NEBOSH
National Examination Board in Occupational Safety and Health
Globally respected health, safety and environmental qualifications.
What is the NEBOSH?
NEBOSH is a UK-based examination board whose health, safety and environmental qualifications are recognised by employers in more than 130 countries. Unlike the other exams here, NEBOSH is not a single test but a family of professional certificates and diplomas — and earning one is often a requirement for a career in health and safety.
The most popular is the NEBOSH General Certificate (and its International version, the IGC), an entry-to-mid-level qualification covering the principles of workplace health and safety, hazards and risk management. Above it sit the National and International Diplomas for safety professionals.
NEBOSH qualifications are studied with accredited learning providers and assessed through a mix of open-book examinations or scenario-based questions and a practical risk-assessment assignment carried out in a real workplace.
Who needs the NEBOSH?
- Safety officers, advisers and managers building a career in health and safety
- Engineers, supervisors and managers who need a recognised HSE qualification
- Employers' staff working toward compliance roles, often as a job requirement
Test format, section by section
Examination / scenario assessment · Varies by award
Open-book or scenario-based questions that ask you to apply health-and-safety principles to realistic workplace situations.
Tip: Practise applying the syllabus to scenarios, not just memorising it — NEBOSH assessments reward application.
Practical risk assessment · Completed in your workplace
A risk assessment of a real workplace, demonstrating that you can identify hazards and recommend controls.
Tip: Choose a workplace you know well and follow the marking criteria step by step.
Variants & versions
Popular awards include the NEBOSH General Certificate, the International General Certificate (IGC), the National and International Diplomas, plus specialist certificates in fire, construction, environmental management and process safety.
How the NEBOSH is scored
NEBOSH qualifications are graded Pass, Merit or Distinction rather than scored numerically. Each unit must be passed; the qualification is awarded once all units are complete.
| If you're applying for… | Typical score |

| Senior safety-professional roles | NEBOSH National or International Diploma |
Where and when to take it

How much does it cost?
Varies widely by provider, qualification and country.
How to prepare: a study plan
- Choose an accredited NEBOSH learning provider — you can't study NEBOSH outside one.
- Work through the syllabus actively, applying each topic to workplace scenarios.
- Practise past-style scenario questions under timed, open-book conditions.
- Plan your practical risk assessment early and pick a workplace you can access.
- For international candidates, strengthen the technical and academic English the written assessments require.
Common mistakes to avoid
- Memorising the syllabus instead of practising how to apply it to scenarios.
- Leaving the practical risk assessment too late or choosing an unfamiliar workplace.
- Writing vague answers that don't follow the command words in the question.
- Underestimating the written English needed for clear, complete answers.
How the NEBOSH compares
Within health and safety, NEBOSH is the best-known qualification internationally; IOSH offers shorter awareness-level courses, while NEBOSH certificates and diplomas are deeper, career-building qualifications. Many professionals do an IOSH course first, then a NEBOSH certificate.
NEBOSH is taught and examined in English and demands clear written explanation — we help international candidates strengthen the academic and technical English the assessments require, so language never holds back a strong answer.
