NEBOSH has fully revised the IGC for 2026. New syllabus, new exam format, new marking system. If you're an international HSE professional considering NEBOSH or already working towards it: here's what's changing — and what it means for you in practice.
What has changed?
The 2026 revision affects the naming, the content and the way you're assessed. The key changes at a glance:
- The old names IG1 and IG2 are replaced by GIC1 and GIC2.
- IG1 was a 2-hour written exam — GIC1 is now a 24-hour open-book exam.
- IG2 only gave "Met" or "Not Met" — GIC2 now gives a detailed score per component (hazard identification, risk assessment, recommendations).
- The old syllabus deadline: 6 August 2026 is the last exam date for IG1 and IG2.
| Item | Old (IG1/IG2) | New (GIC1/GIC2) |
|---|---|---|
| Name | IG1 / IG2 | GIC1 / GIC2 |
| Theory exam | 2-hour written | 24-hour open-book |
| Practical marking | Met / Not Met | Score per component |
| Last old exam date | 6 August 2026 | GIC only after that |
GIC1 — the open-book exam
GIC1 is the biggest change. The two-hour written exam gives way to an open-book exam with far more time and where you may use all your material.
- You have 24 hours to complete the exam.
- You may use all your study material.
- The questions are scenario-based — you have to reason, not memorise.
- A short verification interview may follow (2–3 questions).
- The final grade is based on GIC1 (Pass / Credit / Distinction).
Practise now with our free IG1 practice questions — the material maps directly onto the new GIC1 exam.
Important: open book doesn't mean the exam is easier. Precisely because you can look everything up, the questions test whether you genuinely understand the material and can apply it to a realistic work situation.
GIC2 — the practical assignment
GIC2 replaces IG2 and remains a practical assignment, but the way it's marked changes significantly.
- You produce a risk assessment of your own workplace.
- New: you receive a detailed score per component.
- Both units (GIC1 and GIC2) must be passed for the certificate.
- GIC2 does not count towards the final grade, but is still mandatory.

What if you're still working on the old system?
Mid-way through the old route? What you should do depends on your situation.
- Already passed IG1? Then IG2 must be completed before 6 August 2026.
- Not started yet? Then you begin directly with the new GIC1/GIC2 system.
- Not sure? Contact SafetyXAcademy — we'll look at your best route together.
What does this mean for you as an international HSE professional?
For most HSE professionals the revision works out positively, provided you prepare well.
- The new system is fairer: you can offset weaker components with stronger ones.
- Open book doesn't mean easier — the questions require insight and your own reasoning.
- English-taught coaching at SafetyXAcademy helps you truly understand the exam material, not just memorise it.

With an open-book exam and scenario questions, the difference between "knowing the words" and "understanding the material" is decisive. That's why our NEBOSH IGC course focuses on real understanding of the English exam material.
Frequently asked questions
Is the new NEBOSH IGC harder than the old one?
Not necessarily harder, but different. The emphasis is more on reasoning and application than on reproducing facts. The open-book exam gives more room, but the scenario questions require genuine understanding.
Can I still start with the old IG1/IG2 system?
Only if you sit the exam before 6 August 2026. After that, only the new GIC1/GIC2 system applies.
What is the difference between GIC1 and GIC2?
GIC1 is the theory open-book exam (24 hours). GIC2 is the practical assignment in which you carry out a risk assessment of your own workplace.
Does GIC2 count towards my final grade?
No. Your final grade (Pass, Credit or Distinction) is determined by GIC1. GIC2 must still be passed — without GIC2 there is no certificate.
When does the next NEBOSH IGC course start at SafetyXAcademy?
The next group starts in September 2026. You can enroll via the website.
