What does the NEBOSH International Diploma cover?

What does the NEBOSH International Diploma cover?The NEBOSH International Diploma is modelled on the UK’s most popular qualification for health and safety professionals, the NEBOSH National Diploma.

The key difference between the International and National version is the application of legal requirements. Rather than being guided by a UK framework, the NEBOSH International Diploma takes a risk management approach based on best practice and international standards, such as the International Labour Organisation (ILO) codes of practice.

Local laws and cultural factors are also included when appropriate. It’s this best practice approach which makes it so appealing to global employers and helps make sure people all around the world at working to the same high standards.
