RRC's NEBOSH National Diploma FAQs

Can I transfer from the Current Diploma onto the new version?

There are no transitional arrangements so unit passes cannot be transferred.

If you have not yet passed any units RRC will allow our students to transfer until the end of July, subject to paying the additional NEBOSH fees involved. After that date there will be an additional administration fee. Contact us for more information.

If you have already passed Units on the current specification it is probably better to remain on the existing, soon to be old, syllabus. NEBOSH will be offering exams until 2026 (Last Unit A, B & C exams July 2026, last Unit DNI submission date is May 2026 ) and RRC will continue to support our Learners until then.

How do the assessments work?

The assessment is undertaken at home and in your workplace so there is no requirement to attend an exam centre. NEBOSH will issue the assessments twice a year for each unit which you will need to complete and return to them. For Unit ND1 NEBOSH are estimating it will take 60 hours to complete and are allowing 6 weeks for Learners to complete and submit the assignment. For ND2 & 3 NEBOSH are estimating it will take 40 hours to complete and are allowing 4 weeks.


  • Units ND1 is assessed by an assignment (in four parts - simulations, workplace based activities, reflective tasks and a research project). Part of the assessment will require learners to undertake some workplace-based activities so need to ensure that they select a suitable workplace/organisation.
  • Units ND2 & ND3 will be assessed by a case study (simulation only)

Assessment Dates

  • ND1 - Assessment release: 8 September 2021, to be completed by 20 October 2021
    Thereafter March and September each year
  • ND2 - Assessment release: 10 November 2021 to be completed by 8 December 2021
    Thereafter May and November each year
  • ND3 - Assessment release: 13 January 2022, to be completed 10 February 2022
    Thereafter January and July each year

How long does the Course take to complete?

NEBOSH advises that it will take approximately 475 hours to complete the course and assessments, see below for a more detailed breakdown.

For Classroom and Live Online courses this equates to 30 days taught (10 for each unit), plus self study and the assessments.

The assessments are structured so that it is possible to complete the course in 12 months, but given other demands on most people's time we would expect 18 to 30 months to successfully complete.

What are the entry requirements for the NEBOSH Diploma?

Whilst there are no formal entry requirements, the Diploma builds on the knowledge gained at Certificate level . This is not taught in the Diploma but will form part of the assessments, so you really need to have studied the NEBOSH General Certificate or equivalent level course before starting the Diploma. All RRC courses will include resources to refresh your knowledge on the Certificate but this is unlikely to be sufficient if you have not studied the course previously.

The Diploma is only available in English language and NEBOSH recommends the minimum standards of English as the International English Language Testing System (IELTS): 7.0 or higher.

Do I have to start with Unit ND1 of the NEBOSH Diploma?

Yes, knowledge is gained in this unit that is required to complete the unit 2 & 3 assessments.

What does Gold Learning Partner mean?

RRC are delighted to have been evaluated as a NEBOSH Gold Learning Partner, the highest level in the NEBOSH Learning Partner programme.

NEBOSH introduced a Learning Partner Programme in September 2019 which recognises those Learning Partners that provide learners with the best possible learning experience.  

All NEBOSH Learning Partners have been classified based on their performance against the programme’s principles which represent global best practice in the provision of course tuition and support. The key principles are:

  • Ensure all learners understand what is expected of them and what they can expect from their Learning Provider.
  • Create a learning environment that is engaging and encourages interaction that is appropriate for the course and type of delivery. 
  • Provide accurate course materials and continually update and improve them. 
  • Ensure tutors are qualified, knowledgeable, competent and engaging. 
  • Give learners feedback on their progress and provide appropriate support. 
  • Review course delivery and learner feedback and action as necessary. 

Learner Partner Status

Learning Partners can be identified as follows:

  • Gold - greatly exceeds the principles
  • Silver - exceeds the principles
  • Bronze - meets the principles

Can I try the online course before I enrol?

Yes we offer a demo and trial of one unit on our main webpage. You will need to sign up for this so we can provide access.

Can I pay the course fees in instalments?

Course fees can be paid in up to a maximum of four monthly instalments. For UK customers instalments can be paid over 10 months. Click here for more information.

What is the difference between the National and International Diploma?

The National Diploma is based on UK legislation and is recognised worldwide. The International Diploma is based on International Standards and Best Practice and is recognised by employers outside of the UK.

Can I get Chartered Membership of IOSH (CMIOSH) by completing the NEBOSH National Diploma?

NEBOSH anticipates that this qualification will meet the academic requirements to apply for membership of many professional bodies including the Institution of Occupational Safety and Health (IOSH) and the International Institute of Risk and Safety Management (IIRSM).

What is the difference between Live Online, Online, e-Learning and Distance Learning?

Live Online is delivered in real time through Zoom and is very similar to a Classroom course. The tutor will deliver the course with breaks to allow time for group work, exercises and private study.

Online & e-Learning are just different words for the same thing and mean a flexible self study course delivery with tutor support you can access via email. Distance Learning, means learning at a distance but is commonly used to describe the more traditional paper based study, RRC do provide the complete study text which you can download and study off line thus giving you the option of how you study the course

What educational level is the NEBOSH National Diploma?

It is anticipated that NEBOSH National Diploma for Occupational Health and Safety Management Professionals will be accredited and credit rated by the Scottish Qualifications Authority (SQA) Accreditation at SCQF Level 10 with 48 SCQF credit points.

SCQF Level 10 is comparable to RQF/CQFW Level 6 in England, Wales and Northern Ireland.

What happens if I fail the assessments?

You will be able to retake the assessments, but you will need to pay the NEBOSH assessment fee again along with a small RRC administration fee.

Do we have a graduation Ceremony?

Yes, all candidates who successfully complete the NEBOSH National Diploma are invited to attend a Graduation Ceremony. The 2022 Graduation will be held in Birmingham, and invitations have already been sent by NEBOSH. If you believe you are eligible to attend, but have not received your invitation, please contact NEBOSH directly.

Do I have to pay VAT if I am based outside the UK?

Only companies outside of the UK who can provide a valid VAT number will be exempt from VAT. All individuals irrespective of their location will have to pay VAT.

Would I be able to get past assessment papers?

NEBOSH will be producing extensive guidance on the assessments and examples. In the longer term past assessments will be available for reference along with examiners reports.

However given this type of assessment previous papers have little value other than demonstrating the approach NEBOSH are taking with the assessment.

Guidance for CSP qualified students

There is no information yet as to whether the previous agreement for CSP holders is valid with this new syllabus.

Am I eligible for TOTUM Pro membership?

Yes, when you study the NEBOSH National Diploma with RRC you are eligible to sign up for TOTUM Pro. This is a discount scheme that gives you access to exclusive discounts, offers and vouchers from hundreds of retailers. You can find out more about the scheme here.
