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, with special reference to model such as the ILO's "Guidelines on Occupational Safety and Health Management Systems" (ILO-OSH 2001). Underpinning knowledge of legal frameworks is included and local laws and cultural factors should form part of the study programme where relevant and appropriate.
It provides the core health and safety knowledge which, combined with understanding and appropriate application, underpins the competent performance of an Occupational Health and Safety Practitioner.
The qualification is divided into four units, each of which is assessed separately:
In four units, three assessed by written examinations of three hours’ duration (Units IA, IB and IC) with the assignment unit designed to test knowledge across the syllabus, assessing application of health and safety theory and practice (Unit ID).
On successful completion of the qualification, the Diploma holder may apply for Graduate membership (Grad IOSH) of the Institution of Occupational Safety and Health (IOSH), the major UK professional body in the field.
The qualification also meets the academic requirements for Member status (MIIRSM) of the Institute of Risk and Safety Management (IIRSM).
Holders of the NEBOSH International Diploma in Occupational Health and Safety may use the designatory letters “IDipNEBOSH” after their name and are invited to the annual NEBOSH Graduation and Awards Ceremony in the year following the successful completion of their award.
