The NEBOSH International Diploma is an advanced qualification. You should already understand fundamental health and safety principles such as risk assessment, hazard control, accident investigation, and key regulations.

You’ll also need to have a good level of communication to critically analyze information and apply it to any given scenario.

We always recommend taking the NEBOSH International Certificate in Occupational Health and Safety before taking the International Diploma to ensure you can meet the demands of the course.

You need to have a foundation understanding of health and safety principals before taking the NEBOSH International Diploma. It is strongly recommended that you take the NEBOSH International General Certificate or have at least 5 years experience working in a health and safety role to increase your chance of passing.
The NEBOSH Diploma course is available in two versions. National for UK based learners and International for learners outside the UK. Both courses are equal to one another however the syllabus is slightly different and is tailored to legislation in different parts of the world.
Choosing a provider for the NEBOSH International Diploma can be tough. There are a lot of providers to choose from and you want to ensure you get the most from your money. Astutis' advice is to look at online reviews and testimonials to see what past learners think. You could also try to understand what their average pass rates are - this reflects on the quality of training and learning support. Reviewing what learning material you will have access to and whether or not the provider offers a learning method that's right for you is also really important.
The NEBOSH International Diploma is a level 6 qualification which is equivalent to a foundation level degree. According to the National Qualifications Framework, this equates to around 2/3 of a full bachelor's degree.
All Astutis tutors are experienced health and safety professionals and leaders within their field. With vast industry knowledge gained from experience, our tutors are also educationalists who hold teaching qualifications, masters degrees or doctorates. Additionally, as NEBOSH examiners they are ideally placed to guide and coach delegates to ensure success. For those studying online, with our award-winning LMS, delegates are able to further interact outside of the classroom by way of our tutor-led discussion forum and notice boards. Tutors are able to pose questions and guide conversation to further develop thinking around particular topics. Online learners anywhere in the world will gain free access to revision webinars as part of their course and all Astutis delegates will be assigned a tutor on enrolment who will be on hand to answer questions on a one-to-one basis via telephone or email.
