Units IA, IB and IC of the NEBOSH International Diploma are each assessed via one three-hour written examination. Unit ID is assessed via a written assignment of approximately 8,000 words.

Exams are held each January and July. We have exam centres in more than 80 countries worldwide, and we make all the arrangements for you.

All of our courses contain plenty of exam practice to ensure you are fully prepared for the exam.

Many of our trainers are also NEBOSH examiners, so they're well placed to provide advice and guidance throughout your course.
