There are no formal entry requirements for this qualification, however learners should consider that this is a professional level qualification, set at SCQF Level 10. Therefore, to increase your chances of successfully passing your NEBOSH Diploma, the British Safety Council strongly recommends that you have prior learning gained through previous health and safety qualifications, such as the NEBOSH International General Certificate, before undertaking this course. The syllabus assumes that learners will have this level of prior learning.

If you do not hold such a recognised qualification, please contact [email protected] to discuss your options.

It is also vital that learners have an appropriate standard of English language in order to understand and articulate the concepts contained in the syllabus.

NEBOSH recommends that learners undertaking this qualification should reach a minimum standard of English equivalent to an International English Language Testing System (IELTS) score of 7.0 or higher in IELTS tests.

For further information please see the IELTS website.

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 DI1 – Know – Workplace Health and Safety Principles (International)

Unit DI2 – Do – Controlling Workplace Health Issues (International)

Unit DI3 – Do – Controlling Workplace Safety Issues (International)

The qualification is based on a minimum of 185 taught hours plus 144 recommended self-study hours and 80 assessment hours.

The qualification specification (syllabus) can be found here.

Unit DI1 An assignment split over two papers (both papers must be submitted at the same sitting):

• Paper 1 – simulation questions.
• Paper 2 – workplace activities, reflective tasks, and a research project.

Unit DI2 Case Study (simulation only)

Unit DI3 Case Study (simulation only)

Each unit is completed remotely accompanied by an online closing interview discussing your work. 

We anticipate that it will take you around 40 hours to complete the DI1 assignment and 20 hours each for the DI2 and DI3 case studies.

The time-period given for you to complete each assessment reflects this:

• Unit DI1: 4 weeks (20 working days)
• Unit DI2: 2 weeks (10 working days)
• Unit DI3: 2 weeks (10 working days)

The percentage marks of all three units are combined and the qualification grade is based on the following boundaries:
