National Diploma for Occupational Health and Safety Management Professionals

The NEBOSH National Diploma is accredited by the Scottish Qualifications Authority (SQA) at level 10 in the Scottish Credit and Qualifications Framework (SCQF). For users in England, Wales and Northern Ireland, this is comparable to a vocationally-related qualification (VRQ) at Level 6 in the Regulated Qualifications Framework (RQF). In academic terms, a Level 6 VRQ is comparable to an honours degree.

This unit covers moral, economic and societal drivers, health and safety law and management systems, organisational structures and leadership, behavioural change programmes, risk perception, human failures and reliability, hazard identification techniques and loss causation

The NEBOSH Diploma is an advanced qualification and an equivalent to a Foundation level Degree. Therefore, to increase your chances of successfully passing your NEBOSH Diploma, British Safety Council strongly recommend that you have prior learning gained through previous health and safety qualifications, such as the NEBOSH National General Certificate, before undertaking this course. If you do not hold such a recognised qualification, please contact [email protected] to discuss your options. Please also see the recommend knowledge required by NEBOSH here.

Assessments are available in English only. Your standard of English must be such that you can both understand and articulate the concepts contained in the syllabus. NEBOSH recommends that non-native speakers undertaking this qualification should have a minimum standard of English equivalent to an International English Language Testing System (IELTS) score of 6.0 or higher in IELTS tests. For further information please consult the IELTS website: www.ielts.org

When you start the course, we enrol you as a student with NEBOSH. Your initial enrolment period lasts for 5 years. This means that you must pass your first unit within 5 years. If you fail to pass your first unit within 5 years, you will need to re-enrol and pay another registration fee.

When you pass your first unit, your enrolment period is automatically re-set and you have a further 5 years to pass the remaining unit. In other words, your first unit has a shelf-life of 5 years. If you do not pass the remaining unit within 5 years, your first unit will expire and you will have to retake this unit in order to pass the qualification.

The NEBOSH Diploma comprises three units:

Unit DN1 – Know – workplace health and safety principles

Unit DN2 – Do – controlling workplace health issues

Unit DN3 – Do – controlling workplace safety issues

Total hours 191

A programme of study is based around a minimum of 191 taught hours and approximately 144 hours of self-study for an overall total of 335 hours (excluding assessment time).

The qualification specification (syllabus) can be found here.

The qualification comprises of three assessments:

Unit DN1 Assignment (in four parts - simulations, workplace-based activities, reflective tasks and a research project)

Unit DN2 Case study (simulation only)

Unit DN3 Case study (simulation only)

Each unit can be completed remotely accompanied by an online closing interview discussing your work.  We anticipate that it will take you around 60 hours to complete the ND1 assignment and 40 hours each for the ND2 and ND3 case studies.

Unit DN1: 4 weeks (40 hours)

Unit DN2: 2 weeks (20 hours)

Unit DN3: 2 weeks (20 hours)

The grading is based on the combined percentage mark for the 3 units. All three units must achieve a pass in order to be awarded the qualification. Once all three unit assessments (DN1/DN2/DN3) are passed, a combined percentage mark will give an overall grade for the qualification (Distinction/Credit/Pass).

Distinction 226 or higher

Credit 196 – 225
