All NEBOSH qualifications require learners to carry out their own private study. The recommended private study hours do vary for each qualification.

To find the recommended private study hours for each qualification, visit the qualification section of the website.


The “Qualifications can cross Boundaries” leaflet is published by the regulators in the UK and the Republic of Ireland. The document itself states under ‘how to use this leaflet’: “This makes it possible to draw broad comparisons, rather than direct equivalences, between qualifications and their levels for each country.”  It is a useful guide for comparing standards and difficulty of qualifications across frameworks but it is not intended to not make definitive statements about direct equivalence or specific exemptions.

While it provides a comparison for levels, the “Qualifications can cross boundaries” chart does not compare credit values, i.e. the length or size of the qualification, the amount of time that it would take a typical learner to complete the qualification or learning programme. This varies between qualification types and between specific qualifications.

The leaflet also states: “Entry requirements for jobs and courses often vary within a country. This means you will need to check the specific requirements with the employer or institution for the job or course that you are interested in”. It is ultimately the decision of the receiving organisation involved as to deciding whether or not to accept a particular qualification for exemption and the equivalent credit value they assign to an exemption for a specific programme.

    • the learner (e.g. due to illness, work/domestic problems, etc.), or
    • the Learning Partner (e.g. due to lack of proper facilities, changes in or shortages of staff, industrial disputes, etc.).

Where the circumstances prior to the assessment are of a temporary nature and are such that an effect on performance is reasonably foreseeable, the learner is advised to postpone the assessment until a later date.

Learners may be eligible for special consideration because of:

  • temporary personal illness or accident/ injury at the time of the assessment
  • bereavement at the time of the assessment; or bereavement occurring before the time of the assessment, where an anniversary has been reached at the time of the assessment or there are ongoing implications such as inquests or court cases

No. Once all the units of a NEBOSH qualification have been successfully completed, the qualification achievement does not expire and NEBOSH does not require qualifications to be periodically re-taken.

However, in a dynamic field such as health and safety, new legislation, standards, best practice and professional body requirements do evolve over time. As a result, NEBOSH qualification syllabuses are reviewed and updated regularly.

NEBOSH would recommend that longstanding qualification holders maintain a current knowledge of the subject area and would benefit from undertaking the latest version of the qualification to provide up-to date knowledge, understanding and workplace application. This is entirely optional.

Existing qualification holders who decide that they wish to update their knowledge by taking the most recent version of a qualification they already hold can obtain details of the current versions of NEBOSH qualifications here.

Learning Partners can be found using the search facility in the Where to Study section of the NEBOSH website.
