What exams are there for the NEBOSH International Diploma?

IDip exam paperUnits IA, IB and IC are each assessed with a 3-hour written exam. Each exam paper is split into two sections; A and B.

Unit DNI is a written assignment set by NEBOSH. You’ll be required to write an 8000 word report which demonstrates your knowledge of all other units; IA, IB and IC.

Sitting your NEBOSH International Diploma exam

Register for your NEBOSH exams with AstutisYour course provider will have given you all the details of your exam such as location, time and date. It’s important to give yourself plenty of time to arrive before your exam starts, you don’t want to turn up all flustered minutes before the exam starts.

You’ll sit your exam under exam conditions. You’ll be asked to present photographic ID (passport or driving licence) which the exam invigilator will check against your candidate number and then give you your answer book.

Your answer book simply contains lined paper with a square in the top of each corner where you write the number of the question you’re answering. You won’t need to fill anything in on the front; it’ll already be pre-printed with your name and candidate number.

The invigilator will then hand out the exam question papers and give you 10 minutes reading time. You won’t be able to write anything in your answer book during this time, instead you should use this time to read all of the questions and begin making notes to plan your answers.

Once your 10 minutes reading time is up, the invigilator will let you know that the exam has started; you’ll have exactly 3 hours. They’ll also let you know when the exam will finish, usually by writing the exam finish time on a board or flipchart. There’ll be a clock in the room for you to keep an eye on the time and the invigilator will also give you reminders at key times to help keep you on track, i.e. when an hour has passed and when you have 30 minutes remaining.  

What do I need to pass my NEBOSH International Diploma?

You have to pass all 3 written exams and the assignment to achieve your full NEBOSH International Diploma.

The actual pass mark can vary, but it’s usually set at 45% for written exams (Units IA, IB and IC) and 50% for the assignment (Unit DNI). Once you’ve passed all four units, your marks will be added together and you’ll be awarded your final qualification grade:

  • Pass 185 – 239 marks
  • Credit 240 - 279 marks
  • Distinction 280+ marks

NEBOSH International Diploma Exam Dates

NEBOSH International Diploma written exams are held in the 3rd full week of January and July every year. Whether you’re taking your course in a classroom or online, you’ll still take your exams on these dates.

Written exams are held in the mornings at 9:30am on Tuesday (Unit IA), Wednesday (IB) and Thursday (IC). For Unit DNI, there are four submission deadlines spread out throughout the year in February, May, August and November.

You’ll have 5 years to sit your exams and submit your assignment, so you don’t have to take them all at the same time. You can split your exams and assignment out across different months or even different years, providing you pass them all within the 5 year timeframe.

Registering for your NEBOSH International Diploma Exam

Once you’ve chosen your exam or submission date, you’ll need to let your course provider know in plenty of time so that they register you with NEBOSH. You’re usually required to give 12 weeks notice, but it’s always a good idea to check these fine details at the time you book your course.

NEBOSH will also send you regular reminders throughout your course of exam and assignment registration deadlines. 

When will I get my NEBOSH International Diploma exam results?

NEBOSH will email you your results within 12-14 weeks of sitting your exam. They’ll use the email address that you put on your booking form, so make sure you double check it’s typed correctly. If you haven’t received your results in that time then contact your course provider and they’ll be able to help.

Your hard copy certificate will be sent out shortly after you receive your results and will display your final qualification grade; pass, credit or distinction.
