This blog will uncover everything you would ever need to know about the NEBOSH Diploma. The blog will analyse who the course is for, the organisational benefits and learning outcomes, and much, much more. 

So let's get started!

1. What is the NEBOSH Level 6 Diploma?

In a nutshell, the NEBOSH Level 6 Diploma is the highest level of qualification for people who want to become top-notch experts in workplace safety and health. 

The course was first made in 1980 and has been trusted by organisations all around the world. It covers a wide range of topics, such as understanding safety laws and regulations, assessing, and managing risks in the workplace, ensuring that people are healthy and safe on the job, and creating a culture of safety in organisations. 

1.1 Who is the NEBOSH Diploma Course For?

The NEBOSH Level 6 Diploma is broadly accessible as a comprehensive health and safety management course. The knowledge and understanding can be applied in virtually every industry, ensuring human safety and enhanced competence and regulatory compliance. 

However, the course is tailored to work more effectively with individuals already in management or supervisory roles. Due to the weighty nature of the course, it demands a degree of prior knowledge in health and safety. We recommend that learners considering the NEBOSH Level 6 Diploma take the NEBOSH General Certificate first. The NEBOSH General Certificate introduces topics more comprehensively in the NEBOSH Level 6 Diploma. 

People taking the course are often professionals serious about making workplaces safer. They may be experienced safety managers, consultants, or those looking to take on leadership roles in health and safety. It's a challenging and comprehensive program that helps you become an expert in keeping people safe at work and can open up excellent career opportunities in this field.

It is widely believed the NEBOSH Level 6 Diploma is perfect for the following roles;

  1. Experienced Health and Safety Professionals: The NEBOSH Diploma is typically taken by professionals with a solid health and safety foundation seeking to advance their careers. It's often viewed as a progression from lower-level NEBOSH certifications.
  2. Aspiring Health and Safety Managers: Individuals who desire to take on leadership and management roles in health and safety departments within organisations can benefit significantly from the NEBOSH Level 6 Diploma. It equips them with the knowledge and skills required to manage health and safety at a strategic level effectively.
  3. Risk Managers: Those responsible for risk management within an organization, including identifying, assessing, and mitigating risks, can find the Diploma particularly valuable. It provides a comprehensive understanding of risk management principles.
  4. Compliance Officers: Individuals responsible for ensuring that the organisation complies with health and safety regulations and legal requirements can benefit from the in-depth knowledge of regulations and compliance provided by the Diploma.
  5. Safety Consultants: Safety consultants and advisors who work with multiple organisations (potentially in a freelance capacity) can use the Diploma to enhance their expertise and credibility. It can help them provide more valuable guidance to their clients.
  6. Occupational Health Professionals: Those in the field of occupational health, including occupational health nurses and physicians, can benefit from the Diploma as it covers aspects of occupational health and industrial hygiene.
  7. Human Resources (HR) Professionals: HR professionals often deal with issues related to employee health and safety, so having a NEBOSH Level 6 Diploma can be beneficial in managing these aspects of HR responsibilities effectively.
  8. Career Changers: People looking to transition into a health and safety management career can take the NEBOSH Diploma to establish their credibility and competence in the field.

2.2 How Will My Organisation Benefit With the NEBOSH Level 6 Diploma?

The NEBOSH Level 6 Diploma provides a deep and comprehensive understanding of health and safety principles and practices.

The course provides staff with forensic oversight on legal requirements and health and safety regulations compliance. Organisations benefit from well-versed employees in these areas and can help ensure the company operates within the law, reducing the risk of legal issues and penalties.

Understanding and effectively managing risks is fundamental to the NEBOSH Level 6 Diploma. Organisations can benefit from individuals who can identify, assess, and mitigate risks, which can help prevent accidents, injuries, and incidents, thereby improving overall workplace safety.

3. Progressing From the NEBOSH General Certificate to the NEBOSH Diploma: What's Next?

The NEBOSH Level 6 Diploma is the natural older sibling of the NEBOSH General Certificate. The General Certificate introduces most of the areas featured in the Diploma course, but the Diploma comprehensively covers everything in much more detail. 

We strongly advise that learners only sit the NEBOSH Level 6 Diploma course after passing the NEBOSH General Certificate course. 

The NEBOSH General Certificate is a Level-3 vocational qualification equivalent to a UK A-Level. Meanwhile, the NEBOSH Diploma is a Level-6 vocational qualification equivalent to a UK university Degree. So, it’s important to understand that the jump is substantial. 

But let’s compare some other aspects of the two courses.

6. Understanding the NEBOSH Level 6 Diploma Assessments

The NEBOSH Level 6 Diploma is split into three different chunks;

  • DN1
  • DN2
  • DN3

Each section has its own assessment. So, let’s start at the beginning with the DN1 Assessment.

6.1 Understanding the DN1 Assessment

DN1 is an assignment split over two papers. Paper one holds the simulation questions, whilst paper two holds the workplace activities, reflective tasks and a research project. We urge learners to approach the DN1 papers, after finalising a revision plan that covers the contents of the papers. 

6.1.1 Stage One: Workplace Scenario-Based Case Study Task

Learners will be presented with case studies which engineered to provide real-life scenarios to assess and provide your professional opinion. You will be presented with an in-depth scenario that replicates real life. This scenario could be wordy, totalling several sides of A4 paper. 

6.1.2 Stage 2: Workplace-Based Tasks

This assessment lets you showcase your knowledge and understanding of your work environment. It asks you to put your learning into practice and analyse a working environment with a critical eye. 

6.1.3 Stage 3: Reflective Tasks

During this stage of the assessment process, you will be asked to reflect on your personal or work life, demonstrating your leadership and communication skills.

6.1.4 Stage 4: Short Research Project

To conclude the assessment stage, you will be asked to research a specific topic and answer a question. Your answer will be in the form of a report allowing you to display your knowledge and opinions on the subject.

6.2 Understanding the DN2 and DN3 Assessments

Units DN2 and DN3 are each assessed with a case-study and scenario based questions. You will have 2 weeks to complete each question paper and submit it for marking. We recommend you spend at least 20 hours on each paper (around 10 hours per week). DN2 and DN3 are each worth 175 marks, and you require at least 50% to pass.

We cover every aspect of the DN1, DN2 and DN3 assessments and how to pass them in our blog. Alternatively, you can watch Astutis Technical Director and former NEBOSH Diploma tutor, Brenig Moore, as he offers his personal advice on how to approach the examination/assessment process
