Course overview

The NEBOSH International Diploma in Occupational Health and Safety gives learners the skills and knowledge to competently manage and control all aspects of health and safety, enabling them to reduce risk, raise standards and improve efficency in their company.

As gloablisation increases, governments and employers are recognising the need for a common and consistent standard for achieving and maintaining the health and safety of workers in all parts of the world. Based on international standards, the NEBOSH International Diploma provides a recognised level of practice that helps to improve safety standards and advance the profession on a global scale. 

How is it different to the NEBOSH National Diploma?

The NEBOSH International Diploma is modelled on the NEBOSH National Diploma. The key difference is the application of legal requirements. Rather than being guided by UK legislation, 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 global best practice approach which helps make sure people all around the world are working to the same high standards.

Who is the NEBOSH International Diploma for?

The NEBOSH International Diploma is for health and safety professionals working outside of the UK looking to develop their knowledge and skills to an advanced level. 

Learners should already have a foundation-level qualification, such as the NEBOSH International Certificate, and/or have at least 5 years’ experience in the field.
