Today marks a very important event in the assessment of health and safety competency. 

NEBOSH, the National Examining Board for Occupational Safety and Health are re-launching the benchmark qualification for EHS Professionals, The National Diploma in Occupational Safety and Health.

The new qualification will be called the NEBOSH National Diploma for Occupational Health and Safety Management Professionals, but its way more than just a title change.

For many years Make UK have been helping EHS professionals to complete the NEBOSH Diploma and then supported them in the onward journey to Chartered membership of IOSH. We realised a very long time ago that this qualification is about individuals climbing the competency ladder and maximising their value to their organisations. We believe that this completely re-written qualification is absolutely centred around the learner. 

What’s so different?

Well, first of all there are now only 3 units, rather than the old 4. Unit ND1 replaces the old Unit A, ND2 replaces B and ND3 replaces C. Unit D has been removed all together. But, the real changes are in the detail.

In my experience of delivering the Diploma for over 10 years, Unit A was always the biggest challenge and the Unit that frightened most students. This was mainly because of the requirement to be able to recall details of multiple civil and criminal cases and then use them to answer questions in a 3 hour written exam. No more of this in the new Diploma. Most legal content has been completely removed and replaced with the requirement to have completed the NEBOSH Certificate in order to enrol on this course. Assessment methods have also changed, but more on that later.

ND2 and 3 have also changed and are now more about principles that remembering the specifics of Asbestos management or CE marking.

What about the assessment methods?

Without a doubt, the biggest change is in the assessment methods. NEBOSH have completely done away with the 3, 3 hour written exams and the 10,000 word dissertation and replaced them with 2 open book on-line assessments (similar to the NEBOSH Certificate) which students get a month to complete. There is also a written report to be completed, similar to the old Unit D. This all means that the new Diploma takes 365 hours to complete compared to the previous 500.

It is important to note that if you are already a student and have already sat an exam, you have to stay on the old syllabus and assessments methods until you complete the course. But if you are a new student, you will automatically enrol on the new syllabus. If you have started the course, but haven’t sat an exam yet, you can also transfer.
