid-preparation.

Decision Factor: What Your Team or Industry Uses

If you work alongside colleagues, consultants, or vendors who are currently certified in and speaking the language of ITIL® 4, there's a practical argument for matching that — at least for now. Conversely, if your organization is actively adopting ITIL® 5 concepts like the Product and Service Lifecycle Model or its AI governance guidance, sitting ITIL® 5 Foundation directly aligns better with that direction.

Decision Factor: How Much of the New Content You Actually Need

ITIL® 5 Foundation's newest material — AI governance, the AI Capability Model, the renamed lifecycle model — reflects where the industry is heading. If your role or industry is already engaging with AI governance questions, that content has direct relevance beyond just passing an exam. If your day-to-day work is squarely traditional IT service management with no AI governance angle, the practical difference may matter less to you day-to-day, even though ITIL® 5 still covers the same core service management fundamentals.

Why Not Just Wait and See?

Some candidates consider delaying certification altogether to "wait for things to settle." This isn't necessary — ITIL® 4 Foundation remains fully valid and available, and PeopleCert has committed to a minimum 12-month period where both are supported. There's no evidence either certification is at risk of losing recognition in the near term, so waiting mainly costs you the career and resume benefit of being certified sooner.

Comparing the Two Paths for First-Time Candidates

Real-World Example

A candidate starting their first ITIL® certification with no employer mandate and no existing study materials will generally do better sitting ITIL® 5 Foundation directly — it's the current version and covers the newest content. By contrast, a candidate who's three weeks from a job interview that explicitly lists "ITIL® 4 Foundation" as a requirement, and who has already started studying ITIL® 4 materials, should finish that path rather than switching.

Why This Matters

Making this decision deliberately, rather than defaulting to whichever exam you've heard of first, matters because:

• It avoids wasted study time on materials for the wrong exam version
• It aligns your certification with actual employer or industry requirements rather than assumptions
• It clarifies that neither certification is at risk of becoming invalid in the near term, removing "wait and see" as a real option

Common Misconceptions

The most common misconception is that ITIL® 4 Foundation is being phased out immediately and is therefore a risky choice. As of 2026, ITIL® 4 Foundation remains fully available with no announced retirement date, and PeopleCert has committed to a minimum 12-month coexistence period.

A second misconception is that ITIL® 5 Foundation is dramatically harder because it's newer. Per PeopleCert's official exam details, both exams share the same 40-question, 60-minute, 65%-pass-mark format — the difference is syllabus content, not difficulty.

Memory Trick

Think:

Check your employer first. Default to ITIL® 5 second. Don't wait for a reason.

If nothing external dictates your choice, ITIL® 5 Foundation is the sensible default for a first-time candidate in 2026.

Key Takeaways

• Check your employer's or industry's specific requirement first — it should override general advice.
• ITIL® 5 Foundation is the sensible default for most first-time candidates with no specific requirement, since it covers the current, newest content.
• ITIL® 4 Foundation remains fully valid and available, with no announced retirement date and a minimum 12-month coexistence commitment from PeopleCert.
• Both exams share the same format, question count, time limit, and pass mark — the real decision factor is content relevance and requirements, not difficulty.
• There's no practical benefit to delaying certification altogether while "waiting to see" which version wins out.
