NEBOSH National Diploma in Occupational Health and Safety

Designed to provide students with the expertise required to undertake a career as a safety and health practitioner and also provides a sound basis for progression to postgraduate study.

Course Overview

All occupational health and safety practitioners (OHASPs) need to have a common core of knowledge in order to practise effectively. The NEBOSH National Diploma aims to provide the knowledge and understanding that underpins competent performance as an OHASP.

The NEBOSH National Diploma is the qualification for aspiring health and safety professionals, building directly upon the foundation of knowledge provided by the NEBOSH National General Certificate. It is designed to provide students with the expertise required to undertake a career as a safety and health practitioner and also provides a sound basis for progression to postgraduate study.


The NEBOSH National Diploma qualification meets the academic requirements to apply for Graduate Membership (Grad IOSH) of Institution of Occupational Safety and Health (IOSH). This is the first step to becoming a Chartered Health and Safety Practitioner as a Chartered Member of IOSH (CMIOSH). It also accepted by the International Institute of Risk and Safety Management (IIRSM) as meeting the academic requirements for full membership (MIIRSM). Holders of the NEBOSH National Diploma in Occupational Health and Safety may use the designatory letters “DipNEBOSH” after their name.

Those who hold the NEBOSH National Diploma are eligible to apply for the CSCS Academically Qualified Person (AQP) yellow/white card whilst they gain vocational qualifications or membership of a recognised professional body. This card is valid for five years and is currently non-renewable. All applicants must still pass the CITB Managers and Professionals Health, Safety and Environment Test.
