There are no mandatory qualification entry requirements, but it is strongly recommended that learners have undertaken and passed the NEBOSH General Certificate in Occupational Health and Safety. The syllabus assumes that learners will have this level of prior learning.
It is important that learners have a suitable 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 example, you will be able to understand the risk profile of your organisation and how risk should be managed. You will also be able to recognise a range of workplace health and safety hazards and recommend control measures so that residual risk from these hazards is as low as possible.
The qualification will also equip you with professional skills such as understanding how your leadership style can affect other people and the culture of the organisation, as well as being able to influence and negotiate with employees at all levels.
