Qualification specification

Completing the qualification

 In order to achieve the qualification, you must pass all four units within a period of five years.

The clock starts on the date on which you are awarded the first unit, rather than the date on which you start the course.   So, if you are awarded Unit A on 20 March 2020, you have until 19 March 2025 to successfully pass the remaining three units.

Units can be completed in any order.

Examination preparation sessions

About a month prior to the examination, we run free examination preparation sessions. 

These are full-day for Unit A and half-day for Units B and C. 

At the session, your tutor will run through a series of past questions with you. 

Your British Safety Council Account Manager will advise you of the dates and make sure that you’re booked on. 


The Unit DNI assignment requires you to carry out a review of the arrangements for managing health and safety in your workplace and to produce justified, proportionate recommendations to improve health and safety performance.

We run a half-day assignment briefing in January and July.  Students normally complete their written examinations then attend an assignment briefing.  However, you are welcome to attend the assignment briefing at any point during your course.  

Following the briefing, you complete the 12,000-word assignment in your workplace.

There are four submission deadlines each year:

The last Wednesday in February
The last Wednesday in May
The last Wednesday in August
The last Wednesday in November 

You choose which deadline you want to hit and book your submission with your British Safety Council Account Manager.
